Heart Points, which are abbreviated as HP, are points used by all characters in battle. It is depleted when a character is attacked. They represent the character's life force; if it runs out, the character is defeated. Items such as the Mushroom can be used to restore these valuable points, and the item Life Shroom can cancel the effect of defeat. Max HP can be anywhere from 10 to 50 (65 if you wear HP Plus Badge) (Paper Mario), 5 to 200 (365 in theory if badges are provided) (Paper Mario: The Thousand Year Door), 10 to 255 (999 in theory if items are provided, however, doing that needs 1,117,500 coins in total) (Super Paper Mario),or 20 to 100 (Paper Mario: Sticker Star).
