Heroes
Mario
Mario
- Bash Brothers: Whenever he aids another member of the team, he often fights along with Sonic.
- Big Brother Instinct: Mario cares a lot about his younger brother Luigi. In Episode 1, even though he was annoyed by how Luigi was too scared to fight Bowser with him, he gets angry after Bowser insulted him, and in the reboot, after Luigi gets knocked unconscious by a punch from Bowser, he protects him immediately when he breathes fire on him in an attempt to lure him into getting hit in his place. In Episode 8's original run, during the fight with Basilisx, this almost gets him killed, as while he was dominating the battle until Basilisx uses his own brother's petrified body against him both as a human shield and as a club, and after this, Mario can't concentrate on his enemy because he's too worried about his brother and an eventual accidental friendly fire, as messing up the timing of his attacks might cause him to hurt or kill Luigi by accident.
- Bring It: Starting off his fight with Basilisx, Mario goes into a battle-ready stance and says "let's-a go!"
- But for Me, It Was Tuesday: A rare heroic example. Mario stomped Captain Basilisx's best friend into a lava pit and used his shell to slaughter the rest, but when Basilisx informs him of what he did, Mario doesn't remember it. Although
Fridge Brilliance sets in when you realize that there are no lava pits in the room that Basilisx mentions. Mario may not remember it because it may have never happened in the first place, to say nothing of the fact that the way he describes the death is literally impossible to pull off in-context. The only true fact about his story is that there was indeed a third Koopa Troopa behind Door #2 of Bowser's Castle in Dinosaur Land. - Dual Wielding: Hammers, with the Hammer Bros. suit.
- Expy: Word of God is that he represents Goku.
- Flight: With the Cape Feather and Super Leaf.
- Heroic Mime: Played with since, unlike most of the cast, he doesn't have text boxes, he just speaks in Italian-sounding gibberish.
- Hour of Power: The Super Star power that he picks up with Sonic in the original run's episode 6.
- Jack of All Stats: Of the Five-Man Band he fits as a balance between strength, speed, agility, endurance, skill and adaptability; thus making him useful in any situation. He'll make use of his hammer when his fists alone won't do the trick, and his varied arsenal of powerups serves to counter his opponents' moveset in one way or another.
- Master of None: Without powerups that give him new abilities, he doesn't have a specific strength he can rely on against a superior opponent. When he has Mecha Sonic's attention on him, Mario can't even land a hit — Mecha's just too fast. While Sonic is fighting Mecha in Bullet Time, Mario just panics and tries not to get caught in the crossfire because there's nothing he can contribute against that kind of speed.
- Kamehame Hadoken: His charged fireballs tend to use the stance.
- Living Legend: Even Sonic, who is from an alternate universe, has heard of him!
- Nice Guy: Mario is still the same compassionate and kindhearted hero from the games and is always immediately willing to help those in need whether it’s saving the Yoshis from the Axem Rangers or helping Sonic and Shadow to stop Mecha Sonic/Metallix.
- Playing with Fire: Fire Flowers. On top of that, they seem to give some flat boost to his durability and fighting skills—which makes sense, since in most games they give him an extra hit point on top of the typical Super Mushroom.
- Fireballs: He can shoot fireballs in this mode, one of them was even able to disrupt Mecha Sonic's aim.
- Power Glows: Usually when he's picked up a Cape Feather or Fire Flower. Notably during the original run's episodes 2 and 6 is when both are grabbed.
- Rapid-Fire Fisticuffs: He gives Bowser his own rendition of the Hokuto Hyakuretsu Ken in the first episode of the reboot.
- Sibling Team: Can't have the Mario Bros. without Luigi.
- Speaking Simlish: Carried this trait over from the Mario & Luigi series. Not as much in the reboot, but he still doesn't get a text box.
- Super Mode: The openings in both the original and reboot show Mario getting one by virtue of the Star Spirits. He appears in gold and white with a super cape.
- Super-Speed: The Cape Feather's Flight is extremely fast. In original!Episode 2, he could even Flash Step though the air. Finding one in the Minus World allows Mario to fight Mecha Sonic one-on-one, when earlier a lack of speed was a glaring weakness.
- Supporting Protagonist: While it hasn't been shown to be the case yet, it's likely he'll be this in comparison to Luigi (considering Luigi's the Gohan expy here). He may also count as this in comparison to Sonic and Shadow, considering the latter two have a much bigger beef with Metallix (what with Metallix destroying Mobius and killing their friends).
Luigi
Luigi
- Adaptational Badass: While he still has the Lovable Coward aspects he has in canon, compared to both canon & the previous series, he's much more willing to bounce into danger for the greater good.
- Big Damn Heroes: He and Yoshi get one in the original run's episode 8. In the original run's episode 9 he uses the Tanooki suit's powers to free himself from Basilisx's attack and save Mario before he is killed.
- Cowardly Lion: Emphasis on "cowardly", but he's far from just a wuss.
- Crouching Moron, Hidden Badass: Don't let that cowardly nature fool you, when he gets serious he can be as formidable as his brother.
- Dynamic Entry: In the original run's episode 9, Hammers Basilisx in the face upon recovering to save Mario from him.
- Establishing Character Moment: Gets an amazing one in the very first episode of the remake. After spending the remainder of the episode being afraid of Bowser, once Mario is defeated and Bowser starts moving in for the kill... Luigi jumps in between Bowser and Mario, shielding his brother with his own body. For all that he is a Lovable Coward, he is fully willing to die in a desperate attempt to save his brother.
- Equippable Ally: In both Episode 6 and 8, Luigi is used as a weapon thanks to the Blue Koopa Shell and Tanooki Suit.
- Expy: Word of God is that he represents Son Gohan.
- Fastball Special: Often performs this with others, him being the projectile.
- Foreshadowing: In the original run's episode 7, after being told that in the pipe maze that they could be lost forever, the professor tells him that he was just kidding, but was being serious about the pipe maze being confusing. Then, he, Yoshi, and Shadow come across a pipe that leads into a world where its really possible to end up being lost forever.
- Grievous Harm with a Body: He often gets power-ups that incorporate his body, like the Blue Shell and the Tanooki Suit. He also uses his Green Missile.
- Heroic Mime: Played with since, unlike most of the cast, he doesn't have text boxes, he just speaks in Italian-sounding gibberish.
- Iron Butt Monkey: He's carried this trait over from the series proper. Of course, he manages to survive just about everything that ends up happening to him.
- Lovable Coward: Spends most of his time afraid of everything and anything, but will always come through when he is needed the most.
- Oh, Crap!: Gets an absolutely magnificent one in the original run's episode 6.
- Sibling Team: Can't have the Mario Bros. without Mario.
- Speaking Simlish: Just like his brother, he has this trait from the Mario & Luigi games.
- Use Your Head: Seems to use this tactic more than he’d like to comical proportions.
Yoshi
Yoshi
- Adaptational Badass: In the reboot, he's able to channel the power of a Chaos Emerald he eats and puts up a good fight against Metallix, even surprising him at some points (the beatdown was one-sided in the original one). Unfortunately, Metallix is far more brutal, and also had a Chaos Emerald within his chest chamber.
- Art Evolution: He uses Yoshi's Island sprites until the original run's episode 5. From the original run's episode 6 on he has Yoshi's Island DS sprites, while all other Yoshis keep the same.
- Badass Adorable: He's the same adorable, loyal green dinosaur from the games, and can hold his own alongside the Mario Bros., the speedster Sonic, and Shadow.
- Big Damn Heroes: He pulls one of these in the original run's Episode 8 alongside Luigi, and earlier in the original run's episode 5, knocking away Thunderfoot before he can strike Mario.
- Catch and Return: True to form, he can spit projectiles and whatever he can stuff into his mouth back to the sender.
- Curb Stomp Cushion: Against Metallix in the reboot. Even empowered with a Chaos Emerald, he still ends up on the losing end, but not without making Metallix struggle first, and having him resort to use his Chaos Emerald as well.
- Expy: Of Piccolo, by virtue that the Yoshis as a whole are expies of the Namekians.
- Fantastic Nuke: When powered up by a swallowed Chaos Emerald, his eggs pack enough energy to create giant explosions when they shatter.
- Heroic Mime: Like the Mario Bros., he doesn't have text boxes. Justified because he's a sentient animal.
- Hope Spot: When he manages to catch Mecha Sonic in an Egg. It doesn't last long.
- Made of Iron: He's introduced just so Mecha Sonic has someone to pummel, and is fighting fit by the next episode. Then you remember Yoshi can take a lot in Yoshi's Island.
- Lightning Bruiser: Yoshi is fast, strong and durable, with his tongue and eggs being excellent for long-range attacks.
- The Nose Knows: Peach suggests asking him to help find the Chaos Emeralds using his sensitive nose, and indeed he is able to easily find one.
- Overly-Long Tongue: A cornerstone of Yoshi's combat style.
- Super Mode: In his fight against Metallix in the reboot, the Chaos Emerald that Yoshi swallowed beforehand grants him a power boost. In addition to growing stronger and faster, he also gains the ability to fly and lay eggs with the destructive power of a nuke.
- Team Pet: The only member who doesn't speak coherent sentences, and a trusty animal companion of the Mario Bros.
- Throw Down the Bomblet: While channeling the power of the Chaos Emeralds, his eggs become explosives that are incredibly powerful and tough enough to plow through machine gun fire without losing momentum or detonating prematurely. He also appears to be able to control them telekinetically.
- The Unintelligible: He's a dinosaur who can only speak in Yoshi.
- Tongue Trauma: Metallix in the reboot grabs him by the tongue and utterly demolishes him while he's in the robot's grasp.
Sonic the Hedgehog
Sonic the Hedgehog
- Accidental Public Confession: While arguing with Shadow the Hedgehog shortly after Yoshi nearly being killed by Mecha Sonic, Shadow briefly mentioned Mecha Sonic. Mario overheard this and asked who Mecha Sonic was, causing Sonic to say he wished he would wait for having to explain who he is, but decides Mario needs to know.
- Adaptational Heroism: Played with. Sonic was always a hero and always one of the nicest guys around, but some of his primary traits in the games and TV shows were recklessness, thrill-seeking, and a general lack of total responsibility. In here, Sonic is much more aware of the big picture and doesn't hesitate to put his problems on hold for others, like halting the Emerald Quest to help rescue Peach from Bowser. Nothing puts things in perspective like losing your planet and friends to a walking, talking doomsday weapon.
- Catapult Nightmare: On the original run's episode 5.
- Determinator: No matter the obstacle or situation, Sonic is never the one to back down.
- Expy: Word of God is that he represents Future Trunks.
- Flight: As Super Sonic. Funnily enough Mario doesn't get this power from the same source, and Sonic has to carry him into the air.
- Fragile Speedster: Though he can take a hit like the other heroes, Sonic's more about speed than raw attack or defense. He's fast enough to fight Mecha Sonic, but doesn't have the stopping power to do much of any damage.
- High-Speed Missile Dodge: He did one in the original run's episode 7, though it's subverted immediately after: the missile hits the wall and explodes, and the explosion proves realistic enough that Sonic can't outrun it. He ends up flung forward and only recovers shortly before he hits the ground.
- Hour of Power: While he can go super using a Super Star, it doesn't last nearly as long. All he can accomplish is temporarily delaying Mecha Sonic and get the four emeralds out of his possesssion.
- Hurricane Kick: One of his many moves.
- Laughing Mad: For a short while in the original run's episode 7. Doubles as a Shout-Out to Sonic the Hedgehog 3, as the sprites used were seemingly based on the laughing sprites of Knuckles the Echidna as he appeared in the aforementioned game.
- Lightning Bruiser: In a Super Mode such as Super Sonic or Fire Sonic, he retains his blistering speed but has more offensive power which he normally lacks.
- Nice Guy: Even after all he's been through, Sonic remains polite and amiable towards Mario and company. Of course, he's still fully capable of kicking ass and taking names.
- Speed Blitz: The Light Speed Attack makes a return in episode 7.
- Super Drowning Skills: Just like in the games, Sonic sinks like a rock. Fortunately for him, Mario doesn't.
- Super Mode: The usual Super Sonic fare, acquired through absorbing a Super Star this time around. It ends up only being temporary, just long enough for him and Mario to knock Mecha Sonic out of his own super form, and prepare another attack... until it turns off and causes himt o fall.
- Playing with Fire: He is also able to utilize a Fire Flower, turning him into Fire Sonic. While he doesn't display the ability to fly, it does seemingly make him move faster, alongside giving him fire-based abilities.
- Super-Speed: Even amongst a cast where nearly every fighter can move pretty fast, Sonic is still one of the fastest characters in the series.
- Take That!: When he was 8-Bit Sonic (read: almost Classic Sonic), he made this remark.Sonic (8-Bit): What the heck? Why am I so blocky? And I've put on some weight, too! Man, this really sucks!
Shadow the Hedgehog
Shadow The Hedgehog
- Accidental Public Confession: See Sonic's.
- Adaptational Jerkass:
- His game counterpart isn't a nice person either but this series emphasizes his negative qualities to better mirror Vegeta. Justified in that Mecha Sonic murdered Rouge and Omega back on Mobius making his conflict with Mecha Sonic personal.
- In the original, Shadow saved Peach from Kamek alongside Sonic. In the reboot, he doesn't care to and only Sonic saves her.
- He protests that his and Sonic's problem is “none of their business” when Sonic decides to tell the Bros the truth. In the reboot, he says this right in front of an angry Mario and Luigi, who is practically wailing over Yoshi.
- Anti-Hero: He is much more violent and aggressive than the rest of his comrades, but still firmly on the side of good.
- Berserk Button: Never mention Maria in front of him. Ally or not he won't hesitate to kill you.
- The Big Guy: He seems to be written as the most powerful fighter of the Five-Man Band, and it shows—he's the only one able to even remotely keep up with Mecha Sonic's four-emerald Super Mode, with Mario (with his raw-power-boosting Fire Flower) managing one good hit and everyone else unable to get close.
- Bullet Time: Can pull this off with Chaos Control.
- Chekhov's Gun: Shadow mentions in the original run's episode 5 that he can sense Chaos Emerald energy from long distances when explaining his suspicions about the "emerald" lying in front of him. This might act as an explanation as to how he'll find at least one chaos emerald while Mario and the others try to rescue Peach without him. Confirmed in the the original run's episode 9 trailer, as Shadow explicitly stated that he was going to focus himself to sense the location of the sixth emerald in the desert before being ambushed by Mecha Sonic.
- Expy: Of Vegeta. Word of God didn't even need to confirm this.
- Flash Step: His Chaos Control is used for this. It has some stipulations - while he can use it freely with no Emeralds, he can only do it for short distances, and it only applies to himself. He needs at least one Emerald to cross greater distances as well as bring others with him.
- Hair-Trigger Temper: He gets rather angry easily... Unlike in the actual Sonic series. This is justified, though, as the death of his teammates made him snap.
- Heroic BSoD: It is heavily implied that Shadow's current characterization stems from the trauma of having to bear witness to Rouge and Omega, his only real friends, being slaughtered. (As can be inferred from the flashback in the original run's episode 8)
- Insistent Terminology: He quickly runs out of patience with the two Quirky Miniboss Squads making up their own names for the Chaos Emeralds.
- It's Personal: Holds a strong personal vendetta against Metallix because he murdered both Rouge and Omega.
- Jerkass: His personality is pretty much a shout out alone to Dragon Ball because of Vegeta.
- Freudian Excuse: However, it wasn't his natural personality as much as him adopting it due to the trauma of his friends, Rouge and Omega, being slaughtered by Mecha Sonic.
- Jerk with a Heart of Gold: He's not evil by any stretch. He's putting in the effort to keep innocent people (and yoshis) alive and mostly unharmed.
- Kame Hame Hadoken: His Chaos Spear attack, coalesced Chaos Energy fashioned into thrown projectiles.
- Lightning Bruiser: He's got Sonic's speed plus more attack power, and chaos powers that help with both, letting him be arguably the most powerful of the five heroes. Shadow's the one who does best in fights against Mecha Sonic, almost matching the latter's Super Mode (though Mecha Sonic wasn't fighting seriously) and blitzing him in the Minus World.
- Memento MacGuffin: Keeps Rouge's locket with him, as shown in the original run's episode 9.
- Red Eyes, Take Warning: Shadow is one of the good guys, but you definitely don't want to get in his way.
- Super-Speed: His speed is on par with Sonic's, not taking into account what he can do with Chaos Control.
- Written-In Absence: Before the reboot, Shadow was going to be absent for most of the original run’s Omega Doomship arc because he wanted to find the Chaos Emeralds himself, realizing he can't convince them to continue finding the Chaos Emeralds and leave Peach behind at Bowser's hands.
Allies
Princess Peach
Princess Peach
Ruler of the Mushroom Kingdom.
- Art Evolution: For the first six episodes of the original series, her appearance comes from Superstar Saga. Come Episode 8, she uses her artwork from Bowser's Inside Story, which is kept in the reboot.
- Chekhov's Gunman: Gives Luigi a 1-Up Mushroom before the heroes head off to Yoshi's Island. This ends up restoring Mario and saving the heroes from Mecha Sonic.
- Damsel in Distress: Both times by Bowser. In episode 1 she is held hostage by Kamek in a Sadistic Choice (though it was likely that Kamek was bluffing since it was doubtful that Bowser would want Peach as a Goomba), and later is kidnapped by Bowser in exchange for the Chaos Emeralds the heroes currently have in the original series.
- Princesses Prefer Pink: As in her series of origin, she sports her pink finery.
- Say My Name: She calls out to both Mario and Luigi in the reboot of Episode 1.
Professor E. Gadd
Professor E. Gadd
- Absent-Minded Professor: He has his moments. He thought to build a radar designed to locate the Emerald Radar should they lose it. When Sonic points out he could have just made a second Emerald Radar, E. Gadd admits that probably would have been easier.
- Ditzy Genius: As mentioned in the trope above, although he is undoubtedly a genius, he is woefully lacking in common sense.
- When the Emerald Radar is stolen by the Koopa Bros, he reveals that he created a Radar-Radar to track the Emerald Radar. Sonic questions whether it would have been simpler to build another Emerald Radar, to which the Professor immediately agrees, to everyone's chagrin.
- Expy: Of Dr. Briefs, though he doesn't actually have a daughter in this one.
- Gadgeteer Genius: An inventor extraordinaire, with notable creations such as a Game Boy that detects the unique energy signatures of the Chaos Emeralds and the Poltergust and its many, MANY different iterations.
- Mr. Exposition: Boy, does he have a lot to speak about...
- The Professor: Right there in the title.
Chief Yoshi
Chief Yoshi
- Adaptational Badass: In Yoshi's Island, Yoshi needed the help of seven other Yoshis to get Mario to safety, but here he appears to have gone all the way to Bowser's castle by himself. Also, he was never able to throw anything other than eggs, let alone a Banzai Bill, in the game either.
- Adipose Rex: He's put on a lot of weight since he last saw Mario.
- Badly Battered Babysitter: Yoshi never seemed to catch a break ever since baby Mario came crashing down on his noggin, though he regards the journey with fondness in the present day.
- Composite Character: He is the same Yoshi from Yoshi's Island, but his appearance is taken from the village leader in Paper Mario 64.
- Expy: Of Guru. Unlike him, however, Chief Yoshi is still alive and kicking.
- A Father to His Men: When Mecha Sonic is about to destroy Yoshi's Island in a giant fireball, his first course of action is to get all of his fellow Yoshis to safety. He does have trouble finding an evacuation method, but Shadow manages to get them all out via Chaos Control.
- Formerly Fit: In the flashbacks to his journey with Baby Mario, he looked no different from any other Yoshi. By the time our heroes arrive on the island, he’s ballooned up considerably.
- Greater-Scope Paragon: He was the protagonist of Super Mario World 2: Yoshi's Island, and, as such, is the one responsible for all heroic feats Mario does in the current time (since he ensured the Mario Bros. could grow up to become the heroes they were destined to be).
- Hero of Another Story: He was the protagonist of Super Mario World 2: Yoshi's Island, who escorted Baby Mario back to the stork, and Baby Luigi.
- I Remember It Like It Was Yesterday: Says it almost word for word when reminiscing his last adventure with Mario.
- Nostalgia Filter: Chief Yoshi's adventures with Baby Mario were far from enjoyable, but he still remembers them fondly in spite of that.
- Nostalgic Narrator: Looks back fondly on his older days, though what's shown in the flashback didn't look that enjoyable.
- Reasonable Authority Figure: Once he recognizes Mario, he orders his tribe to cease attacking the heroes and helps them find one of the Chaos Emeralds.
- Took a Level in Badass: Inverted: Chief Yoshi was able to go the entirety of Yoshi's Island by himself, and was strong enough to throw Banzai Bills, but by the current day, he's an Adipose Rex who's not able to defend himself from a group of Spear Guys without the help of a Chaos Emerald. It seems years of doing little more than ruling over his tribe have left him rusty in combat.
Professor Kolorado
Professor Kolorado
An archaeologist yearning for adventure. Along with his assistant Goombella, Professor Kolorado is trapped in the Minus World, left with nothing but a broken stopwatch.- Adventurer Archaeologist: Is always on the lookout for adventure. The first thing he does after being trapped in the Minus World for three months is to head on to Subcon.
- Chekhov's Gunman: The broken stopwatch he's been carrying around turns out to be the key to escaping the Minus World.
- Non-Action Guy: He can't do anything in a fight, necessitating Mario and Sonic telling him and Goombella to hide so they don't get caught in Mecha Sonic's onslaught.
Goombella
Goombella
A college student at the University of Goom, Goombella is a friend of Mario from one of his many adventures. Three months before the events of SMBZ, she and Kolorado stumbled upon a mysterious warp pipe during one of their excavations, transporting them into the Minus World.- Enemy Scan: Is pretty much a walking scouter. At one point she uses Tattle on Mecha Sonic to figure out his stats, and boy is she in for a surprise...
- No-Sell: Attempts to take on Mecha Sonic with a headbonk, which doesn't even get a reaction from him.
- Oh, Crap!: Realizes Mecha Sonic's HP, Attack and Defense are all over 9000, which is way out of her league.
- Valley Girl: She peppers her lines with the usual "like", but unlike other examples of the trope, she's well-educated.
Villains
Mecha Sonic / Metallix
Metal Sonic/Turbo Mecha Sonic/Metallix
Click here to see him as Turbo Mecha Sonic in the Original Continuity
Trying to defeat Sonic, Dr. Eggman built several robotic copies to match the hedgehog, though all of them have failed. The last in this line was Metal Sonic, built with a fierce determination to defeat Sonic that the other bots lacked. After countless failures, Metal Sonic did something drastic, and merged with all previous Sonic Robots, becoming Turbo Mecha Sonic in the original series, and Metallix in the reboot. This fusion made Metallix decide that he was through following Eggman's orders, and destroyed him along with the Death Egg, which crashed into Mobius below. This sent Metallix on a killing spree until he had all seven Chaos Emeralds which he plans to use to become a perfect being. Before he could succeed, Shadow transported the Emeralds to the Mushroom Kingdom. Metallix used Chaos Control to follow the emeralds, and will stop at nothing to retrieve them and become perfect.
- Adaptational Badass: Even when he ended up becoming the True Final Boss in Sonic Heroes, Metal Sonic has never been this much of a threat.
- Also to the Mecha Sonic from Sonic 3 & Knuckles. In the game, while Mecha Sonic was certainly persistent in trying to take down Sonic at the Sky Sanctuary, he was still no less beatable than any of Sonic's other Evil Knockoffs; Here, being a Fusion Dance off all those Evil Knockoffs, Mecha Sonic is Nigh-Invulnerable, and hands Sonic and co. their asses just about every time they encounter each other. Likewise, while the game's Mecha Sonic is invulnerable in his Golden Super Mode, it's still an unstable power-up, prompting Mecha Sonic to constantly return to the Master Emerald to recover it; SMBZ's Mecha Sonic gains his Semi-Super Mode from a mere 4 Chaos Emeralds, and only loses it when Super Sonic and Super Mario knock the Emeralds out of him.
- Adaptational Villainy: Even though Metal Sonic is certainly evil in the games, this version of him takes it up to eleven. He savagely beats up and murders everyone in his way, destroys an entire planet (and slaughters its inhabitants) and then destroys an island. The original Metal Sonic from the games hasn't done any of those things.
- In the reboot, he's even more psychopathic than he was in the original series. Where Mecha Sonic would've killed Yoshi with a laser cannon either way, Metallix decides to "reward" Yoshi for the trouble by attempting to choke him to death, and he's enjoying every last second of it.
- A God Am I: He basically flaunts this towards Axem Red in episode 6 (which, in context, doubles as a shout out to one of Broly's lines from the first movie he appeared in).Mecha Sonic: "Monster? I'm not a monster. I'M A GOD!!!!"
- A.I. Is a Crapshoot: When Metal Sonic merged with 3 other Sonic robots: Silver Sonic, the unnamed Sonic Adventure robotnote , and Archie's Mecha Sonic in the original/Mecha Sonic in the reboot. Dr. Eggman discovered him in his new form. When the doctor threatened to deactivate him, the newly formed Turbo Mecha Sonic/Metallix decided to off his now inferior master, colony dropping the Death Egg onto Mobius's surface, and eventually take the entire population of Mobius out with it.
- All Your Powers Combined: Naturally he carries over many abilities from the robots that fused to make him; Metal Sonic's ability to fly, as well as make an electrical force field and use what looked like his Maximum Overdrive move on the Koopa Bros. He can spin dash like Silver Sonic, and while the unnamed robot was never used, its design draws clear inspiration from Mechagodzilla, who could fire off missiles from his hands. Mecha Sonic doesn't get that, but a machine gun and hidden missile would fit perfectly with the idea.
- Amplifier Artifact: There is a chamber in his chest where the Chaos Emeralds can be stored, and they can be used to power himself up with them at a given moment in a fight.
- Apocalypse How: Managed to cause a Class-5 Apocalyptic scenario on Mobius by the time he managed to Chaos Control to Mario's dimension.
- Arch-Enemy: To Sonic, natch. Also to Shadow due to murdering Rouge and Omega, and shown in the intros to be Mario's.
- Arm Cannon: Mecha Sonic's arm contains one of these. He usually uses it as a machine gun (with a shotgun-racking sound effect.), but he can also fire missiles out of it (two at once, even!). He doesn't use it very often though, considering that most of his opponents are fast enough/skilled enough to avoid gunfire. Metallix is packing heat too, in the form of a gatling gun.
- Art Evolution: Between two episodes of the reboot, no less. Metallix's appearance in the first episode had his robotic quills pointing downward, much like Sonic's. The second episode smooths out the portrait and sprite, with his features more defined. This second iteration has Metallix's quills pointed upwards with the top one pointing down, much like Super Sonic's appearance in the Sonic Adventure games or Shadow's quills.
- Ax-Crazy: He's a totally psychotic, sadistic bastard who's willing to do whatever it takes to collect the Chaos Emeralds. The very first thing he does upon coming into creation is crash the Death Egg into Mobius, and after beating Yoshi senseless to claim the Chaos Emerald he found, he freely admits that even if Yoshi had given him the Emerald willingly, he would have killed him just because.
- In the reboot, after beating Yoshi to an inch of his life, and detecting the presence of Sonic and Shadow approaching, he briefly considers taking them on, until he starts talking to the Chaos Emerald as if it were alive.
- Big Bad: Of the first season, and of the entire series arguably (considering his rampage is what got the Sonic characters retreating to the Mushroom Kingdom in the first place).
- Bottomless Magazines: His arm cannon never runs out of bullets and missiles. Not only should his whole body not be able to store all of these munitions, but he shouldn't even be able to create more since he's stuck in a world that doesn't use the same weaponry as his.
- Classic Villain: A murderous psychopath out to conquer the entire omniverse.
- Composite Character: Mecha Sonic goes from a robot separate from Metal Sonic, to the result of a Fusion Dance between him and other Sonic robots. Averted in the Reboot.
- The Comically Serious: The later episodes of the original series made him this at times, thanks to the quirkiness of other characters.
- His response to the Axem Rangers doing their Scouter joke:"Just who are these idiots?"
- In episode 7, when Chaos Control doesn't work in the Minus World, he actually has a rather amusing Oh, Crap! moment as he tries it over and over again. And when Kolorado and Goombella start trying to get each other to attack him, he just dryly remarks how he's Surrounded by Idiots.
- His response to the Axem Rangers doing their Scouter joke:
- Curb-Stomp Battle: He can easily beat the ever-loving tar out of any opponent(s) unfortunate enough to cross him, by his lonesome.
- Deadpan Snarker: He demonstrates a penchant for snide remarks throughout the series, particularly when dealing with quirky characters.
- Death Glare: Metallix's default facial expression is near-perpetual Kubrick Stare, inherited from Metal Sonic. It is most prominently featured in a close-up before he proceeds to finish his fight with Yoshi.
- Despotism Justifies the Means: He only cares about acquiring the Chaos Emeralds and gaining ultimate power. He's utterly destroyed all of Mobius and Yoshi's Island in pursuit of this goal.
- Determinator: As noted by Sonic in his recalling of Mobius's fate as Metal Sonic. He will not stop at anything to achieve his goal, and may God help you if you are in his way.
- Disc-One Final Boss: According to some leaked information about the older series, he would have been this in the first out of the three planned sagas.
- The Dreaded: Scary enough to cause a Mass "Oh, Crap!" among the heroes when Shadow senses he has arrived at Yoshi's Island. Mario and Luigi in particular had never personally met him at the time. Further established in the reboot when Luigi relays to Sonic and Shadow that Yoshi has a Chaos Emerald in Episode 2. Instead of celebrating, the two hedgehogs immediately bolt it, with Sonic desperately urging the Mario Bros. to help them find Yoshi. They know exactly what's happening...
- Establishing Character Moment: His first scene shows him killing a goomba carrying the blue Chaos Emerald. A goomba who, at the time, had absolutely no clue what he was carrying, or who he was.
- Eviler than Thou: He deems nobody but himself worthy to possess the ultimate power that the Chaos Emeralds host. The Koopa Bros. and the Axem Rangers X are two groups of villains who aim to take that power for their own purposes — it takes him little time to show them exactly how they stack up.
- Evil Laugh: He usually gives a wry, quiet chuckle when things are going his way, but when he sees just how pathetically easy fighting Sonic and co. is with the power of just 4 Emeralds, he lets out an absolutely spine-chilling cackle.
- Evil Knockoff: He's the product of an amalgamation of Metal Sonic and other robotic counterparts of Sonic conceived by Eggman.
- Evil Overlord: His current goal, similar to his failed attempt back in Sonic Heroes.
- Expy: According to Word of God, he is supposed to be this series' equivalent of Cell.
- Faux Affably Evil: Can display this sometimes, especially if he's winning. This is especially prominent in episode 6, though he immediately drops it once he's lost the Chaos Emeralds.Mecha Sonic: (to Yoshi) You could have made things easier on yourself if you had just cooperated. But then again, I still would have killed you anyway.
- Final Boss: If the opening sequences are of any indication, one against him will be the Final Battle of the series.
- Fusion Dance: Turbo Mecha Sonic/Metallix is the result of Metal Sonic merging with Silver Sonic/Mecha Sonic Mk. I, the (at the time)unnamed Sonic Adventure robotnote , and Archie Comics' Mecha Sonic (for Turbo Mecha Sonic)/Mecha Sonic Mk. II (for Metallix).
- Gatling Good: Metallix's version of his Arm Cannon isn't a single-barrel machine gun like Mecha's, but a rotary cannon.
- Godhood Seeker: He aspires to acquire the ultimate power (by way of the seven Chaos Emeralds) for himself so that he can become a perfect being.
- Gone Horribly Right: Eggman created the various Sonic robots in order to have a machine that can match and surpass Sonic at his own game. Once Metal Sonic merges with the older models and becomes Metallix, he proves his superiority by doing what Sonic does best: defeating Eggman.
- Hate Sink: The atrocities he commits throughout the course of the series in the name of acquiring the ultimate power for himself, everything else in the world be damned, strips him of any redeemable qualities.
- Hero Killer: Not only directly responsible for effectively ending life on Mobius, he has personally executed the majority of the Sonic cast, presumably leaving Sonic and Shadow as the only ones left. He seems to be out to kill them too, in addition to acquiring the Chaos Emeralds. Let's not forget how he almost kills Yoshi in episode 3 and continuously attempts to off the other heroes as well.
- I Am Not Left-Handed: In the reboot, he at first fights Yoshi without tapping into the energy of the Emerald he already has, rightfully confident in his power. Even when Yoshi surprises him by doing that very thing to close the gap, it takes some time before he finally loses patience and activates his own. After that, it's clear that Yoshi never had a chance despite having an Emerald.
- Implacable Man: He's hunted those Chaos Emeralds the entire time and has taken quite a beating, but he can still kick your ass no worse than before. In fact, he escalates it every time he's fought.
- Invincible Villain: He's Nigh-Invulnerable, hands out curb-stomps like they're going out of style, and the heroes have never come close to anything resembling beating him, even on their best days. In the reboot, the only reason Yoshi lands any hits on him is because he's essentially ignoring the dinosaur. As soon as Metallix decides to take the fight seriously, Yoshi is utterly screwed.
- It's All About Me: He has nobody but himself in mind when it comes to acquiring the ultimate power, everything else in the world be damned.
- I Work Alone: He holds no loyalties to any individual or faction and works purely to acquire the ultimate power for his own selfish motives.
- Just Toying with Them: He gleefully admits that the fight he has with the gang in his Semi-Super Mode - which he was winning near-effortlessly, by the way - was still just him toying with the heroes.
- Kick the Dog: He vaporises a random Goomba all because he didn't immediately comply with Metallix's demand to hand over the Chaos Emerald he found in the Donut Plains.
- Kick Them While They Are Down: He prepares to vaporize an unconscious Yoshi (who was already badly beaten unconscious during their battle over the red Chaos Emerald), only to call off his attack and set off elsewhere after sensing Sonic's arrival. In the reboot, he tries to choke Yoshi to death, but doesn't have enough time for Yoshi to run out of oxygen when Sonic arrives.
- Killer Robot: With emphasis on "killer".
- Knight of Cerebus: While the Mario villains have their share of comedic quirks and amicable traits, Mecha Sonic/Metallix is played completely seriously with no redeeming qualities or humorous traitsnote to detract from his viciousness. Doesn't help that even the other villains (Bowser, The Axem Rangers, etc.) are disgusted by his actions.
- Lack of Empathy: He thinks nothing of the lives of those he destroys to achieve his desire for ultimate power, let alone the effects they have on their loved ones. He even thinks it’s fun when he’s about to commit mass murder against innocent lives.
- Master of All: He's got overwhelming strength, extreme durability, incredible speed and reflexes, Shadow's chaos powers, and even ranged attacks. Pick any of the heroes' specialties, and you can bet that Metallix can do all of them better at the same time, without having their weaknesses. According to Goombella's Tattle, his HP, Attack and Defense are all over 9000. In the reboot, he can match the power of a Chaos Emerald even when not harnessing one himself.
- Mythology Gag: His Reboot Name "Metallix" comes from the Sonic the Comic series of Metal Sonic Robots, who are a part of the group called "The Brotherhood of Metallix". Incidentally robots that were a part of the brotherhood were based off of the original designs of Metal Sonic and Mecha Sonic.
- Near-Villain Victory:
- He was a matter of seconds away from fully harnessing the power of all seven Chaos Emeralds, achieving his final form and becoming unstoppable with only Sonic and Shadow left to oppose him. Shadow's save at the last moment stops him, triggering the events of the series.
- If not for finding a Star and using it to retrieve Mecha's four Emeralds, the heroes would have died helplessly with Yoshi's Island. Even then, they made it with only moments to spare before the island was destroyed.
- He came extremely close to blasting the heroes to dust after leaving the Minus World, but Shadow managed to warp them away in time.
- Nigh-Invulnerable: Survived the Death Egg's collision into Mobius and its subsequent explosion. And this is him with no Chaos Emeralds. In the reboot he can tank Yoshi's Fantastic Nuke eggs with relative ease, and can even withstand being inside a large one when it detonates.
- No-Holds-Barred Beatdown: He's basically the king of this, to both the Axem Rangers and the heroes. The second episode of the reboot has a perfect example when he finally decides to actually fight seriously - even with the super endurance and strength the white Emerald gives Yoshi, Metallix still thrashes him in a brutal, merciless manner, and comes close to outright killing him!
- No-Nonsense Nemesis: On Yoshi's Island he was on a hot streak with four emeralds and decided to play with his food, leading the heroes to foil him at the last possible moment. Come the next episode, he is not playing anymore — in the Pipe Maze he takes Mario and Sonic down with similar ease, without his Super Mode. Neither of them can even land a hit except for Sonic's Lightspeed Attack, and even then that's only because Sonic timed it at just the right moment.
- No-Sell: He doesn't sell many things. In the original run's episode 6 alone, everything the heroes and villains have is thrown at him, including an ability that had previously one-shotted all the heroes, and the only things shown to affect him at all are a surprise fireball from Mario, and a Super Mode Combination Attack.
- Oh, Crap!: When Super Sonic is priming to blast him to smithereens, he's left as frozen as a deer in headlights. Unfortunately for Sonic, his power-up doesn't last long enough for him to finish the villain off.
- Omnicidal Maniac: Fusing with three other robots turned Metal Sonic into this. In fact he relishes the opportunity to kill as many people as he can. When Sonic tells him he will kill too many innocents by destroying Yoshi’s Island, he sadistically laughs and says “I know” because that’s exactly what he wants.
- Ominous Adversarial Amusement: After Yoshi belches in his face, Metallix laughs before backing away and beginning the fight by whipping out his rotary cannon.
- One-Man Army: Turbo Mecha Sonic/Metallix being by himself is enough to handle a group of multiple fighters at once, as they stand little chance against him no matter how hard they try anyway.
- Out of the Inferno: Before forcefully grabbing Yoshi by the tongue during their fight in the reboot, Metallix emerges out of the rubble, looking absolutely pissed.
- Person of Mass Destruction: He tends to obliterate things. Has an island, a Death Star expy, and an entire planet's population on his resumé.
- Pre-Asskicking One-Liner: Has a few of these throughout the series in both continuities.
- Gives an appropriately chilling one in the reboot when he decides to end the fight with Yoshi. Only a few seconds of interruption prevent it from being a Pre-Mortem One-Liner.I've let you live long enough.
- Arguably his most famous one is right after he powers up using the four Chaos Emeralds, and about to dish out a brutal takedown to the Axem Rangers, with an instance of Suddenly Voiced (recycling one of Cooler's voice clips from Dragon Ball Z: Budokai Tenkaichi 3).Mecha Sonic: I'LL CRUSH YOU!!!
- Gives an appropriately chilling one in the reboot when he decides to end the fight with Yoshi. Only a few seconds of interruption prevent it from being a Pre-Mortem One-Liner.
- Red Eyes, Take Warning: As the infamous Metal Sonic as well as Metallix in the reboot. As Turbo Mecha Sonic, it seems only whatever passes as his "whites" are red, while his "irises" are sort of orange.
- Ridiculously Human Robots: Got a similar deal here as he got back in Sonic Heroes. In fact, his design in the reboot would allow him to very nearly blend right in with the characters of the Mega Man universe, being a heavily modified Bass sprite.
- Power Copying: Like in Sonic Heroes, Metallix can copy other abilities and use them himself. In the original run, he demonstrated Chaos Control, Chaos Blast, and the Light Speed Attack.
- Sadist: While Turbo Mecha Sonic was always pretty twisted and malicious, Metallix takes this even further by relishing in his kills. The most clear example of this is the reboot's version of his fight with Yoshi; in the original, Mecha Sonic was about to immediately kill Yoshi after retrieving the Chaos Emerald, where in the reboot, Metallix decided to take his time by strangling Yoshi to death just so he could watch him die slowly.
- "Second Law" My Ass!: Once Metal Sonic became Metallix, he felt that he no longer had to obey Dr. Eggman.
- Shoulder Cannon: Metallix has a pair of deployable missile launchers that mount over each shoulder.
- Shout-Out:
- He once used Akuma's "Shun Goku Satsu" in Semi-Super Mode. Against an Axem Ranger. That poor villain...
- What's worse: That wasn't even his entire attack: Shortly afterwards, he then punched Red to the Ground, punched/grabbed Red's back from below, and then kicked him into the air before vaporizing him with a beam in a manner similar to how Goku broke Nappa's back and how Vegeta killed Nappa respectively.
- The Sphere of Destruction that he used on Yoshi's Island is very reminiscent of Frieza and his planet-killing Death Balls.
- His 7-emerald transformation in the original, Metallix, appeared to be a stylized version of Sonic 3 Mecha Sonic's head and Bass' body. In the reboot, Metallix was redesigned and became the character's new base form, replacing Turbo Mecha Sonic outright. The redesign's aesthetic resembles to varying degrees the base Metal Sonic, Neo Metal Sonic, and Bass.
- In the reboot, Metallix echoes quite a bit from Fulgore, a fellow Killer Robot.
- He once used Akuma's "Shun Goku Satsu" in Semi-Super Mode. Against an Axem Ranger. That poor villain...
- Some Kind of Force Field: Activated what appeared to be a Lightning Shield to block the Chaos Emerald-powered Breaker Beam the Axems used on him. He wasn't even the target at the time.
- The Sociopath: Mecha Sonic/Metallix is one of the biggest examples of this trope you will ever come across. He is a completely evil murderer with a massive Lack of Empathy and a delusional god complex who crosses the Moral Event Horizon with alarming regularity.
- Sore Loser: He complains about Mario and Sonic humiliating him back on Yoshi's Island and swiping all of the Chaos Emeralds he had in his possession at the time."You will pay dearly for humiliating me on that puny island I destroyed!"
- Super Mode: While his standard form can technically qualify, due to it actually being a Fusion Dance-style transformation from Metal Sonic into this form, known officially as "Turbo Mecha Sonic", he has a Semi-Super Mode with 4 Chaos Emeralds, which resembles the original Mecha Sonic's Super Mode, and if Alvin had not cancelled the series, he would have gotten an even stronger form with all 7 Chaos Emeralds that would have gone by either "Metallix" or "Master Mecha Sonic". In the reboot, "Metallix" is his new Fusion Dance-induced base form, replacing Turbo Mecha Sonic from the original, with a 7-emerald transformation being unknown at this time.
- Telescoping Robot: Either this or Rubber Man, either way, he only displays it in the original run's Minus World, seemingly to compensate for being weakened while under the curse.
- Teleport Spam: While fighting the Axem Rangers in Semi-Super Mode, he teleported at a rapid pace as he was attacking one of them. Metallix can also do this in the reboot whenever he actually taps into the power of the Chaos Emeralds, allowing him to turn the tables on Yoshi during their fight.
- There's No Kill like Overkill: His preferred method of execution. More Dakka is on the less extreme end of the spectrum. Make no mistake, if he wants you dead, he'll happily thrash the everloving daylights out of you, and won't hesitate to demolish the surroundings in the process.
- Trash Talk: Taunts Yoshi while savagely beating him up.
- The Unfettered: He'll use whatever means imaginable to obtain the ultimate power for himself, and gives no damns about destroying other lives to achieve his goal.
- Unreliable Narrator: In Sonic's nightmare he stated that he was effectively doing his job as per Dr. Eggman's programming. Taking Sonic Heroes into consideration...
- Villain of Another Story: He committed several atrocities before ever setting foot in the Mushroom Kingdom.
- With Great Power Comes Great Insanity: Him witnessing the carnage he wreaked upon the world set off his current Omnicidal Maniac personality.
- Worf Had the Flu: He did still win in the end, but Sonic and Mario can fight him more effectively in the Minus World because the dimension rendered him Super-Deformed and seemingly weakened him.
- Would Hit a Girl: Ruthlessly pummels Axem Pink along with the rest of the Axem Rangers. He also murdered Amy, Cream, and Rouge in cold blood.
- Would Hurt a Child: Ignoring for a moment that the majority of the heroic Sonic cast are teenagers, there were still a few who were younger than teen age, like Tails, Cream, and Amy Rose. No bonus points for guessing who killed them.
King Bowser
Bowser
King of the Koopas. Bowser has tried for years to conquer the Mushroom Kingdom and take Princess Peach as his bride. He has failed, time and again thanks to the Mario Bros. Recently he has learned about the Chaos Emeralds, and has rallied his army to find them and use their power to finally succeed in taking over the world and defeating his rival for good.
- Adaptational Badass: Metal Bowser, in attitude if not in capability. The form appeared in Mario Party 2, and actually was similar in power to this seriesnote , but Mario Party is silly and comical while Super Mario Bros. Z is a Shonen-inspired battle series. There isn't a layer of farce to sugar-coat the terrifying threat Metal Bowser poses.
- Arch-Enemy: Mario's, naturally.
- Art Evolution: His appearance in the earliest arc has him using his Superstar Saga spritework, resulting in somewhat Limited Animation. His reappearance later on uses his more flexible sprites from Super Princess Peach, and in the reboot he uses sprites from Bowser's Inside Story.
- Bad Boss: Bowser is portrayed as a worse boss than he is the actual video games.
- Beat Them at Their Own Game: Knowing that Mario frequently uses powerups to give him an edge in his fights, Bowser brings one of his own this time around. It proves extremely effective.
- Breaking the Fourth Wall: Done very literally with his first defeat in both versions of the show: After two unknown entities (Sonic and Shadow) knock away Kamek while he was holding Peach hostage, Mario capitalizes on the distraction and throws him off the racetrack/battlefield by the tail. Bowser is then seen being hurled away and (in a scene taken directly from the ending of Mario & Luigi: Superstar Saga) crashes into the "screen" hard enough to crack it before slipping down as if hitting glass.
- Breath Weapon: Liberally launches fireballs and streams of fire from his mouth, almost like a gatling gun.
- Chrome Champion: Metal Bowser, in the first real battle of the series. Mario has a difficult time defeating him. It takes the timely arrival of Sonic and Shadow's capsule for Mario to even stand much of a chance in the fight.
- Combat Pragmatist: Has no qualms about baiting Mario into taking a fireball by firing it at Luigi.
- Drama Queen: He throws a hissy fit while bawling his eyes out over his loss against Mario.
- Even Evil Has Standards: He did not take Yoshi's Island's destruction very well, especially when it was not under his orders.
- Expy: In the first episode (two in the original) he's effectively Frieza, with the twist that he fights and defeats the Goku analogue before Future Trunks arrives and helps stop him. After he decides that he wants to get his hands on the Chaos Emeralds, he becomes one of Commander Red.
- Gosh Dang It to Heck!: "WHAT THE DEUCE???!!!"
- Hair-Trigger Temper: When Kammy intrudes on him during his tantrum, she's promptly blasted.
- The Juggernaut: Bowser isn't much better at tagging Mario even after going Metal. He's just unstoppable, so Mario can't make him flinch, knock him off balance, or do anything about his attacks except run, while unable to do damage in return.
- Kamehame Hadouken: He does it with fire breath!
- Malicious Misnaming: Whether by accident or intent, he never calls Eggman by the right name, exclusively using names like "Yolkman" and "Eggplant".
- Mighty Glacier: He can move extremely fast while running, jumping, or rolling, but in close quarters combat he's relatively slow and clumsy. He can hardly get a hit on the smaller and more agile Mario, but whenever he does it sends Mario flying and leaves a crater on impact — and Bowser's too tough and heavy for Mario to easily do the same.
- Near-Villain Victory: Bowser comes within seconds of killing Mario twice at the start of the series, with only Sonic and Shadow's arrival stopping it.
- Nigh-Invulnerable: Metal Bowser might be the most durable thing yet seen in the series, taking every attack Mario can throw at him without blinking. Mario's charged fireballs can make four-emerald Mecha Sonic flinch, but can't hurt Metal Bowser. His toughness finally reaches its limit when Sonic and Shadow's capsule lands on him at terminal velocity, doing enough damage to shatter the powerup.
- No-Sell: Nothing Mario does can damage Metal Bowser. The direct approach just gives him Agony of the Feet, his hammer is useless, normal fireballs bounce off to no effect, and the Mario Finale kicks up a lot of dust but doesn't hurt.
- Not-So-Harmless Villain: While he is Laughably Evil, usually just wants to beat Mario and kidnap Peach, and has been defeated many times in the Mario series, that doesn't mean he isn't dangerous. Bowser's attack at the start of the series beats Mario and nearly kills him. Afterwards he teams up with Eggman, captures Peach and uses her as leverage to try and force the heroes to surrender their Chaos Emeralds, while mobilizing his army and Cool Airship to threaten the kingdom.
- Rolling Attack: He has this ability from Bowser's Inside Story, which he uses to chase Mario or just to quickly get moving after being knocked onto his back.
- Training from Hell: In preparation for his assault that kicks off the reboot, Bowser trained by powerlifting a Thwomp many times his own size. And beating up Sandbag, but that's not the "hellish" part.
- Villainous Breakdown: He suffers something like this after his defeat at Mario's hands and has a LONG tantrum extending into the original run's episode 7. In the reboot, his tantrum is omitted.
Dr. Eggman
Dr. Ivo "Eggman" Robotnik
- Adaptational Early Appearance: In the original, he first appeared in Episode 7. In this one, he appears in the second episode, and his dialogue implies he's been interacting with Bowser even before his fight with Mario.
- The Dragon: To Bowser.
- Expy: Of Dr. Gero, wherein his creation proves more dangerous than himself and betrays him.
- Face Framed in Shadow: For Episodes 7 and 8 in the original, and intro sequences. Not that it helps any, due to his distinctive silhouette. Episode 2 of the reboot makes no effort to hide his identity, fully revealing him within seconds of him showing up.
- Foreshadowing: In the original, his survival was hinted in Sonic's flashback sequence in Episode 4. Sonic and Shadow returned to the wreckage of the Death Egg to find the main control station intact and functional, plans for a dimension-hopper capsule, and the Mushroom Kingdom already in the database. Why these things would exist isn't revealed until Episode 7, when Eggman appears alive. In the reboot this foreshadowing is negated, as he shows up early in Episode 2.
- Genetic Engineering Is the New Nuke: The good doctor appears to have expanded his repertoire to biotechnology and genetic engieering rather than simply robotics. It's implied he is the mastermind behind the emotionless Super-Soldier experiment that turned Basilisx from a lowly mook to one of the deadliest soldiers in Bowser's army.
- It's Personal: Eggman notices Sonic is invading the Omega Doomship, and leaves his post to personally confront the hedgehog.
- Killed Off for Real: Assumed when the Death Egg crashed into Mobius. It didn't take.
- Mad Scientist: It wouldn't be Eggman if he wasn't this, now would it?
- Malicious Misnaming: Bowser never calls him by his actual name.
- The Man Behind the Man: He seems to be manipulating Bowser.
- Not Quite Dead: In the original. He's teamed up with Bowser, and this revelation is revealed even before Metallix's supposed origin story.
- Unwitting Instigator of Doom: He was the one who created Mecha Sonic after all.
- Sole Survivor: The only known survivor of Metallix’s rampage besides Sonic and Shadow.
- Villain Team-Up: With Bowser although he’s surprisingly a little submissive and patient in this one.
Basilisx
Basilisx
- Avenging the Villain: He claims that he is avenging his best friend after Mario killed him. It's ambiguous, however, if what Basilisx is saying about him is believable, as Mario denies recalling such an event.
- Caught Monologuing: Even when Bowser tells him to kill Mario already, he insists on relishing every last moment in rubbing his victory in Mario's face. Expectedly, this gives Tanooki Luigi time to use his suit's power to break out of his Taken for Granite state and save Mario's life at the last moment.
- Clean Cut: Cuts through Mario's hammers like they were nothing.
- Combat Pragmatist: Zigzagged. He could have just used the Stone Gaze to turn Mario to stone immediately, but he challenged Mario to a one-on-one fight instead, preferring to kill a flesh-and-blood Mario. In the actual fight, however, he has no qualms about using Poison Mushrooms to weaken his opponent or Luigi as a shield/bludgeon.
- Dirty Coward: He uses a petrified Luigi as a shield to dissuade Mario from attacking, which also allows Basilisx to easily finish off his opponent.
- Duel Boss: He forces Mario into a one-on-one, so he can experience the pleasure of killing his friend's (presumable) murderer.
- Elite Mook: He's basically a Koopatrol on steroids.
- Even Evil Has Loved Ones: He bears a personal grudge against Mario and wants him dead for killing his best friend during the events of Super Mario World.
- It's Personal: Harbors an intense grudge against Mario.
- Kiai: Utilized this during his fight with Mario at one point.
- Kill Him Already!: Bowser urges him to do this, but he's to esctatic to rub his victory in Mario's face. Unsurprisingly, this opens a window of opportunity for someone else (Luigi) to save the day, much to Bowser's chagrin.
- Mook Lieutenant: To the Koopatrolls, which Mario and co. have little to no trouble taking out en masse.
- Original Character: Doesn’t exist in the games.
- Prepare to Die: Utters one of these before fighting Mario for the first time.Basilix: I could simply turn you to stone and grind you into dust, but I would rather take delight in licking your blood off your corpse after the battle. The Underwhere awaits you!
- Red Eyes, Take Warning: One of the major differences between him and a regular Koopatrol.
- Shout-Out: His finishing move against Mario is Vega's Bloody High Claw.
- Sssssnake Talk: Even his name gets in on it. Just try saying that last bit.
- Story-Breaker Power: Can turn anybody into stone with a single glance, leaving them motionless and powerless to do anything against him. He could have killed all the heroes (minus Shadow) without any actual effort had he not wanted to choose to kill Mario fresh instead of destroying his stone statue.
- Super-Soldier: Again, he's basically a Koopatrol on steroids. You can't get any more blunt than that.
- Taken for Granite: His specialty is turning enemies to stone by staring into their eyes.
- Unreliable Narrator: Basilisx claims that Mario kicked his friend into a lava pit... but in Super Mario World, there is no lava in the corresponding room. It's been confirmed by
Word of God this was a miscalculation on their part. - Wolverine Claws: Bears these, and is very adept with them.
The Koopa Bros.
The Koopa Bros.
- Achievements in Ignorance: They inadvertently manage to tap into their stolen Emerald when using their special attack, powering it up. None of them have any idea what's happening to them even as they glow with lightning and blast off in a trail of fire, K.O.ing the heroes in one hit.
- Adaptational Badass: A large part of it is due to the Chaos Emerald's power, but even without it, they were way more of a threat than they were in the games. Individually they were only slightly tougher than normal koopa Mooks, and much weaker than Koopatrols which are cannon fodder in this series. They got even more threatening in the reboot, as they now are carrying weapons.
- Beware the Silly Ones: Totally Radical buffoons they may be, they're still surprisingly strong fighters. And with their Chaos Emerald, their special attack becomes a devastating threat that beats the heroes the first time.
- Burning Rubber: Their powered-up special attack leaves a trail of fire behind them as they rocket forward at blinding speed.
- Clothing Damage: Red's shell shatters upon Mecha Sonic's arrival on Yoshi Island, leaving him in only his underwear.
- Colour-Coded Characters: Each of the Koopa Bros. are identified by the colour of their boots, masks and shells.
- Colour-Coded for Your Convenience: In the reboot, the handle on each member's weapon shares that owner's assigned colour.
- Combination Attack: Just like in Paper Mario, they can stack up and spin. This attack is amplified with the Chaos Emerald in hand.
- Continuity Nod: Their defeat by Mario was referenced in Paper Mario, and this time, they actually have a chance to exact revenge on their earlier defeat at Mario's hands (although they attempted to have revenge on Mario late in their original game, they weren't able to get the chance because Jr. Troopa brushed them away before they could fight Mario.)
- Curb-Stomp Battle: They were on the receiving end of this in the original run's episode 6. What the three-way battle between them, the heroes, and the Axems would most likely have achieved eventually was achieved in one blow by Mecha Sonic.
- Expy: Of the Teenage Mutant Ninja Turtles. Made even more apparent in the reboot, thanks to the Koopa Bros. wielding the Ninja Turtles' signature weapons (Red uses Leonardo's katanas, Black uses Raphael's sais, Green uses Donatello's bo staff, and Yellow uses Michelangelo's nunchaku).
- Flanderization: Yellow was even more prone to doing stupid stuff than before. In the game he was originally in, while he wasn't necessarily the smartest of the brothers, he certainly had his moments of at least cleverness, as he was the only one of his brothers who actually succeeded in (albeit temporarily) capturing Mario (by creating a makeshift "?" block to use to activate a trap door below him that leads to a jail cell.
- Killed Off for Real: In the original continuity, they met their ends when Mecha atomized Yoshi's Island.
- Saying Too Much: Red silences Yellow for confessing that they acquired the Emerald Radar in the Axem Rangers' presence.
- The Leader: Red.
- The Starscream: After beating Mario, Sonic, Shadow, and Luigi due to their unintentionally activating the Chaos Emerald's powers, they considered backstabbing Bowser and calling the shots.
- Too Dumb to Live: They have their moments. Like when one of them tells the Axems about the emerald radar, or when it turns out they've been holding it upside down.
- These are all just from Yellow. The other 3 are much smarter. Of course, one should question why they let the dumb one hold the radar in the first place...
- Totally Radical: Like in the games, they speak like they're stuck in the 90's.
- The Worf Barrage: Their special attack, powered up with an Emerald, beats all the heroes in their first fight. Mecha Sonic sets his sights on them while they're using it on Yoshi's Island, and his idea of getting the Emerald from them is to plow right through the attack like it was nothing.
The Axem Rangers
The Axem Rangers X
From left-to-right: Red, Black, Green, Yellow, and Pink.
The Axem Rangers, once destroyed by Mario, have been rebuilt by their master Smithy with new bodies and power. After discovering a Chaos Emerald on Yoshi Island, the Axem Rangers enslave the population and have them mining the island to find more "amethysts of might" so that they can restore Smithy to his full power.- Always a Bigger Fish: They're the unfortunate victims of this as after putting up a damn good showing against the heroes, Mecha arrives to make it clear to them just where their place on the totem pole is.
- Back from the Dead: Axem Red says Smithy rebuilt the team to have them find new sources of power.
- Badass Creed: Furthering their parallel with the Ginyu Force, they recite their motto from Super Mario RPG in their introduction, though with some... slight changes.Red: We fight for evil!
Black: We live for disorder!
Green: We like what we do!
Yellow: We eat donuts!
Pink: We wear the trendiest clothes!
Red: We are...
All: AXEM RANGERS X! - Braggart Boss: Axem Red boasts about the power of his secret weapon to a 4-emeralds buffed Metal Sonic. It doesn't end well.
- Bullying a Dragon: Red's supreme confidence in himself and the other Axems being the big dogs in the equation fails to grasp just how much stronger Mecha is, even after his entire team is ripped to shreds.
- Came Back Strong: Were upgraded as well when revived by Smithy.
- Combination Attack: Axem Green and Black's special skill, combining into a large spinning wheel, which can cleave through stone.
- Cool Airship: The upgraded Axem Rangers come with a similarly upgraded Blade, complete with Breaker Beam. Mecha Sonic flies through it from bow to stern, blowing it out of the sky.
- Dumb Muscle: Yellow is accused by Green of being an imbecile, and has enough strength to split a mountain nearly in half.
- Entertainingly Wrong: Having no idea what a Chaos Emerald is, just knowing that an extremely powerful gemstone was suddenly found on Yoshi's Island, the Axems' best plan to get more is to dig up the island, assuming that it's from a superpowered mineral vein rather than another dimension.
- Even Evil Has Standards: Axem Red flipped out at Mecha Sonic due to not just killing his teammates, but brutalizing them.
- Expy: With where they debuted, the Axem Rangers X are the SMBZ equivalents of the Ginyu Force.
- Face Fault: Axem Yellow causes one among his team after saying they should get McGoomba's after being discovered by Mario.
- Good Old Fisticuffs: Axems Yellow and Red can fight like this too when deprived of their axes.
- Half the Man He Used to Be: The fates of Pink and Black, and a vertical variation for Yellow.
- Heart Symbol: Axem Pink has one appear in the air at the end of her special combo.
- Killed Off for Real: By the end of #6 in the original run, they're all dust. Though it was possible they could have returned given Smithy had remade them before.
- Meaningful Name: AX 'EM. Duh.
- Off with His Head!: The fate of Green. If that wasn't enough, Mecha Sonic even ups it by actually crushing Green's decapitated head with his bare hands.
- Oh, Crap!: Due to their self-believed superiority, once things start falling apart they become very prone to this. Once Mecha shows up, their screentime becomes a nonstop barrage of them attempting to kill him, failing and realizing just how deep in trouble they are.
- Shout-Out:
- "Hey Red, what does the scouter say about his power level?"
- Also, the Axem Rangers' "upgraded bodies" are that of Zero's regular form (Zero Series), Zero's Defense Form (Zero Series), A customized version of the Zero model depicting Black Zero, GutsMan.EXE, and Roll.EXE for Axems Red, Green, Black, Yellow, and Pink. Their pole-axes (except for Yellow's) are the Triple Rod sprites from the first Mega Man Zero game with the spearhead replaced with color-matched axeheads.
- The Smurfette Principle: Axem Pink is the only female member of the team.
- Spin Attack: Axem Green and Black's special again. Also, all rangers appear to be able to pull off a tornado spin attack.
- Too Dumb to Live: Even after Mecha Sonic swipes the Chaos Emerald in their possession (along with the Koopa Bros'), the Rangers start a fight with him. A powered up Mecha Sonic demonstrates in seconds why it's a terrible idea to mess with him.
- Wave-Motion Gun: Axem Red's secret weapon (which he seems to pull out of hammerspace), not to mention the Blade's Breaker Beam.
- The Worf Barrage: Axem Red's secret weapon, again and the Breaker Beam, again. Both times toward Mecha Sonic.
- Wrecked Weapon: The first indication of Mecha Sonic's overwhelming power is when Yellow hits an unmoving (not even transformed) Mecha with his axe, and the only effect is the axe just falling apart.
- "X" Makes Anything Cool: Their team name is complemented with an "X" to demonstrate their newfound power after their restoration.
- You Monster!: Red says this to Mecha Sonic after he killed every other Axem Ranger, to which Mecha responds:Mecha Sonic: Monster? I'm not a monster. I'M A GOD.
Wario and Waluigi
Wario and Waluigi
- Adaptational Badass: The only instance of them antagonizing the Mario Bros in the original series directly was the first episode, and they became joke characters afterwards. The first reboot episode replaced their brief race into an actual fight and the following episode featured them fighting Luigi and Yoshi directly. They at least qualify as an obstacle, if not a serious threat this time around.
- Acrofatic: Wario runs pretty fast despite his huge girth.
- Art Evolution: Up until Episode 6 of the original series, Wario was depicted with his sprites from Wario Land 4. From that point on, he instead uses custom sprites in the style of Superstar Saga, to match the Mario Bros. and Waluigi.
- Bumbling Henchmen Duo: In the grand scheme of things, they're not a real threat.
- Butt-Monkey: The duo are prone to getting smacked around for laughs, but Waluigi has it especially bad, probably more than Luigi. Much of his abuse is brought on by Wario.
- Combat Pragmatist: Being Mario's Evil Counterpart, Wario does not shy away from fighting dirty, figuratively or literally. The first episode of the reboot sees him have Waluigi distract Mario before hitting him the back so Waluigi can get some decent hits in.
- Combination Attack: In the reboot, Wario has Waluigi light one of his farts on fire, making for a powerful blast. This is a Shout-Out to one of Alvin's contributions to the Beat Up Sandbag collab, where Wario and Waluigi did the same thing.
- Cool Car: The aptly-named Wario Car, the one that first appeared in Wario Land 4. The two use it to race against the Mario Bros. in the original, and as a getaway vehicle in the reboot.
- Extreme Omnivore: Wario pulls out a whiteboard, and after a short run-through of their plan to steal the Chaos Emeralds, devours it.
- Expy: With them being a Goldfish Poop Gang who are searching for the Chaos Emeralds out of greed and nothing else, they're dead ringers for the Pilaf Gang.
- Fat and Skinny: They're the Mario Brothers, with their physical traits exaggerated. Wario being bigger and fatter, Waluigi being taller and lankier.
- Fartillery: Wario will gladly unleash his Wario Waft to blast his target away or disorient them. If a Fire Flower is in the way, expect the equivalent of a nuclear blast!
- Gasshole: Goes without saying that Wario is the one of the duo who is this. He burps after eating and occasionally uses his farts as part of an attack.
- Goldfish Poop Gang: Most of the other antagonists are actual threats. These guys... well, they'd be lucky to even get in the heroes' way successfully.
- Greed: Their goal in the series is to steal the Chaos Emeralds and sell them for a high price.
- Involuntary Shapeshifting: Wario will use Waluigi for whatever he needs. Including a swimming ring in the original run and a baseball bat in the reboot.
- Jaw Drop: Both are left speechless when Mario is revealed to have survived their Combination Attack, thanks to Luigi throwing him a Starman.
- Man Bites Man: Wario tries repeatedly in the reboot to bite Mario in half.
- Mythology Gag: Wario "summons" Waluigi (who was already sort of standing in Wario's corner outside the battlefield until that instant) with an Assist Trophy, just like what might happen in Super Smash Bros.. The whole situation is promptly lampshaded by their reactions to the item's immediate effect.
- Pre-Asskicking One-Liner: "Have a rotten day!" Said before Wario lights Mario on fire with his fart.
- Shoo Out the Clowns: In episode 1 of the reboot, they're propelled out of the story when a giant Bob-omb blows up in the middle of the arena, making way for Mario's Arch-Nemesis, Bowser. They get blasted off again courtesy of Metallix' missiles in the next episode before the brutal fight between him and Yoshi.
- Toilet Humor: Wario's bread and butter.
- This Is Gonna Suck: Wario lets out a worrisome "Oh no..." just as the giant Bob-omb lights its fuse.
- Throw Down the Bomblet: Waluigi's arsenal includes a Hammerspace supply of Bob-ombs, which he uses in Episode 7 of the original and Episode 2 of the reboot.
- Unknown Rival: Although they too are seeking the Chaos Emeralds, our heroes are unaware of them the entire time. This is averted in the reboot where in Episode 2, they directly get into a scuffle with Luigi and Yoshi over a Chaos Emerald they all found.
