Mammoth first appeared as a founding member of the Fearsome Five (which is a group of villains determined on defeating the Teen Titans) and became an enemy of The Titans, Superman and The Outsiders (which was a group created by Batman that were formed as an alternative Justice League which didn't need political or public approval for their actions.) He is highly devoted to his sister Shimmer who was also a founding member of the Fearsome Five. Mammoth was a massive man with immense strength and durability not capable for a regular human. Mammoth is emotionally and intellectually underdeveloped (so much once that he was tricked into surrendering to Superman who at the time was powerless thanks to Lex Luthor using Mr Mxyzptlk's red kryptonite. He also lacks skill in hand to hand combat.
