The Hamsters are all anthropomorphic and larger than normal hamsters. Bruce can be recognized by the dark patch around his right eye. Bruce started out as the most generic of the Adolescent Radioactive Black Belt Hamsters. He had no discernable personality, unlike his brothers Chuck, Clint, and Jackie, a fact which the writers joked about multiple times.
Eventually, Bruce became known as a car enthusiast and mechanic/technician.
Bruce and the others were originally mutated in the process of destroying a cloud of cosmic radioactive Jello for NASA. They were later trained in the martial arts by Tibetan monks.
When they returned to the outside world, they beat up a drug dealer and stole his money. Then they defeated a group of hijackers on a plane.
They landed as heroes, but they almost immediately lost this status as they got into a variety of scrapes in New York. Jackie, Clint, and Bruce went to a club. Later, they went on a moralistic tear throughout the city, destroying anything they deemed immoral, including the Statue of Liberty, which they thought was a giant half-naked woman.
They were caught by the police, and caused havok as they were processed into prison. They started a food fight in the mess hall, and eventually broke out. They met up with Chuck and fled the state.
They were playing video games in a mall when they got in a fight with a bully. He casually threw aside Bruce and beat up Clint, but Chuck finally beat up the bully. A professional wrestling promoter, Vincent DeLuxe, saw the fight and signed them up to fight the world champion Mighty Midgets as a tag team. The Hamsters became famous and were all over TV. Finally the fight started. However, the Midgets couldn't get to the arena on time, so they had to wrestle four huge guys instead. The Hamsters managed to win, and got DeLuxe to give them $5 million each because of the mix-up. Bruce bought a Ferrari, Mercedes, Porsche, and the 'Vette from Miami Vice with the money, and bought another car every month with the interest he got on it.
Driving an RV (which Bruce fixed up with various forms of advanced technology), they ended up at a toy store, where Jackie wanted to buy the new hot toy, Flower Garden Folks dolls. However, the dolls eventually went crazy and tried to kill everyone. The Hamsters managed to destroy the dolls and rescue their maker.
They drove across country and stopped in a rural area. Jackie ran off, thinking he was a WWI Flying Ace, and Bruce, Clint, and Chuck got into trouble in a convenience store. They were arrested, and then they were waylaid by the C.C.C., or Coo Clucks Clan, a religious/racist cult who worshiped Colonel Sanders and dressed up like chickens. They prepared to cook the hamsters over a cauldron.
Meanwhile Jackie ran into the Heap, who helped him find the others (although they destroyed the RV on the way). With the help of the Heap, they quickly routed the C.C.C. and escaped.
They next ran afoul of the P.L.O. again. Bruce and the others fought against the villains, but had a hard time until Captain Tree and Bush Boy arrived and saved the day by sacrificing themselves in the act of killing the P.L.O.
In one out-of-continuity story, Bruce got a magic saxophone that attracted women. However, it ended up only calling dogs. He got a new magic sax, but it only called giant female lizard monsters.
After many other adventures, the Hamsters battled the villain Infidel Castro. Bruce was tied up underwater and killed with a harpoon. The others brought him back inside the underwater base, but couldn't restore his heartbeat, and went out to mourn. However, a strange creature broke out of a nearby pod and worked on him, somehow restoring his heartbeat. He then locked the door, set the base's self-destruct mechanism, and, one supposes, took his body with him. The other Hamsters escaped the base, but were separated by the explosion, seemingly forever. The original series ended here.
The 2008 series retconned much of the last issues of the original series. It simultaneously explained the Infidel Castro arc, and Bruce's death, as having been both a dream and having taken place in an alternate dimension. Whatever happened, the new series started off with five new Hamsters ( Lucy, Jean-Claude, Steven, Arnold, and Rock) constituting an all-new team, and with the original four split apart--although in a different way, and for different reasons, than the split seen at the end of the original series.
The series starts off with the invasion of the monastery by a villain known as Genghis Khann. All of the new Hamsters are killed or captured trying to defend it except Lucy, who escapes and manages to reach Master Lock. Lock then contacts Jackie, who has been living with a group of samurai and mystics underneath Mount Fuji. Jackie has been training intensely, and misses his brothers, so when Lock lies to him and tells him they're all waiting for him so they can all recapture the monastery, Jackie is glad to come.
When it turns out that they are still split up around the world, Jackie and Lucy fly off in their jet to find them. Bruce and Chuck have not been taking care of themselves nearly so well--they are overweight and look middle-aged. They have been working together for some time in Texas, hunting Chupacabras, but haven't seen Jackie or Clint in years. Bruce rides a robot horse, and Chuck rides a normal horse. Bruce now says "reckon" a lot, and Chuck has a sheriff's badge and goatee. Bruce has a refrigerator built inside his horse, and they like to take a load off, drinking chilled root beer around the campfire.
While they are reminiscing about their brothers, a Chupacabra catches them and ties them up in her cave. She wants to mate with them. When Bruce wakes up, he's still thinking about his "dream" about Infidel Castro. They manage to get down and fight the Chupacabra, showing the good old teamwork and banter. However, they are out of shape, and are not winning. Jackie rappels down and saves the day, quickly dispensing with the beast. Bruce and Chuck are embarrassed at how much better shape he is in, but Jackie is so glad to see them he doesn't care. They are happily reunited.
Meanwhile, Khann has been working on a secret plan. He somehow resurrected some of the new team of Hamsters and brainwashed them into working for him. He finds a computer room under the monastery which is tracking a cloud of cosmic Jell-o, just like the one that first mutated the original Hamsters. Then he and the zombie Hamsters catch Master Lock and get the codes to use the computer room.
Jackie, Bruce, and Chuck find Clint, who has also been living a very different lifestyle. He is now the doormat husband of an overbearing human wife. He works in a pawn shop. Jackie, Bruce, and Chuck come in to get him on the team again, but he pretends he doesn't recognize them. He is so stuck in his new pathetic life that he can't bring himself to admit that it was ever different. They all talk. It turns out that Clint was in love with Lucy, but she had a relationship with Chuck instead. The affair (which they liken to Yoko and the Beatles) made them all crazy and broke them up. Bruce understands the motivation to start all over, and gives him a hug.
Clint refuses to understand any of this and kicks them out. Clint's neighbor, Richard, sees them and invites them in, but it's a trap: he's a sex fiend obsessed with animals. Lucy finally finds Clint and knocks some sense into him, and the two of them rescue the others. The brothers want to set off to save the monastery, but Clint says no--he wants to go back to his family; as horrible as they might be, they need him.
Without Clint, the others invade the monastery and are caught. Khann brags about his new plan to them, and points out the incoming cloud of space Jell-o. Then, without further explanation, he shoots Master Lock, Jackie, Bruce, Chuck, and Lucy in the head, killing them. It turns out that the cosmic Jell-o is the home for many other Hamsters, who are apparently alien, not mutant, in origin, and Khann uses them to take over the Earth. Clint eventually tries to get revenge on Khann, but fails, leaving Khann in complete control.
Powers and Abilities
Like the rest of the Hamsters, Bruce is a skilled martial artist. He sometimes uses a bo staff.
He is also a skilled technician, able to fix cars and alter electronic equipment. For instance, he created a car GPS unit in the 1980s! He was also able to build a robot horse with a refrigerator inside.
He lost a lot of his skills over time, and while he could still fight in his later years, he was no longer in his prime.
