Paper Mario: The Thousand-Year Door
In Paper Mario: The Thousand-Year Door, the term "Danger Mario" refers to an exploit where the player decreases Mario's max HP to 5, and proceeds to equip multiple Power Rush badges, which can be obtained at the Pianta Parlor. This would make Mario virtually invincible and able to end any fight in one turn. Because this exploit would make the game easier than a casual playthrough, the Danger Mario challenge does not exist in this game.
