Optimus Prime is the most famous Transformer and certainly the most dynamic. The leader of the Autobots packs a powerful punch while defending the Earth from all of the Decepticons. The Boys Muscle Transformers 3 Optimus Prime Costume features a red and blue jumpsuit that has printed robotic/machine detailing across the entire suit. To resemble the large frame of the Transformer, there is muscle padding in the torso and arms. The mask to the costume is the finishing touch. The mask looks exactly like Optimus Prime's from both the TV series and the movies. The mask is blue with a silver plating in front of the mouth that extends upwards. This replicates Optimus Prime in his Autobot form, though you can still vaguely see the resemblance to an 18 wheeler. Wear this to a costume party to be easily recognized and have the most powerful costume at the party.
