Tretorous is a slow moving, lumbering Bakugan. Like his partner Lightning, Tretorous appreciates the value of a good nap and is often found slumbering instead of battling.
Tretorous is described as lazy and sleepy, he prefers to relax instead of battle. Even when he's battling, he doesn't try hard and tends to give up easy.
