Transform yourself into something powerful when you take on Halloween in this officially licensed classic Transformers child's muscle Ironhide costume featuring a muscle torso and arms. Ironhide is one of the oldest and toughest Autobots and is the resident weapons expert. He's been on Optimus Prime's team for a long time. "They don't make them like they used to" is an apt description of Ironhide—he's yesterday's model, but he's built to last.
