Chaos

Chaos (Kaosu) is a video game character and the main antagonist in the video game Sonic Adventure for the Sega Dreamcast. Chaos is the first main antagonist of a Sonic game that is not Doctor Eggman. This eventually became common in the 3D games, with Eggman's role as the main villain being replaced by other villains (though often Eggman still makes an appearance). Chaos is an immortal, ageless god-like creature (referred to as the "God of Destruction" by Eggman) that seems composed almost entirely of water (save for his brain, green glowing eyes, and, in some later forms, bones) but is also said to be concentrated Chaos Emerald energy (in Sonic X, Doctor Eggman implies that it is composed of "Chaos energy in a liquid state"), however it has been revealed that Chaos is a Chao that came into contact with the Chaos Emeralds.[1] It was trapped inside the Master Emerald for thousands of years before being released by Dr. Eggman in a bid to conquer the world. It was also the original guardian of the Chaos Emeralds, Chao, and the Master Emerald. In Sonic Adventure it absorbed the negative energy of the Chaos Emeralds to attain its final and strongest form.

E-123 Omega

E-123 Omega (Omega), or, technically, E-123 O, is a fictional robot from the Sonic the Hedgehog video game universe, first appearing as a fully playable character in the multiplatform game Sonic Heroes, which was first released in Japan on December 30th, 2003. His character designer is either Yuji Uekawa or Takashi Iizuka. He bears a strong resemblance to another character in the series, E-102 Gamma, who is part of the same robotics production line. In the games, he was created by Doctor Eggman, and is out to destroy him due to lack of respect and want for revenge. Omega is 150 cm tall (4' 11") and weighs 1,230.512 kg (2712.77 lbs).[1] He has the capital Omega symbol (O) painted on his shoulders, in contrast to all the other E-100s, which had the lowercase Greek letter (?), possibly representing that he is the most powerful of Eggman's E-Series (though the Original set of E-100s from Sonic Adventure had various Greek Sybols). Though they may have used the capital letter because it's far more noticeable and well known than the lowercase.

Silver the Hedgehog

Silver the Hedgehog (Shiruba za Hejjihoggu) is a video game character in the Sonic the Hedgehog video game series. He made his debut for the series in the 2006 Sonic the Hedgehog game. He currently appears in four games and is scheduled to be playable in a fifth.

Blaze the Cat

Blaze the Cat (Bureizu za Kyatto) is a fictional character in the Sonic the Hedgehog series, created by Sonic Team and owned by Sega. She made her debut in the Nintendo DS video game, Sonic Rush. Blaze is a lavender, female anthropomorphic cat with yellow eyes.

Due to heavily conflicting information, she either hails from future or another dimension. But also because Eggman Nega, a descendant of Dr. Eggman, comes from the same dimension as her and comes from the future, shown in "Sonic Rivals", Blaze could just come from the future which counts as a different dimension. She is a princess and the defender of the Sol Emeralds, a role similar to that held by Knuckles. Blaze is sometimes referred to as a Queen; She is referred to as "Queen Blaze the Cat" on the official Sega of America Sonic mini site, Sonic Central, as well as the next Sonic the Hedgehog game website. However, in Japanese, her title is ?? kojo,[1] which translates as "imperial princess," suggesting that the references to "Queen" are simply mistranslations.

Cream the Rabbit

Cream the Rabbit ( Kurimu za Rabitto) is a video game character in the Sonic the Hedgehog series of video games. She first debuted in Sonic Advance 2 for the Game Boy Advance on December 19, 2002.

Cream is a young, cream-colored, female, anthropomorphic rabbit who can fly by flapping her ears. She is six years old, 70 cm (2' 3"), and weighs 12 kg (26.4 lbs).[1] Cream is the daughter of Vanilla the Rabbit, and is rarely seen without her lifelong companion, Cheese (Chizu), whom she uses as a method of attack. Their names are references to "cream cheese". She and Charmy Bee are the youngest characters in the Sonic the Hedgehog series, both being six years old.

Metal Sonic

Metal Sonic (Metaru Sonikku) is the fictional "robotic counterpart" and a rival of video game character Sonic the Hedgehog. Being a robot, Metal Sonic has no gender; however, Metal Sonic is referred to as being male, since he is a robot based on a male character, as well as having seemingly masculine programming. According to official polls, Metal Sonic is the most popular villain in the series, and the second most wanted character for future appearances, beaten only by Shadow the Hedgehog, and requested in one part of the poll coming ninth in the top ten of which character people would want to have their own game. His appearances since the 16-bit games have mostly been reserved for big events, such as Sonic Heroes, where he is the main villain, or as a playable character with little or no part in the games' stories.
