An Alien who, unlike most aliens who wants to conquer earth, wants to find "heart of all earthlings".
By that, he wants to be more tactical about his approach, and not resort to violence, as he hates it.
He wants to ask any earthling he meets if they could give them the earth in return for a new star.
The planet Mefilas comes from, Planet Mefilas, has its star dying, so he seeks for a new one that way.
He detests violence, and won't resort to it unless it's necessary.
He's a skilled fighter.
