"Mimic" is the first planned Quint-Element Monster, consisting of every Element other than Fire. It was scrapped, though, most likely because there was no Island on which it was possible that such a Monster could be bred. It might possibly come back in Dawn of Fire, though, where breeding Quint-Elements is entirely possible and canon. The entire thing about Mimic could just be a rumour, however, as I haven't been able to find a verifiable source stating that there was a planned Quint-Element. Perhaps I missed something.
