New research suggests all formes are possible in Hackmons
Specifically, formes that normally require a specific condition,
such as Darmanitan-Z and Arceus-Fire, are now available in Hackmons.

The previous confusion stemmed from that Arceus-Fire is actually
Normal-type, and the Arceus forme is handled separately from
Multitype and plates, which is what actually gives it the Fire
typing.
