Rattleoid is a rattlesnake-like Bakugan.
Rattleoid is a slithering rattlesnake with a three-pronged metalic tail. Two large fangs release a lethal poison. Indestructible golden horns on its head with bright red eyes are used to hypnotize its opponents. It uses the strategy of camouflaging itself during combat.
