"Deino, Zweilous, Hydreigon
At first, these incorparted an army tank motif, and the marks that look like a conveyor belt on the upper part of Zweilous’s legs are the remnants of that.
Initially, they didn’t work as designs and were basically ‘put to sleep’, however, a three-stage powerful Dragon-type family was ordered and they were resurrected.
In the second half of development, there was discussion about making them a colour that was not used much in the Pokedex, and from all the candidates, a strong looking purple was chosen.
The motif for the line are Yamata no Orochi (mythical Japanese serpent with 8 heads), but actually giving it so many heads made it a little displeasing so they gave Hydreigon one ‘real’ head, and made its arms and wings look like it had many heads when in silhouette.
The ‘heads’ of Hydreigon’s are really hands and do not hold even the slightest bit of individual brain power. "

Hydreigon is also much more like Orochi in personality (just without the maiden-eating and getting drunk part).
>>17482391It's really not. They didn't mention King Ghidorah at all, just Orochi. At one point they might have gone "hey, its three heads make it look like King Ghidorah," but the decision to reduce its heads to three was stated to have been born out of simplifying the design.
