Pearl Jam is the main antagonist of the animation. He is a confident fighter with an incredible amount of strength. Not only that, but he wears gauntlets that are like claws, and a head piece that acts like a canon, giving him a major advantage in battle. He has a overwhelming sense of pride and a large ego to top it off. However, he has respect for worthy opponents and will go all-out with someone on his skill level.

Pearl Jam's voice is rough with a low pitch. He should also speak with confidence.
