"We shall do all that we can to aid her, for she bears our legacy as she bears the ancient armor and weapons of our people."

"The Chozo... Over millennia, this bird-like race of creatures made incredible technological and scientific leaps. Traveling at will through space, they built many marvels across the Universe. Technological wonders of unfathomable complexity and cities unmatched in beauty. They shared their knowledge freely with more primitive cultures and learned to respect and care for life in all its forms. Even as their society reached its technological peak, the Chozo felt their spirituality wane. Their culture was steeped in prophecy and lore, and they foresaw the decline of the Chozo coinciding with the rise of evil. Horrified by the increasing violence in the universe, they began to withdraw into themselves, forgoing technology in favor of simplicity. Tallon IV was one of the several refuges they built — a colony bereft of technology, built of natural materials and wedded to the land and its creatures."

— Metroid Prime Manual

A mysterious race of avian humanoids known for their highly-advanced technology and mystical wisdom. Having colonized many worlds in their millennia of civilization, they interacted with other advanced races such as the Luminoth and the Reptilicus, and later had a role in the formation of the Galactic Federation. They adopted a young Samus into their culture, training and providing her with the iconic Power Suit. They're also responsible for leaving most of the various Power Suit modules Samus finds in her adventures, knowing that she will need them to save the galaxy from whatever threat she is fighting at the time. Unfortunately, two of the greatest threats the galaxy faced, the Metroids and Mother Brain, were also creations of theirs....

In General

• Ascended Extra:
  • They were first depicted through the reclining statues that appeared throughout Zebes and SR388 in the first three games, with the nature of the statues' creators left ambiguous. It wouldn't be until the Super Metroid comic, and later the instruction manuals and lore of Fusion and Prime, that their role as Precursors who raised Samus and created the Metroids would be fully established.
  • Done even further in Metroid Dread, where a faction of Chozo are directly involved in the plot, with their leader being the main antagonist.
• Ascending to a Higher Plane of Existence: The logbook in Metroid Prime said they did this, or at least the Tallon IV Chozo did. It's unknown if this is true for the other Chozo tribes or an exclusive characteristic of the nature-loving Tallon IV inhabitants.
• Benevolent Precursors: While it is true that they weren't able to do much in their own lifetimes, they actively worked to put in place a system for Samus to redeem them by seeding various worlds with power suit upgrades for her to collect. According to the manga and the "Metroid Dread Report", they also did everything they could to bring lasting peace to the galaxy in other ways knowing they wouldn't be around for much longer. In Metroid Prime, there is a scannable Chozo Statue in the Chozo Ice Temple of the Phendrana Drifts that depicts said Chozo holding and balancing a large flat dish meant to represent "the plane of existence", implying they saw it as their spiritual duty to try and uphold order in the universe.
• Beware the Nice Ones: Samus and the Metroids are proof enough that you do not want the Chozo mad at you.
• Bird People: The Chozo are bipedal avians. Their Japanese name chōjinzoku literally translates to "bird-man tribe".
• Canon Immigrant: Old Bird, one of Samus's Chozo mentors/adoptive parents, appears in the Japanese version only endings of Metroid Fusion (which you can thankfully unlock in any version of Zero Mission), and makes a blink-and-you'll-miss-it cameo appearance in Metroid Zero Mission in one of Samus's flashbacks. Old Bird first appeared in the Nintendo Power Super Metroid comic and was later imported to the manga (along with Chairman Keaton and Chief Hardy). Some speculate that the second Chozo in the engraving at the end of the game may be Aran's other Chozo mentor, Gray Voice.
• Conlang: Metroid Dread introduces a Chozo language with both written and spoken forms, which combines largely Arabic/Akkadian-inspired phonetics with grammar based on a simplified form of English. The script used on ZDR is an alphabet of triangular symbols, which are mirrored vertically so that characters in a sentence point alternately up and down. Samples of Chozo writing had appeared in previous games, but with different scripts (justified by it being on different planets) and no evidence of an underlying language framework.
• Doom Magnet: Whatever they touch, be it planet, species, or individual, is universally ill-fated in some way. Planetary destruction and being driven to the brink of extinction happen a lot where they've been. With all the goodies they left behind, it's mostly because their leavings attract Space Pirates.
• Early-Installment Weirdness: Comics and manga made around the time of Super Metroid portrayed them as Exposed Extraterrestrials much like their statues. It later turned out that the statues were heavily stylized depictions of them; living Chozo shown in flashbacks and later manga were fully clothed in either fancy robes or Power Suits.
• Earth-Shattering Kaboom: This is a common tactic used by the Chozo when things go south. Old Bird once considered destroying Zebes to prevent the planet from falling to the Space Pirates, but decided it was better to flee. And the Thoha tribe attempted to destroy SR388 as a last ditch attempt to get rid of both the Metroids and the X Parasites only to be betrayed by Raven Beak and the Mawkin tribe. Suddenly, Samus' tendency to blow up planets doesn't seem to be so coincidental anymore.
• Endangered Species:
  • In the manga, it is implied that the only remaining Chozo are the handful on Zebes and they are basically trying to finish their work on "Metroid" before they go extinct. The games are more vague but make it clear the Zebes Chozo were just one small group of a nomadic civilization, that may be endangered, extinct or simply out of reach. Volume 3 of the "Metroid Dread Report" states that there are a few still alive and sighted by the other peoples of the galaxy, but they "mostly try to avoid attention" nowadays.
  • Metroid Dread further confirms this. Raven Beak and Quiet Robe are the last living members of their respective tribes, the Mawkin and the Thoha. The latter were annihilated by the former due to a disagreement about the handling of the Metroids that the Thoha created, while the Mawkin got wiped out by a X Parasite that managed to infect one of their ranks. During the events of the game, both characters perish, rendering the two tribes completely extinct except for Samus, who bears DNA from both.
• Friend to All Living Things: The only creatures they ever had to take action against were the X. Every other species was fine to them, as shown by the wildlife on Zebes and Tallon IV.
• The Ghost: Sometimes literally. While one of the key elements of the series' and Samus' background, they've never been encountered in the games due to most of the race having died off. The most Samus has seen are abandoned colonies, old journals and research logs, or sometimes literal ghosts driven mad by Phazon poisoning. It isn't until Metroid Dread that she finally encounters living Chozo in the present — but as the second trailer shows, this group of Chozo isn't friendly.
• Gone Horribly Wrong: Both the Metroids and Mother Brain were created by the Chozo to make SR388 and Zebes nicer places to live. In both cases, the Chozo got a lot more than they bargained for.
• Idiot Ball: This is what the manga says brought down their civilization. When their technology had advanced to the point they could live for hundreds to thousands of years with near perfect health, they started to really get caught up in their own desires (at this point, they were still warriors), but despite the fact they could live long, they started feeling the effects of old age and had to give that up. It was only then that they realized that their entire civilization had squandered their youth and forgot to reproduce while it was possible. As a result, they became the peaceful scientists who helped form the Galactic Federation as a measure of immortality for their species as they started a near millennium of watching their own civilization die.
• Immortal Procreation Clause: Due to their great longevity, old age wreaked havoc on their ability to reproduce, causing a steep decline in their numbers.
• Maybe Magic, Maybe Mundane: Their interactions with the Reptilicans of Bryyo proves they had enough knowledge of magic to forewarn against the conflict between magic and technology. After the Chozo's disappearance much of their technology is successfully reverse-engineered by the Space Pirates and the Federation, but certain Chozo designs leave them completely stumped. The Federation's attempts to replicate Samus's power suit resulted in gigantic unwieldy mech suits, and the Space Pirates morph ball prototypes wound up horribly maiming their test subjects. Whether Samus's suit has magical aspects, is simply technology far beyond the current level, or if a difference between the two even applies is left open to interpretation.
• Mistaken for Granite: The first Chozo Statue in Super Metroid seems inanimate until you take the powerup it holds and try to leave, at which point the exit seals and it attacks you.
• Neglectful Precursors: Zigzagged. Not even they, with all their technical and spiritual skill, have what it takes to take care of the doom that follows them around like a puppy they fed, leaving it all for Samus to clean up. On the other hand, they have limited ability to make prophecies, and make a point of preparing for each one they find feasible. The Tallon IV colony stocked up their ruins with power suit upgrades specifically to help Samus save the day in the future, and it's implied that the Chozo on other worlds did the same.
• Organic Technology: Much of the Chozo technology we see appears to be at least partially organic in nature. Samus's suit has "organic components" that enable the X parasites to infest and duplicate it. The Torizo are shown both to also be replicable by the X, and to have Life Energy that a Metroid is able to drain. Finally, the Elysians are able to be corrupted by Phazon. It's telling that the Chozo's solution to the X Parasite was to create an X-immune life form which could hunt it, rather than some non-biological method of containment.
• Perfect Pacifist People:
  • The Chozo have evolved to a point in which they live in harmony with nature, shunning violence and destructive technology. Of course, they were warriors once, and were able to create the advanced armor that Samus uses.
  • Subverted in Metroid Prime, where the Chozo were content to live in peace on Talon IV and on their "higher dimension" after ascending, but once Phazon pulled them back down in rough approximations of their former bodies they got to work building combat capable machines and even took the fight to Space Pirates directly.
  • In the manga, the present Chozo race has a mental block against violence — harming sentient beings for any purpose causes a Chozo to experience immense pain or even death. Training Samus to do it is fine, though.
  • Subverted in the secret Chozo Memories ending in Samus Returns. While it's very vague about what happened, it's clear that at least one tribe that is not above killing their own peers. They're later revealed to be the Mawkin tribe, the main antagonists of Metroid Dread. The Chozo tribe who created the Metroids also included a work-around in the form of bioweapons.
• Powered Armor: One of their most iconic technologies is the Power Suit, advanced armor that greatly enhances a wearer's strength, speed, and agility and can absorb new abilities from artifacts and defeated enemies. Statues, murals, flashbacks, and the Chozo Soldiers fought in Metroid Dread show that Chozo warriors almost all wore such armor, visually distinguished by a predominantly orange color scheme, large round pauldrons, and occasionally an Arm Cannon. The most famous Power Suit is the one they gave Samus.
• Powers as Programs: Zero Mission artwork describes the Chozo as having developed into three tribes - one that could run quickly, one that could leap great distances, and one that could curl into a ball. The upgrades Samus collects pass on the physical abilities of these tribes to her.
• Precursors: They seem to zigzag all the precursors tropes. Their neglectfulness is mentioned below, their Abusive Precursors status is established by the fact they made the Metroids, then subverted into Benevolent Precursors both by the below mentioned upgrades, and the fact they originally made the Metroids to stop something worse. Dread justifies this by making it clear that the Chozo were divided into several tribes (or "hasana", as they called them), each with their own cultural priorities.
• Proud Warrior Race Guy: What they used to be. Prime shows they consider Samus's weapons to be ancient, but whether that has to do with being primitive to them at this point or simply because no one's bothered to choose the warrior's path for so long is up for debate. However, the Mawkin Tribe chose to stay this way, going as far as to slaughter their peaceful brethren, and their leader is Raven Beak, who is the Big Bad of Metroid Dread.
• Psychic Powers: Of the subtle variety.
• Religious Bruiser: Downplayed in both respects. The Chozo as a whole don't seem to truly be religious in that they had a central faith or figure to believe in, but rather that they were deeply spiritual and contemplative about their place in the universe as evidenced by their many temples. As for "bruiser", while in the present many Chozo seem to be pacifists it's made clear they were once a dominant warrior race and they never lost their touch at building advanced weapons.
• Space Elves: In their warrior phase they were essentially Space Tengu.
• Steampunk: They have done some dabbling in this, as seen by the observatory they left on Elysia.
• Sufficiently Advanced Aliens: A major reason why Samus's suit has such impossibly advanced technology is because these guys didn't have to worry much about regular physics.
• Technical Pacifist: Chozo themselves are incapable of harming other lifeforms. There are no such restrictions on them creating things to do the violence for them. Just ask Samus, the Metroids, and any of their defense systems.
• Tengu: Due to being a race of avian humanoids that live in isolation far from others, they're this to a tee right down to an ascetic philosophy and martial tradition similar to those of warrior monks. The biggest difference is they aren't as mischievous as traditional tengu, being benevolent teachers to younger races and guiding galactic civilization. However, the Chozo Memories of Samus Returns show there is a tribe, the Mawkin Tribe, that is far more aggressive.
• Wide-Eyed Idealist: They tried many times to get the Galactic Federation to demilitarize and become a more peaceful civilization, but their points were always ignored because of threats like the Space Pirates looming. The Chozo themselves had no real alternative to this, other than Samus.

Individual Chozo

Old Bird

"There’s nothing to fear. We look different, but inside we have the same heart that you do.”

Debut: Super Metroid (comic)

One of the Chozo who served as an adoptive parent to Samus after she was orphaned, and also trained her.

---

• All-Loving Hero: He believes all conflict can be ended by understanding the other side and reaching a mutual agreement, though he's not completely naïve and acknowledges that violence can't be ended soon.
• All There in the Manual: His characterization is limited to the canon manga.
• But Now I Must Go: Inverted. Once Samus' physical training is complete, he tells her that the mental training she needs can only be achieved through her own efforts and that she must walk her own path.
• Canon Immigrant: He was introduced in a Nintendo Power Super Metroid comic and given an extensive role in the Metroid prequel manga before he made his debut in the games themselves with Zero Mission.
• Cool Old Guy: Ancient by even Chozo standards, but still a very wise, very kind and patient parental figure for Samus.
• Doting Grandparent: A very benevolent and kindhearted grandfather figure and Parental Substitute for Samus.
• Fat and Skinny: He's noticeably more bulky than Gray Voice.
• Friend to All Children: He has a soft spot for children of all species, stemming from his own inability to have children. He's even willing to leave negotiations to Gray Voice to go play with a child.
• Heterosexual Life-Partners: With Gray Voice. Though they did raise a child together...
• Godzilla Threshold: Invoked but defied. He initially wanted to destroy Zebes to prevent the Chozo planet from falling into the hands of the Space Pirates, but found that they were coordinating far better than anticipated, forcing him to surrender Zebes and flee. It's later revealed that he and the other Chozo were betrayed by Mother Brain.
• In the Hood: He first appears wearing robes and a hood.
• Killed Offscreen: He's presumed dead in the fall of Zebes, it's possible he was one of the Chozo that were willingly executed by Gray Voice (or killed by the pirates), but it's just as possible he was one of the Chozo that fled the planet when it was attacked.
• Nice Guy: Old Bird was shown to be a gentle, loving old Chozo who strived for peace and prosperity across the galaxy, and he loved Samus as if she was his own daughter.
• Old Master: Of the spiritual variety. He teaches Samus meditation, philosophy, and various sciences.
• Older Than They Look: His name includes the word old, but you were probably thinking something around a century. He's been alive much longer than that.
• Parental Substitute: To Samus.
• The Unreveal: While Gray Voice is implied to be from the Thoha tribe by way of Metroid Dread, it's never touched upon if Old Bird is also from the Thoha tribe or another tribe all together.
• Unwitting Instigator of Doom: Ridley was trailing him when he visited K-2L for fuel, which led to its destruction.
• Well-Intentioned Extremist: He's the one who ordered the creation of the Metroids in the Monthly Magazine Z manga. This may still be true of the games, but the circumstances that lead to their creation were tweaked in Metroid 2 Samus Returns and Metroid Dread.

Gray Voice

"Old Bird!! What do you plan to do by bringing a human child here?"

Debut: Metroid (Manga), Metroid Fusion (Japanese version-only ending)

The other Chozo to serve as Samus' adoptive parent. He was also the one who infused Samus with his own Chozo DNA, implied by Metroid Dread to be that of the Thoha tribe.

---

• All There in the Manual: Like Old Bird, he only appears in still images in the games. You have to read the canon manga to know about him as a person.
• Armchair Military: His mental blocks prevent him from fighting himself, but his experience and intelligence make him an excellent tactician.
• The Atoner: He tries to kill Mother Brain to prevent the Chozo's defective creation from endangering anyone else.
• Break Out the Museum Piece: He uses a centuries old Chozo battle suit to take on Ridley.
• Co-Dragons: With Ridley after joining them, becoming Mother Brain's head tactician.
• Dying Moment of Awesome: He shoots down the pirates pursuing Samus just before Ridley finishes him off.
• Dynamic Entry: He blasts his way into Mother Brain's chamber when he tries to kill her.
• Face Death with Dignity: He spends his last moments calmly reflecting on his adopted daughter.
• Fake Defector: When Zebes falls to the space pirates, he betrays the Chozo and joins them waiting for the right moment to eliminate Mother Brain and Ridley. He helped sell the ruse by allowing Ridley to kill the other Chozo, who had already agreed to it.
• Fantastic Racism: He considers Space Pirates, and Ridley specifically, to be nothing but animals with the barest veneer of sentience.
• Fat and Skinny: He's head and shoulders taller than Old Bird and thin as a rail.
• Foregone Conclusion: Since Mother Brain and Ridley both show up in the games, his attempted assassination was doomed to failure.
• Heroic Willpower: All Chozo had mental blocks that caused excruciating pain if they attempted to commit violence in the Monthly Magazine Z manga. He pushes through it to kill Mother Brain, and then to fight Ridley when he interrupts Grey Voice's execution.
• Heterosexual Life-Partners: With Old Bird, to a lesser extent with Platinum Chest, who basically takes up Old Bird's role after the pirate invasion of Zebes in the prequel manga.
• Impaled with Extreme Prejudice: He's impaled by Ridley's barbed tail.
• In the Hood: The same example as Old Bird, though he pulls it off better.
• Jerk with a Heart of Gold: In comparison to Old Bird, Gray Voice is much more willing to Shoot the Dog without blinking an eye, he's also much less doting to Samus than the elder Chozo is and won't hesitate to criticize her if need be. However, he firmly cares about both the Chozo race and Samus very deeply To the point he gives his life to her so that she may live.
• Kill It with Fire: How Ridley ultimately kills him.
• Made of Iron: He survives being impaled long enough to escape and help Samus.
• Mirror Character: To Raven Beak. Both provided Samus with Chozo DNA, and both are, in a way, parental figures to her due to this. They are also both fairly skilled combatants, even if Grey Voice's mental blocks normally prevented him from personally taking part in combat. They differ drastically in how they affected Samus. Grey Voice gave Samus her Thoha genes, raised her alongside Old Bird like a proper father, and ultimately gave his life defending her. Raven Beak on the other hand, gave Samus her Mawkin genes, had little to nothing to do with raising her, attempted to use her and when she refused to submit to him, he attempted to kill her so he could clone her instead. Raven Beak ultimately loses his life... and everything else to an enraged Samus.
• Old Master: While Old Bird handled the mental aspects, Gray Voice taught Samus combat and tactics.
• Older Than They Look: Centuries old, if he hasn't hit at least a millennium.
• Parental Substitute: To Samus. Perhaps more than Old Bird, as he was the one to donate DNA for her genetic modification. Metroid Dread also implies that he was part of the Thoha Tribe, as Samus is noted to have DNA from both the Thoha and the Mawkin (she got the latter from Raven Beak).
• The Spock: He is far less emotional than Old Bird.
• Unwitting Instigator of Doom: He was one of the key figures in the creation of the Metroids, which would fuel Raven Beak's ambitions for the Mawkin Tribe to rule over the galaxy.
• Well-Intentioned Extremist: In the prequel manga he's willing to exterminate a race of peaceful space butterflies to halt the spread of a deadly plant and save the Zebes ecosystem.

Raven Beak (Major Unmarked Spoilers)

"Hadar... sen olmen." ^TranslationPower... is everything.

^{Click here to see him without his helmet.}

Debut: Metroid: Samus Returns (flashbacks only), Metroid Dread (first in-game appearance)

Voiced by: Dave Rogers Ruiz

The leader of the warrior Mawkin tribe who once helped the Thoha tribe of SR388 seal away the Metroids underground, only to then have his warriors slaughter the tribesmen, as seen in the Chozo Memories. He returns in the present day on ZDR, armed with his silver Power Suit, waiting for Samus to arrive and investigate the planet for his nefarious agenda. In the Chozo Language, his name is Ashkar Behek.

Due to just how immensely important he is to the overall plot of not just Dread, but the entire franchise up to his official introduction, all spoilers will be fully unmarked!

---

• Abusive Parents: Though he considers himself to be Samus' father due to donating his genes to her, he only sees Samus as a weapon for his goals, and won't hesitate to kill her so he can get his Metroid army.
• Abusive Precursors: Unlike the Benevolent Precursors status of the rest of the Chozo thus far, Raven Beak distinctly is a warmongering sociopath who wants to clone the Metroids to conquer the galaxy, making him this by default.
• The Ace: Quite possibly the most powerful warrior Chozo in history and almost certainly the strongest of the Mawkin. Quiet Robe states that he possesses "superior physical prowess and intelligence" and he demonstrates it not only by besting the already top-tier Samus in their initial fight and one of the seemingly unstoppable E.M.M.I, but also by manipulating her from behind the scenes. He is also able to imitate ADAM's text-to-speech generated voice in a perfect and non-native English and operate the Chozo's already advanced technology. He is only surpassed in intelligence by Quiet Robe- whose expertise is needed for his ultimate plan.
• Always Someone Better: He is one of the very few characters able to actually best Samus in combat, utterly curb-stomping her in their first battle, and the only reason he let her live was due to Samus inadvertently awakening her Metroid powers. Adam outright tells Samus that even at her full power with all of her abilities, she wouldn't stand a chance against him, a statement that is proven true in their second battle as despite Samus faring much better, Raven Beak still manages to gain the upper hand and the only reason he lost was due to Samus using her Metroid powers to drain him, giving her a massive power boost and weakening him enough for an X Parasite to mutate him into a form weak enough for Samus to finish off. This makes sense when it's revealed that Samus inherited his genes.
• Ambition Is Evil: He was once a great warrior, but his lust for power led him to turn against those of his own species that attempted to stop his plans to clone a Metroid army to conquer the galaxy.
• Archnemesis Dad: It is revealed that he donated his Chozo DNA to Samus, making him a biological father to her. However, he only sees her as a weapon for his goals and won't hesitate to kill her so he can have his Metroid army. And Samus is more than willing to kill him.
• Arm Cannon: Raven Beak's Power Suit, like Samus', is equipped with an energy cannon on his right arm that can fire a wide array of projectiles. However, a flashback to Samus' childhood shows it wasn't always equipped to his Power Suit.
• Arrogant Kung-Fu Guy: Raven Beak is incredibly strong, but also very arrogant, believing himself to be above all others. His mantra of "Power is everything" leads him to believe that his power gives him the right to rule the galaxy.
• Asshole Victim: After all the crimes he committed, indirectly causing the events of the entire series, and ruthlessly pursuing his ambitions; up to betraying his own kind and seeking to weaponize the Metroid species to take over the galaxy, presenting himself as The Chessmaster all the while by manipulating Samus's growth throughout Dread to acquire her DNA... it's only fitting Raven Beak meets his end when his pride gets the better of him and his carefully calculated plans fall apart when Samus manages to overpower him through her Metroid form. She also drains him of his lifeforce... that which, in the process, that leaves him vulnerable to the newly freed X that he callously abandoned his kinsmen to while saving his own skin. It wastes no time painfully assimilating Raven Beak into itself, all while he's aware of what's happening to him as Samus watches before obliterating his X-form doppelganger completely.
• Attack Its Weak Point: While it doesn't apply to his boss fight, the crack on his helmet from his initial fight with Samus is still there — and since Metroids siphon energy from the head, Samus just needs to reach that crack with her free hand. She can't overpower Raven Beak to do this at first, but once her Metroid DNA fully awakens after the boss fight, she latches on and doesn't let go.
• Badass Armfold: He'll sometimes make this pose. It even serves as one of his attacks in his boss fight.
• Badass Cape: He shown to wear a long cape, and it's one of the most formidable foes Samus has ever faced. During the final boss fight, his cape gets destroyed by a point-blank blast from Samus.
• Bad Boss: His rule over ZDR, as shown in the Chozo Archives, depicts him as a brutal dictator who abuses Kraid in captivity and feeds Chozo tribesmen (implied to be Mawkin dissenters) to Drogyga. Even the picture showcasing the discovery of an X Parasite Chozo soldier depicts Raven Beak to be unmoved by this predicament, as if he saw his soldier's death to be an inconvenience or worse, an opportunity. Given he's the Sole Survivor of the Mawkin in the present, it's even subtly implied that he abandoned his troops to the X while he holed up in Itorash.
• Bald of Evil: After being beaten by Samus and his armor getting destroyed beyond repair, he distinctly lacks any feathers on his body and instead has a skull-white head.
• Battle Aura: Raven Beak's armor is equipped with the Lightning Armor Aeion ability, causing it to glow with a magenta aura that deflects Samus' shots. He has a golden version that makes him immune to Samus' beam and missile attacks.
• Beam Spam: One of his attacks in the second phase of the boss fight is a Beam Burst barrage from his Arm Cannon.
• BFG: Wields an arm cannon that's roughly about as large as Samus is.
• Big Bad: The main antagonist of Metroid Dread, responsible for trapping Samus deep underground of ZDR and corrupting the E.M.M.I. robots to hunt her down. It's revealed that he's the one who sent the transmission video to lure Samus in, and his ultimate plan is to extract the Metroid DNA from Samus' body so he can build an army of cloned Metroids to take over the galaxy.
• Big Bad Ensemble: With the X Parasites in Dread. While Raven Beak is the more personal threat of the two, the X are as every bit as dangerous as they break out and both of them need to be dealt with to save the galaxy.
• Big "NO!": Gives off something that sounds like this when Samus jams her fingers into the side of his face and starts draining his energy using her Metroid DNA.
• Bilingual Dialogue: Even though Raven Beak is the chief of the supremacist Mawkin tribe who almost certainly looks down on the rest of the galaxy, he is fully fluent in English, which he utilizes to impersonate ADAM and guide Samus throughout the course of Dread.
• Bond Villain Stupidity: He spares Samus after effortlessly besting her at the start of the game when her Metroid powers begin to awaken. While this was to observe her transformation and try to manipulate her to her side, it was far riskier to do that rather than just going with his Plan-B of creating clones from her DNA who would be mindlessly subservient to him.
• Book Ends: It's only fair that the final adversary of Samus's Myth Arc is a member of the Chozo, the same race that taught her everything she knows.
• Bring It: One of his attacks is to taunt Samus with this gesture, complete with a Badass Armfold. If she takes him up on the offer and tries to hit him with a Melee Counter, it leads into an extended sequence with two Counters, but a much longer timeframe to fill him up with missiles than usual.
• Brutal Bird of Prey: Without his armor, he looks like a giant humanoid eagle and he's the main villain of Dread.
• …But He Sounds Handsome: A non-comical example. While impersonating ADAM, he will sometimes speak highly of himself, especially later in the game when ADAM starts acting more and more out of character.
• The Caligula: While he is a very competent warrior and schemer, he wasn't a great leader for the Mawkin tribe, nor would his plans for conquest have been good for galactic civilization, being a megalomaniacal warlord that values power above all else, even if that power comes from killing a countless number of beings. The Chozo Archives imply that he kept his tribe loyal to him primarily through executing dissenters. When he got the idea for galactic conquest, he planned to do so using a notoriously dangerous bio-weapon that has been shown to be incredibly difficult to control without a strong psychic presence and which has killed several of his tribespeople while trying to contain them. By the time of Dread, his actions resulted in him being an aspiring galactic conqueror in charge of a dead civilization, only having an army of robots and bio-weapons at his disposal while not being torn up in the slightest about being the last Mawkin alive.
• Call-Back: His moveset as a boss in Dread includes not only abilities Samus can use in that game, but also two Aeion powers from Samus Returns (the Beam Burst and Lightning Armor).
• Can't Kill You, Still Need You: After slaughtering the Thoha tribe, he spared Quiet Robe as he was the only one who could control the Metroid. Likewise, after Samus accidentally awakens her Metroid powers in their first fight, Raven Beak decides to spare her and lets her run around ZDR to test her strength.
• Character Catchphrase: "Hadar sen olmen", Chozo for "Power is everything". He says it when he first fights Samus in Artaria, he says it again when he's about to kill her in Itorash and his X Parasite form says it repeatedly as a Madness Mantra. It's even embroidered on his clothes in Chozo script.
• Clipped-Wing Angel: After he's defeated by Samus, an X Parasite strikes from behind and absorbs the evil Chozo, mutating him into a mishmash of all the bosses that Samus had faced on ZDR, including Kraid. This monstrosity, however, is slow and it only takes one carefully aimed Hyper Beam from Metroid Samus to destroy him for good.
• Contrasting Sequel Antagonist: To much of the series' other main antagonists.
  • Most of them such as the Queen Metroid and SA-X are just instinct-driven monsters with only vaguely implied intelligence.
  • Mother Brain is a megalomaniacal mastermind with mostly simple-minded beasts working under her through mental manipulation rather than brute force. This is best seen with Kraid's status under her versus his status under Raven Beak.
  • Dark Samus, while about as cruel, had only greed for Phazon and Omnicidal Maniac goals.
  • Alarmingly, the one that Raven has the most in common with is Ridley, in that they are both violent, narcissistic and destructive commanders with no redeeming qualities to speak of; and even then, while Ridley's monstrous personality is only implied in certain sources like the Metroid manga and Super Smash Bros. Ultimate, Raven's depravity is made front and center from the get-go. To top it off, the other antagonists were but Arc Villains at the very least. Raven Beak singlehandedly kickstarted the entire series' Myth Arc, indirectly causing all of the abovementioned's own schemes or conceptions. In contrast, Ridley is consistently The Dragon to the true Big Bad, in spite of his rivalry with Samus. It's telling when, according to sources such as the Manga, Ridley at least had a measure of camaraderie with his men despite being a Bad Boss and seemingly had an actual friendship with Kraid, while Raven has loyalty to absolutely no one but himself and seemingly left his men to fend for themselves during the X outbreak. Their relationships to Samus are are also polar opposite, with Ridley having orphaned Samus by killing her human parents, while Raven Beak considers her his daughter due to him donating his DNA to her.
• Control Freak: He doesn't tolerate disobedience at all, to the point that he drops his ADAM impersonation and commands Samus to join him when she shows signs of resistance. In the Chozo Archives, he's seen overseeing the execution of Chozo prisoners implied to be Mawkin dissenters and his ultimate plan is to bring order to the galaxy.
• Create Your Own Hero: Raven Beak is revealed to have been another DNA donor for Samus — even believing her to be his daughter because of this. That means he is responsible for her development of combat capabilities and pretty much made the heroine that would eventually bring him down.
• Creepy Crows: He goes by "Raven Beak" and is one of the most terrible villains Samus has ever faced. Notably, his Chozo head looks different from the other Chozo in the franchise, causing him to resemble a raven, and during his boss fight he sprouts black-feathered wings.
• Curb-Stomp Battle:
  • His first battle ends with Samus utterly defeated as her weapons fail to scratch his armor. The only wound he suffers is a blast to the face from a missile and the only reason he doesn't kill Samus right then and there is because of her awakening her Metroid powers, convincing him to spare her life and test her strength.
  • That wrecked E.M.M.I. Samus encounters in the beginning of the game? A gallery picture reveals that that was Raven Beak's doing, which shows just how powerful he is considering that Samus, even with her full arsenal, can't destroy them without the use of the Omega Beam.
• Curb Stomp Cushion: Though Samus fares much better against Raven Beak in their second battle, he still manages to gain the upper hand in their fight. The only reason he lost is due to Samus using her Metroid powers to drain him, weakening him enough for an X Parasite to mutate him into a form weak enough for Samus to finish off.
• Dark Is Evil: His power suit has many dark colors to it, he fires blasts of dark energy and he's even got it right in his name: Raven Beak. Fittingly, he has a black beak and feathers under his armor.
• Deader than Dead: Samus destroys both his X-infected physical form and the X Parasite containing his genetic material and memories at the conclusion of Dread, ensuring that no trace of him will come back to threaten the galaxy in the future.
• Death by Irony: Raven Beak wanted to use the Metroids as bioweapons for galactic domination. He ultimately meets his end at the hands of the most powerful Metroid, Samus Aran herself.
  • Also heavily ironic that his actual killer, an X Parasite, was only able to do so because HE deliberately set them free as an obstacle to Samus to test her abilities.
• Didn't Need Those Anyway!: During their final battle, Samus manages to shoot one of his wings off. Raven Beak simply rips the other wing off and resumes fighting on foot.
• Early-Bird Cameo: No pun intended, but Samus Returns features Raven Beak in one of the Chozo Memories before his full introduction in Dread. Raven Beak is seen in the last two Memories discussing with the Thoha tribe about the sealed Metroids, only for him to gun down all but Quiet Robe in a surprise attack, with clear ill-intent for the planet that would elaborated on years later in Dread.
• Eaten Alive: His ultimate fate: As he stumbles towards Samus in Itorash's impact site, an X parasite floats up behind him and absorbs him while he's still alive, creating Raven Beak X.
• Establishing Character Moment:
  • He is first introduced in the Chozo Memories of Samus Returns, and his first action is murdering the Thoha tribe in a surprise attack. This instantly tells players that he is not a benevolent Chozo and his unexplained agenda on SR388 will have greater implications in the future.
  • In his proper debut in Dread, Raven Beak quickly establishes himself as a powerful warrior who is Samus' superior in almost every way, easily defeating her with only a crack on his helmet caused by a Super Missile. During this first fight, he shows off a few moves that he will use against Samus in their final fight onboard the Itorash.
• Evil Cannot Comprehend Good: Power is everything to him, and thus he cannot understand anything beyond that parameter. He believes that because Samus has his DNA from a genetic infusion, that makes him her father and therefore he owns her. He expects Samus to join him because of the potential power they would have over the galaxy, never once thinking that Samus would disobey thanks to her moral upbringing. This failure to understand Samus ends up being his downfall.
• Evil Counterpart:
  • Raven Beak has all of Samus' weapons and abilities, and the skill to match, but none of Samus' morality or humanity. Also doubles as a Spear Counterpart. He also serves as this to Gray Voice as he was an additional genetic donor to Samus during her Chozo blood transfusion. But whereas Gray Voice sacrificed himself to save his adopted daughter from Mother Brain, Raven Beak sees Samus as nothing more than a tool to carry out his plans of galactic conquest.
  • He is also one to Adam, another father figure to Samus. Adam was strict, but never thought of Samus as a tool and was disgusted and horrified by the Galactic Federation's attempts to revive the Metroids as a bioweapon. As such, it's no wonder that Samus is furious when it's revealed that Raven Beak's been impersonating him the whole game.
• Evil Is Bigger: About twice as tall (not counting his helmet) as Samus in her Power Suit who is 6'3 tall according to the Metroid II: Return of Samus manual.
• Evil Gloating: After overpowering Samus in their second fight, Raven Beak grabs her in a Neck Lift and starts boasting about how he'll be able to clone Samus herself and turn her into an army to rule the galaxy, giving Samus enough time for her Metroid DNA to take over and drain him of his life energy.
• Evil Is Not a Toy: Owing to his arrogance, Raven Beak believes he can harness and weaponize Metroids and X Parasites, only for it to backfire on him.
  • He tries manipulating Samus into getting stronger to use her Metroid DNA. Though he overpowers her again after their second fight — even telling her he doesn't need her anymore — Samus transforms and turns the tables against him with her newfound power.
  • Though he did manage to contain the X infestation on ZDR that was killing his Mawkin, Raven Beak purposefully releases them on the planet to test Samus' strength further. Shortly after his ship crashes after their second fight, Raven Beak gets infected by a X — the same fate he was carefully avoiding.
• Evil Is Petty: He not only killed Quiet Robe’s people and made a mural of the event (showing how proud he is of the massacre), but he has Quiet Robe stationed right next to said mural, for no real reason other than to rub the deaths of Quiet Robe’s people in his face.
• Evil Overlord: He's a militant Chozo dictator clad in silver and black armor with ambitions for galactic conquest and a huge ego to go with them. Not only has he committed genocide against the Thoha tribe for going against his plans to use the Metroids for conquest, he's just as oppressive to his fellow Mawkin. The Chozo Archives show him carrying out executions on other Mawkin soldiers by feeding them to a Drogyga, with the implication being that these Mawkin were dissenting against his rule and were being executed to quell any further opposition to his rule. When several of his warriors died trying to seal the Metroids on SR388, the only thing he saw in the Metroids was an asset to help him rise to power and not a threat to galactic civilization like the rest of his species wisely feared. When an X Parasite snuck onboard the Mawkin ships and came to ZDR following the Thoha genocide, his only response to his tribe getting infected was to quarantine them in Elun and leave them to die. Even though he's the only member of his tribe left by the time of Dread, Raven Beak still kept his desire to rule through the power of Metroids, filling the gaps in his army with robotic imitations of his former soldiers and bioweapon beasts.
• Evil Sounds Deep: His voice is a growling hiss with his helmet on and even his agonized screams as an X Parasite kills and assimilates him have a very low octave.
• Eye Scream: Possibly. When Samus jams her fingers into his face and drains his energy with her Metroid DNA, one of the fingers appears to go into his eye. His last appearance only shows the other side of his face, so we never get a look at the aftermath.
• Fallen Hero: He was once one of the Chozo’s greatest warriors, until his lust for power drove him to slaughter the Thoha tribe, intending to clone a Metroid army with which to conquer the galaxy.
• Fascist, but Inefficient: He is an excellent example of how being the Worlds Greatest Warrior doesn't translate to being a competent leader. While many forces who've tried to weaponize Metroids failed to realize that they are really difficult to control (and the AI they create to control them end up becoming just as megalomaniacal before turning on them), Raven Beak was at least smart enough not to kill all of the Thoha tribe: he spared Quiet Robe and conscripted him as a scientist so he could control the Metroids. However, after the massacre of SR388, an X Parasite snuck aboard the Mawkin ships and infested the rest of the tribe (ironic, since such a scenario was what Metroids were created for), and his only reaction was to leave them in quarantine to die (and while he was dealing with that, the rest of the Metroids were exterminated by Samus). Even before the X outbreak, the Chozo Archives show that his rule over the Mawkin was generally oppressive, as he often fed dissenters to Drogyga to ensure his tribe's blind loyalty. Once Samus comes to ZDR with a Metroid DNA infusion, Raven Beak has Quiet Robe killed right after Quiet Robe tells Samus about what's going on, banking on a plan to get Samus to fight by his side by using his status as one of her Chozo gene donors as leverage, and if that fails, making an army of Metroid Samus clones that are much more cultishly devoted to him. However, not only did Raven Beak give Samus countless reasons to hate him, he also ended up giving her the means to destroy him while trying to win her over.
• Fatal Flaw: Fittingly for a Proud Warrior Race Guy, Pride. While undeniably dangerous, Raven Beak's arrogance leads him to overestimate his abilities and underestimate his opponents. Rather than kill Samus and extract the Metroid DNA like he originally planned, he decides to let Samus run around ZDR to test her strength after she unwittingly awakens her Metroid powers, never once considering the possibility that Samus may become strong enough to actually defeat him. And sure enough, this leads to his downfall as Samus uses her Metroid powers to drain him, weakening him enough for an X Parasite to mutate him into a form Samus could defeat once and for all.
• Faux Affably Evil: While pretending to be ADAM, Raven Beak feigns kindness and concern for Samus just so she can unlock her true potential, and then tempts her to join his cause of bringing order to the galaxy. When Samus rejects him, Raven Beak drops his act and tries to kill her in a brutal manner.
• Final Boss: Of Metroid Dread.
• Final-Exam Boss: A given since the villain has the full power of Chozo technology at his disposal. Each of Raven Beak's moves can be countered or avoided by almost every weapon or ability in Samus' arsenal. The player must make very effective uses of Storm Missiles, Power Bombs, Super Missiles and Flash Shifts to win the battle.
• Final Solution: He had the entire Thoha tribe wiped out to prevent them from destroying SR388 and thus the Metroids, literally sparing only one Thoha Chozo, Quiet Robe, because that's all he needed to enact his plan to control the Metroids.
• Flash Step: He is capable of using the Flash Shift Aeion ability to rapidly close the distance between himself and Samus. He can also Shinespark at will during the third phase of the boss fight.
• Foil: To Samus. Besides the obvious similarities (i.e. Power Suit, Arm Cannon, Aeion Abilities), his treatment of his daughter is a twisted reflection of how Samus treated the baby Metroid. While Samus spared the baby out of selfless mercy, Raven Beak spared Samus so he could selfishly use her power. As a result, when the baby attacked Samus, it came to its senses and eventually saved her life: when Samus attacked Raven Beak, she went through with the deed.
• Galactic Conqueror: What he aspires to be. He plans to capture Samus and extract her Metroid DNA so he realize that dream. It's disturbingly similar to Mother Brain's agenda, almost as if the Chozo computer got this idea from his philosophy.
• Genius Bruiser: In addition to being a powerful warrior that outmatches Samus herself, Raven Beak is also shown to be quite cunning and intelligent by reprogramming the E.M.M.I drones into targeting Samus for her Metroid DNA as well as being a skilled enough linguist to perfectly impersonate ADAM. Quiet Robe himself describes Raven Beak as having "superior physical prowess and intelligence".
• Gone Horribly Right: His ultimate plan is to awaken Samus' Metroid DNA to create his army to conquer the galaxy, sparing her after their initial encounter and allowing her to grow stronger by killing enemies on ZDR. Suffice to say, he succeeded in awakening her dormant powers — only for Samus to become much stronger than him and destroy him for good.
• Greater-Scope Villain: Quiet Robe reveals that Raven Beak is the one ultimately responsible for the Metroid crisis since the first game. Originally, the Thoha tribe of SR388 wanted to destroy the planet after sealing away the Metroids, believing them to be too much of a threat. But Raven Beak desired the Metroids for their power and thus slaughtered the Thoha tribe, only sparing Quiet Robe for his bioweapon project. As a result, the Metroids were left to be discovered by the Galactic Federation and later the Space Pirates, leading to the events of the franchise.
• Heads I Win, Tails You Lose: Just when it seems like he's finished in the final battle, he parries Samus and Flash Shifts her into a chokehold just like their first fight. Despite all the damage she's inflicted and the massive fight they just underwent, Samus still isn't powerful enough on her own to beat him. The thing is, he didn't predict her suddenly flipping out and fully converting into a Metroid just to finally kill him.
• Hidden Depths: Though he primarily speaks his own language during his on-screen appearances, the fact that he was able to impersonate Adam for much of the game indicates that he's actually fairly fluent in English despite likely viewing the human race as inferior considering his supremacist mindset.
• Hoist by His Own Petard:
  • His entire endgame is to have Samus fully awaken her Metroid DNA and wholly manifest the Metroid power to siphon energy, assured that even if Samus accrues all the power there is to be found on ZDR, she won't be able to beat him if she defies him. And he would have been right about that, were it not for the fact that, in Samus, that very Metroid power he cultivated manifested on a scale so unbelievably strong that even he was helpless against it.
  • In order to pressure Samus into cultivating her Metroid powers, he released the X Parasites from their quarantine in Elun, letting them overrun the planet while he sits confortably in his ship waiting for Samus. As soon as his ship crashes, an X Parasite infects him.
  • Choosing to leave SR388 intact in order to use the Metroids as a bioweapon inadvertently spared the X Parasites — a consequence that would eventually lead to the total extinction of his tribe, when one of his scouts searching for the former got infected by the latter and returned to ZDR.
• Homing Projectile: One of his attacks is to fire a slow-moving orb of dark energy that will follow Samus around the room until it's either destroyed or it hits her. It bears a distinct resemblance to the Darkburst from Prime 2.
• Implacable Man: Raven Beak demonstrates how tough Chozo technology is with him shrugging off almost everything Samus throws at him. Her Melee Counter is able to push him back and it takes a super missile to damage his armor. And all that does is make him angry.
• Impostor Forgot One Detail: It's revealed that he's been impersonating the Adam AI since Samus lost contact. However, Raven Beak constantly refers to Samus by her full name rather than the nickname "Lady". At the climax of the game, his cover is blown completely when he orders Samus to surrender her Metroid powers, something the real Adam would never do.
• I Need You Stronger: It's revealed that his entire plan was based around "helping" Samus awaken her Metroid DNA so that she would fully evolve into a humanoid Metroid. After he succeeds, he offers a chance to work with him to "bring order" to the galaxy, but when Samus refuses, he reveals that he can just kill and clone her to make an entire army of the most powerful Metroid ever.
• "It" Is Dehumanizing: Vol. 7 of the "Metroid Dread Report" uses the word "it" to describe the warrior, no doubt to make the character feel more mysterious and intimidating. Subverted in the actual game, where it's revealed to be a male Chozo named Raven Beak.
• It's All About Me: For all his claims of wanting to bring order to the galaxy, it’s clear that Raven Beak cares for nothing but satisfying his ambitions. Even his fellow Mawkin Chozo are not exempt as he would feed them to Drogyga, and basically abandoned them in Elun to die or get infected by the X so that he could save his own skin.
• The Juggernaut: Throughout the game, ADAM repeatedly warns Samus that Raven Beak is incredibly powerful and she likely wouldn't stand a chance against him, with "ADAM" later turning out to be Raven Beak hyping himself up, and it turns out that he wasn't exaggerating much, if at all. Throughout the game, he trounces Samus without even breaking a sweat in his first appearance, mangles one of the E.M.M.I. robots that were made out of the toughest materials in the galaxy and were too durable for Samus to even scratch so badly that it can't even chase her properly, reacts to Samus blowing one of his wings off by casually ripping the other one off and keeping the fight going, takes hundreds of shots and missiles during his boss fight, and ends it by revealing he may have actually been holding back the entire time and then literally strangles Samus to death. The only thing that brings him down is Samus being revived by her Metroid DNA and draining him of energy while gouging one of his eyes out.
• Karmic Death: On two fronts. He is not only killed by an X Parasite, who he condemned his own people to certain death against, but the very Metroid powers he goaded Samus into awakening and intended to exploit not only allow Samus to gain the upper hand in their fight, but allows her to finish him off for good.
• Kick the Dog:
  • His appearance in Samus Returns has him inexplicably killing fellow Chozo as is, but then we find out why in Dread: he was simply annoyed that the more rational and reasonable Thoha tribe had interfered with his plans for weaponizing Metroids. So he killed all of them but Quiet Robe so they couldn't interfere in his plans, and forced said survivor to work on his weapons and machinations against their consent.
  • A Chozo Archives image even shows that he straight up subjected even his dissenting fellow tribe members to a Shameful Strip before feeding them to a Drogyga pit, highlighting that unlike Samus and the other Chozo, he holds absolutely no bonds of racial kinship and simply would kill everyone if he was to stand on top at the end.
  • As if performing a complete genocide of the Thoha and enslaving their Sole Survivor wasn't bad enough, he went so far as to have a mural depicting and celebrating the atrocity created outside the lab where Quiet Robe would work, hanging a constant reminder of what happened to his people over his head.
• Large and in Charge: Raven Beak is much larger than the lesser Chozo soldiers, being roughly twice as tall (not counting his helmet) as Samus in her Power Suit, while the soldiers are just One Head Taller. Considering Samus is officially 6'3 tall in her Power Suit according to the Metroid II: Return of Samus manual, that would make him somewhere not far south of 13 to 14 feet tall.
• Lightning Bruiser: He's fast, strong, and durable, with Samus being on the back foot during their first encounter. Even during their rematch, he's more than powerful enough to shred through her armor's defences and almost strangles her to death.
• Luke, I Am Your Father: Raven Beak reveals to Samus that he was one of the Chozo who donated their genes to her on Zebes, specifically the Mawkin genes. He even calls Samus his daughter.
• Made of Iron: Even leaving aside his Aeion armor, which can shield him from tens of missiles and only stops regenerating after a particularly strong hit, Raven Beak is insanely durable. He takes dozens of beam and missile hits, gets one of his wings blasted off and tears out the other one himself and still holds his own enough to Neck Lift Samus into submission. Samus then proceeds to drain him full-on with her awakened Metroid powers — and Itorash along with it, causing the fortress to crash from miles up in the sky — and Raven Beak is still able to walk, if only just. It's only getting absorbed alive by an X parasite that finishes him off for good.
• Major Injury Underreaction: His response to getting one of his wings shot off by Samus? Rip off the other as there was no point in it any more.
• Make an Example of Them: The reason why the Mawkin tribe was completely loyal to Raven Beak is because he fed all Mawkin dissenters to Drogyga, as revealed in the Chozo Archives.
• Meaningful Name:
  • Ravens are often associated as symbols of death and ill omen. True to form, Raven Beak’s presence on ZDR casts an eerie sense of foreboding throughout Dread’s story, beginning with his absolute curb-stomping of Samus in the game’s intro. Then there is his being indirectly responsible for causing the Metroid crisis that has caused so much death and destruction in the galaxy, including the deaths of the Hatchling as well as Adam Malkovich and the 7th Platoon ^note  Except for Anthony Higgs. . Finally, his face when unmasked looks very similar to that of a raven’s head.
  • The word "raven" can refer to an object displaying a dark, glossy appearance. For Raven Beak, this is literally the case, as his brief unmasked appearance does feature a dark-ish, possibly cybernetic beak.
• Might Makes Right: Quiet Robe describes Raven Beak as someone who "worships on the altar of power" and viewed the Metroids as a means to conquer the galaxy. As Raven Beak tells Samus:
  Raven Beak: Power is everything.
• Mirror Boss: Raven Beak can use all of Samus's Aeion abilities during the final boss fight (even ones from Samus Returns), plus a version of her Shinespark, as well as some moves of his own.
• Monstrosity Equals Weakness: He's far less potent of a threat after being assimilated by an X Parasite and amalgamated with Kraid, thanks to no longer having his powerful weapons nor his Chozo physique and also due to Samus having the Hyper Beam to finish him off.
• My Species Doth Protest Too Much: What makes Raven Beak truly stand out from the rest of the Chozo is how much of an antithesis he is to them and everything they stood for. He chooses war over peace, conquers worlds instead of sharing wisdom and values power over legacy.
• Narcissist: In addition to being a ruthless warlord bent on galactic conquest, Raven Beak is also shown to be an absolute egomaniac. To wit, he considers himself to be Samus’ father just because he was one of her genetic donors when she was infused with Chozo blood. This in spite of the fact that her actual adoptive parents, Old Bird and Gray Voice, are clearly shown in the flashback scene of her blood transfusion. The fact that he believed Samus would end up serving him because of this tenuous claim of parentage despite her knowing of all of his atrocities only highlights what a complete narcissist Raven Beak is. And his admiration for Samus's abilities is tinged with the typical narcissistic parent's view of their children as extensions of themself, complete with reacting violently when Samus asserts herself against his authority. More subtly, he also speaks incredibly highly of himself while impersonating Adam.
• Near-Villain Victory: Despite Samus becoming stronger and acquiring new powers — on top of abilities discovered by tapping into her Metroid DNA — Raven Beak still overpowers her in the final battle. Only after her power is fully awakened, right before she almost dies, is Samus able to turn the tables on him.
• Neck Lift: Does this to Samus twice, to show he is overpowering her.
• Nice Job Fixing It, Villain: The very plan he hoped to enact against Samus winds up being the cause of his defeat. Raven Beak tricking Samus into releasing the X from Elun was implied to be an attempt to make Samus' Metroid DNA grow stronger. The X then possess literally everything organic, living or dead, and since Raven Beak is vulnerable once he makes planetfall back on ZDR, he winds up possessed himself. In the end, the only thing he really accomplished was to make Samus more powerful than ever.
• No-Sell: Halfway through the first phase of his boss battle, his Lightning Armor turns gold and protects him from Samus' munitions, up to and including Power Bombs. The operating word is 'munitions;' progress can be made by melee countering him to temporarily deactivate it.
• Not So Stoic: Like Samus, he is a stoic warrior who isn’t easily flappable. That changes, however, when Samus overpowers him while transforming into a true Metroid and drains his energy, causing him to react with a mixture of fear and anger as he futilely attempts to throw her off of him.
• Not-So-Well-Intentioned Extremist: He attempts to convince Samus that he is trying to bring order to the galaxy...by mass-producing an army of Metroids much like the Space Pirates and the corrupt faction of the Galactic Federation Army tried to do, and massacring his own people in the process. Samus makes it clear she does not buy his spiel for a second, especially since it's the exact same plan Mother Brain described in the manga.
• Oh, Crap!: The one time Raven Beak is actually caught off-guard and shocked is when Samus forcibly converts her body into a full Metroid Suit form, gaining enough strength to finally grab his face for her Energy Absorption. He's left screaming, thrashing and firing off his beam cannon wildly in a literally-blind panic before she finally pins him to the ground.
• Old Soldier: As one of the last surviving Chozo, he's at least centuries if not millennia old, but age doesn't seem to have slowed him down one bit in combat.
• One-Winged Angel: In his second phase of his boss fight, he sprouts two bird-like wings and begins flying in the air, becoming harder to hit and evade. Samus manages to blast one of his wings at the end of the second phase, which ironically makes him literally one-winged... until he rips out the other wing and proceeds to fight Samus on foot.
• Orcus on His Throne: Zigzagged. In the prologue Raven Beak actually goes to confront Samus himself the moment she touches down in his base but after defeating her in their initial battle, he subsequently spends the majority of the game monitoring her progress from behind the scenes. In particular, it's revealed that he's been impersonating Adam since they lost contact. This may be justified in that he has kept the X-infected Mawkin quarantined on Elun while he stays aboard his ship and thus avoids having to leave his base unless absolutely necessary in case the X manage to escape containment. It also makes sense that he wouldn't be in any hurry to kill Samus, since he wants to observe Samus and see how her Metroid powers would manifest themselves.
• Parental Abandonment: Despite being one of Samus' adoptive fathers, he played absolutely zero role in raising her outside of donating his genes. This makes his insistence that she is his "daughter" and therefore must obey him seem even more narcissistic, as unlike Gray Voice, Raven Beak has done nothing to earn Samus' love or respect whatsoever.
• The Peter Principle: He is undoubtedly one of the greatest warriors to ever live, being one of the very few that can claim to have bested Samus Aran in combat. However, when Rank Scales with Asskicking, he proves to be a woefully incompetent leader who primarily rules through fear and eventually gets all of his people killed in one fell swoop as a result of his lust for power.
• Powered Armor: Raven Beak's armor is clearly of a similar make and design as Samus's Power Suit — after all, the Chozo were the ones who originally used them. His armor even has a modular Arm Cannon with a variety of projectiles that far surpass Samus' in power.
• Power Gives You Wings: Befitting of his status as the most powerful warrior in the Chozo's ranks, he is uniquely the only Chozo depicted that actually has usable wings on his back that gives him the power of Flight during his boss battle.
• Power of the Sun: One of his attacks in his boss fight has him summon a large sun that will release shockwaves all over the room. The sun can be destroyed for ammo. It bears a resemblance to the Sunburst from Prime 2.
• Ramming Always Works: The second phase of his battle (after he sprouts wings) includes attacks where he tries to ram Samus, either horizontally or from above. In the third phase this is replaced by a version of Samus's Shinespark technique (which he can use without charging up first).
• Rasputinian Death: During his final battle with Samus he takes a ridiculous amount of punishment before expiring. He loses both his wings, Samus jams her fingers into his skull and initiates a Metroid energy drain so powerful that it knocks out the entire ship they're fighting on, and then the ship crashes into the ground and explodes with him still inside. After all that, while exhausted, he's still somehow standing. A moment later he's infected by an X Parasite, painfully mutated into a gigantic abomination and finally destroyed by Samus' Hyper Beam. She then vaporizes the parasite holding his DNA, making sure he'll never come back.
• Red and Black and Evil All Over: He wears silver and black Power Armor with red accents, a dark arm cannon with red light pouring out of its sides and a dark cape with a red inside, and he happens to be a villain.
• Red Eyes, Take Warning: He has glowing red eyes and is a dangerous foe. Even without a helmet, his eyes naturally glow red.
• Satanic Archetype: If Ridley represents the classic Devil, then Raven Beak represents Lucifer. He is possibly the greatest Chozo warrior in history and certainly the most prideful of them all. He wears shiny silver and black armor and possesses two dark feathered wings, giving him the impression of an evil-looking angel and he tempts Samus to join him through the guise of ADAM, her dear friend. When Samus defeats him, he loses his wings and his personal ship plummets down from the sky to the ground, where an X Parasite absorbs him and transforms him into the hideous monster he was on the inside.
• Sean Connery Is About to Shoot You: His official artwork has him aiming a partially-charged Arm Cannon at the viewer.
• Smug Super: His arrogance isn’t completely unfounded as every time Samus faced him, has had him holding the upper hand in the battle and his abilities are far above hers. If Samus hadn’t transformed into a Metroid, he would’ve killed her in the final fight.
• The Sociopath: Raven Beak has all the traits of a classic sociopath. He has no empathy for anyone but himself, ruthlessly slaughtering his fellow Chozo, he will manipulate others with no hesitation, and he is extremely arrogant.
• Sole Survivor: As it's revealed by Quiet Robe, Raven Beak is the last surviving 'pure' Mawkin (excluding Samus who is only genetically-related), as the rest of his tribe were wiped out and assimilated by X. Though, given his plans and being The Sociopath, he's not too broken up in being the last of his tribe. Considering we never see any other living Chozo in the present day and Quiet Robe doesn't live past his introduction scene, he may actually be the Last of His Kind for the entire Chozo species by the end of the game. If so, his death would cement the Chozo's extinction, with their DNA only continuing to persevere through Samus.
• Strong and Skilled: Fittingly, Raven Beak does not only have an extreme arsenal of weaponry at his disposal, he's also an incredibly skilled warrior who knows just how to use his abilities to his advantage, which on top of his overwhelming strength, makes him an incredibly tough warrior to fight.
• Stupid Evil: Killing Quiet Robe for outliving his usefulness was not a smart idea since his plan was to manipulate Samus into joining him and he just gave her an additional massive reason to hate him.
• Suspiciously Similar Substitute:
  • Raven Beak is one for Gray Voice, as the Chozo who became Samus's biological father and wears a Power Suit into battle. For bonus points, he turns on Samus and seeks to harness the Metroids, just as Gray Voice claimed to — except, whereas for Gray Voice, it was an act to get Mother Brain's guard down, Raven Beak is putting on a show for no one.
  • He's also one for the deceased Ridley, namely for his boss battle and the fact he earns Samus' full wrath by murdering the Thoha tribe (similar to how Ridley murdered the Chozo of Zebes). His boss fight in particular depicts as a very fast and brutal fighter who could easily destroy Samus if she hadn't mastered her speed reflexes and has a flight phase that is a close imitation to Ridley's aerial combat.
  • His plan for galactic domination and blatant attempt to emotionally manipulate Samus by claiming to be her father echoes Mother Brain from the prequel manga. Considering that the late supercomputer brain was also a Chozo creation, this is not surprising at all.
• Teeth-Clenched Teamwork: In spite of being of the single most openly antagonistic Chozo tribe and very much at odds with the rest, a flashback shows that at some point during Samus' Bio-Augmentation, he was brought in by Old Bird, Gray Voice and the others as a donor for Mawkin genes, in order to give Samus the ultimate physical prowess that can be found within Chozo biology.
• Tin Tyrant: He's the leader of the Mawkin Chozo tribe and wears a full suit of evil looking Power Armor.
• Translation Convention: Referred to in Chozo dialogue as "Ashkar Behek", but in subtitles and English dialogue by the translation "Raven Beak" (even by himself).
• Treacherous Advisor: The ADAM AI who's been guiding you throughout the game is actually Raven Beak, impersonating ADAM ever since he and Samus lost contact in the begining. Raven Beak tricked Samus into cultivating her latent Metroid powers so that instead of simply extracting her DNA to create an army of Metroids, he can turn Samus into the ultimate Metroid and then clone her once he defeated her.
• The Unfettered: Raven Beak will do whatever it takes to achieve his goals; whether that means slaughtering his fellow Chozo or attempting to murder his biological daughter in order to make an army of Samus clones to take over the galaxy.
• Upgrade vs. Prototype Fight: As you might expect from the race that created Samus' iconic Powered Armor, Raven Beak's arsenal is functionally identical to Samus', only with the latest upgrades. And unfortunately for Samus, Older is NOT Better, as Raven Beak has much more skill and experience than she does. It's her Metroid DNA, an ability not born of the Power Suit, that allows her to defeat him.
• Viler New Villain: While prior Metroid villains were, at least partially, merely acting on the species' natures or only showed their worst in side material, Raven Beak is a sociopathic warmonger acting on his own volition. He contrasts his fellow Chozo, and even wiped out the peaceful members of his race for opposing his plans of using Metroids as bioweapons, thus causing entire series' events. He spared Quite Robe but forced them into aiding his plans, killing them right as they bond with Samus. In-game files reveal that he captured and tortured Kraid, executed members of his tribe that questioned him by feeding them to a horrible monster, sealed every other Mawkin away to die from X infestation and spent the whole game manipulating and plotting to kill his "daughter" Samus to enable his galactic conquest. At the end of their battle, Samus erupts in a fit of rage never seen before, possibly in response to the vileness of her enemy.
• Villainous Breakdown: When Samus transforms into a proper Metroid and thrusts her hand into his face to violently absorb his energy, he reacts by fearfully screaming for his life and attempting to shake her off of him to no avail. Any words cannot even be heard, as his screaming is mostly drowned out by Samus and her screams of rage.
• Walking Spoiler: His massacre of the SR388 colonists can only be seen by getting 100% Completion of Samus Returns, and it manages to shed a grim new light on the end of the Thoha tribe. There's also the spoilery aspects of his Evil Plan in Dread, especially his impersonation of ADAM.
• Wave-Motion Gun: Raven Beak's Arm Cannon is outfitted with a gargantuan red laser that leaves tremendous detonations wherever it strikes. During cinematic attacks during his boss fight, he even sweeps it in a sustained fire in a manner akin to a Laser Blade.
• We Can Rule Together: As Samus "fulfills her destiny" by becoming the most powerful Metroid, he offers her a place at his side in bringing order to the galaxy. When she refuses, he is disappointed, but no longer needs her, as he can now clone her to create an army of unstoppable Metroids.
• Winged Humanoid: During the second phase of his fight he reveals he has a pair of fully functional wings, unlike any other modern Chozo, making him look very much like a tengu. The second phase ends with Samus blasting one of them off. Raven Beak doesn’t hesitate or flinch at ripping the other one off himself, since it’s only a hindrance to him now.
• World's Strongest Man: He is the ultimate warrior of the Chozo's strongest tribe, and against Samus —lauded until now time and again as the strongest in the galaxy— at peak condition and the strongest she's ever been, Raven Beak makes incredibly quick work of her with his overwhelming sheer speed, strength and defenses. Even a Super Missile to the face only succeeds in putting a scratch over his eye. And come their rematch, even though Samus actually forces him to go all-out this time and costs him his wings, he still decisively trumps her in a head-on battle. The first E.M.M.I. in the game discovered by Samus that was heavily damaged, made of supposedly the hardest materials in the universe making them Nigh-Invulnerable? Yeah, that was entirely Raven Beak's doing, and he didn't even break a sweat doing it with his bare hands.
• Worthy Opponent: Views the Metroids as such, seeing how they defeated various members of the Mawkin Tribe helping their Thoha counterparts seal them away. It's the reason he wanted an army of them in the Mawkin Tribe's ranks against the advice of the Thoha Tribe.
• Xanatos Gambit: After Samus awakens her Metroid powers during their first battle. Raven Beak spares her and lets her run around ZDR to test her strength. If she survives, he can capture her and clone and army of her. If she dies, he can simply extract the Metroid DNA from her. The only thing he didn't count on was Samus growing strong enough to actually defeat him.
• Xanatos Speed Chess: Raven Beak is quite skilled at changing his plans on the fly in response to unforseen developments. Initially, he wanted to use the Metroids as bioweapons, but when the Metroids were eradicated by Samus, he decides to lure her to ZDR with footage of the X Parasites to extract the Metroid DNA from her and clone an army of Metroids. But when Samus inadvertently awakens her Metroid powers during their fight, Raven Beak spares her and lets her run around ZDR to grow her powers so he can clone her instead.
• You Have Outlived Your Usefulness: After Samus refuses his offer, Raven Beak says that Samus herself is no longer necessary as now he can simply clone her to create an unstoppable army.

Raven Beak X

^{Click here to see the actual X Parasite.}

An X which possesses a weakened Raven Beak and combines his biomass with Kraid, creating a monstrous hulking fusion.

---

• Almighty Idiot: The intelligent Raven Beak is reduced to a gibbering mess as he is fused with Kraid and seemingly other bosses as well, due to the X Parasite copying and mimicking all their attributes and memories. The only thing the abomination is able to coordinate is their hatred of Samus.
• Animalistic Abomination: His X form is a twisted combination of himself, Kraid, and likely more creatures, which has his head inside of Kraid's, can barely so much as crawl forward and drones out Chozo sentences.
• Body Horror: This thing generally looks like Kraid having Raven Beak's head and limbs fused with his brain and jaw, and that's not even getting into the other bosses mixed in with this... thing.
• Book Ends: This boss serves as one for the series up to this point, as it is a combination of the first boss you fight in the series and the final one.
• Clipped-Wing Angel: Despite possessing Kraid's massive size, Raven Beak X is painfully slow — only being able to drag itself along the ground towards Samus. This gives her plenty of time to charge up her Hyper Beam, obliterating the X-Parasite's monstrous visage. Additionally, Samus vaporizes it rather than absorb it.
• The Dog Bites Back: The X, by virtue of possessing Kraid's DNA, has memories of Kraid being abused by the Mawkin tribe and likely memories of the Mawkin Chozo who were forcibly locked away in Elun by Raven Beak. Thus, in a fashion, nearly all of Raven Beak's victims assimilated by X got their revenge on the evil Chozo when the X consumes him at last.
• Deader than Dead: Samus apparently doesn't want any more of Raven Beak in her than she already has, so instead of opting to absorb the X once she's reduced it to its core form, she just continues to blast it with the hyper beam until she completely atomizes it.
• Flower Mouth: Raven Beak X possesses Kraid's head split down the middle to create a four-petaled flower mouth with Raven Beak's head inside. It's implied that either Experiment No. Z-57 or Drogyga was assimilated as well to allow this, since they have similar mouths.
• Fusion Dance: Raven Beak X is an amalgamation of the Chozo warrior Raven Beak and Kraid, possessing the latter's massive bulk and head (as a Flower Mouth) and Raven Beak's dark coloration, feathers, scaly avian limbs, and head (as an inner mouth). There also seem to be subtle aspects of other bosses as well, such as the Flower Mouth belonging to either Experiment No. Z-57 or Drogyga and the vestigal arms of the former.
• Madness Mantra: The only thing it's capable of uttering besides roars is "Samus" and "Hadar sen olmen" (Chozo for "Power is everything") repeatedly, likely the result of the X Parasite trying to emulate Raven Beak's megalomaniacal character.
• Mighty Glacier: Zero-Effort Boss it may be, but if the player doesn't think to hold down the Y button immediately, it can end up getting to Samus and eating her in a single chomp. This means it can survive multiple seconds of continuous Hyper Beam fire, something that nothing else can claim once Samus starts making her way to her ship.
• Monstrosity Equals Weakness: Compared to the very powerful, skilled and humanoid Raven Beak, Raven Beak X is far less of a threat than its former self thanks to no longer having powerful Chozo weaponry nor an agile Chozo physique (since it's essentially Raven Beak's head on Kraid's lumbering body), and the fact that Samus has the Hyper Beam to obliterate it.
• Nested Mouths: Raven Beak's head is concealed inside of Kraid's maw, which rips in half vertically to become a Flower Mouth.
• Purple Is Powerful: The X that infects Raven Beak is distinctly purple, and seeing as how it can take a Hyper Beam to the face for more than a few seconds and can swallow Samus whole should it catch up to her, it's definitely powerful.
• Super-Toughness: This thing survives getting drilled in the face by the Hyper Beam for a good 5 or 10 seconds. That's 5 or 10 seconds longer than literally anything else lasts against said Hyper Beam. This likely comes from having Kraid's DNA, as Kraid's skin was extremely tough and nigh-impenetrable.
• Suspiciously Similar Substitute: To the SA-X's second form. Both are misshapen creatures made up of multiple fused organisms and originally derived from characters wielding Chozo Power Suits, but are also much weaker than their original forms.
• Swallowed Whole: Fail to unleash the Hyper Beam on time, and Raven Beak X will anticlimactically devour Samus.
• The Worf Effect: Despite being an amalgamation of two of Samus's most powerful foes and the Final Boss of the series original arc, Samus defeats it in seconds with a single attack to establish how strong her new Metroid powers have made her.
• Zero-Effort Boss: All the player needs to do is hold down the Y button long enough to defeat Raven Beak X.

Quiet Robe (Major Unmarked Spoilers)

"I am Quiet Robe, a scientist of the Thoha Tribe."

Debut: Metroid: Samus Returns (flashbacks only), Metroid Dread (first in-game appearance)

Voiced by: Stephen Hughes

A prominent Chozo scientist on ZDR who is on friendlier terms with Samus than the others — and is the last survivor of the Thoha tribe of SR388 held captive by Raven Beak. As such, Quiet Robe knows more about the Metroids than anyone else, including their creation and powers. In the Chozo language, his name is Henkin Maradis.

---

• Ambiguous Gender: Unlike Raven Beak, Quiet Robe is not referred to by gendered pronouns. At least, not in the English version; in the Spanish version, Quiet Robe is addressed with the masculine form of nouns such as cientifico and amigo, which would indicate that this Chozo is male. Similarly, in the Japanese version, Adam referring to Quiet Robe as "our Thoha friend" is translated as "that Thoha man".
• And Then John Was a Zombie: Quiet Robe was one of the Chozo researching how to stop the X Parasite, and yet ends up being possessed by one after being killed off by one of the Robot Chozo Soldiers.
• The Atoner: Quiet Robe feels responsible for the whole Metroid crisis, from their creation to the Thoha's failure of destroying them to helping Raven Beak prepare for galactic domination. Quiet Robe thus helps Samus on her journey towards the surface, and tells her about Raven Beak so that she may put an end to the wicked Chozo's schemes.
• Big Damn Heroes: Saves Samus from the purple E.M.M.I-06WB in the nick of time. Likewise, Quiet Robe's X copy arrives to give Samus the Thoha DNA needed to help suppress her Metroid powers just in time to escape ZDR's self-destruction.
• Book Ends: His first and last meeting with Samus mirror each other: he appears from behind her, causing Samus to aim her cannon at him until he salutes her, and helps her move forward before dying with a smile.
• Bootstrapped Leitmotif: A remix of the "Lower Brinstar" theme from Super Metroid plays during Quiet Robe's exposition scene, as well as when the X Parasite copy of Quiet Robe sacrifices itself to Samus. This theme predates Quiet Robe by over two decades and is otherwise unassociated with the Chozo, making it a somewhat unexpected choice of leitmotif for this character.
• Chekhov's Gun: Quiet Robe explains that their specific tribe, the Thoha tribe, were responsible for overseeing Metroid development as they have the uncanny ability to control them, something Raven Beak later remarks as being due to their own unique genetic variance. When Samus fully metamorphosizes into a Metroid, the X who assimilated Quiet Robe makes use of this aspect and feeds itself to Samus, giving her a fresh dose of these genes and taming her Metroid biology, reverting her back to her state prior to transforming.
• Go Out with a Smile: Quiet Robe's last act before sacrificing themself to help Samus stabilize her Metroid DNA is to give her a smile as their physical body dissolves.
• Heroic Willpower: Quiet Robe gets possessed by an X Parasite after being killed by one of the Robot Chozo Soldiers but somehow manages to retain the original's benevolent personality within the copy, unlike every other living being that's been infected, as demonstrated at the very end where the X copy sacrifices itself in order to return Samus to normal so that she can fly her ship out of the the self-destructing planet.
• Hope Spot: They disarm all the E.M.M.I. to ensure Samus can succeed in her mission. Later on, though, she accidentally sets the X free to infect the entire planet, and one of them infects Quiet Robe's corpse and makes them reactivate the E.M.M.I.
• In the Back: Quiet Robe is suddenly shot and killed from behind by a Robot Chozo Soldier after explaining everything about Raven Beak to Samus.
• Mr. Exposition: Quiet Robe explains the backstory and motivations of Raven Beak as well as what occurred on ZDR prior to Samus's arrival.
• Recurring Element:
  • Quiet Robe plays a very similar role to U-Mos from Metroid Prime 2: Echoes, being the sole surviving elder of an alien race who gives Samus an exposition dump in the middle of a temple area and a last-ditch mission of critical importance. Unfortunately, Quiet Robe doesn't make it out alive like the Luminoth counterpart does. Fitting, as the Luminoth were similar to the Chozo.
  • The similarities between Quiet Robe and Madeline Bergman from Other M can't be ignored either, both being visionary scientists who are the only sane survivors and regret ever making their most powerful creations. Unlike Madeline, who lived through the entire game and even testified against her corrupt peers, Quiet Robe is killed by a Robot Chozo Solider before they can help Samus further.
• Reluctant Mad Scientist: Quiet Robe was coerced by Raven Beak into working on his Metroid bioweapon project after the latter massacred the Thoha tribe.
• Sole Survivor: Of the Thoha tribe of SR388. Quiet Robe was only spared by Raven Beak and the Mawkin tribe due to having the ability to control the Metroids.
• Suspiciously Similar Substitute: To Old Bird, one of the Chozo who directly raised Samus being a wise and peaceful character who wishes to help Samus. They're so benevolent that even their X copy imparts Quiet Robe's genes to her.
• Token Good Teammate: The Mawkin Chozo on ZDR are all hostile toward Samus, but Quiet Robe instead freezes the purple E.M.M.I. in place and bows to her, indicating this Chozo is meant to be an ally. It turns out Quiet Robe is the last survivor of the Thoha tribe, enslaved by Raven Beak to assist his goal of creating a Metroid army.
• Token Heroic Orc: Incidentally, Quiet Robe's X copy also becomes the only purely good X Parasite seen in the entire series thus far, as the copy somehow manages to retain enough of the original's benevolence to sacrifice itself to help Samus in the end.
• Translation Convention: Referred to in Chozo dialogue as "Henkin Maradis", but in subtitles and English dialogue by the translation "Quiet Robe".
• Undeathly Pallor: After an X parasite merges with Quiet Robe's dead body, the X version's skin becomes pale and its eyes glow white instead of orange.
• Walking Spoiler: They only get two rather short scenes, as both themself and an X parasite, and everything in those scenes massively impacts everything about the plot of both this game and the entire franchise. It's difficult to even mention their name without spoiling the fact there's one good-aligned Chozo still alive.
• Vile Vulture: He looks the part, but its averted; he's a humble scientist who is as benevolent as most of the Chozo, and is more than happy to spill the beans to Raven Beak's plans for Samus, trusting that she won't let it happen. He's such a Nice Guy that even his X clone, a species infamous for their incredible hostility and murderous prowess, ends up copying his kindness and saves Samus from ZDR's destruction.
• You Have Outlived Your Usefulness: After informing Samus of the truth of Raven Beak's plans, Quiet Robe is immediately shot In the Back by a Robot Chozo Soldier controlled by Raven Beak, who no longer has any need for Quiet Robe since his motivations had changed (from cloning Metroids themselves to cloning Samus).

Chozo Groups

Zebes Chozo

Debut: Metroid (statues only), Metroid: Zero Mission (first onscreen appearance)

The Chozo colonists who inhabited Zebes, built Mother Brain, and eventually raised Samus Aran.

---

• Ambiguous Situation:
  • Whether the Zebes Chozo are extinct is up in the air, it is assumed that any survivors of the initial pirate attack fled for somewhere safer, but nothing is confirmed as to what their actual status is.
  • One of their number (Gray Voice) is indirectly confirmed to be a member of the Thoha tribe, but the manga depicts Zebes as a place of gathering in a way that leaves it unclear whether its inhabitants are limited to a single tribe or not.
• Interspecies Adoption: As first shown in the Super Metroid comic and later depicted in Zero Mission, they took in the human Samus after she was orphaned by the Space Pirates.
• Mayincatec: In Zero Mission, their structures have a bit of a "pre-Columbian Mesoamerican" vibe, most notably with the chacmool-like statue that initially holds the first Power Bomb tank.
• Turned Against Their Masters: They might have stood a better chance fending off the Space Pirates if Mother Brain hadn't betrayed them.

Thoha Tribe

Debut: Metroid II: Return of Samus (statues only), Metroid: Samus Returns (first onscreen appearance)

The Chozo who colonized SR388, known by them as Ili Agar Nalima. Upon discovering the X Parasites and realizing the threat the organisms posed, they decided to create the Metroids as the ultimate predator.

---

• Applied Phlebotinum: Some of their technology is powered by "Aeion", the yellowish planetary energy of SR388.
• Build Like an Egyptian: Their ancient buildings in Samus Returns feature quite a few pyramids.
• Godzilla Threshold:
  • Most Chozo have been portrayed in a Friend to All Living Things manner. The fact that they nonetheless created the vicious Metroids to eat the X Parasites shows just how frightened they were of the threat the latter posed to the galaxy.
  • It's revealed in Dread that the Thoha tribe wanted to blow up SR388 because they view the Metroids (and to a lesser extent, the X Parasites) to be that dangerous. Unfortunately, Raven Beak had other ideas and wiped out the Thoha tribe before they could do so, which allowed the events of the Metroid series to begin.
• It's the Only Way to Be Sure: Although they sealed the Metroids away deep in the caverns of SR388, the Thoha tribe feared that the Metroids could either break out or be discovered by others with ill-intent for the galaxy. They proposed to destroy the planet entirely, which will kill both the Metroids and X for certain. They failed because the Mawkin tribe was not willing to let a potential bioweapon go to waste and as a result, the Metroids managed to reach the surface where they are picked up a Galactic Federation ship, kickstarting the whole franchise.
• Meaningful Name: Thoha is likely derived from 鳩 (hato, "pigeon/dove") and Mawkin from 猛禽 (mōkin, "bird of prey"), marking their hawks-vs-doves ideological conflict. It also evokes "Thoth", the bird-headed Egyptian god of knowledge, appropriate for their role as scientists and their tendency to Build Like an Egyptian.
• Proud Scholar Race: More prominent than any other Chozo tribe in franchise, serving as a nice contrast to the Mawkin tribe. They came to SR388 to study the Aeion energy with their mining machines, only to discover the dreaded X Parasites. Using genetic science, they created the Metroids to combat the X, but later lost control of the Metroids when they began evolving into newer, more untamable forms. Since most of them were just scholars and scientists, they enlisted the help of the Mawkin tribe to seal the Metroids away. This ended up being their downfall as the Mawkin killed them all to prevent them from destroying the Metroids.
• Suspiciously Similar Substitute: One of the Thoha is an elderly Chozo who witnesses the X infection of Hornoads and subsequently oversees the creation of Metroids. This is notably similar to Old Bird's role in the Metroid prequel manga. It's unconfirmed whether the elderly Chozo is retconning Old Bird's role, or if it is Old Bird himself.
• Unwitting Instigator of Doom: They didn't intend to make the perfect bioweapon of the galaxy when creating the Metroids to combat the X. By the time they realized what they've created and tried to fix their mistake, they were killed by the Mawkin tribe, the first of many power-hungry factions seeking the Metroids for power.
• Well-Intentioned Extremist: They have good intents, but their methods can be extreme. To combat the X Parasites, they created the Metroids, one of the most dangerous creatures in the galaxy, to devour them. When the Metroids turn against their creators, they sealed them underground and attempted to destroy the planet to be sure. They never got to the last part as the Mawkin tribe wanted the Metroids for themselves.

Tallon IV Chozo

Debut: Metroid Prime

The Chozo who colonized Tallon IV and abandoned most of their technology to live in harmony with nature.

---

• A Fate Worse Than Death: They were pulled from their Higher Plane of Existence by Phazon. They managed to deal with it and return, except for the many that were twisted into insane ghosts by it while sealing the bulk of the stuff away.
• Ascend to a Higher Plane of Existence: It's stated in Metroid Prime that at least some of them achived this, but the Phazon somehow pulled them back down.
• Beware the Nice Ones: One of their lore entries warns that people who respect their relics will be treated as friends, but those who thoughtlessly destroy their works "will know the wrath of the Chozo, unfettered and raw."
• Future Imperfect: An early Chozo Lore log entry claims that their history "stretches back into ancient times, so far into the fog of the past that we know not where our ancestors came from." It's implied that this is related to the ancient colonists' decision to abandon their higher technology and become Space Amish.
• Our Ghosts Are Different: Some left their bodies and the game's dimension behind; later, they returned to the game's dimension, still without those bodies. The ones that got stuck in the game's dimension because of Phazon madness are what the other creatures call ghosts. The Chozo call them the turned.
• Seers: Those on Tallon IV had visions of the future and foretold Samus' arrival, but they were not perfect visions.
• Space Amish: More so than the other Chozo colonies, they ditched their advanced technology to live in harmony with nature. Granted, there do seem to be quite a few advanced bits of technology around their ruins, though it's ambiguous how much of it is theirs and how much was introduced later by the Space Pirates.
• We Have Become Complacent: The Tallon IV colony had decided to give up all but the most basic technology and live in harmony with nature. This unfortunately made dealing with invaders and star born plagues more difficult, but they did discover some new tricks such as prophecy, and managed to MacGyver enough things till Samus came, like their visions foretold. Still, some of the machines found on Tallon IV are mere first and second generation equivalent drones, from a society with multiple millennia of continuity.

Chozo Ghosts

Debut: Metroid Prime

The spirits of dead Chozo from Tallon IV, twisted into abominations by Phazon.

---

• Abusive Precursors: Due to Phazon exposure. The insanity caused by phazon seems to have a much greater effect on entities without physical forms.
• A Fate Worse Than Death: They had their higher plane status revoked before being corrupted.
• Came Back Wrong: They ascended to a higher plane but became monstrous parodies of their former selves.
• Face–Monster Turn: Had no choice to avoid becoming evil monsters and in fact seem tormented by their fates. Their evil is entirely the work of Phazon. They're even called the Turned by other chozo.
• Heel–Face Turn: After Samus collects all 12 Chozo Artifacts, they manage to regain their free will long enough to repair the portal into the Impact Crater.
• Intangible Man: Not that they need it.
• Invisibility: They're fond of appearing just long enough to shoot you before vanishing from sight.
• Kill the Lights: A tell that they are around is a dimming of lights.
• MacGuffin Guardian: Three of the four Chozo Artifacts located in the Chozo Ruins are either guarded by (Samus must defeat three of them to acquire the Artifact of Wild from the Sunchamber) or at bare minimum are located in the same room as the ghosts (the Artifact of Chozo in the Life Grove and the Artifact of World in the Hall of Elders).
• Mercy Kill: Even the Chozo thought they would be better off dead.
• No-Sell: Almost every fancy weapon you collected throughout the game? Useless. Only the basic Power Beam and its derivatives can hurt them. Luckily, this includes Super Missiles.
• Our Ghosts Are Different: Energy beings whose minds have been subsumed by the Phazon.
• Religious Bruiser: They tend to congregate around areas most sanctified by the Tallon IV colony.
• Screaming Warrior: Presumably in agony, but they shriek a lot.
• Tragic Monster: Had no choice to avoid becoming evil monsters and in fact seem tormented by their fates. Their evil is entirely the work of Phazon. They even do a collective Heel–Face Turn once freed from the Great Poison.

Elysia Chozo

Debut: Metroid Prime 3: Corruption

Chozo colonists who built the floating settlement of SkyTown in the atmosphere of Elysia as a base to observe and research deep space. They built the Elysians to help them maintain the facilities and eventually left SkyTown entirely in the hands of the intelligent machines.

---

• The Ghost: Unlike all the other Chozo tribes, who we see in-person, in flashbacks, or as undead, we never see the Elysia Chozo at all, only their statues and robots.
• The Smurfette Principle: The Chozo Searcher mentioned in Elysian scan data is to date the only explicitly female Chozo in Metroid lore (unless you want to count Samus due to her Chozo DNA Bio-Augmentation).
• Uncertain Doom: The other Chozo colonies we know about were wiped out by Space Pirates, Phazon, Metroids, or other Chozo. It's more ambiguous with the Elysia Chozo, as they're merely stated to have left the planet. Even the Elysians don't know for certain what happened to them, which is one reason why they sent out probes to survey the cosmos.

Mawkin Tribe

Debut: Metroid Dread

The Chozo of ZDR, known by their people as Ili Tarin Nalima. Unlike the other Chozo tribes, these Chozo never gave up their warrior ways, as evident by their military factories spread across the planet. They have no benevolent intentions as they were responsible for slaughtering the Thoha tribe on SR388 after sealing the Metroids away.

---

• Abusive Precursors: These are not the benevolent bird race that the galaxy has come to know the Chozo as. They are conquerors who worship power and order, and the Metroid crisis throughout the main series can be traced to them killing the Thoha tribe before they could destroy SR388.
• Angry Guard Dog: The Armadiggers are implied to be this via a mural in Elun, due to them wearing the same collar as Kraid, albeit smaller and more easier on their necks.
• Bad People Abuse Animals: They're shown to capture, experiment on and even torture ZDR's lifeforms, and they are not a benevolent tribe of Chozo.
• Bioweapon Beast: In their genetic laboratories, they have been cloning and experimenting lifeforms for their bioweapon program, including Experiment No. Z-57. This is why they want the Metroids so badly since they are the perfect bioweapon minions to rule the galaxy.
• Brutal Bird of Prey: The Mawkin are depicted as bipedal raptors, all of whom are imperialistic warmongers seeking to conquer the galaxy.
• Build Like an Egyptian: Just like their Thoha relatives, though it's murals from Egyptian pyramids depicting various points in their lives such as massacring the Thoha Tribe, as well as fighting the Space Pirates, rather than actual pyramids.
• Cavalry Betrayal: Played with. The Mawkin collaborated with the Thoha to quarantine the Metroids underground in SR388, which they did in fact do to the best of their ability despite the losses to their side no strings attached. It was when the Thoha decided they should destroy SR388 to prevent the Metroids (and presumably the X as well) from ever becoming a threat again that the Mawkin Chozo turned on them and massacred the tribe, wanting to control and use the Metroids as bioweapons, and only sparing Quiet Robe to use one last Thoha for that end.
• Eternal Engine: In contrast to the mostly stony, low-tech ruins on other Chozo worlds, the ZDR colony has many factories and other mechanical structures. This makes sense as they are a warrior tribe.
• Evil Versus Evil: A mural in Ferenia shows them in conflict with the Space Pirates, who beat them to the punch in weaponizing Metroids.
• Fed to the Beast: A Chozo Archives picture shows the Mawkin soldiers pushing Chozo prisoners into the maw of Drogyga. Based on their beak and body structure and eye color, these prisoners were fellow Mawkin Chozo, sentenced for either failure or protesting Raven Beak's rule.
• Greater-Scope Villain: As seen by the Chozo Memories, they were the reason why SR388 is devoid of any Chozo inhabitants. And it's later revealed in Dread that they were responsible for the Metroid and later X Parasite crises, as they stopped the Thoha tribe from destroying SR388 and unwittingly brought the X to their homeworld, allowing the dangerous species to live past their supposed extinction event.
• Irony: Despite being the first villainous faction that wanted Metroids as minions in their ranks, they never got the chance due to an X Parasite infecting all of them, save for their boss Raven Beak, who left them behind to save his own skin.
• Kick the Dog: They're shown to subjugate, experiment, and even torture the various lifeforms on ZDR, including the bosses like Kraid and Experiment No. Z-57. It says something when you feel more sorry for a Space Pirate commander than you do for the Mawkin tribe.
• Laser-Guided Karma: They slaughter the Thoha tribe of SR388 for refusing to let them use the Metroids as beasts of warfare, and as a result an X Parasite hides amongst their warriors and decimates them all until only Raven Beak is left. For some additional irony, the Metroids they sought to weaponize were created specifically to prey on the X, as well as attack Mawkin Chozo since they were programmed by the Thoha to do so.
• Meaningful Name:
  • Mawkin is likely derived from 猛禽 (mōkin, "bird of prey") and Thoha from 鳩 (hato, "pigeon/dove"), marking their hawks-vs-doves ideological conflict.
  • The word "mawkin" (including variants maukin and malkin) also has a few meanings somewhat relevant to their role in Metroid Dread, including "scarecrow", "simpleton" and "mop for cleaning cannons". "Malkin" as a word for felines is mostly used in the context of "Grimalkin", a witch's black cat (and the X-infected Mawkin who defend Raven Beak, their bodies composed of black ooze, are evocative of familiars in a Deal with the Devil).
• Missed Him by That Much: It's suggested through the completion arts and murals throughout locations like Ferenia (as well as the enigmatic body outside of Kraid's lair) that a group of Mawkin may have been on Zebes during the events of Super Metroid, seemingly in the process of fighting off the Zebesian Space Pirates (and capturing the wounded Kraid) before its destruction just as Samus was on it, presumably under orders from Raven Beak to attempt to capture the Baby Metroid, as it was the last Metroid in existence at that point, that proved fruitless when Mother Brain killed it and the planet was destroyed in the end.
• Proud Warrior Race Guys: They worship at the altar of power, refusing to give up their ancient warrior ways unlike the rest of the Chozo tribes. And their idea of sharing prosperity is galactic domination.
• Putting on the Reich: The image unlocked after getting all the items in Hanubia depicts a group of Mawkin warriors standing in formation with battle standards, not too dissimilar to the Nazi Party rallies in Nuremberg. Fittingly, their goal is to establish an Chozo-ruled galactic empire with themselves at the top and every other race either enslaved or destroyed.
• Red Eyes, Take Warning: As shown in the Chozo Archives, as well as official artwork of both regular Chozo Soldiers, all Mawkin have red eyes when they aren't being infected by X Parasites.
• Sole Survivor: Raven Beak is the last Mawkin alive in the present, as all the others were infected by the X. In a looser sense, Samus Aran can later be considered the last Mawkin after killing Raven Beak as she has his DNA.
• Unwitting Instigator of Doom: One of the Mawkin soldiers was an X Parasite in disguise when the tribe returned to ZDR. By the time they realized it, it was too late. The X Parasite spread uncontrollably, wiping out the entire tribe save for Raven Beak himself, who narrowly sealed them away. It is thanks to them that the X Parasite escaped their supposed extinction in Fusion.
• Vestigial Empire: With the exception of Raven Beak, the Mawkin have been wiped from the face of ZDR by the time of Dread as a result of an X Parasite infestation. All that's left of their civilization at that point are ruins and abandoned but functioning facilities, and Raven Beak's Chozo soldiers (all now X mimics) have all been replaced with robots and Bioweapon Beasts.

Chozo Soldiers

^{Click here to see their appearance when infected by the X}

Debut: Metroid: Zero Mission (murals and artwork), Metroid Dread (first in-game appearance)

Before they settled into the role of peaceful stewards for the galaxy, the Chozo had mighty warriors among their ranks. The weapons and armor they wielded would eventually be passed onto their human ward, Samus Aran — but as she ventures into ZDR, there are still Chozo soldiers out there who are hostile to her.

---

• Bad Black Barf: In the second phase of their battle, the red and Elite Chozo Soldiers gain the ability to spit a damaging beam of Ominous Obsidian Ooze aimed at Samus while clinging to the wall.
• Bait-and-Switch Boss: Samus easily defeats E.M.M.I.-07PB as a Cutscene Boss by draining its energy, but then a red Chozo Soldier hops into the area and serves as the actual boss before she can claim her prize.
• Contrasting Sequel Antagonist: To the Chozo Ghosts. While the Ghosts were only antagonistic towards Samus due to Phazon corruption and insanity, the Chozo Soldiers were loyal to Raven Beak and would likely have fought her even without becoming hosts to the X. While the Chozo Ghosts were spectral entities that lashed out with spiritual power, the soldiers fought with their physical strength and weapons. The Chozo Ghosts tend to attack in groups of three, while the soldiers are always face Samus one-on-one. Furthermore, the Chozo on Tallon IV took years to completely fall to the corruption, allowing them to make preparations for Samus to arrive, while those on ZDR fell to the X in a very short amount of time, making Raven Beak's plans fall apart somewhat.
• Double Weapon: Their main melee weapon is a double-bladed spear.
• Elegant Weapon for a More Civilized Age: Despite having advanced technology such as Powered Armor and various ranged weapons like power beams and missiles, Chozo Soldiers still frequently use melee weapons such as spears.
• Elite Mooks: The Elite Chozo Soldier is the strongest Chozo Soldier, has the most resilient shield, and wears golden armor.
• Gold-Colored Superiority: The golden-armored Elite Chozo Soldier is fittingly enough the strongest variant of Chozo Soldier.
• Law of Chromatic Superiority: Chozo Soldiers in ZDR come in three armor colors: grey, red, and gold. The gold one is outright confirmed to be an Elite Chozo Soldier, while the red ones are also implied to be commanders since one can be seen ordering regular grey troops in image 02 of the Chozo Archive gallery. In gameplay, the red and gold soldiers also have access to retractable shields that they use for defense and attacking which the grey units seem to lack entirely; the Elite Chozo Soldier in particular has a much more resilient shield that also requires the use of the Grapple Beam to destroy instead of just a Melee Counter.
• Luckily, My Shield Will Protect Me: Some soliders wield shields to protect themselves and capable of using them to Shield Bash. Samus is able to destroy the shields with enough damage, a Melee Counter, or (in the Elite Chozo Soldier's case) the Grapple Beam.
• Mini-Boss: The Chozo Soldiers' role in Metroid Dread is acting as short boss battles.
• Monster Knight: They are Bird People fully clad in armor wielding spears and occasionally shields. They become a lot more animalistic once the X Parasites stop pretending to be Chozo.
• Monstrous Humanoid: Once Samus damages one enough to show that they are actually an X Parasite, its head morphs into becoming one huge maw oozing with black substance.
• Ominous Obsidian Ooze: The Chozo Soldiers fought in Dread are actually infected by X Parasites. As with other X-infected creatures in the game, their bodies are formed by a black ooze-like substance, and revert back to this appearance as they take more damage. These X-infected Chozo even weaponize the black ooze as their Bad Black Barf and Shockwave Stomp attacks.
• Pre-Final Boss: An Elite Chozo Soldier is the final challenge before Raven Beak.
• Recurring Boss: Samus fights five Chozo Soldiers while on ZDR.
• Red Eyes, Take Warning: Like other Chozo of the Mawkin tribe, these dangerous Chozo Soldiers have red eyes. The fact that the Chozo Soldiers encountered in Dread have white eyes instead is a subtle indicator that they're actually X-infected before they Turn Red.
• Sealed Evil in a Can: Due to being infected by X Parasites, all Mawkin Chozo were quarantined in Elun, where Samus fights the first Chozo Soldier. Raven Beak releases them shortly afterward, allowing more Chozo Soldiers to appear in other areas.
• Shockwave Stomp: In the second phase of their battle, the Chozo Soldiers' Sword Plant generates a shockwave of Ominous Obsidian Ooze across the floor.
• Small Role, Big Impact: The Chozo Soldier first infected by the X Parasites is only mentioned once and appears once in an unlock able Chozo Archives picture. But they're responsible for the X outbreak that wiped out the Mawkin and delayed Raven Beak's planned galactic conquest with the Metroids, thus why the series Greater-Scope Villain took until Dread to become a threat.
• Sword Plant: They have an attack where they jump and stab their weapons on the ground.
• Turns Red: After taking sufficient damage, Chozo Soldiers will reveal their X infection and proceed into the second phase of their Mini-Boss battle. Once this happens, their movements become faster, their melee strikes cover more range, their Sword Plant becomes a Shockwave Stomp, and red and Elite Chozo Soldiers gain a Bad Black Barf attack.
• Villainous Breakdown: When first encountered, Chozo Soldiers have a cool, calm demeanor as they make elegant and precise movements befitting a proud race of dignified warriors. But when they take enough damage and enter the second phase of their battle, this composure is stripped away as their attacks, movements, and behaviors become a lot more bestial and animalistic. This is more likely due to them being X Parasites rather than actual Chozo.
• Wall Jump: They often jump off the walls in their fights against Samus.

Automatons

Debut: Metroid II: Return of Samus

The Chozo colonies on SR388 and ZDR created many robots, whether part of the Chozo Security System or for serving other purposes. With both civilizations having since collapsed, these automatons mindlessly continue their programmed tasks, even as they malfunction and serve no one.

---

• Adaptational Badass: Like many other enemies from Return of Samus, the robots that appear in the remake Samus Returns are much tougher enemies, both dealing more damage while becoming more resistent to damage.
• Adapted Out: Autom, Proboscum, Shirk, and TPO do not appear in Samus Returns, the remake of Return of Samus.
• A.I. Is a Crapshoot: Due to a lack of maintenance over the years, these robots are malfunctioning and have gone out of control (seemingly accounting for why they attack Samus), as described in the case of Proboscum in the manual:
  Originally programmed as a worker, not a fighter, this robot is out of order and out of control.
• All There in the Script: Robotsmall and Robotbig are only named in the internal data of Samus Returns. Autector, Autool, and Shakernaut are only named in the internal data of Dread.
• Artifact Name: Since Autoads are no longer Hopping Machines in Samus Returns, any similarities to toads are lost.
• Booby Trap: When Samus approaches an Autector attached to the floor (given away only by the red light in its center), it springs up and then explodes. Even if Samus isn't caught in the blast radius, the loud sound can alert a nearly E.M.M.I. to her presence.
• Composite Character: In Samus Returns, Gunzoo and Autom appear to be combined into a single enemy, which has the name and appearance of Gunzoo and the behaviors (movement restricted along a single axis, firing continuous beams as its attack) of Autom.
• Cyber Cyclops: The Chozo are apparently big fans of designing their robots with a single eye. This can be seen with Autclast, Autoad, Robotsmall, Robotbig, and Shakernaut.
• Deadly Disc: The Autsharp generates a spinning energy blade, turning itself into a sawblade.
• Eye Beams: The Shakernaut can fire a powerful laser beam from its eye.
• Fire-Breathing Weapon: Automs and Flame Wallfires have flamethrowers of the sucky video game variety, while Fireball Wallfires spit fireballs. They can't do much damage to Samus, especially not with the Varia Suit, but are still best avoided.
• Helpful Mook:
  • Proboscums act as platforms for Samus, although due to their malfunctioning nature she cannot stand too long on them.
  • Although Autools can be bothersome while escaping from E.M.M.I., they drop a ton of energy and ammunition when destroyed.
• Hopping Machine: In Return of Samus, Autoads live up to the "toad" part of their name by constantly hopping around.
• Invincible Minor Minion: Automs cannot be destroyed, only avoided. Proboscums are invincible too, but they can't hurt Samus.
• Mana Burn: In Samus Returns, Autoads drain your Aeion gauge and temporarily disable your Aeion abilities in the process.
• Meaningful Name: The Gunzoo has multiple guns. The Proboscum has an appendage resembling a large nose. The Wallfire is mounted on walls and shoots fireballs. The Robotsmall and Robotbig are small robots and big robots, respectively. The Autector is a tripmine activated when it detects Samus's presence. The Autsharp resembles a sawblade. The Autsniper is a turret.
• Mecha-Mooks: These robots act as enemies in their appearances.
• Mini Mook: Robotbig, Autclast, and Shakernaut both resemble miniature versions of Diggernaut.
• No-Sell: In Dread, robots are impervious to uncharged beams until the Plasma Beam is acquired.
• Non-Indicative Name: Autracks do not move on tracks, nor do they track Samus's movement in Return of Samus (though they do so in Samus Returns). Although official art does give them tank-like treads, they are almost totally stationary in-game, only extending their necks to attack.
• Shockwave Stomp: The Autclast and Shakernaut can Ground Punch so hard, it creates a shockwave of flames across the surface.
• Spikes of Villainy: "Villainy" is definitely overstating it, but the Shirk is an enemy that is programmed to crush targets with its sharp nails.
• Suspiciously Similar Substitute: The Autsniper in Dread is a robot Chozo turret that aims at Samus's position and fires, much like the Autrack in Samus Returns.
• Theme Naming: Many robots have names beginning with the letters "aut-". Although it's never explicitly stated, this prefix presumably means "automaton", hence the name of this folder.
• Underground Monkey: Samus Returns introduces Black Wallfires, Black Autracks, and Black Autoads. These can only be destroyed using Power Bombs or the Beam Burst.
• Unique Enemy: In Return of Samus, several robots are very rare:
  • Only a single Shirk is found in the entire game, located in Phase 4. Two Automs, which are the only ones in the game, share the same room as the Shirk.
  • Only two Gunzoos are in the game, both located in the Chozo ruins in Phase 7.
  • While TPOs and Proboscums are more common, each one is only found in a single room.
• Weak Turret Gun:
  • The Wallfires are turrets that are shaped like bird (or Chozo) heads found within Chozo ruins. In Return of Samus, they can be wrecked with a single shot of Samus's basic Power Beam. While their attacks produce considerable Knock Back, they only shoot periodically in a fixed direction and angle, so all Samus has to do is be patient and wait for an opening.
  • Starting in Phase 3 of Return of Samus, you'll start encountering Autracks, which are stronger gun mounts with extendable "necks" and a more frequent firing rate than Wallfires. However, by then, you should have the Ice Beam, which can freeze them and their shots, or the Wave Beam, which lets you whittle them down from behind cover. In the event you meet one on level ground, you can just duck underneath their shots.
  • In Dread, Autsnipers can take quite a beating compared to the turrets from Return of Samus, except they are vulnerable to the Melee Counter just before they fire. This stuns them and leaves them open to an automatically-charged countershot that immediately destroys them.

Torizo

Debut: Super Metroid

"The statues are our sentinels: blind but ever watchful, they are and have always been, repositories for our most precious secrets and strongest powers. The crafting of each is a long and sacred process, performed only by those Chozo who have lifetimes of experience in such things. We have left these relics on planets across the solar system. Some are merely reminders: silent emblems of the Chozo that serve as icons of peace in lands that know only war. Others wield subtle strength, exerting their influence in ways beyond the understanding of mortal creatures. Still others are guardians of our secret ways, and these can be as terrible as they are beautiful. Those who respect and honor these relics will know the friendship of the Chozo. Those who deface or destroy them will know our wrath, unfettered and raw."

— Tallon IV, Hieroglyphic Engravings

Statues created by the Chozo that are potent defense systems or attack golems. At first, they appear indistinguishable from the benefactor Chozo Statues that hold Samus's upgrades, but then they surprise her by coming to life and attacking her.

---

• Bullet Catch: The Golden Torizo will grab super missiles out of the air and throw them back at Samus. Fortunately it can only grab them one at a time, making super missile spamming a viable option.
• Cranial Processing Unit: Averted. The first Torizo boss in Super Metroid continues fighting after its head is destroyed.
• Dodge the Bullet: Golden Torizo, again. It's almost impossible to hit with normal missiles.
• Dub Name Change: Torizo are simply known as Chozo Statues in Japanese. Giving them a distinctly different name is an addition made by the English localization.^note The kanji for "bird", seen in the name of the Chozo and their statues, can be read as either chō or tori.
• Eye Beams: The Golden Torizo can shoot energy rings from its eyes. When it blinks, the rings explode where they hit the ground.
• Gold-Colored Superiority: The Golden Torizo in Norfair is much stronger and tougher than the normal Torizo in Crateria.
• Golem: Maybe? They certainly look like stone, but they could just be stylized robots. Plus they were susceptible to Metroid predation and X infection, which could only affect organic material.
• Grenade Spam: Both Torizo statues can launch a large number of item spheres from their beaks. Rather than providing new upgrades, these promptly explode upon hitting the ground.
• Inescapable Ambush: The doors lock when they attack.
• Law of Chromatic Superiority: The most powerful Torizo is gold, while the others are grey or brown.
• Living Statue: They look just like ordinary Chozo Statues, but then they come to life and combat Samus.
• Mistaken for Granite: The combat Torizo are identical to the ones that harmlessly hold upgrades. That quickly changes one they activate.
• The Unfought: There is a third Torizo in Super Metroid, located in Tourian. It's already been drained by the Metroid Hatchling by the time Samus arrives, and is Reduced to Dust with the slightest touch.
• Weaponized Offspring: As a last-ditch attack, the Golden Torizo releases eggs, which promptly hatch into mechanical chicks that attack Samus.

Hive Mecha

Debut: Metroid Prime

"A design flaw makes the shielding on Hive Mecha weak around their access ports. These units are second-generation combat drones, able to interface with organic units at a higher level. They train, shelter, and work with hive dwelling predators. Unarmed, they rely on their hive beasts to handle any threats."

—Scan Data

A combat drone created by the Chozo to protect the ruins of Tallon IV. Nurtures a nest of vicious Ram War Wasps within it. Fought in the Hive Totem.

---

• Attack Drone: Unlike your typical drone though, it's stationary. The War Wasps actually act more drone-like than it.
• Attack Its Weak Point: It can be damaged by firing at the hatches that release the War Wasps, once they're open.
• Bee-Bee Gun: The Chozo made this machine to weaponize War Wasps.
• Flunky Boss: It's sole attack is to release the Ram War Wasps that live inside it.
  Scan Data: Unarmed, they rely on their hive beasts to handle any threats.
• Pest Controller: It controls the War Wasps by emitting signals for them to attack.
• Wake-Up Call Boss: The Hive Mecha is intended to be the first boss fought upon landing on Tallon IV, but it can give first-time players much more trouble than the Parasite Queen before it. It traps the player on a small platform in the center of the room while having them encircled by targets too fast to keep a lock on. If the player doesn't learn to use the Combat Visor's radar to keep track of surrounding enemies, they'll find themselves getting repeatedly potshot by the Ram War Wasps.

Incinerator Drone

Debut: Metroid Prime

"Device schematics indicate a high risk of malfunction when internal power core is damaged. Unit has minimal combat programming, but can defend itself if necessary. This drone's intense heat blasts compensate for its lack of battle prowess."

—Scan Data

Another combat drone created by the Chozo. Fought in the Burn Dome of the Chozo Ruins.

---

• Attack Drone: And just like the Hive Mecha, it is stationary as well.
• Attack Its Weak Point: It has a core. You know what to do.
• Fire-Breathing Weapon: It's a robotic flamethrower primarily used for garbage disposal, but it also functions as a defense mechanism.
• Flunky Boss: Accidental example. If its core is shot enough times, its firing mechanism will malfunction and burn the hive of Barbed War Wasps right above it, pissing them off.
• Mundane Made Awesome: It's a glorified trash burner that doesn't even look that advanced by Chozo standards, yet it's treated as seriously as any other boss, receiving epic boss music and everything.

Ruins Test

Debut: Metroid: Zero Mission

Found deep within the Chozo Ruins of Chozodia, the Ruins Test appears to be a large and impressive mural decorated with hieroglyphics depicting the God of War. During Samus's Zero Mission, the Ruins Test comes to life and the God of War manifests as a ghostly entity that tests Samus's will and proves that she is worthy of the Fully Powered Suit.

---

• All There in the Manual: Its only official English name, the Ruins Test, is derived from the Nintendo Power guidebook.
• Attack Its Weak Point: The God of War is holding a glowing orb, which is its only vulnerable spot. When the orb displays a Power Suit symbol instead of her reflection, Samus must shoot the orb. She must do this four times in order to pass the Ruins Test.
• Dark Is Not Evil: The room turns dark while the Ruins Test is active, its battle theme is an Ominous Pipe Organ, and its subject is a War God. However, it is simply a test that proves Samus's willpower, restores her lost Power Suit, and rewards her with the most powerful items in the game.
• Kill the Lights: When the Ruins Test projects itself as a ghostly entity, the room turns much darker, even though there is no apparent light source to extinguish. Once the test is passed, the lights come back on.
• Our Ghosts Are Different: The God of War appears as a ghost or spirit when it emerges from the mural, although its exact nature is uncertain.
• Shock and Awe: It attacks by casting lightning bolts upon the ground.
• Stop Hitting Yourself: The Ruins Test's orb usually shows Samus's reflection. If Samus shoots the orb during this time, she hurts herself.
• Threshold Guardians: The Ruins Test is meant to test one's resolve and will. By overcoming it, Samus proves that she is worthy of the legendary Fully Powered Suit.
• Tron Lines: Whenever the Ruins Test is about to use its lightning attack, the outlines of the God of War's mural glow with a bright neon blue light.
• Turns Red: As the battle progresses, the Ruins Test speeds up, and its lightning attacks begin producing shockwaves that travel along the floor and walls.
• War God: It is referred to as the God of War in Japanese sources, including an interview with Yoshio Sakamoto on the Zero Mission website.

Elysians

Debut: Metroid Prime 3: Corruption

A race of robots built by the Chozo to help maintain the SkyTown facility and eventually given self-awareness. When the Chozo left Elysia, they left their mechanical progeny in charge. The Elysians continued their creators' task of researching the cosmos until a shortage of fuel and supplies required them to enter a centuries-long hibernation. The Galactic Federation eventually woke them up and negotiated a treaty where the Elysians would be given supplies in exchange for sharing their research data. Unfortunately, the impact of the Leviathan would result in the Elysians being driven mad by Phazon.

---

• Benevolent A.I.: They were utterly devoted to their Chozo creators and got along well with the Federation as well. Only being unwillingly corrupted by Phazon was able to turn them evil.
• Book Ends: The first line of the first Elysian lore and the last line of the last Elysian lore are: "I am Elysian, descendant of both the Chozo and the First. I am facing the last moments of my life and transferring my memory to the data pod."
• Brainwashed and Crazy: Phazon corruption really did a number on them, a problem only worsened by the liberties Ghor took with hacking them after he arrived in Skytown.
• Do Androids Dream?: Elysians installed the ability to "dream" in themselves so that they could be alerted to happenings while they "hibernated". They claim to have seen forms of their builders in between their operational sessions, but given the Talon IV Colony's established abilities, there may have been more to that incident than what the installed dreams were supposed to cover.
• Gameplay and Story Integration: The scan logs detailing how they sent research probes into space aren't just flavor lore. Samus can also send out probes from a room on Elysia to scan the various planets in the game, which will put markers on rooms with hidden items.
• Let's You and Him Fight: The Elysians nearly got into a fight with the first Federation expedition due to the latter being heavily armed when they landed. Fortunately, the Federation was quickly able to clear up the misunderstanding.
• Uncertain Doom: It's not clear if the various mechanisms encountered throughout the game are the intelligent Elysians referred to by scans or lesser robots they created. If it's the latter, the true Elysians may well have been completely destroyed by the corruption. If it's the former, there's still some hope they can recover.

Steamlords

Debut: Metroid Prime 3: Corruption

Elysians with potent repair and combat capabilities, reduced to little more than drones by Phazon corruption and Ghor's hacking.

---

• Badass Cape: Powerful robots who wear capes, though it's best not to question where they got the cloth.
• Combat Medic: They can repair the other robots of Skytown, even those blasted into inactivity, making it impossible to clear out certain rooms without killing them first.
• Deader than Dead: After Samus acquires the plasma beam, her beam shots will melt the steambots beyond repair, preventing the steamlord from reviving them.
• Flight: Typically they just hover, but dropping a bridge out from under one just causes them to fly away rather than fall to their death.
• Flunky Boss: They always appear with a few steamboat minions, which they revive whenever they die.
• Invisibility: The only time they're visible is when they're attacking or reviving one of their lackeys. The x-ray visor can see them despite the cloaking.
• It Can Think: Scans of vaporwings and steamspiders reveal that they were creations of the steamlords. Whether they were the intelligent Elysians referred to in the scan lore or simply particularly intelligent drones with a degree of freedom is up in the air.
• Lean and Mean: They're thinner than just about every other enemy in the game, being little more than mechanical bones.
• Mini-Boss: They're of a smaller scale than all the other bosses in the game, including the other minibosses.
• Power Floats: The most powerful beings encountered on Elysia, barring the other bosses, and they constantly float above the ground.
• Recurring Boss: Four steamlords are encountered through the game.
• Shock and Awe: They attack Samus and revive steambots with arcs of lightning.
• Skull for a Head: A holographic one, but still. Closer examination reveals it to actually be a depiction of Ghor's head, though given that his head is still quite skull-like, the principle remains.

Defense Drone

Debut: Metroid Prime 3: Corruption

A powerful combat robot defending the boost ball upgrade on Elysia.

---

• Armless Biped: Its general design, though it does have a cannon limb situated in the middle of its upper body.
• Attack Its Weakpoint: Its control module, which must be exposed by shooting its sensory antennae and grappling open its outer casing.
• Cyber Cyclops: A large robot with one eye.
• Homing Projectile: The plasma bomb, which can make hairpin turns. The mines it fires when its core is exposed also home in after a few bounces.
• Macross Missile Massacre: It can fire many missiles in a rapid salvo.
• Ominous Fog: Once its health drops low enough, it vents obscuring fog when its control core is exposed.
• Shockwave Stomp: It can hop into the air and land in an electrical shockwave.

Helios

Debut: Metroid Prime 3: Corruption

A powerful Elysian robot chosen as the guardian of the Elysia Leviathan.

---

• A.I. Is a Crapshoot: Not of his own programming. He has been corrupted by Phazon.
• Ambiguous Gender: One would assume he would have none at all, being a robot, but the scan visor says that Helios is male.
• Beam Spam: One of the shapes it may take with its swarm is diving them up into rings of six, and having each ring fire a powerful beam at you.
• Chainsaw Good: Though Helios primarily relies on his Swarmbots for attack and defense, he is not completely defenseless on his own.
• Deadly Disc: One of the shapes he may take with his Swarmbots.
• Dual Wielding: Wielding dual chainsaws two years before Madworld.
• Hive Mind: It controls thousands of Swarmbots through wireless communication.
• Killer Robot: Helios's original function, much like the swarm bots, is unknown but Phazon has turned them into killers.
• Meaningful Name: The Swarmbots all revolve around Helios, both figuratively and literally in many cases.
• Multiarmed And Dangerous: The robot has four arms.
• Rolling Attack: Another of his forms.
• Spin Attack: One form he may take is to lay himself on the ground and have his swarmbots form a tornado-like swirling shape above it, and proceed to slide across the ground.
• Synchronized Swarming: He uses five formations in particular.
• The Worm That Walks: One shape it takes is to have the Swarmbots form into four limbs for a vaguely human-like appearance.

Diggernaut

Debut: Metroid: Samus Returns

A completely new boss introduced in Samus Returns, not being present in the original Metroid II. A Chozo robot used for mining operations in SR388, it went rogue at some point after the Chozo vanished from the planet.

---

• Advancing Wall of Doom: It forms one of these with its drills to use in a chase scene. it later uses a variation of the tactic during its boss fight.
• A.I. Is a Crapshoot: Even after the Chozo left the planet, it's still functional and digging through SR388. It also attacks any intruders it comes upon, despite being just a mining robot.
• Ambiguous Situation: It's not clear if Diggernaut is attacking Samus because it has gone haywire or if its regular security protocols have Gone Horribly Right in targeting intruders. Even the official Prima Guide brings up this ambiguity. Muddling things further is its tendency to inhale any Chozo Statue powerups it finds, which seems to be either a skewed attempt to follow its mineral-collecting directives or a deliberate effort to keep them out of Samus's hands.
• Background Boss: For much of the fight it stands in the background where Samus can't reach it while swinging its drill arms at her.
• Call-Back: Its drill arms and head have markings resembling the Spider Ball tracks in the Metroid Prime Trilogy, indicating that Samus can use the Spider ball to climb onto those surfaces.
• Cyber Cyclops: It has a single red eye.
• Energy Weapon: It can fire those from its giant, mechanical eye.
• The Juggernaut: Fitting for his name, it persistently tries to kill Samus during a section of the game. It's also a Marathon Boss to boot.
• Killer Robot: It's very deliberately trying to kill Samus despite being designed as a mining robot. Once it believes that she died after their Area 4 encounter, it quickly leaves.
• King Mook: Subverted. Diggernaut is a much larger version of the mining robots seen throughout Area 3. However, only Diggernaut becomes hostile to Samus and the lesser mining robots remain harmless set pieces.
• Not Quite Dead: After defeating it in the boss fight, it tries to get up for another round.
• Offhand Backhand: After the boss fight, Samus blows its head into pieces without even looking at it as she goes to collect her upgrade.
• Red Eyes, Take Warning: Obviously, this giant, murderous robot boss can't have anything else but a single, glowing red eye.
• Shockwave Stomp: After Samus damages the rotative mechanism of its drills, it has to resort to this by using them as blunt weapons.
• Super-Powered Robot Meter Maids: It is a mining robot, which is also a surprisingly competent killer for a machine with a relatively mundane design purpose, is equipped with lasers in addition to giant drill arms capable of killing Samus in one hit, and happens to be one of the toughest bosses in Samus Returns.
• This Is a Drill: Both of its arms are equipped with gigantic drilling mechanisms.
• Ungrateful Bastard: When Samus first encounters Diggernaut, it's powered off and blocking Samus's way forward. After she powers it back up with the Grapple Beam, it walks off into the background. What does Diggernaut do once it sees Samus again? Tries to kill her with its drills.

Central Units

Debut: Metroid Dread

^{Click here to see them without their armor}

Familiar-looking managers of the E.M.M.I. zones that provide Samus with the power of the Omega Cannon.

---

• Brain in a Jar: Once Samus strips them of their protective metal casing, they are revealed to resemble floating blue brains with a single unblinking eye.
• Broken Armor Boss Battle: The Central Units are covered in a blue-black plating that must be repeatedly shot at to blow it off, revealing the vulnerable floating brain underneath.
• Cores-and-Turrets Boss: The Central Unit itself simply floats in mid-air watching Samus while it lets the turrets around the room and the periodically-appearing Rinkas do all the fighting. Even when its Destructible Armor gets blown off it doesn't actually change its strategy.
• Mini-Boss: Their functional role in the E.M.M.I. zones, and defeating them gives Samus the Omega Cannon Power-Up to destroy the zone's E.M.M.I.
• Suspiciously Similar Substitute: Of Mother Brain, as similar but presumably far less powerful A.I.s of Chozo origin that heavily physically resemble her and are defended by laser turrets and Rinkas. They also bequeath a super-strong beam weapon upon defeat, similar to how Samus got the Hyper Beam from Mother Brain by way of the Metroid hatchling.
• The Unfought: You don't get a chance to fight the final Central Unit since Samus using her Metroid powers to drain out the last E.M.M.I. also short-circuits the Central Unit.
• Villain Forgot to Level Grind: Although later Central Units tend to use more cannons and Rinkas, the Central Units themselves can't keep up with Samus and her new upgrades. E.M.M.I.-02SM's Central Unit is a tense struggle due to Samus having only a few energy and missile tanks, but E.M.M.I.-05IM and E.M.M.I.-06WB's Central Units can each be instantly taken out in just two hits of the Shinespark (or, in the latter's unarmored form, with the Screw Attack).
• Wetware CPU: Yet another supercomputer in the form of a giant brain. Being Chozo-made, they're presumably superior to less advanced imitations of the technology such as the Aurora Units and Master Brain, but they don't seem to have the dangerous intelligence of Mother Brain and MB.

Robot Chozo Soldiers

Debut: Metroid Dread

Heavily armed Chozo androids that fight Samus in the depths of ZDR.

---

• Dual Boss: One portion of Ferenia has Samus fighting a regular and a gold-plated Robot Chozo Soldier at once. Burenia features a fight against two gold-plated ones.
• Gold-Colored Superiority: Robot Chozo Soldiers come in black and gold-plated varieties; the gold ones are slightly tougher.
• Hero Killer: The first one Samus faces kills Quiet Robe on Raven Beak's orders just after they have given her the chance to escape ZDR without having to destroy the rest of the E.M.M.I.
• Laser Blade: They're armed with "electromagnetic blades" that allow them to slash Samus during their charge attacks.
• Mecha-Mooks: A robotic variant of the flesh and blood Chozo Soldiers.
• Plasma Cannon: They're equipped with an Arm Cannon not much different from Samus', firing vaguely electrical-looking shots from it.
• Recurring Boss: Samus has a total of 4 encounters with those things, the first two against individual units and the latter two against duos.
• Replacement Goldfish: As all the non-robotic Chozo Soldiers were infected by the X Parasites, the Robot Chozo Soldiers seem to have been built by Raven Beak to fill the gap in his army.

Experiment No. Z-57

A giant, reptilian spider-like bioweapon that was developed and experimented by the Mawkin in the Dairon region of ZDR. Its tropes can be found here.
