The Furiferi (フリフェリ?) is a mayfly-like Reaverbot that appears in The Misadventures of Tron Bonne. This Reaverbot is only found in the Nakkai Ruins and seems to appear out of nowhere. They are similar to the Foo-roo since they come in groups and attack by floating into their targets and will easily explode with the slightest bit of damage is inflicted to them. Along with the large Sharukurusus, golden Furiferis come out of the Colossus.
Enemies similar to the Fuyuu.
