Although the character was redesigned to some extent, like the other characters in the film, many classic design elements remain in his robot mode including a predominantly red torso, primarily blue legs, the presence of windows in his chest, smoke stacks on his shoulders, and a head design influenced by the original, featuring the iconic faceplate and ear finials. The faceplate is able to retract to reveal a mouth.
