CEO of that one huge prison in the underworld... He's ruthless and doesn't like being talked back to, always has to have the last word, always has to be the one who's right. Maybe this way of living helps him assert his domninance, but it just holds him back from fully living his dad life (dada life LOL). Demons ARE known to be cold, but shouldn't a father change his ways to adapt to his child? Well he didn't do that to Devi... He actually has a very complicated relationship with him, he hardly thinks of him as a son. but that's a story for another day.
