The set's box

The set consists of 40 pieces.

There is a non-canon combination model made of parts from this set and 7147 XPlode. It was named "Crunchy" by webmaster Kelly McKiernan, who designed and only used the model as an example of a Hero Factory creation in's Gallery page, in the Prototype Photography Tips section.[Prototype Photography Tips] Instructions for it were never released.


The set features a Meteor Blaster, which is connected to the top of Corroder's right upper arm. The Blaster can rotate around its place. The set also has the two Acid Blasters, which it has for hands. The Blasters also allow Corroder to stand on all fours. The set has another one of the Blasters for its back armor.

The back of the box shows Corroder's stats.


The set includes a lime green helmet. The Blasters and back armor have various stickers.


  • Corroder is the only villain in the 2010 set year to not be a hunchback.
  • Corroder's arms are the same as the limb pieces from Bionicle's 2008-2010 sets.
