>>22658726>Mecha Mega Hydreigon>arbitraryIt has been outright stated that the original draft of Hydreigon had the Steel/Dragon type combination, and it still has tank tread-like markings left over from the original design. Hydreigon also draws heavy inspiration from King Ghidorah, a giant three-headed wyvern who was resurrected as a cyborg in order to protect the world from the beast that felled it. Steel/Dragon Mega Hydreigon is a far more logical progression than a number of the Mega type changes we've seen thus far.
I have faith in the Game Futurians.
