Dino Mammoth is a Woolly Mammoth transformed by the planet into a Dino Knight to defend Earth against the Dragozaurs, standing out as one of the few non-dinosaur members. He serves as a highly competent, reliable, and level-headed warrior within the team, valued for his formidable combat abilities despite lacking speed. He wields the Mammoth Tusks of Vigor, also known as the Big Tusk Spear.

During a mission to the Arctic with fellow Dino Knights to confront the Dragozaurs, Drago Wing shrunk him using a device; his normal size was restored only after the destruction of the Dragozaurs' life force extractor. Uniquely, Dino Mammoth possesses psychic abilities, granting him prophetic insights into events like those concerning the legendary Dino Ramph. His role emphasizes stability and resilience, contributing crucially to the group's mission of safeguarding Earth's life force without seeking personal glory or leadership.
