The Mummy is the name of an Egyptian being introduced in Return of the Mummy
In Return of the Mummy, he rises out of his coffin to do what his ancient sister says. Though, he later dies after getting buried by a bunch of stones from the pyramid falling apart.
He then again appears in Don't Wake Mummy, where he is found by an Egypt scavenger, who then later donates the mummy to his family. Though, he comes alive once again and terrorizes the family, though he dies when his heart is destroyed.
