Ignis Fatuus

Ignis Fatuus was a clone of Eidolon created by Echidna. He shared his powers and memories, but, like all Echidna clones, felt a driving desire to destroy everything his original cared about. He was only named in the chapter tags.

The term ignis fatuus means a will-o-the-wisp - a malevolent ghost that leads travellers astray - or more generally something that misleads or deludes; whereas "Eidolon" means an idealized image or phantom of a person.

The clone displayed a "flickering" ability much like Grey Boy's, which he used to conjure costumes for himself and Apocrypha, as well as to heal injuries.
