Dad

Dad is a character in Disgaea 2: Cursed Memories who is the father of Taro and Hanako, and the husband of Mom. "Dad" is in fact his real name.

Dad is a Zombie-type Demon, but doesn't have a rotten smell. He also has a strange face-like creature attached to his chest. The creature not only wishes he would be more aggressive but is very perverted, often spouting suggestive comments. It may be a reflection of his subconscious.

At one point in the game he switches places with the creature having his "Dad" Persona inside his chest and the "Creature" Persona in control of his body, running amok and doing perverted things.
