I wouldn't outright dismiss that theory, Natsu, so far, is the only mage capable of eating Magic that isn't Fire (so far he has eaten Laxus' Lightning and Etherion, the latter making him go into Dragon Force, or even GS Fire), an ability no other DS have even remotely suggested they were capable of doing.
