Corroder is a Villain that serves under Von Nebula's command.
In mid-2010, shortly after the capture of Rotor, Corroder invaded Penitentiary 1331 and fought off heroes Jimi Stringer, Dunkan Bulk and Mark Surge - and later, William Furno. He briefly escaped the conflict.
Corroder later arrived in New Stellac City, and fought the Hero Factory Alpha and Rookie Teams. After the capture of both Thunder and Meltdown, Corroder was quickly overwhelmed by Stringer's might, and stumbled to the ground. Later on, after the defeat of XPlode, Stringer and Bulk took a rusted piece of Metiosteel and tied it around the four villains. After the defeat of Von Nebula, the entangled villains struggled to escape, but obviously failed.
Corroder, however, was freed by a villain named Reaper that breaked into the center. Alongside their escape was Rotor, XPlode, Meltdown and Thunder. The crew escaped to Makuhero City, and were engaged in a battle there.
