This subspecies of Metal Ghost is said to have changed after having amassed extensive records on the element of fire. Known for their offensive way of speaking, they constantly vilify Summoners they come across before quickly running away. Because of this they are rarely seen, but they're also hard to forget. The element of fire is much stronger in them than in normal Metal Ghosts, and it's said that when fused to other fire types they provide loads more experience as well.
Fire Ghosts are best used as an ingredient for fusion, providing a base of 1,506 XP. When fused with Fire Element units, it grants 2,259 XP, not including Great Success (x1.5) or Super Success (x2). The Fire Ghosts only sell for 1,000 Zel each.
