|Occupation||Leader of the Renegade Brawlers|
|Guardian Bakugan||Adumbration Dragonoid|
Sirius is a calm, cool, and collected character, but has many evil intentions. He is deemed insane by several of the New Battle Brawlers because of rumors that he had used live Bakugan in dangerous experiments. He can get stubborn, though it is very hard to make him stubborn. He also seems to fight fairly in battle, but will happily pull out something that will gain him the advantage that is not allowed.
