Monster Fusion

Monster Fusion is a feature in Disgaea 4 that allows monster units to fuse together to make a giant monster that has larger AoE range. For example the Prinny's first ability Prillin Bomb that originally hits one space turns into a skill that hits a line of three spaces instead. The stats are determined by adding 30% of the monsters Base (Unequipped) stats to the monster you are fusing into unless you are using the fusion lover innocent where it uses 55% of the monsters stats. A evil symbol allows you to use 30% of a monsters Modified (Equipped) unless again you are using the fusion lover innocent which gives 55% instead.

To unlock Monster Fusion, the player must play Stage 1-3 first before the Fusion Command is unlocked.
