Erdrick

Erdrick is a recurring legendary hero from the Dragon Quest series, and specifically the playable character of Dragon Quest III. The first three Dragon Quest games are called the "Erdrick Trilogy", as each relate to the character of Erdrick in some way. Although they do not appear in Dragon Quest or Dragon Quest II, Erdrick is mentioned heavily in the game dialog and many items bear their name.

Erdick has a unique mechanic known as "Psyche Up," which is comparable to Cloud's Limit mechanic. The more he charges, the higher tension he has, which boosts the power of special attacks. Credit: https://gamefaqs.gamespot.com/boards/234547-super-smash-bros-ultimate/77173312
