This is one of those curiousities that I'll admit to here. It might seem that Guy is to inactive to
ever win one of these things. Yet, you'll also notice that nothing really bad ever happens to Guy.
Nothing. And he follows around Mr. Snodgers. Further, I can't even picture something bad happening
to him. He may be irritable, but he's unlikely to get beaten up under any circumstances.
In determining this figt, that plays out. The demons would hurt Guy, all things given. Guy can't be hurt by my current definition in the comic. Thus, Santa Calros must crush them while going a bit overboard on the whole "Crushing things with his Pirate Ship" bit from his own fight.
Of course, Guy doesn't have to be happy about any of this. But it's not like he's got the type of personality to fight it either.
