Completed Fragment (完成した断片, Kansei Shita Danpen) is the unique class of Lyon as he appears in Disgaea X/Z, as well as all other cameo DLC.
Technically speaking, it first appears in the finale of Disgaea i, though as a modified title to the Great Destroyer? class Lyon wields in that game; only appearing prominently in the post-game. Only in later appearances does it acquire its own unique stats.
Like its predecessor, this class is based around the concept of a "magic brawler".
