Well, there is a new Dragon that is available as a drop from a certain Nefarious Tower...perhaps the Corrupted Dragon is the Dragon half of the combo? As for the "Golden" part, maybe the Golden Stingtail? I'm currently leveling up my Corrupted Dragon, so once it's morph-able I'll be looking for a partner with a Stingtail (I don't have one) to try out the theory! Celestial Dragon is also possible as the Dragon half. From what I remember about the bugged Dragon it had more of the Celestial look to it. The Corrupted Dragon's face is a little skinnier, and I think the mane is a bit less fluffy.
