Shadow the Hedgehog is a character in the Sonic the Hedgehog series. He is an anti-hero and the dark rival of Sonic the Hedgehog and first appeared in the Dreamcast game Sonic Adventure 2. He has also appeared in some of the Sonic Archie Comics. Shadow is 3'3" tall, and weighs 77 lbs, exactly like Sonic.
History
All of the details about Shadow's past are extremely clouded. Shadow is the end result of the "Ultimate Life Form" project (called "Project: Shadow"), a secret government genetics project shut down a half century ago whose objective was to reach immortality. He was created by Professor Gerald Robotnik, the grandfather of Doctor Eggman with the help of Black Doom (who had his own shifty motives to have Shadow collect the Chaos Emeralds so he can teleport the Black Comet to Earth and take over Earth) aboard the Space Colony ARK. Shadow seemed to have developed a friendship with the Professor's granddaughter, Maria Robotnik and often looked down to Earth, wondering what the purpose to his life was. When the military attacked ARK to shut down the Ultimate Life Form project, Maria supposedly sacrificed herself in order to let Shadow escape to Earth in a suspended animation capsule. Shadow still mourns over Maria's death. His capsule was captured by the military and stored in the Prison Island for 50 years, until Dr. Eggman attacked the complex looking for "his grandfather's legacy" and freed him. Personality Shadow is a lone wolf and an anti-hero; his motives are unknown and his true alignment (good or evil) is a mystery. He is generally quiet, and a loner - distancing himself from most of the Sonic cast. He is constantly haunted by his memories of his beloved Maria. He is cold, and arrogant. He generally isn't a very pleasant person to be around, but always loyal to his closest allies, unless he sees them as an obstacle. He is fueled by revenge on the humans for the death of Maria, and later his quest to discover the truth of his past.

Abilities
Shadow possesses many of his rival Sonic's abilities, namely the same blistering speed and agility.Shadow's trademark move is Chaos Control. Using the power of a single Chaos Emerald, he can warp time and space. In Shadow the Hedgehog, when he becomes Hero Shadow, he uses Chaos Control to fly through part of the level; doing damage to enemies he passes. The Chaos Control is usually used to freeze time or to teleport (or possibly both if those viewing someone move from somewhere to somewhere else in 'no time', then it would look like they warped). He is only seen freezing time in Sonic Adventure 2 in 2 player mode, but in Sonic Heroes the time freeze is an effect of Team Dark's "Team Blast" special move, "Chaos Inferno". He uses the Chaos Control ability four times in Sonic Adventure 2: once to escape from Sonic using the green emerald, once to rescue Rouge from the military base before it blows up, and once during the final duel against Sonic. He uses it one last time to send away the defeated Finalhazard, although this results in his apparent death. Shadow, like Sonic, can use the light dash. Sonic can also use Chaos Control, even with a fake emerald, though he only realizes this later. Shadow used Chaos Control at the end of his own game using all seven Chaos Emeralds. Shadow also has a chaos move called Chaos Spear, a move that lets Shadow send a bolt of yellow energy at his enemies, and is similar to Sonic's Sonic Wind (although in Shadow the Hedgehog, he could only use Chaos Spear while in Super form). In Shadow the Hedgehog, Shadow can use one of two Chaos-based moves, depending on what actions the player takes. Attacking Black Arms aliens (or other dark based characters), healing G.U.N. troops (or other hero based characters) and clearing away environmental debris will fill Shadow's Hero Gauge, enabling him to become to use Chaos Control, which (in this game) lets him fly at blistering speeds through a portion of the level while doing a fraction of damage to enemies he passes and/or slow down time during a boss fight. Attacking G.U.N. soldiers(or other hero based characters), healing aliens (or other dark based characters), and destroying regular parts of the environment (i.e. trees, rocks) will fill up Shadow's Dark Gauge, allows him to use a new power called "Chaos Blast," a red wave of energy that destroys almost everything in its path at close range, 20 meters to be exact. Both Chaos Control and Chaos Blast allow Shadow to also gain temporary invincibility and unlimited ammunition. He and Sonic have been observed using their chaos powers while Super Sonic and Super Shadow. Shadow shares every ability that Sonic has, meaning that they are truly rivals. Sonic can also perform the powerful Chaos abilities Shadow uses, like in Sonic Adventure 2 during their final duel, Sonic uses very similar chaos moves that are only different from Shadow's in name and appearance. Sonic, however, seems to prefer relying on his speed and other natural abilities to get the job done. Sonic has never been seen using the Chaos Blast move, but this is most likely because Sonic has never done enough evil at one time to allow this. Sonic does, however know about Chaos Blast, he even tells Shadow at the beginning of "Shadow the Hedgehog" how to get it, and what it does, before Shadow even uses it for the first time. It is also unknown if Shadow is capable of the "Dark" Super form used by Sonic in Sonic X. Another difference is that, while Shadow is willing to use guns, Sonic has said towards the beginning of "Shadow the Hedgehog" that he "wouldn't be caught dead using those things".
