"Fusion! Fusion! Haha! Jeder ist glücklich, wenn ich fusioniert werde!"
This subspecies of Metall-Gespenst is said to have changed after having amassed extensive records on the element of light. It is called the most unlucky of the metal record species, and not just because of the amount of knowledge it holds within itself, but also because of the various things that come out of its mouth. The element of light is much stronger in them than in normal Metall-Gespenster, and it's said that when fused to other light types they provide loads more experience as well.
Light Ghosts are best used as an ingredient for fusion, providing a base of 1,506 XP. When fused with Light element units, it grants 2,259 XP, not including Great Success (x1.5) or Super Success (x2). The Light Ghosts only sell for 1,000 Zel each.
