Dark Witch (EntityTopic, 28)
From Compile Worlds
Dark Witch is an evil red clone of Witch, not to be confused with the Ekoro clone who once went by the same name. She is the final boss of Comet Summoner, and not much is really known about her, other than that she can go all Touhou on Witch's ass with her Cosmic magic. She is similar to Doppelganger Schezo in this regard, but her purpose is even more mysterious due to Comet Summoner not really having much of a plot.
