Shadow

Shadows are powerful black phantoms that reside in Kero Sewers in the game Super Mario RPG: Legend of the Seven Stars. In fact, Shadows are the strongest ghost found in Kero Sewers (the weaker ghosts being Hobgoblins and Big Boos). Shadows usually fight in groups of two to four, although they never fight by themselves; they only aid other monsters in battle, either fighting alongside Rat Funks, or with their undead brethren. Like Boos, Shadows have the ability to hover in the air.

In a fight, a Shadow will pound Mario's allies with its massive forelimbs, or shoot a physical energy blast at a party member. Additionally, these phantoms know the special attack Endobubble, inducing the Fear status ailment in one party member, thus cutting the character's attack and defense in half. A Shadow's yellow eyes always flash red when they are attacking. Since they are undead, Shadows can be instantaneously destroyed with Pure Water.

Shadows are related to the Doppels found in Smithy's dimension.
