Illusion

Illusion is a material type in Kingdom Hearts II Final Mix. Illusion materials come in two variants, the Manifest Illusion (現れた幻影) and the Lost Illusion (失われた幻影).

Design
A Manifest Illusion is represented by a blue and cyan jewel. This jewel resembles two diamonds with concave edges stacked on top of each other. The lower diamond is slightly larger and has two spikes jutting from both of its upper sides. Two large, wing-like additives connected to the lower diamond's side corners. Both of these additives are angular and sport three "feathers".

A Lost Illusion is represented by a blue and cyan jewel. This jewel resembles two diamonds with concave edges stacked on top of each other. The lower diamond is slightly larger and has two spikes jutting from both of its upper sides. Two large, wing-like additives connected to the lower diamond's side corners. Both of these additives sport three "feathers", the topmost of which is twice as long as the others and has a pointed end, as opposed to the flat tips of the others. The base of the lower diamond is lined by four thin, conical spikes.

An "illusion" is anything that appears to be something that it isn't, and Illusion materials are only dropped by the Organization XIII Replica Data and the Lingering Will, none of which are the beings they seem to be. "Lost" reference the fact that the Organization XIII Replica Data bosses are copies of Organization XIII members that have already faded away. "Manifest" may reflect the fact that the Lingering Will was created by Terra's emotions manifesting in his discarded Keyblade Armor.
