Arendelle Legend Trilogy 

Shadow the Hedgehog

 

Shadow the Hedgehog is an anthropomorphic black hedgehog/Black Arm hybrid and the arch-rival of Sonic the Hedgehog. 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 granddaughter Maria Robotnik, but he was captured and put into stasis by the military when he was deemed a threat to humanity.

Fifty years later, Shadow 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 to help save it from Gerald's doomsday plans. 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 GUN.

Shadow is 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 use Chaos Control with a Chaos Emerald. While preferring to work alone, he will help Sonic and friends when necessary. He'a an expert at guns as well, although he can be a bit gun shy, which seldomly happens.

After he had been around to fight for G.U.N. and came to be around Sonic and his friends more often than not, he decided to go with them to Arendelle. This was a great opportunity to see what Sonic's life was like before he had come to the other world. After the earthquake occured, he thought that Mephiles was around. So he left with Amy, Blaze, Sonic, and Knuckles. Then, as soon as he came into Rootcore, which was the sorceress Udonna's home, he started to feel the power of lightning and thunder within him. This then caused him to become the Yellow Mystic Ranger. However, before he had that power, he had his doubts about believing in magic.

After once he had finished defeating an entire wave of Hideacks and Black Arms, he then found out that Mephiles had been reborn from the dead for the thrid time. He defeated him as the Yellow Mystic Ranger. Then he went back to Arendelle and ultimately defeated Black Doom again for good. Then he left with the others to save Arendelle for good. However, he had ended up in a little bit of a jam until Sonic had come back. Then they returned and he lived in Arendelle as an agent of Elsa's international security organization I.C.E. as well as G.U.N.
