First Appearance: "Plastique" (The Flash 1x5)
Appearances: The Flash | Legends of Tomorrow
A gorilla who lived in Star Labs under Thawne's care prior to the accelerator malfunction. General Eiling wanted to use him in mind control experiments, but Thawne was adamant that any such test were to cease as long as Grodd was under his care. He disappeared following the night of the accident.
Grodd quickly established himself as one of Barry's feared foes, but also one to be pitied. He would be banished to Gorilla City on Earth-2 as an act of mercy, but Grodd was too far gone to react kindly to his exile. He later made his way back to Earth-1 and after another battle with Barry, ended up in A.R.G.U.S. custody.
But after the Legends broke time, Grodd ended up in the Vietnam War trying to turn the conflict into the catalyst for World War III, which quickly gained the attention of the recently resurrected Damien Darhk.
After a brief stint as the brutal enforcer of the Cult of Mallus, he was put back into A.R.G.U.S. custody, but escaped due to his powers evolving, only being defeated after a hard fight with the recently redeemed King Shark.
He was then put back into A.R.G.U.S. custody under even tighter surveillance due to his telepathic powers constantly growing.
Post-Crisis, he has come to regret his former deeds and eventually leaves on friendly terms with Barry.
- A God Am I: By the time he shows up in Season Three of Legends, Grodd has developed full-blown megalomania, referring to himself in the third person and trying to set off World War III so that he can rule over whoever survives, going so far as to describe this goal as "one nation under Grodd".
- Adaptational Heroism: Comics Grodd is a murderous overlord and sociopath with a desire to wipe out all of humanity. This version, while still a killer that hates humans, actually has a somewhat valid reason to be the way he is, and does seem to have a soft spot for some people that treat him nicely, such as Caitlin and Eobard Thawne. However, by "Attack on Gorilla City", he's much closer to his comics counterpart, to the point that Caitlin gives up on him ever being redeemed. By his first appearance in Season Three of Legends of Tomorrow, he's basically all the way there, wanting to destroy humanity by any means he can. However, even at this point he remains sympathetic to a degree, as he still laments his personal tragedy. Amaya is able to empathize with him and nearly succeeds in talking him down, when Mick and his father storm the camp at the worst possible time, leading to Grodd feeling betrayed and justified in his hatred. As of Season 6, Grodd has pulled a HeelFace Turn and is back to being more heroic than his comic counterpart.
- Adaptational Wimp: ONLY in comparison to some of the characters in Gorilla City. Whereas in most other incarnations, Grodd will almost always pose a massive threat to Solovar to the point where Grodd either overpowers Solovar or Solovar will be forced to call upon other heroes for help in defeating Grodd, this incarnation of Grodd is nowhere near as strong as Solovar, to the point where he gets manhandled by the albino gorilla and outright admits to Team Flash that he can't defeat Solovar in a fair fight. Also a justified trope in that Grodd has spent much of his life as a test subject in a cage for STAR Labs while Solovar has had a lifetime in Gorilla City to hone his powers, strength, leadership abilities, and gladiator skills.
- Unlike his comic-book counterpart, his repertoire of Psychic Powers does not include telekinesis, at least not yet.
- Always a Bigger Fish: On the receiving end. King Shark, who towers over him, defeats him during King Shark vs. Gorilla Grodd.
- Amplifier Artifact: During King Shark vs. Gorilla Grodd, he gets his iconic crown, which amplifies his telepathic abilities. Even after it is already taken from him, his powers continue to grow, which forces A.R.G.U.S. to put him into a coma to further detain him.
- Androcles' Lion: An evil example; Grodd seems to have a soft spot for those who treated him nicely (namely, Eobard and Caitlin).
- And I Must Scream: He ends up in a medically-induced coma under even tighter guard than before.
- Animal Testing: Eiling wanted to involve him with mind-control experiments, along with other gene therapies for the purpose of making Super Soldiers.
- Answers to the Name of God:Not God. Grodd.
- Arch-Enemy: The Flash's fourth most persistent enemy after Captain Cold, Zoom, and the Reverse-Flash. The Flash is the one enemy Grodd never wishes to control, who he is never willing to reason with, and wants to destroy at all costs. At least until Season 6, where Grodd finally pulls a HeelFace Turn and an Enemy Mine with The Flash, putting them as Friendly Enemies.
- Being Evil Sucks: He did not find satisfaction when trying to carry over his attacks and he realizes that he actually didn't want power.
- Berserk Button: Don't offer him a banana. Or impersonate his "father".
- Because You Were Nice to Me: He is very fond of Caitlin, but even then he still kidnaps her for his own needs.Caitlin. Good.
- Breakout Villain: Popular enough to not only survive every encounter with the Flash, but to also star in Legends of Tomorrow. It's now considered the norm for him to return at least Once a Season.
- The Brute: In Legends of Tomorrow, he becomes the personal attack dog for the Cult of Mallus, sent out whenever wide scale destruction is required.
- Celebrity Paradox: The Marvel Cinematic Universe is acknowledged to exist in this universe. His voice-actor voices Stone in Daredevil (2015).
- The Chessmaster: In "Attack on Gorilla City", he plays everyone for chumps, and even though he catches a brief Idiot Ball, he has a backup plan. As he himself says, "Father" taught him well.
- The Comically Serious: His only funny moment thus far involves his dislike of bananas.
- Curb-Stomp Battle: Delivers several to Barry over the course of "Grodd Lives." Ultimately, Barry could not take him down with his own strength and had to goad him into getting hit by a train instead.
- Dark Is Evil: Grodd is covered with dark fur and is a villainous Killer Gorilla.
- Demoted to Dragon: In Season Three of "Legends" where he's recruited into the Cult of Mallus as their brute.
- Does Not Like Spam: Like his comic counterpart, Grodd ironically hates bananas.
- Doesn't Like Guns: He throws Joe's gun away, since "Father" doesn't like them.
- The Dog Bites Back: Eiling really shouldn't have performed all those experiments (and more) on him.
- The Dragon: He's effectively this to Eobard, whom he is loyal to and refers to as "Father".
- The Dreaded: After their initial battle, he becomes this to Team Flash.
- Easter Egg: The first sign of his existence is a view of his destroyed cage in the pilot labeled with his name, which DC fans would pick up on but non-comics people would just overlook.
- Enemy Mine:
- In Season Three, Grodd tricks Team Flash into helping him defeat Solovar in combat which was a ruse to allow Grodd to take control over his army.
- In Season Six, Grodd once again comes to The Flash for help, only this time he has genuinely changed and the two of them join forces to defeat Solovar in a Journey to the Center of the Mind where they attempt to escape the mental prison.
- Establishing Character Moment: His attack on the sewer workers seems to have been put in just so we wouldn't have any doubt that he's one of the bad guys, as his revenge on Eiling is quite easy to root for.
- Even Evil Has Loved Ones: He refers to Eobard as "Father".
- Evil Sounds Deep: The explosion gave him the ability to speak telepathically, with quite an intimidating voice.
- Fantastic Racism: While he does have a Freudian Excuse for it, Grodd's hatred for humanity becomes more and more extreme every time he appears. By the time he appears on Legends of Tomorrow, he's reached the point that he sees humans as completely inferior to him and wants to rule over them. When he finds out about the Waverider, he even tries to hijack it so he can travel back in time and prevent humans from ever existing.
- Freudian Excuse: Unlike his comic self, he actually has a semi-decent reason for disliking humans, namely he suffered cruel testing and abuse from General Eiling.
- Fusion Dance: In "Grodd Friended Me" when Barry and Grodd team up in the mindscape, Barry's merges with Grodd in a similar way to Firestorm. This grants Grodd the powers of a speedster which he uses to defeat Solovar.
- Genius Bruiser: While he's not quite at the genius level when Barry first meets him, as the gradually improving calculations scrawled on the walls of his lair show, he's definitely getting there. As of "Attack on Gorilla City", he's officially gotten there.
- Gone Horribly Right: Eiling and his scientists wanted a gorilla capable of mental powers. It not only worked, but he's also grown a lot stronger and immeasurably smarter ...and he hates Eiling so much that he turned him into a human puppet for three months.
- HeelFace Turn: In Season 6. Months of being left alone with his thoughts in an artificial coma had him realize the wrongness of his actions. After some hesitation, Flash helps him out of it and he is allowed to return to Gorilla City, the only place where he ever felt he truly belonged.
- Hulk Speak: His speech is noticeably brief, as he is still learning English. Unlike most cases of this trope, however, he's far from stupid. His later appearances have him speaking just fine, but still prefers using Third-Person Person speech.
- I Just Want to Have Friends: In his second appearance he kidnaps Caitlin so he can recreate the Particle Accelerator so there will be more gorillas like him that he can have friends. Team Flash decides to send him to Gorilla City on Earth-2 instead; unfortunately he doesn't like it as he can't stand not being the alpha.
- The Juggernaut: Grodd is all but unstoppable. Nothing Barry threw at him was enough to take him down, and Team Flash was forced to send him to another Earth in order to stop him.
- Kick the Son of a Bitch: Eiling treated him horribly while trapped in a cage, but now Grodd returns the favor by torturing him.
- Killer Gorilla: Grodd is well known in the DC universe as a Knight of Cerebus; it's safe to say that he may as well be on his way to being one here when he finally shows his face. Some poor sewer workers find that out the hard way.
- Knight of Cerebus: While not quite as intimidating as the Reverse-Flash or Zoom, the humor plummets any time he's onscreen. He manages to seriously Break the Badass and leave Joe a whimpering wreck, something that even Mark Mardon was incapable of doing, and is the only combatant that Flash can't even hope to harm.
- Kung-Fu Wizard: In a sense. He's an extremely physically capable Lightning Bruiser that can also use telepathic warfare against his enemies.
- Lightning Bruiser: Not only is he strong enough to knock Barry out with one punch, he's fast enough to rush down anyone in his lair and even take the fastest person in the world by surprise, appearing as a blur during so. Though if you watch carefully, it's clear that some of that is watching his opponent and picking exactly the right moment to strike.
- Mind Control: Thanks to his telepathy, he can take control of the minds of others, as he does with Gypsy in "Attack on Central City".
- Mind Rape: Several times, he shows Barry his disturbing memories while under Eiling's "care".
- Neck Lift: Does this to Barry to show how strong he is...and follows it up by putting Barry right through a concrete wall.
- Noodle Incident: He allegedly destroyed the Great Wall of China offscreen as shown in "Beebo the God of War".
- Nothing Is Scarier: Grodd is entirely CGI, and therefore one of the most expensive villains to bring to the show. That said, his Mind Control has an impressive range, and anyone unprepared for meeting him is likely Killed Offscreen.
- Obviously Evil: A hulking brute who speaks in a deep, menacing voice. Even aside from being a Killer Gorilla, Grodd is clearly not one of the good guys.
- Once a Season: Since the first season of The Flash, he has shown up at least once (sometimes more) in each season of the Arrowverse; usually on his debut show, but in the 2017-2018 season he instead showed up on Legends of Tomorrow.
- Out-of-Character Alert: After kidnapping Caitlin, Dr. Wells from Earth-2 pretends to be Reverse Flash to get Grodd to release her. The problem is that he said "please". According to Grodd, his "father" never asks, he takes.
- Out of Focus: Despite being on the Cult of Mallus, Grodd is used sparingly given he's a CG creation. After Darhk saves him from dying, and the Legends don't face him after his recruitment. He's seen in an ancient illustration destroying the Great Wall of China, and he then makes a cameo in "No Country for Old Dads" in a video chat between Ava and Director Bennett, which ends when Grodd murders Bennett! The Legends don't actually fight him again until "Guest Starring John Noble", where he's taken out rather easily, first by Ray's shrink tech and then by Nate wielding the Earth Totem.
- The Paranoiac: Grodd is traumatised from his mistreatment at the hands of General Eiling and this leads to him becoming a Control Freak who wants power over everyone so that he can't be hurt again, which in turn makes him suspicious and cynical of anyone or anything that preaches softness or sentiment as that invites him and his underlings to be vulnerable and therefore weak. He wants revenge on everyone who ever made him feel weak or humiliated- naturally including heroes like the Flash- and his introduction to Team Flash (through Eiling via telepathy) was the raw and primitive "I am Grodd- Fear me!", which set the tone of the character to come: a villain whose ultimate desire is that everyone fears him too much to ever dare hurt him again.
- Pet the Dog: He continues to have a soft spot for Caitlin, who was also kind to him at the lab. However, he seems to abandon this in "Attack on Gorilla City", wanting her to die along with Barry and the others.
- Pragmatic Adaptation: Making him a Talking Animal would be difficult not to render silly in live action, so instead his voice is telepathic.
- Psychological Horror: Even when he isn't showing his face onscreen, he can still exert a terrifying presence using his Mind Control telepathy. Particularly unsettling in "Attack on Central City" where he tries to make Joe West perform a Psychic-Assisted Suicide.
- Red Eyes, Take Warning: His irises are always blood red, which only makes him creepier.
- Ripple Effect-Proof Memory: He is able to remember how things were before the Crisis.
- Rogues Gallery Transplant: After being a major recurring villain on The Flash for three seasons, he's transferred to Legends in Season Three as a member of the Cult of Mallus.
- Room Full of Crazy: He's covered the walls of the sewer tunnel he's been hiding in with his name. The drawings get more advanced (and creepy) as his intelligence grows.
- Sewer Gator: He'd been hiding in the sewers ever since he escaped.
- Something Only They Would Say: Whenever Grodd has someone under his Mind Control, the telltale clues are the person speaking in a very rigid and gruff voice, as well as referring to Barry exclusively as "Flash" even when he's unmasked and in the company of friends.
- The Starscream: On Earth-2, he desperately wants to usurp Gorilla City's leadership from Solovar. So much that he orchestrated events that would have Team Flash beat Solovar for him.
- Superpower Lottery: All of the meta-humans to appear on the show in the first season each have a single superpower. By comparison, Grodd has Super Strength and Super Toughness (even when considering the fact that gorillas are naturally stronger than humans), Psychic Powers, and is implied to be gradually getting Super Intelligence as well.
- Super Toughness: Not only is Grodd super tough by human standards, he's super tough even by gorilla standards. He's able to Punch Catch Barry's supersonic punch, and is so resilient that Barry's normal super-speed punches don't even seem to faze him. It takes a speeding subway train to put him down, and even then, he doesn't seem to have been injured at all, just knocked away.
- Third-Person Person: He frequently refers to himself as Grodd, even after growing out of his Hulk Speak tendencies.
- Token Non-Human: The only meta-animal of The Flash's Earth-1 Rogues Gallery. He's also the only non-human member of the Cult of Mallus.
- Took a Level in Badass: As of The Flash Season 5, his powers are constantly growing.
- Took a Level in Jerkass: By the time he returns in "Attack on Gorilla City", he's more actively malicious than he was before, manipulating Team Flash into helping him engineer a coup to overthrow the city's rightful ruler. He only gets worse in Legends Season Three, becoming an Omnicidal Maniac toward humanity like his comics counterpart.
- Tragic Monster: Grodd was a sweet and gentle gorilla that had the misfortune of being a test subject for inhumane experiments on General Eiling's orders. The Particle Accelerator gave him great power but also isolated him since he's one of a kind.
- Trapped in Another World: In Season Two, Team Flash sends him to Gorilla City on Earth-2 as a means of getting him out of the way and giving him some peace; unfortunately, he sees being exiled from Earth-1 as his home being taken from him, so he decides to invade it in retaliation.
- Used to Be a Sweet Kid: In the brief times we see Grodd before the accident, he is certainly not the violent ape that he is now.
- Ventriloquist Animal: He uses his telepathic powers to talk to people, thus he does not need to vocalize or move his lips.
- Villain Forgot to Level Grind: While he utterly outmatched the Flash in early appearances, no-selling all of his attacks and even casually catching his Supersonic Punch, as of Season 6 Barry has become so powerful that he can flatten the Meta-Gorilla with a single attack.
- Villainous Friendship: An odd one with the Reverse-Flash, due to Eobard being one of the few people who treated him decently before he got his powers. He even refers to Eobard as "Father".
- Vocal Evolution: Much like Caesar in the reboot continuity of Planet of the Apes, Grodd starts out with very broken Hulk Speak, before his speech becomes more sophisticated over time. By Season 3, he pretty much speaks like a normal human.
- Whole Plot Reference: In order to tie him more closely to the shows mythology, Grodd is given a completely new origin which resembles the Planet of the Apes reboot films more than his traditional comic-book backstory, leaving out all references to Gorilla City until Earth-2 comes along.
