Be Cool, Scooby-Doo![]
Season two[]
Big Head managed agent Jenny Vex as she broke into a food science lab and stole a thumb drive. However, Vex was attacked and captured by Minus, an operative working for their enemy, Bubby. Despite the mission being a failure, Big Head forbade the gang from pursuing the mission, insisting it was too dangerous. However, they did not obey his command, locating Minus' next target, Dr. Itsuki Himura in Istanbul.
Once the gang rescued Vex and foiled Bubby's plans, Big Head appeared to capture Bubby, Minus, and the remaining henchmen (the Sweatermen). Afterwards, he tasked the gang with a larger-scale mission.
