Fire Scorpion is a special Bakugan Trap. Its massive claws can clamp down on its opponent and thrash them about. The hard armor that covers its body is extremely light, allowing Fire Scorpion to move quickly.
It was released in Dan's Combat Set together with a normal Pyrus Ultra Dragonoid. Fire Scorpion has a button on its head. You pull back the tail, it clicks, put a Bakugan in front of Fire Scorpion's face, then press the button on its head. It releases the tail, shooting the Bakugan onto the Gate Card.
