    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.

  • The Ace: He's a professional guardian. Its the reason why he dedicated his life to protect the Master Emerald.
  • 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.
  • Battle Couple: With Rouge.
  • Badass: One of the biggest examples of the show.
  • Beware the Nice Ones: He's one of the most down to earth and humble characters on the show, but NEVER hurt innocents in front of him, steal the Master Emerald or make him angry. He's doesn't really take kindly to people mistaking him as Sonic either.
  • Berserk Button: Do NOT mistake him as Sonic. See more on Beware the Nice Ones on the top.
  • 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".
  • Boisterous Bruiser: He's quite a fun guy when in the right mood.
  • Butt Monkey: In season 3, he gets more prone to slapstick, and often becomes 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: Earlier in season 1, Knuckles was annoyed of Sonic being so reckless that he actually sent everyone to earth in a failed attempt to defeat Eggman, because now they were comming to a whole new planet they don't even know, and Knuckles doesn't know if the Master Emerald will be stolen. Because of this, Knuckles did not trust Sonic and refused to consider him a friend. In the middle of the season anyhow, Knuckles is slowly starting to accept being Sonic's friend, and though he still confronts Sonic when he acts before he thinks, Knuckles develops a geniune friendship with him in season 2 onwards.
  • The Cassandra: Knuckles seems to have to deal with being this in most episodes.
  • Chronic Hero Syndrome: The reason why he always forgives Dr. Eggman. Knuckles's moral code is to give everyone a second chance at any time, even if it's Eggman who tricked him once too many times.
  • Deadpan Snarker: Despite how he's a very serious individual, he does have a witty sense of humor. Especially when the episodes show off his Only Sane Man traits.
  • The Comically Serious
  • Commander Contrarian: Though he means well.
  • Cute Little Fangs: He has a whole set of them when he's mad or excited.
  • Determinator: He's determined to protect the Master Emerald as long as he lives. He's also extremly persistant when fighting his opponoments, getting up no matter how much pain he takes.
  • Depending on the Writer: Knuckles is portrayed as a one of the more serious characters in most episodes, while others make him look comedic.
  • Dreadlock Rasta: This adaption gives him dreads along with his quills.
  • Defeat Means Respect: He respected Emerl with a handshake and complemented him after being defeated by him.
  • Dude, Where's My Respect?: He almost never gets any respect. He's guarding the Master Emerald for everyone's sake, yet all people do is mock him or count him out of the group, and never thank him for being generous. This goes even to the point where he saves Rouge, and all she does is tell him to let go of her, even though she complained like a hypocrite when he didn't thank her. Knuckles was on to help Cosmo, yet she only thanks Sonic and Tails.
  • 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 Nice: Despite being one of the good guys, he has a very short temper and is prone to punching someone anytime they insult him or make a sarcastic remark. Other than that, he can be friendly when he's in a good mood.
  • 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.
  • 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.
  • Heroes 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.
  • Hair-Trigger Temper: Even the slightest abrasive comment will trigger a flurry of his punches.
  • 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.
  • 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. He kept getting up while fighting against Yellow Zelkova in episode 72, no matter how much he had to suffer.
  • 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.
  • The So-Called Coward: In episode 45, he was being mocked and called a coward for not wanting to enter the tournament. [[Irony As it turns out, he was way braver than all of them]].
  • 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.
  • 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. While she means well, she can be a bit of a handle and often glomps Sonic. In battle, she uses her trust Piko Piko Hammer. Turns deadly with her Hair-Trigger Temper.

    Cream the Rabbit & Cheese 
Voiced by: Sayaka Aoki (Cream, JP), Ryo Hirohashi (Cheese, JP), Rebecca Honig (Both, EN)

A six-year old rabbit, Cream is the Tagalong Kid of the protagonists. She is very sweet and good-natured, though she misses her mother Vanilla. Cream is accompanied by Cheese, a loyal Chao who usually mirrors her feelings.

    Rouge the Bat 
Voiced by: Rumi Ochiai (JP), Caren Manuel (EN)

A jewel thief bat who begins neutrally aligned but ends up as a government agent working for the President of the United States. She forms a friendship with her partner Topaz, and has a complicated relationship with Knuckles.

  • Anti-Hero: She only does heroic work for money or emeralds in return.
  • Battle Couple: With Knuckles.
  • Belligerent Sexual Tension: The two are rivals like in the games. However, their love interest in each other is more emphasized as the two have a few romantic conversations with each other which hinted their love in a few episodes.
  • Boobs of Steel: Has the largest breasts out of the Sonic girls due to her age and image. She literally kicks people asses with kickboxing, making her one of the stronger female characters.
  • Classy Cat-Burglar: She is a renowned jewel thief.
  • Combat Stilettos: Equipped with metal soles.
  • Cowboy Cop
  • Cute Little Fangs: You don't see them that often, but they're there.

  • Deadpan Snarker: She never holds back her sass, that's for sure.
  • Femme Fatale: Her voluptuous and daring attitude turns any man's head.
  • Flight: Being a bat, Rouge is able to fly and glide.
  • Greed: She loves gems and wishes that all the world's gems were hers.
  • Guile Heroine
  • Humanoid Female Animal: Aside from her ears, wings, and tail, she has the most human-like body proportions in the series.
  • Impossibly-Low Neckline: Might be justified by the fact a high neckline would be inconvenient for winged characters.
  • Jerk with a Heart of Gold: She may be selfish and greedy at times, but she cares about Topaz and the others.
  • Kick Chick: She uses attacks with kicks rather than punching.
  • Light Feminine and Dark Feminine: The Dark Feminine to Amy's Light Feminine.
  • Lack of Empathy: Towards some people, though not everyone.
  • Loveable Rogue: She's a government agent, but she's still a thief, too. Better yet, the title works even if you misspell it!
  • Male Gaze: She tends to pose in... odd ways in the series.
  • Ms. Fanservice: It should be noted she's worn the most outfits out of any of the cast.
  • Ms. Vice Girl: She can be heroic, but is always after jewels.
  • Pint-Sized Powerhouse
  • Sexophone: Her appearances are almost always accompanied by this.
  • The Tease: She sarcastically flirts with Knuckles.
  • Tsundere: One moment she's teasing, insulting and beating up Knuckles and the other she starts flirting with him and making her interest on him clear.
  • The Vamp: She doesn't suck blood, but everything else about her is batty.
  • Vitriolic Best Buds: With Topaz. Though at first the regimental Topaz disapproves of the scheming Rouge (who keeps calling her an old lady), the two become friends fast.
  • Weaksauce Weakness: She can't handle loud, high-pitched noises due to her sensitive bat ears.
  • Well, Excuse Me, Princess!: In episode 52, Rogue starts criticizing Knuckles' tough guy attitude and demands him to treat her better, to Knuckles' great dismay.
  • White Hair, Black Heart: She's not evil (not always anyway), but she's selfish and manipulative enough to qualify.
  • Wouldn't Hurt a Child: She kisses Tails to embarrass him into losing his battle with her instead of fighting him.

Voiced by: Ken Yamaguchi (Decoe, JP), Bin Shimada (Bocoe, JP), Andrew Rannells (Decoe, EN), Darren Dunstan (Bocoe, EN)

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

  • 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.
  • Badass: He actually defeated Super Sonic, and came close to beating Shadow.
  • 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
  • Darth Vader Clone: Fits this in every way. Dark and Troubled Past, Badass Cape, Cool Helmet, Noble Demon, We Can Rule Toghetter etc. Plus, his desire to destroy planets, and formerly being a hero, to doing a Heel-Face Turn after in the very end,
  • Drunk with Power
  • End of the World as We Know It: He removes planet eggs, allowing the planets to wither and die.
  • Even Evil Has Loved Ones
  • Knight of Cerebus: The show gets A LOT 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".
  • Knight of Cerebus: Shared with and possibly excelled over Dark Oak. Compared to the rest of his subordinates, Pale Bay Leaf is seriously played and completely ruthless and at times darkly sadistic, particularly in his treatment of Molly's army.
  • 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.
