User blog comment:Sky-Dragoon-Twilight/Will we see Gajeel use Dragon Force soon?/@comment-24403746-20150429201007

I wouldn't say that Natsu has learned Dragon Force nor can use it for his own like Wendy, Sting and Rogue have (and Laxus if his power up/dragon force also counts) since Natsu's only activated when sh** started to hit the fan and nakamas got hurt.

However I fully agree with you I've been wanting to see Gajeel go into DF for a while now. So I hope when he does it'll be on a lvl like Natsu and Wendy did on their first times and not just some oneshot attack right when he achieves it. :/
