Sonic The Hedgehog

Age: 16 Species: Hedgehog Special ability: Super speed

First appearance: Sonic The Hedgehog, 1991

The one and only Blue Blur! Sonic's design was "a mix of Mickey Mouse and Felix the Cat." But it yielded something way cooler and now we have a spiky blue speed demon with a heart of gold and an attitude. Sonic's got a bit of a short temper, but there's no better hero. He fights any adversary (usually Robotnik) to save those in danger. He leads the Knothole Freedom Fighters.

Super Sonic

First appearance: Sonic The Hedgehog 2, 1992

When Sonic grabs all 7 Chaos Emeralds and at least 50 rings, he transforms into Super Sonic. Gold in color and reaching speed fast enough to not even touch the ground, Super Sonic is invincible. In Sonic Adventure, when he reaches max speed, he turns into a bolt of lightning with a super powerful attack.

Hyper Sonic

First appearance: Sonic and Knuckles (locked-on to Sonic 3), 1994

Sonic must attain all 7 Chaos Emeralds along with all 7 Super Emeralds. Then he can become Hyper Sonic, an even stronger version of Super Sonic. Hyper Sonic flashes the different colors of the Emeralds. He moves so fast there is a trail of multiple images behind him. His special attack causes a flash of light that destroys all nearby enemies.

Miles "Tails" Prower

Age: 10 Species: Fox Special ability: Can fly and attack with his two tails

First appearance: Sonic The Hedgehog 2, 1992

Tails is Sonic's best buddy. He looks up to Sonic as a hero and a brother, and aspires to be like him. Tails was born with two tails, and he twirls them like helicopter blades to take off. When running fast, he uses his tails to propel him over the ground. He is an excellent pilot and very smart for his age.

Super Tails

First appearance: Sonic and Knuckles (locked-on to Sonic 3), 1994

Tails has to collect all 7 Chaos Emeralds and all 7 Super Emeralds to become Super Tails. He glows a bright orange and is faster and invincible. He has a squadron of birds at his aid that seek out and destroy enemies.

Knuckles The Echidna

Age: 16 Species: Echidna(spiny anteater) Special ability: Gliding, using his knuckles

First appearance: Sonic The Hedgehog 3, 1994

Knuckles is one hot-headed echidna, or so they say. He's quick to assume the worst, but seems to be the most serious about his work. He was born on the Floating Island, and is the guardian of the Master Emerald. For a long time, Knuckles thought he was the last of his kind, until (in the comic) he found the hidden city of Echindaopolis with Juli-su. He also met his father, whom he thought was dead, and found that a whole Brotherhood was helping him to be guardian.  He has recently undergone some very wierd changes after the Floating Island was once again transported to another zone.  He now glows green and wields the power of the Chaos Emeralds.

Super Knuckles

First appearance: Sonic and Knuckles (locked-on to Sonic 3), 1994

To become Super Knuckles, Knuckles only needs to do the same as Sonic and collect all 7 Chaos Emeralds. He glows pink, is invincible and moves quickly.

Hyper Knuckles

First appearance: Sonic and Knuckles (locked-on to Sonic 3), 1994

Knuckles has to attain the 7 Super Emeralds to add to the 7 Chaos Emeralds. Then he can become Hyper Knuckles. Hyper Knuckles glows pink, and runs fast enough to make multiple images. His special attack is slamming into walls hard enough to shake the ground and kill all nearby enemies.

Amy Rose

Age: 12(?) Species: Hedgehog Special ability: Wields Piko-piko hammer

First appearance: Sonic The Hedgehog CD, 1993

Amy Rose is a little pink hedgehog with a huge crush on Sonic. In Sonic CD, she went as Princess Sally in America, but the rename was taken away in Sonic R. Sonic had to save her from Mecha Sonic when they first met, but he tries to save himself from her in Sonic Adventure. Her first appearance in the comic was the landmark issue #25, Sonic CD adaptation, where she was kidnapped. Later she came back and stayed on as a regular. She wants nothing more than to be a full-fledged Freedom Fighter.

Big The Cat

Age: ? Species: Cat Special ability: Strength, fishing

First appearance: Sonic Adventure, 1999

Big is one dopey, easy going feline (what a disgrace to us cats!) His adventure began when his best friend, Froggy, became possessed by Chaos' tail, swallowed a Chaos Emerald, and ran away. He followed him everywhere, fishing for him and losing him again and again. He met several strange characters along the way, like Sonic and Tails. Finally, with Sonic's help, he got Froggy and they went home happy. In the comic adaptation, Big lives in the Mysterious Cat Country where Chaos is said to have been trapped.

E-102 'gamma'

Age: ? Species: Roboticized bird Special ability: Homing laser

First appearance: Sonic Adventure, 1999

Gamma is the second of Robotnik's E-100 series (guess 'Buttnik can't count, cause wouldn't 101 be the second…?). Its mission at first is to do as Robotnik tells it. But after meeting Amy and her bird friend, Gamma realizes who the real enemy is. It sets out to save the other E-100 'bots, and finally saves itself as well. It flies away as a pink bird, reunited with its family. (Personally I'm confused. As a 'bot it had a male voice, then it's a pink girly bird. Hm…)

Dr. Ivo Robotnik

Age:? Species: Overlander (4-fingered human) Special ability: Evil genius

First appearance: Sonic The Hedgehog, 1991

Never have I seen a bad guy with so many different forms. First his video game form, looking like a ball with arms and legs, then the ABC cartoon and comic form, then the syndicated show form where he looked like he had a sausage for a nose, and finally Sonic Adventure, looking like an update of the original. Anyway, born Julian Kintobor of the House of Ivo, Robotnik has always been Sonic's worst enemy, capturing helpless animals and turning them into machines. In the comic and (good) show, he tricked King Maxamillian Acorn into trusting him as Warlord. Then he threw the king in another dimension and took over, re-christening the city of Mobotropolis into Robotropolis. It took about ten years of fighting before he was killed by the Freedom Fighters: by Sonic and Sally in the ABC show, and by his nephew Snively and the Ultimate Annihilator in the comic. The comic adaptation of Sonic Adventure uses Robo-Robotnik, one of his other-dimensional selves, having downloaded his memory into a robotic body like the one we know now.

Tikal

Age: 16(?) Species: Echidna First appearance: Sonic Adventure, 1999

Tikal was the princess of a village of Echidnas long ago. She met Chaos and befriended him and the Chao. Her father didn't believe in peace as she did, and had his men attack the Chao to obtain the Master Emerald and Chaos Emeralds. When Chaos countered and nearly destroyed the world, she locked him in the Master Emerald, along with herself.

Chaos

Age: ? Species: Living water monster Special ability: Grows stronger with addition of Chaos Emeralds First appearance: Sonic Adventure, 1999

Once the benevolent protector of Chao, Chaos grew furious when the Echidnas tried to take the Master Emerald and attacked the Chao. He was locked in the Emerald by and with Tikal. Years later, he was released by Robotnik to reign terror on Station Square. He reached his sixth level before being defeated by Sonic. After that he was so filled with anger and hatred he found the last Emerald himself and flooded Station Square. When Robotnik tried to stop him, he destroyed the Egg Carrier 2. He was defeated by Super Sonic, and his anger was neutralized. He then went to a peaceful place with Tikal.

Espio The Chameleon

Age: 16(?) Species: Chameleon Special ability: Sticking to surfaces, camouflage

First appearance: Knuckles' Chaotix, 1995

Espio is cool and kind of mysterious. He first met Knuckles after being saved from the Combi-Catcher in the game, and before the whole mess started in the comic adaptation. He has a hot temper and an intense drive in everything he does. He seems a little quiet and introverted at first, but he's a very good friend. He's also quick and cunning and values freedom above all else. (Sigh…)

Mighty The Armadillo

Age: 16(?) Species: Armadillo Special ability: Amazing strength

First appearance: Sonic Arcade, 1993

Mighty is aptly named. He's strong, smart, and confident, and can't stand weakness in anything. His heroism complements his determination and strength. In Knuckles Chaotix, he is Knuckles' good friend. Sonic Arcade puts him alongside Sonic and Ray The Squirrel. The comic book has him meeting the Chaotix along with Heavy and Bomb inside a mountain. It also says he met Sonic and Ray years ago in one of Robotnik's prisons. No matter how you look at him, Mighty is an exceptional part of the Chaotix.

Vector The Crocodile

Age: 16(?) Species: Crocodile Special ability: Smooth moves, vector jumps

First appearance: Knuckles' Chaotix, 1995

Vector is a hip croc with an attitude and a short fuse. Not as cool as he seems to think, Vector has been known to goof up on more than one occasion. Still, he manages to keep his cool in a tough situation and slip around danger. He loves to run, dance, eat, and hang with his friends. The comic stars him as one of Knuckles' first friends of the Chaotix, troublesome as he may be.

Charmy Bee

Age: 16 Species: Bee Special ability: Flight

First appearance: Knuckles' Chaotix, 1995

Very sophisticated for his age, Charmy always handles trouble with a charming manner. He can buzz along the ground at high speed or zip through the air. In both versions of the story, Charmy meets Knuckles while looking for new flowers on the Island. What he found instead was a ton of trouble. When not in flight mode, he changes form to be not too much smaller than his comrades. He is in fact prince of the hive he ran from. He finally returned home to bury his friend Mello. There he decided to take his rightful place and leave the team behind.

Heavy and Bomb

Ages: ? Species: Robots Special ability: Bomb- survive explosion, Heavy- resistant exterior First appearance: Knuckles' Chaotix, 1995

These two are renegade robots that once served Robotnik. They offered their services to the Chaotix and proved to be useful. Later they tried to live a peaceful life, but were unsuccessful. So they enlisted in Geoffrey St. John's team of Special Forces for the king.

Ray The Squirrel

Age: ? Species: Squirrel Special ability: ?

First appearance: Sonic Arcade, 1993

Ray is a very kind and shy little guy. He usually stutters when he talks, but that makes him no less a fighter. In the comic, he had been trapped in another zone for almost 10 years, stuck holding on to an Emerald shard. Time had barely passed for him. Now free, he enjoys his time with his good friend, Mighty.

Nack The Weasel

Age: ? Species: Weasel Special ability: ?

First appearance: Sonic Triple Trouble, 1994

Nack is one of the most notorious bounty hunters on Mobius. He works for whoever hires him. It was he who went after the Emeralds for Robotnik. Later he was hired again to capture and deliver Sonic for Roboticization. He had to fly (or rather, get thrown) and missed out on his payment there. Afterwards he was Sonic's only means of clearing his name. Finally he was placed in the Devil's Gulag, only to escape and become one of Snively's henchmen.

Shadow the Hedgehog

Age: ?, immortal Species: Hedgehog Special ability: Chaos Control

First appearance: Sonic Adventure 2, 2001

Shadow's past is a bit of a mystery to everyone, including Shadow. He thought himself to be the ultimate lifeform created by Prof. Gerald Robotnik (Kintobor), but it turned out he had been lied to. He was indeed created by Gerald, and was immortal, but aside from having Chaos Control, he was otherwise a normal hedgehog. Shadow harbored memories of a young crippled girl named Maria, Gerald's granddaughter, who was his best friend. Her dying wish before Shadow was shipped to Mobius from the space colony, ARK, was that he make it so the people on the planet could be happy. His memories got mixed up with Geralds programming for revenge on the humans, but he eventually got things right. He helped Sonic save the world.

Super Shadow

First appearance: Sonic Adventure 2, 2001

Shadow used the power of the Chaos Emeralds along with Sonic to become Super Shadow. Together they defeated the Biolizard/Finalhazard, and used Chaos Control to teleport the plummeting ARK back into orbit. He then fell into the atmosphere himself, dying perhaps by choice, perhaps because he couldn't control his super form as well as Sonic.

Rouge the Bat

Age: ? Species: Bat Special Ability: Natural radar for gems, gliding, climbing

Rouge is a smart, sexy treasure hunter who knows how to get what she wants. She'll do anything for some jewels, including spying for whoever hires her. She was hired by the President of Station Square to retrieve the stolen chaos emerald from Shadow, as well as do some research on Robotnik. She found out more about Project: Shadow than she bargained for. She also found herself interested in a fellow treasure hunter that we all know (who, BTW is taken by Juli-su!!)

Maria Robotnik/ Kintobor

Age: ? Species: Overlander

First Appearance: Sonic Adventure 2, 2001

Maria is the granddaughter of Gerald, and cousin to Ivo Robotnik. She exists in the memories of Shadow. She was killed in the assault on the ARK. Maria's last wish was that Shadow give the people of Mobius a chance to be happy.

Professor Gerald Robotnik/ Kintobor

Age: ? Species: Overlander Special ability: Genius

First Appearance: Sonic Adventure 2, 2001

Gerald was known as the greatest scientist of his time. However, while working on Project: Shadow, the prototype of ultimate life, the space colony he was on, ARK, was attacked by the military. They wanted the prototype for themselves. Once they found how dangerous the prototype was, they ordered it sealed and Gerald was to be executed. Before he was killed, he programmed Shadow the Hedgehog to exact revenge on the people of the planet, and set up the Eclipse Cannon to be the force to do it.
