Corroder

LEGO 7156 Corroder is a HERO Factory Rise of the Rookies set released in 2010, containing 40 pieces. It builds the Corroder villain as a poseable buildable figure with razor claws, a spiked head, and a Meteor Blaster accessory. The character concept includes corrosive spit and the ability to run on all fours, allowing aggressive charging poses with the spiked head. Released in the launch wave of HERO Factory, it represents the early constraction design style used across the theme’s initial villains. It was retired in January 2012 with a lifespan of 18 months.
