Anyone Know which body Hydragorgon uses in his screenshots?

[Yoen]

Hydragorgon is no longer an active member and i was just wondering which body he is using here

I can't speak directly to the screenshots that you show, however, he says on the support thread that he uses CBBE:

 

So, it is likely not too much of a stretch to assume that they were done with CBBE (and Bodyslide).
