MP Gauge

“	Special moves use MP. The MP you need for each move varies. If you don't have enough, you cannot use the move. You can recover MP by attacking opponents or waiting until your MP regenerates over time.	”
—Move List Description for MP.

The Hero's MP Gauge as shown by a Skill Preview in Ultimate.

The MP Gauge is one of Hero's fighter abilities.

Overview

The MP Gauge is a blue bar that appears over Hero's damage meter, displaying the amount of MP he currently has at his disposal. The maximum amount of MP available is 100. Each of Hero's special moves consumes a certain amount of MP and cannot be cast if the current amount is too low. The amount of depleted MP will appear as a green bar inside the gauge. The gauge will refill as time passes, at the rate of one point every second, or by damaging opponents with regular attacks, with an amount of MP recovered equal to the damage inflicted by Hero. Hero can also recover all of his MP instantly through one of the options from the luck-based Hocus Pocus spell.

If Kirby Inhales Hero he will also gain a fully functional gauge to use with Frizz; unlike other similar meters that can be copied by Kirby, the MP gauge can be refilled and doesn't force Kirby to discard the ability once it's depleted, therefore functioning identically to Hero's own gauge.

Origin

MP (Magic Points) are a mechanic from the Dragon Quest series. They determine how much mana a character can expend to cast spells. Each spell deducts from this pool at a set rate, and cannot be cast if the amount of MP is too low. MP can generally be restored by using particular healing items, but certain equippable weapons and gear and learnable abilities allow MP to be recovered through alternate methods, such as hitting opponents in battle or regenerating it over time, in a manner similar to how MP replenishes in Smash.
