Okay, Wendy has become awesome. So if high quality elements activate Dragon force, I wonder if eating gold or platinum activates Dragon force for Gajeel, but it probably needs to be infused with magic like the gold fire or Face's air.
Aggravate, Anger, and Piss off
Damn Wendy just became awesome, I hope we see Gajeel go Dragon Force
Side story for you.
I Love You!
