Dreadwing
This is the Powermaster Gestalt from series 5. The picture was taken from the Japanese giftset. The image had to be edited a bit since the Japanese version has red plastic where the American version has light blue. There is a Japanese Tech of the gestalt form, but I didn't quite like it and made up my own bio. Interestingly, the giftset name is Darkwings.
