Wait, in the series one guy became a crab for eating too many crabs, one guy turned into a monster (first OVA) for being a crime boss and his monster form represented his personality…

…Are we to assume King will obtain the ability to live life as a video game?

In my opinion, his ability to intimidate enemies to the the point of surrender is an absolutely fantastic power. He just can't take full advantage of it due to the fact that he himself is paralyzed by fear.
