Here's how I could see Great Red's power working with the ideas we have so far. Issei's Balance Breaker is him essentially equipping Ddraig's skin (the scalemail) over his own in a sense.

So perhaps Great Red's power would add onto that, essentially creating pieces of Great Red's "skin" over his scalemails.

In fact... what if AxA happens to be a mastery of Issei's dragonification? He can turn into a Dragon by the EX future, and that seems to be his strongest ability as of the EX novel, so AxA could be him turning into a Dragon.
