Corroder is one of Von Nebula's most intelligent servants.


Von Nebula recently recruited Corroder as one of his newest villains. In that time, he committed theft from numerous planet treasuries, destroyed public monuments on several worlds, & sabotaged the Cygnia Thermo-Dam.

Under Von Nebula's instructions, Corroder attacked the construction site of Penitentiary 1331 on Tantalus 5, wounding some of the workers. Heroes Jimi Stringer & Dunkan Bulk were sent to fight him. As Rookie Mark Surge arrived, shooting lightning at the villain, Corroder blasted acid at the girders above him. The metal collapsed, falling towards Surge, but Bulk pushed him out of the way and took the blow for him. The Heroes linked cores to form a Hero Cell, protecting themselves from Corroder's attacks - to the villain's frustration.

A Hero Pod then crashed into Corroder, angering him even more. He stomped towards the pod, intending to tear the Hero inside apart when he got out. However, Rookie William Furno then attacked him, revealing that he had jettisoned from the pod before it crashed. Corroder shot acid at Furno, but the rookie had been retrofitted by Big Joe with acid-resistant armor. Corroder then noticed a Drop Ship arriving, & Furno asked if the villain could take on ten Heroes at once. Corroder decided he could not, & formed a smokescreen by stirring up the dust. He then escaped, returning to the villains' base. There, he reported to Von Nebula on how the sabotage had gone. Von Nebula revealed that Furno had bluffed, but that Corroder had still been successful in his mission.

Corroder & Thunder were next sent down to New Stellac City in meteorite-like capsules. There, they battled the Alpha 1 Team. The rookie team eventually arrived to aid the Heroes, but so did XPlode & Meltdown to aid the villains. Von Nebula created a black hole to suck up the Heroes' weapons, & Furno & Stormer leap in to combat "The Mastermind". Meanwhile, the rest of the Heroes used Particle Separators to evade the villains' attacks. Corroder & the other villains soon ran out of ammo, & Corroder was stunned by Surge & Breez working together. Bulk & Stringer then twisted a heavy metal bar to hold the four villains captive.

Sometime in prison after the events of Savage Planet, Voltix used Von Nebula's essence to shatter the Black Hole Orb Staff to create a vortex allowing Corroder & all the other villains to escape from the Hero Factory. He is still on the loose.


Corroder is an intelligent individual, but does not appear to be a wise one. Lethal in close combat, Corroder thinks he should lead the group, instead of Von Nebula. However, Corroder is smart enough to not rebel against his boss unless he is sure he can defeat him.


Corroder has lime green & black armor & orange translucent eyes. He also walks on all fours.


Corroder was armed with Razor-Sharp Claws & a shoulder-mounted Meteor Blaster. He is also known to use his corrosive spit & his horn in lethal combat.
