Two Heads is a solitary spirit, in the shape of a two headed boar, that seems to be able to wander through instances freely, and without changing shape. This is a very rare feature and it's common opinion that Two Heads is either a demon - a spirit that for some reason isn't chained to karma - or a cambion, the spawn of a spirit and a demon ( more: https://www.furaffinity.net/view/44933490/ ).
In any case, he seems to be fond of other spirits' meat and won't refrain from killing and devouring someone if he feels like it. His strenght is enormous, being a boar as tall as a first floor, so the most part of people just avoid him. He's not very fast so as long as you're not wounded or incapacitated, it's pretty easy.

Sometimes Two Heads likes to talk. Those that have discussed with him (from a safe position I guess) says he's very, very smart if a bit ancient mannered, and has a good sense of humour. Still, the feeling of impending danger that surrounds him like an aura usually discourage everyone to form a bond. Two Heads himself isn't incredibly eager to be loved, it seems, as anyone stepping too near is usually killed and devoured.

The second head seems to be not-conscient, and it usually moves its mouth depending on how the principal head does. Two headed though refer to himself as "we", so who knows if they share some kind of brain communication...
