Character History
Sheldon Mavis was experimented on and turned into his monster form.

Metal-Grinder appeared and attacked Tommy Landers and Jason, grabbing Jason and trying to take him away, presumably back to the facility. Jason fought back without success, but Tommy transformed into Kamen Rider Max HopperTanker and fought it. He briefly took SpikeTanker before returning to HopperTanker and defeating the S.L.A.M with Final Break, extracting the S.L.A.M essence with a blank Full Bottle. Questioned by Jason, Metal-Grinder claimed to remember nothing, escaping into some tall grass as a squad of Sentinels arrived.
