Jack The Hedgehog (Sonic Boom)

Jack The Hedgehog is a main character of the fandom series Sonic Boom: Mark's World. He is an anthropomorphic green hedgehog with spiky green hair who is well known as the best friend of Mark The Mongoose. Unlike his Modern counterpart, Jack is known as the "man in charge of everything," is serious on most occasions, and cannot cope with Mark's silliness most of the time. Because of this, the two tend to argue quite a bit, but he still tries to care about him.
