Mum-Ra, often written Mum-Rá in Portuguese, is the main antagonist of ThunderCats, the animated series that premiered in 1985. The character is an ancient undead sorcerer who serves dark forces and transforms into a stronger form when he calls on them. Clips of his voice have circulated for years in cartoon compilations and meme edits, later appearing on soundboards as short shareable audio. This version circulated with a credit to Marcellus and JogoPelado, and its longer dramatic delivery keeps it popular for nostalgic and parody edits.
