Overhaul is an Autobot warrior, having fought alongside Optimus Prime during the Unicron Battles and Powerlinx Battles, and likely before that, as well. He is gruff and oftentimes confrontational, but is exceptionally loyal to the Autobot cause regardless. He says he prefers to work alone, but knows deep down the values of friendship and teamwork. He is the cousin of the Decepticon Brushguard.
