Sonic rivals Shaodw2

Shadow the Hedgehog is a fictional character from the Sonic the Hedgehog series. He is an anthropomorphic black and red hedgehog or Black Arm hybrid and the arch-rival of Sonic the Hedgehog and possesses skills and abilities which rival him. Shadow was created as the "Ultimate Life Form" by Gerald Robotnik, using the DNA of Black Doom, and is the final result of Project Shadow. His purpose was to provide ways of developing cures for deadly illnesses that had no cures, namely for Gerald's 12-year old granddaughter, Dr. Eggman and Eggman Nega's 12-year old cousin, Maria Robotnik, but he was captured and put into stasis by the military when he was deemed a threat to humanity.

He was released by Dr. Eggman to help him conquer the world. Initially, Shadow sought to destroy Earth to avenge Maria, who had been killed by the military, but was persuaded by Amy Rose to help save it from Gerald's doomsday device. In the process, Shadow lost his memories and he sought to uncover his past, which brought him into contact with the Black Arms. Ultimately, Shadow thwarted Black Doom and saved the world. From there, Shadow continued his mission to protect humanity by becoming a special agent of G.U.N. units.

Shadow is dark, smug, arrogant, sharp-witted, always on edge and has a strong sense of purpose, willing to accomplish his goals by any means necessary. Essentially a dark version of Sonic, Shadow can match him in both speed and skill, and possesses the ability to to warp time and space by using Chaos Control with a Chaos Emerald. While preferring to work alone, he will help Sonic and friends when necessary.

According to an official poll, Shadow is the second most popular character in the series, behind only Sonic himself.

Shadow also appears in James Cameron's Sonic Cinematic Universe, played by Ben Affleck through voice and motion capture. His role in the franchise is the same as in his current video game appearances, on which he is an officer and agent-later-commander of G.U.N. (Guardian Units of Nations) and a rival-turned-ally to Sonic. His origin story (revealed in Shadow and Rouge) is the same as in Sonic Adventure 2 and the 2005 video game.

He appears as one of the Playable DLC Guests for Tekken 7, with Kirk Thornton voicing him again (similar to his fellow Sonic the Hedgehog Multiverse Guests such as Sally and Blaze, all of his dialogues would be spoken in English, even though Blaze, Sally and Shadow came from different places).

Similarly, he would be a playable Guest for the sequel to PlayStation All-Stars Battle Royale in place of Sonic, much like how Akuma is playable in Tekken 7.
