Bizu is a member of the Sigma Force and a villain from Dragon Ball GT.
When Goku, Pan, and Trunks arrived on Planet M-2, Bizu, along with the other Sigma Force members, Nezi, Natt, and Ribet were sent to take them down by General Rilldo. They were successful in capturing Goku and Trunks, though they didn't take Pan.
After Natt's destruction, Bizu fused with Nezi and Ribet to become the powerful Sigma Force Cannon. However Goku easily manages to destroy them.
Bizu can fly and combine with his teammates into the Sigma Force Cannon. He has one special attack, the Bizu Barrage, which is when he pulls out two machine guns and fires at his target.
