Bob Buoy is a scuba diver and submarine operator who works at the Aquatic Rescue Command Center (ARCC) with his partner, Gil Gripper. He is the leader of the ARCC and often acts as the operations supervisor during missions.
In the series, Buoy often says "Hoo-Ya! Victory is assured!" a cheer he proudly uses before, during or after a mission (more often after a successful mission).
