Firebrand and Thunderhand

Firebrand and Thunderhand are two beings (described as genies or guardian spirits ) that inhabit the Fire and Thunder Palaces. In Mario & Luigi: Superstar Saga, Firebrand teaches Mario the Firebrand technique, while Thunderhand teaches Luigi the Thunderhand technique. They wear white cloaks and are capable of floating in the air. Firebrand's head is the top half of a sun shape, and Thunderhand's head is shaped like a crescent. Firebrand is forgetful and easygoing, in contrast with Thunderhand's no-nonsense attitude. Both always appear with a flash of their respective element.
