Dora the Kid is an American robotic cat patterned after the Doraemon model, featuring distinctive yellow skin and ears. He upholds the law as a sheriff's deputy in Texas, USA, with certain adaptations placing this role on a Western-themed planet. He operates under an old sheriff captain, working alongside the captain's granddaughter, Anyi, while secretly serving as an agent for the Time Patrol Police.

His skills include proficiency in quick shooting, though he suffers from acrophobia, a significant fear of heights. Lacking fingers, his primary gadget is the Air Gun mounted on his arm, firing powerful blasts of air from its revolver-like muzzle. He stores essential items not in a pocket, but within a four-dimensional hat worn on his head.

Socially, Dora the Kid often considers girls troublesome yet exhibits romantic behavior in their presence. This is particularly evident in his interactions with Dorami, where mutual affection exists. His culinary preference involves adding ketchup and mustard to dorayaki, creating a hot dog-like dish.

Within the Doraemons group, he embodies American patriotism. His background includes training at the same Robot School as Doraemon, utilizing the Friendship Telecard to summon fellow members during crises. Dora the Kid's personality blends a rugged Western exterior with moments of sweetness, especially in romantic contexts.
