The Lucidon is an enemy in Final Fantasy XIII.
This foe uses Photon Burst to launch opponents into the air. It resists damage and is immune to all debuffs when its carapace is intact. The only way to deal significant damage to the Lucidon is to stagger it.
The first part of the Lucidon's Japanese name, Schildpatt, is derived from the German word for "tortoise shell."
