Muttski (SatAM)

Muttski is the pet dog of Sonic the Hedgehog in the Sonic the Hedgehog TV series. Along with Uncle Chuck, Muttski was roboticized prior to Sonic joining the Freedom Fighters.

History
Muttski was roboticized sometime in the past, but his original animal form can be seen on a photograph that Sonic shows Tails. While roboticized, Muttski possesses razor sharp teeth which he uses to bite enemies. He is also able to shoot small objects from his mouth at great speed, which he also uses as a weapon.

While Sonic was on a mission to Robotropolis with Tails, Tails spotted Muttski outside one of Doctor Robotnik's factories. He claimed that Muttski looked very "mean", which Sonic insisted was merely a product of the roboticization. Convinced that Muttski wouldn't hurt Sonic, since Sonic was Muttski's best friend, Sonic called to the dog. However, Muttski was under Robotnik's control and immediately attacked Sonic, biting him on the tail. Sonic immediately called Muttski a "bad dog", saying "You sit, you stay, you don't bite! Understand?" Surprisingly, Muttski immediately obeyed Sonic's instruction, presumably as a result of the four years of obedience school that Sonic had put him through. This allowed Muttski's original, friendly personality to reassert itself, and his eyes changed from glowing red to white. Sonic and Muttski were able to spend a happy but fleeting moment together, before Robotnik's programming again took hold and Sonic was forced to flee. Sonic vowed not to rest until he found a way to return him and all the other roboticized citizens to normal again. Muttski wasn't seen again since.
