Cresselia

Cresselia is a female Legendary Pokémon that originates from Pokémon Diamond and Pearl Versions. In the Super Smash Bros. series, she appears as a background hazard in the Spear Pillar stage, along with Dialga and Palkia, in Super Smash Bros. Brawl and Super Smash Bros. Ultimate.

Whenever Cresselia appears on the stage, she shoots a boomerang-like energy blade, which spins around the stage and hurts any fighter that it hits. Sometimes Cresselia uses Psycho Cut, which sends a sharp beam straight down the center of the stage.
