Hamster (possibly Hamster Grant-Gomez) is one of the titular protagonists of Hamster & Gretel. He is the pet hamster of Gretel. He and Gretel have been bestowed superpowers by aliens and instructed to use them for good. Their superhero personas are kept secret for mostly everyone, including Gretel's parents Dave and Carolina. Gretel's big brother Kevin, their cousin Fred, their grandmother Abuelita Gomez, and Gretel's best friend Bailey are among the only people that know about their secret identities.
Unlike his owner, Hamster is more mature and collected, knowing exactly what to do in most situations. While Hamster is given the ability to talk, he's often quiet and doesn't emote much beyond a bored expression. When he does talk, he tends to quip about the current situation in a somewhat jaded tone.
