- "Let's see how tough you are after a little acid, Hero."
Corroder's claws consist of six parts, he has two of them on each hand, and two on his back. His legs are made from Ben 10 thighs, Toa Metru legs, and shadow Matoran feet. Corroder also has a Meteor Blaster strapped to his arm.
Corroder was a servant of the evil Von Nebula and one of his newest henchmen. His weapons were his corrosive spit, the razor-sharp claws and his favorite weapon, his horn on his forehead. His quote is "Let's see how tough you are after a little acid, hero.". He used a vehicle used by most of the Villains. He summons it using a small car key device with a keyring bearing a model of his head. He had an evil cackly voice, and was persistent in his fighting, as seen when he fought Dunkan Bulk, Jimi Stringer, Mark Surge and William Furno. It is presumed he did this for sport.
- Corroder is voiced by Charlie Adler
