Slicer first appeared as part of a team-along with Coconuts, Crabmeat, Buzzbomber, Newtron, and Roller-to break up the apparent wedding of Sonic the Hedgehog and Sally Acorn. Despite being armed with sharp blades, he was defeated along with his fellow Badniks, and the wedding was revealed to have been part of a play. (StH: #18)
Appearing During Genesis
A group of Slicers were guarding the Metropolis Zone when Sonic tried to get past them during his mission to get to the core of Eggman's base. It is unknown if Sonic destroyed them or simply passed them. (StH: #229)
- The Slicers that appeared during Genesis in Sonic the Hedgehog #229 resembled the design of the Slicers from the video game Sonic the Hedgehog 4. When they later appeared during Sonic the Hedgehog #255, they seemed to be much bigger. Also, in one of the panels in that issue, a detached Slicer's head can be seen in a battle scene where it is all grey with no details and red eyes with no pupils.
