Backstory:
Grew up on Mars and lived pretty peacefully. Loved to tinker on bikes and other mechanics.
When the Plutarkians (a kind of fish-looking alien, they are very rude and nasty) attacked their planet for their resources, Hunter joined the Freedom Fighters alongside other Martian Mice to fight the Plutarkians. He was captured and imprisoned where Dr. Carbunkle performed nasty experiments on the captives (Replacement of limbs, cloning, nasty shit etc).

Hunter’s DNA was mixed with feline DNA, in hope to create some sort of super hybrid. The process was cut off as the captured mice were freed, however, Hunter still got affected. His buck teeth fell out, and his gums were replaced with feline teeth. His eyes changed color from red to yellow. His light grey fur starting to get striped markings that appear more and more the older he gets. He also got claws on hands and feet, and a fluffier tail. His reflexes, agility and movement also got heightened.

Because of his mixed DNA, fitting in among the other mice got difficult. After a while it became too much and he decided it was best to leave. He tried a number of other planets and galaxies, but ended up on Earth in the end. In the start of his life on earth, he travelled around and explore. He finally settled down in a strange down called Knifes Edge, where he could sorta actually fit in without having to hide, considering all the other weird shit that already lived in the town.
