Tails is basically the Tails from Sonic, but from an alternate universe where Zombies attacked. He was bitten by a Zombie, but managed to resist, making him good, but immortal. His friends were eaten, so he managed to get here using his spaceship. It was a sad past for him. He is very kind, and because of his Immortality, he doesn't fight often unless he wanted to, even if someone stabbed him, he gets hurt, but not do anything about it. He can feel pain, and sometimes willingly to harm himself.
