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 that will attack all members of Mario's party, doing significant damage.
"Corona" means "crown" in Spanish and Latin, 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.
