Corona

Corona is an attack most often used by boss enemies in Super Mario RPG: Legend of the Seven Stars. When used, Corona will summon a large, yellow orb which will attack all members of Mario's party, doing significant damage.

Trivia

 * Corona means "Crown" in Spanish, and the corona is also the extended outer atmosphere surrounding the sun and other stars. Either, or perhaps both, of these could be where the attack gets its name.
 * In Super Mario Sunshine, the volcano is named Corona Moutain.
