In the Marvel Comics adaptation of the god, Thor usually relies on his hammer to fly. However, in situations where he must transport passengers and/or objects, Thor can summon Tanngrisnir and Tanngnjóstr, who arrive already harnessed to his chariot, and can be dismissed with equal ease. The two goats were vital in a later Marvel Comics story; they believed a tale of danger to Odin and summoned reinforcements. They later made sure various Asgardian children were safe when an invading army threatened.
