Reason: Seems like the same thing, a combination of 2 or more characters. There's also chimera_(creature) but that seems to apply to more non-human things. And since the only results for chimera -fusion are non-human, they should probably be tagged chimera_(creature) anyways.
Slightly related, is there a tag for when someone/something has a some sort of a head for a hand, sort of like post #651787 or post #478419?
