Shadow the Hedgehog

"I am the ultimate life form, Shadow the Hedgehog. I will crush anyone who stands in my way!"

- Shadow the Hedgehog 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 warp time and space by using Chaos Control with a Chaos Emerald. While preferring to work alone, he will still help Sonic and friends when necessary.

According to an official poll, Shadow is the second most popular character in the entire series, as a whole thus far behind only Sonic himself.

Iago PUC's ideas

 * 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.
 * Shadow appears as one of the protagonists in Justice League: Rings of the Force, voiced by Christopher Daniel Barnes.
 * Shadow appears in Sonic Mania: The Animated Series, voiced by Adam Baldwin.
 * Shadow appears as a supporting character in Sonic and the Tomb Raider, voiced by Adam Baldwin.
 * Shadow appears in the Disney+ animated crossover miniseries Marvel's All-Star Multiverse, voiced by Adam Baldwin. Along with being a top agent and member of G.U.N., this version of the character is partnered and romantically related to a Mobian tigress named Maria. He first appears in the Free Adventures short episode "Shadow Drift", on which Shadow is assigned to stop a illegal street racing competition in Tokyo, Japan. Appearing in the main episodes, Shadow makes a silent appearance in "The Sky's the Limit", on which he and his fellow G.U.N. soldiers watch Princess Athena's public presentation of the Skycruiser Commandos. Shadow makes his official appearance in "Ultimates", where he and Maria are assigned by the G.U.N. Commander and S.H.I.E.L.D. Director Nick Fury to organize and lead a task force team to hunt down and apprehend the Power Broker (revealed in the end as Taneleer Tivan the Collector), and stop the assassins and bounty hunters hired by the crime-lord against the head members of Babylon-6.
 * Shadow also appears in Comic Con Incorporated as one of the managers in the titular fictional hotel. He works as the night shift security guard.
 * Shadow appears in Sonic Presents... Chao in Space: Behind the Scenes, a comic book tie-in/prequel to Sonic Presents... Chao in Space. Serving as a member of Sonic's filming crew for the titular fictional movie, he and Blaze the Cat were the screenwritters. He is also the one who suggests the core concept of the Galactic Chao Alliance (which he describes as a Chao-owned variant of G.U.N. forces) and the Dark Emerald Empire (which he describes as a family-friendly amalgam of the Eggman Empire and the "dark and gritty" Black Arms) in the movie. Later, during the movie's premiere release night, Shadow is shown in the Red Carpet wearing a militaristic tuxedo with a G.U.N. medal of honor in it.

Video games

 * Shadow is also a DLC playable character in Injustice 2.

Video Games
He appears as one of the Playable DLC Guests for Tekken 7, with Kirk Thornton voicing him once 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 across the Sonic series as a whole itself).

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