Bulk attended Angel Grove Elementary School with his best friend, Skull, and also the kids who would later become Power Rangers. Bulk became best friends with Skull after an incident where the former decided to not beat up the latter for shoving a popsicle down his shirt. Many years later, Bulk and Skull became bullies at Angel Grove High School, often hung out at the Youth Center and Juice Bar, and their actions were motivated by greed and egos. One day, they even discovered the secret identities of the Power Rangers because they had saved the Rangers when the Ranger team lost their memories and were de-morphed in front of them. A few weeks later, they joined the Angel Grove Junior Police Force and first met Lieutenant Jerome Stone, they eventually put a stop to their bullying ways. Lieutenant Stone was giving Bulk and Skull orders that they failed to perform, leading eventually to his anger, which caused him to be fired by the police chief. Bulk and Skull quit the force and joined Stone when he opened his own detective agency, and took an undercover mission in France. After Bulk and Skull had returned from France and reconciled with Stone, all three eventually got a chance to rejoin the Police Force. Lieutenant Stone worked there for a few more years until, he officially retired and took over the Angel Grove Youth Center. However, he still owns the detective agency, where he has a lot of assistants help him with missions and cases. Meanwhile, Bulk and Skull were spending their time helping the rather loony Professor Phenomenus, helping him locate and capture extraterrestrial life. Several months later, Bulk and Professor Phenomenus boarded the space station bio-dome Terra Venture for its interstellar journey to a new world, in order to finally get away from all of the monster and alien attacks that had been going on recently. Skull, however, did not wake up in time and was left behind. While on this new planet, Bulk and Professor Phenomenus ran the Comet Cafe on Terra Venture. A year later, Bulk returned from Mirinoi. Eventually, Bulk and Skull decided to open their own business, where they became servers and managers of a tropical-themed bar called "Bulkmiers".
