Decus

Decus's special ability grants him the ability to change forms and look like anyone else. He uses this ability to transform into Lloyd and attack Palmacosta. This is the reason for Emil's hatred toward Lloyd though it was actually Decus. After the collapse of the Vanguard, Alice and Decus begin working with Richter in order to gain power. In the final dungeon you must fight Alice and Decus and after beating them there is a cut scene where Decus throws himself in front of Alice to save her life and just before he dies she reveals that she loved him and then she to gets killed.
