"I've been waiting for this moment..."
- Bowser at the final battle atop the Halberd.
Bowser, also known by Blue team as The Traitor, was a brilliant, brutish, and contemptuous giant koopa, and he was once a member of Blue team. He was known as the big lug who looked tough on the outside, but really was a very nice guy. He was often used as the guy to bear weight, and to do menial, manual tasks and labor. However, he eventually became fed up with his menial role in the Team, and betrayed them.
Using his incredible intellect, he planned out an ingenious plan to betray them. He also became head of the Koopa Troop, an organization of Koopa soldiers and mercenaries, as well as a joint force with Eggman's robots, with which he waged war upon Blue team during the event known as The Hunt. Bowser is now known by the team as The Traitor, and he was responsible for the deaths of a tragic number of Blue team members.
