Your Transformers adventures just got a whole lot bigger! Your Stomp and Chomp Grimlock figure is a giant, 20-inch robot with a mighty sword who's ready to take on any enemy. He changes in 1 step to a dino with a terrible, chomping jaw and light-up eyes! Team him up with the included Optimus Prime mini-figure for maximum mayhem. Power Battlers and One-Step Changes figures (sold separately) activate different lights, sounds and weapons, and his weapons pop out for battle! Which mode will you put him in for the most awesome Transformers action? It's up to you to decide!
