Yeah, the director mentioned his name in the making of footage, he basically said that Doras was what he imagined an evil Kamen Rider to look like
>>Also, what's the deal with Doras being alive in the end? Setup for a sequel?
Spoiler
damit now ive gotta go check to see what's what
But on the terms of a squeal, Didnt Kamen Rider J follow this? since Zo appeared in the cross over Kamen Rider World with J, was he not a bad guy in that, damit something else i need to look into, alflip
Doras was kind of a butt ugly rider, but not the ugliest rider i have seen
something else I just remembered, that boys mum was mean just dumping him at the film set and leaving him there alone
