The Curse of the Mummy, also known as Mummy's Curse is a deadly disease that slowly degrades its victims by making them crumble to dust. The curse doesn't exactly kill it's victim per say, as according to Dr. McNinja their molecules remaining alive and sentient, and would scatter across the world, the victim will end up everliving with no facility at all.

Two people were known to have contracted it: Mitzi McNinja and King Radical, both of which were cured of it by Dr. McNinja, though the second time he was posing as Dr. McLuchador to infiltrate Radical's gang.
