Doppel

Doppels are ghost-like creatures found in Smithy's Factory during the events of Super Mario RPG: Legend of the Seven Stars. In battle, these enemies fight alongside Lil' Boos, Glum Reapers and Puppoxes. Like most ghosts, Doppels have an extremely low physical defense while having a relatively high magical defense. Doppels are very fast and attack with a variety of ghost-type moves. It is unknown what connection this ghost has with the Smithy Gang. A related enemy called Shadows are found in Kero Sewers.

Trivia

 * In German, "doppel" means "double." As such, Doppel likely gets its name from the term doppelgänger, an English loanwaord from German that means ghostly double.
