Name: Sonic the Hedgehog.
Powers/Abilities: Super speed, super strength, and enhanced stamina.
Backstory: Sonic the Hedgehog is an independent hero and freedom fighter. He is native to an alternate dimension where the original Sonic the Hedgehog doesn’t exist. In that alternate reality, this Sonic adopted the same name purely due to coincidence, being named Sonic the hedgehog because he was a hedgehog who could run at supersonic speeds. Sonic had spent his life going on his own adventures with a wide cast of allies and enemies of his own.
One day, he got into a massive battle with his currently undisclosed arch nemesis. In that battle, Sonic needed to break his speed limit in order to defeat this villain. In doing this, his own speed merged with the reality-altering powers of his enemy, transporting him to another world.
In this new dimension, he has been met with ridicule by the locals for calling himself Sonic the hedgehog. At this point, he isn’t yet aware that he is in another universe, believing that he was transported to another part of the galaxy in his own world.
Along with having a different appearance, he has an almost opposite personality to his counterpart. This Sonic is very quiet, polite, respectful, as well as holding himself to many responsibilities. He never taunts or belittles anyone he fights, doing his best to pragmatically finish any battle he’s in as soon as he can.
This alternate Sonic also hates Chili Dogs, believing them to be a fatty and unhealthy food that nobody should ever eat.
