Ben Muttski

MuttskiMeister (nicknamed Muttski) is Sonic's loyal pet dog, who like Uncle Chuck was roboticized prior to Sonic joining the Freedom Fighters. Muttski is almost exclusive to the Archie comics, only making a brief cameo appearance in the SatAM pilot episode Heads or Tails wherein Sonic encounters him during a mission to Robotropolis, managing to spend a fleeting moment with him during a short lapse in the mind control inflicted on all roboticized beings. Once Muttski was back under Robotnik's control, Sonic vowed not to rest until he found a way to return him and all the other roboticized citizens to normal again.

In the comics, Muttski was one of Sonic's more feared antagonists, because Sonic did not wish to harm his faithful pet. Eventually, Muttski was freed from Robotnik's control, and took up residence in Knothole, once again becoming Sonic's close companion. Like all of the roboticized Mobians except Jules Hedgehog and the partially roboticized Bunnie Rabbot, Muttski was deroboticized by the Bem. An interesting development: during Sonic's time spent in space (six weeks to him, a year to everyone else) he received an implant that allowed him to understand and speak to aliens. Back home, the implant now allows him to speak with Muttski and understand what he's saying. Muttski's abilities are those of the average dog, though his speed and strength were enhanced by his robotization. Muttski's closest friend besides Sonic is the hedgehog's adoptive "brother" Tails. This is proven true when the two spend a day together.

Around the time Robotnik took over, he captured Muttski and roboticised him. He now wanders around Robotropolis as a slave dog. A medium-sized roboticised dog. His body is grey and black. His eyes are purely red (when in normal robotic mindset) or yellow (when reverted to his normal personality). His teeth are very sharp giving him quite a bite, and can also shoot objects from his mouth (after chewing them). He's roboticised so he has turned against the ones he loves. He is capable of temporarily breaking free of his robotic programming without the aid of a power ring. This is possibly due to extreme loyalty to Sonic. He was Sonic's pet.
