Uncle Chuck's Apprentice
Muttski was heavily changed due to the reality warping capabilities of the Super Genesis Wave. In this new world, Ben "Mutt" Muttski was a Mobian dog working as an assistant to Uncle Chuck. Sonic and Tails met him when they arrived in the Wood Zone to see Antoine D'Coolette, and were greatly surprised by the change in their old friend. Muttski and Chuck later fell victim to one of the tremors they were investigating, falling into a deep chasm. Fortunately, the trio of Freedom Fighters came to their aid, Antoine impressing Muttski in particular by chopping through several falling logs with his sword. Collecting their remaining samples of the strange energy they had found emerging from within Mobius, Mutt and Chuck departed for Spagonia to do further research. (StH: #254)
After Dr. Ivo Robotnik had launched a successful coup and began consolidating his power, Muttski and Chuck were captured and Roboticized during Charles' time running a Chili Dog Stand. Muttski remained an emotionless automaton until his liberation following Robotnik's death at Sonic's hands, and later Deroboticized by the Bem, coming to live with Sonic and Uncle Chuck, as well as Jules and Bernie, in Knothole. Muttski's bond with Sonic strengthened following his return from space, where, courtesy of the alien implant Sonic had installed to be able to translate alien languages, Muttski's normal inaudible woofs were translated into proper speech, allowing Sonic to communicate with him and understand responses. Following the destruction of Knothole, Muttski continued to reside in New Mobotropolis with Sonic's family, right up until the Super Genesis Wave changed the world.

Muttski originally didn't have much of a personality, being a normal dog. However, he became much more life-like in the Post-Super Genesis Wave reality.
- Muttski is one of several characters to originate from the SatAM cartoon show, where he appeared only in the pilot episode in his Roboticized form.
- When Muttski "speaks" while still a Mobini, he is shown to speak in third-person like: "Muttski is happy to have you home again." instead of "I'm happy to have you home again."
- It has been speculated that Muttski's post-Super Genesis Wave birth name is in tribute to the late Ben Hurst, the main writer of the Sonic SatAM cartoon series, of which Muttski originated.
