    Knuckles the Echidna 
Voiced by: Nobutoshi Canna (JP), Dan Green (EN)

Sonic's friendly rival, Knuckles is the guardian of Angel Island and the Master Emerald. Completely focused on his duty to guard the Master Emerald, Knuckles has been wandering to find it, and keeps to himself. He is short-tempered and easy on forgiveness, but he makes up for it with his courage and fists.

  • Adorkable: He tends to be shy and awkward around girls.
  • Aloof Ally: In Season 1. however he grew more attached to the group in later episodes.
  • Anti-Heroines Want Redheads: Rouge has a crush on him. Despite it being unknown whether he truly likes her or not, he does have his moments where he is caring for her.
  • Battle Couple: With Rouge.
  • Badass: One of the biggest examples of the show.
  • Beware the Nice Ones: He's much more easy going and humble when he's in a good mood, but NEVER hurt innocents in front of him, steal the Master Emerald or make him angry.
  • Belligerent Sexual Tension: With Rouge.
  • Big Damn Heroes: His introduction in episode 1 when he saved Tails and Amy. Also when he saved Tails in episode 10.
  • Big "Shut Up!": To Sonic in "Cracking Knuckles".
  • Butt Monkey: Prone to slapstick, and often the butt of gags from the rest of the team (often owed to his solitude). This is downplayed in the comics, though he's still kinda bumbling in tone.
  • Character Development: Knuckles at first was the only one who did not have the time to joke around. In the later episodes, however he did crack a few jokes as well as some friendly teasing.
  • The Cassandra: Knuckles seems to have to deal with being this in most episodes.
  • The Comically Serious
  • Commander Contrarian: Unlike the others, who took enjoyment settling down and learning about Earth, Knuckles was vehement on returning to their home world as soon as possible, but since he's the guardian of the Master Emerald, he doesnt really have a choice but rather HAS to go back to not risk anything happening to Angel Island.
  • Cute Little Fangs
  • Determinator
  • Depending on the Writer: Knuckles is portrayed the defining example of Badass in most episodes such as episode 1, episode 17, episode 36 and episode 72. However, sometimes he gets different roles such as the Butt Monkey just for humor's sake.
  • Dreadlock Rasta
  • Defeat Means Respect: He respected Emerl with a handshake and complemented him after being defeated by him.
  • Fiery Redhead
  • Friendly Rivalry: With Sonic, as usually.
  • Friendship Denial: In a couple of episodes of the first season, he loathes the idea of being Sonic's friend. Justified in that the hedgehog's snarky attitude and reckless behavior seriously got in his nerves. Plus, he has better things to do as the guardian of the Master Emerald.
  • Good Is Not Soft: Knuckles is nice to those who are the same in return, but never try to hurt an innocent or steal an emerald in front of him.
  • Good Is Not Nice: He is prone to punching someone instead of greeting them.
  • Green-Eyed Monster: Jealous of Sonic's freedom, popularity, and carefree nature.
  • Grumpy Bear
  • Gullible Lemmings: Both Eggman and his own friends exploit this at times.
  • Hardcore: Knuckles is probably the most hardcore of the cast
  • Hair-Trigger Temper
  • Horrible Judge of Character: He's constantly tricked by Eggman, and it's lampshaded every time.
  • Hot-Blooded: Knows exactly when to pick a fight with people who push his buttons.
  • Ineffectual Loner: At first he detached himself from the group, but he came around.
  • Insane Forgiveness. Knuckles believes in the good of people, therefore he will always forgive a villain no matter what bad things they do.
  • Jerk with a Heart of Gold
  • The Lancer
  • Large Ham: Duh. Look who voices him.
  • Made of Iron / The Stoic: He is able to win a fight by himself after repetively getting stomped by a giant alien with metallic body armor and being hit by thunder.
    • Stoic Woobie: Despite always keeping things to himself and never shows sadness to the outside, Knuckles's status as being the last of his kind still keeps him depressed, and the other team members ganging up on him and treating him like a punching bag does not make it any better.
  • Married to the Job: Spent much of the 1st season thinking about the Master Emerald and Angel Island.
  • Misunderstood Loner With A Heartof Gold. Knuckles seems to be the most unthanked of the cast. Being mistaken for Jerkass by other the other team mates for thinking different and prefering to do things alone.
  • Mysterious Past: The last of his kind, that's all he knows.
  • Nobody Calls Me Chicken: A Running Gag was for Sonic and co. to batter Knuckles' ego whenever he didn't want to do what they wanted to.
  • No Respect Guy
  • One-Man Army: In Episode 36, He Beated a bunch of Eggman's robots who mistook him as Sonic. Even before Sonic came to help, Knuckles still defeated twice as many robots at once.
  • Only Sane Man: Along with Tails.
  • Perpetual Frowner: Most of the time anyway.
  • Power Fist
  • Proud Warrior Race Guy
  • Purple Eyes
  • Redheaded Hero
  • Pint-Sized Powerhouse
  • Save the Villain: In episode 37, he saved Rouge from falling, though they were fighting. He also tried to save Yellow Zelkova from falling down to the lava after a rough fight.
  • Sensitive Guy and Manly Man: The Manly Man to Sonic's Sensitive Guy.
  • Selfless Wish: Knuckles wishes to go back to the Master Emerald so that Angel Island won't fall into the ocean.
  • Super Strength
  • Trademark Favorite Food: Leek buns.
  • Vitriolic Best Buds: With a lot of the cast due to the differences of personalities, but especially with Sonic and Amy.
  • Walking the Earth: Before joining Sonic and Co., Knuckles traveled around on his own to find his way back home.
  • The Worf Effect: The most likely of the heroes to fall to this.
  • Underestimating Badassery: He gets underestimated and mocked alot, but in the end of the day, he's actually the bravest and toughest fighter of the group.
    • In episode 17, when he walked into the bar, a group of guys wanted to start a fight with him for asking the bartender a question, right when he beated one of them with no problem, Mr. Lee Yang broke in to tell them that they wouldnt be able to beat him.
  • Vigilante Man: Knuckles takes the law into his own hands. No villains around him should try anything.
  • Would Hit a Girl: His philosophy is to not attack the weak - anyone who can stand up to him, regardless of gender, is fair game.
  • Wouldn't Hurt a Child: At the tournament, he refuses to lay a hand on Chris, despite Chris wanting to fight.
  • You Wouldn't Like Me When I'm Angry. You really shouldn't try to piss him off. In fact, he's a loyal and caring friend but getting on his bad side is a suggest that you may end up like a fish out of the water.

    Amy Rose 
Voiced by: Taeko Kawata (JP), Lisa Ortiz (EN)

Sonic's self-proclaimed love interest, Amy is an optimistic, strong-willed girl who has a long-standing crush on Sonic and wants to be his girlfriend.

    Bokkun 
Voiced by: Yumiko Kobayashi (JP), Andrew Rannells (EN)

    E-Series 
  • Arrogant Kung Fu Girl: E-91 Lady Ninja, from what brief sentience she shows.
  • Attack of the 50-Foot Whatever: E-99 Egg Emperor.
  • Dub Name Change: E-99 Egg Emperor is changed to the Eggsterminator in the dub due to the boss of the same name from 'Sonic Heroes, which it looks nothing like
  • Gratuitous Greek: Joked about "As far as their names go, it's all Greek to me".
  • The Fool: Pretty much E-77 Lucky's premise.
  • Knight of Cerebus: E-99, the fight with being one of the few moments in the series where Sonic dying is presented as possibility.
  • Lightning Bruiser: E-99, with the Chaos Emeralds powering it (we don't see it fight much without them). It moves so fast that not even Sonic can keep up with it.
  • Humongous Mecha: Some of them are big enough to qualify.
  • Minion with an F in Evil: Some of the E-Series are more loyal drones than evil, some such as Gamma and Lucky turn out to be rather benevolent when not under Eggman's control.
  • Monster of the Week: The recurring plotline of the first season was for Eggman to send in one of his robots to cause chaos each episode.
  • Spared by the Adaptation: E-100 Alpha "ZERO" is not destroyed in the anime, he is last seen comically knocked out by Amy.

    E- 102 Gamma 
Voiced by: Naoki Imamura (JP), Andrew Rannells (EN)
  • Badass: One of the Best examples.
  • Co Dragon: Briefly acts as one alongside Chaos to Eggman, following his brothers "demotion".
  • Gender Bender / She's a Man in Japan: For unknown reasons Gamma was referred to as female in the Dutch dub, in so far that Amy solely referred to Gamma as 'Miss Robot'. The gender change may have been based on Gamma's helium pitched voice in the English dub. It's incredibly bizarre for anyone who actually played Sonic Adventure.
  • Heel-Face Turn
  • Heroic Sacrifice
  • Minion with an F in Evil: Gamma is a robot, so most of "evil" actions owe to following Eggman's orders. As he gains emotions, he becomes increasingly empathetic and ultimately turns sides.
  • Obi-Wan Moment: Given he's a robot, it's mostly a given. However he specifically states his happiness about Beta's bird coming out safe before shutting down in the original Japanese edit.
    E-102 Gamma: Gamma; Mission Complete...
  • Robo Speak: In both dubs, in contrast to his Machine Monotone in the games versions. Oddly the English dub also gives him a helium pitch synthetic.

    Dark Oak 
Voiced by: Joji Nakata (JP), Jonathan Todd Ross (EN)

  • Aliens Are Bastards
  • Authority Equals Ass Kicking: This guy BEAT Super Sonic (likely very badly considering he only had some slight superficial damage while Sonic was exhausted), who was presented as invincible in the first two seasons.
  • Big Bad: Of Season 3.
  • The Chessmaster: His smooth plans involved using Cosmo as a spy to have all seven Chaos Emeralds gathered for him so he could bring them together for the Forestation process.
  • Cyber Cyclops
  • Drunk with Power
  • End of the World as We Know It: He removed planets' Egg, allowing the planets to wither and die.
  • Even Evil Has Loved Ones
  • Knight of Cerebus: The show gets ALOT more serious when he takes over as the Big Bad.
  • Knight Templar
  • Love Redeems
  • Cosmo, I may be your father: Implied to be Cosmo's father.
  • Manipulative Bastard: We learn in "Shadow's Arrival / The Cosmo Conspiracy" that he secretly manipulated Cosmo into using Sonic and his friends to gather all of the Chaos Emeralds for him. In "The Lost Planet / Eye Spy" after that, it is revealed that Dark Oak had been using a device implanted within her head to make her his unwilling spy the whole time.
  • Orcus on His Throne: He sends Metarex out to kill Sonic, and besides that mostly just sits around and does nothing. Especially jarring given that it turns that he could have easily found and killed him whenever he wanted to.
  • Taking You with Me: After Super Sonic and Super Shadow destroy the shell of the Final Nova's planet form, he decides to try his hand at attempting to OBLITERATE the ENTIRE universe with himself in his final moments.
    Dark Oak: Foolish hedgehogs. With the help of the Planet Egg, you were able to stop my plans to transform the universe. But you can never win this battle... If the Metarex cannot rule the galaxy, then we will destroy it! Muahahahahahah...!
  • Tragic Villain
  • We Can Rule Together: He uses this with Sonic in the fourth-to-last episode before devouring him for deciding he would rather they get rid of him than him join the Metarex and let them take over the galaxy without a fight.
  • We Have Reserves: The Metarex seem to adopt this doctrine as a whole, and Dark Oak invokes this trope when Sonic and he meet again after their battle
    • "For each one you destroy, there are hundreds more that shall take their place".

     Yellow Zelkova 
  • A Father to His Men: Implied as the soldiers under his command seem to share his enthusiasm for victory.
  • Blood Knight: Jumps at the chance to fight the Sonic Team, demanding to face them first.
  • Boisterous Bruiser: He regularly seems jovial in his battles, my friend
  • Card-Carrying Villain: Has stated himself to be evil a few times.
  • Disney Death: After his fight with Knuckles he falls into a volcano. Subverted in that he visibly catches on fire briefly.
  • Dumb Muscle: While undoubtedly the strongest of the 4 commanders (and possibly stronger than Dark Oak), he is as dumb as a slab of pork and just as hammy.
    • It is implied in a flashback that he used to be reasonably intelligent, though it seems to have faded over the years.
  • Faux Affably Evil: Despite his dull wit and moments of being absolutely goofy (Eggman tattoos anyone?), he gets his hands dirty more than any other commander, fighting against Sonic and nearly destroys them multiple times.
  • Front Line General: Not so much as leading his troops into battle as lead only himself into battle.
  • Large Ham: Pick ME! I shall be the representative for this TROPE!
  • Pet the Dog: He is the only one of the 3 remaining commanders (with the possible exception of Dark Oak) to miss his fellow commander Red Pine, claiming he was almost as strong as him (or in the case of the sub, was always careful).
  • The Brute: obviously.
  • Villainous Breakdown: Suffers one as he fails to defeat Knuckles and after he knocks his armor off.

     Red Pine 
  • Continuity Nod: Is constantly referenced to after his death and is shown with the others and Dark Oak in their group picture after their people's history is revealed.
  • Forgotten Fallen Friend: Would be a villainous example if it wasn't subverted. Despite appearing once, he is mentioned in multiple episodes in passing, immediately after his death.
  • [[Redshirt]]: Quite literally.
  • Sacrificial Lamb: Appears for half of one episode and instantly dies, despite being one of the 4 commanders.
  • Small Role, Big Impact: Despite being seen in just one episode, he sets in motion the second half of the Metarex Saga and reveals the existence of the 4 commanders.

     Black Narcissus 
  • Frontline General: Seen leading a campaign on an unnamed world.
  • Manipulative Bastard: Seems to be his hat and prefers to plot and scheme over diplomacy (Pale Bay Leaf) or brute force (Yellow Zelkova).
  • Narcissist: In his name.
  • The Dragon: Shares this with Pale Bay Leaf to some extent, and they are the only commanders of the original 4 remaining when Dark Oak activates forestation.
  • The Smart Guy: Boasts his intelligence and is a natural plotter, manipulating people to do as he wants. Also knows better than to go to battle blind, wanting to gauge Sonic's abilities first before committing forces.
  • Weak, but Skilled: While he is a good plotter and capable of bending people to fall where he needs them to, he is a terrible fighter (losing to Decoe and Bocoe and Bokkun).

     Pale Bay Leaf 
  • Arm Chair Military: Unlike Yellow Zelkova (who constantly brawls with Sonic's forces), Red Pine (who goes down with his ship), and Black Narcissus (who is first seen leading a campaign planet side), Bay Leaf only fights himself at the end of the series (even his ship is seldom seen in battle, as Shadow destroys an entire fleet, but he appears later, indicating he wasn't there).
  • Genre Blind: Doesn't check to see if it was a trick after he thinks he destroyed the Blue Typhoon, gleefully going off to tell Dark Oak the good news.
  • I Lied: Played With. It is unknown if he was going to keep his promise to give the Freedom Fighters a spot in the Metarex hierarchy, but since they failed it is a moot point.
  • Inter-Service Rivalry: Averted. While it looks like he and the other commanders do not do well with each other, as Pale Bay Leaf points out "we're not fighting, just having a difference of opinion".
  • Manipulative Bastard: More of the diplomatic type (as opposed to Black Narcissus' behind the scenes plotting).
  • The Dragon: Shares this with Black Narcissus to some extent, and they are the only commanders of the original 4 remaining when Dark Oak activates forestation.
