Well,ya know that Gajeel and Natsu have got Duo Dragon Modes. I upendo both of them,although Gajeel's one is a bit scary at the first sight. I thought like "What the hell is this?" and I was scared of my beloved Iron Dragon Slayer. Yeah I am a Fangirl of Gajeel-and I think I am the only one who loves Gajeel. I give wewe some flashbacks what happened as they got the Duo Dragon Modes.
-Natsus Lightning moto Dragon Mode-
Natsu got his Mode in the Grimoire Heart/Tenrou Island-Arc. Laxus appeared as Wendy,Lucy and Natsu fought Hades. That Mode is so awesome! Well,he used that three times so far.
-Gajeel's Iron Shadow Dragon Mode-
I was really scared of that Mode. Really,I thought he goes back to the dark side! Well,he got that Mode from Rogues shadows. "What salamander can do,I can it too",he alisema and swallowed the shadows! I was really scared of that mode,but it was awesome how Gajeel defeat rogue with it. Stupid that he uses just one time so far.
Natsu with Lightning Fire Mode.
