Character Description and History
Rock is named after The Rock, the action hero. He is one of five members in the new team that replaced the original Adolescent Radioactive Black Belt Hamsters. The other members of the new team are Arnold, Lucy, Jean-Claude, and Steven.
He is an anthropomorphic hamster from an alternate dimension, but was eventually brought to the dimension where the original Hamsters lived. He is fairly heavily-muscled, although not as much as Arnold. He has black hair on the top of his head. He is the most argumentative of the Hamsters.
When we first see him and the other new Hamsters, they are training in their headquarters in Chicago. They receive a psychic message from the Dalai Momma, the head of their monastery. She warns them that the monastery is under attack, and begs them to return (although she does call them her "second-favorite students"). Rock doesn't want to go, believing that if the monks don't care about them, they shouldn't care about the monks, but Jean-Claude and Steven persuade him that they must help. The Hamsters get in their jet (a B2 Stealth bomber) and fly to the Himalayas. Jean-Claude and Rock continue to bicker about the monks, who used to always ask, "what would the Four do," in reference to the original team of Hamsters. Basically Rock is jealous of the original team.
They land, and are attacked by Genghis Khann and his army of Huns. Steven and Jean-Claude are killed. Arnold is taken down. Rock is quickly covered in a pile of Huns. It is unclear whether he and Arnold are captured or killed. Lucy is thrown off the edge herself, and eventually manages to find their old Master Lock, who helps her contact the original team of Hamsters.
Later, we see Khann leading Arnold and Rock down into a hidden room below the monastery, which holds a giant computerized navigation system. They are clearly under his control somehow, but the situation is ambiguous. Were they killed and resurrected? Did he brainwash them? It is unclear, but they are completely on his side now.
We next see them, along with the previously-deceased Jean-Claude as well as the Hun army. (For some reason, Steven doesn't get resurrected.) They attack Master Lock and his small team of Abominable Snowmen, and defeat them. Then they help Khann torture Master Lock to get the password to the computer room.
Later, when Lucy and the original group of Hamsters attacks Khann and the Huns, they are defeated, probably with help from Arnold, Rock, and Jean-Claude, although the battle takes place off-panel. Khann then kills the original Hamsters (except for Clint, who isn't there). Soon after, Khann takes over the world, using an army of other hamsters that arrive via a cloud of cosmic Jell-o. Presumably Arnold, Jean-Claude, and Rock remain as his accomplices.
Rock is a gifted hand-to-hand combatant, like the other Hamsters.
