[Theory] Why Franmalth absorved Natsu's Fire Lightning Dragon Roar

[Dãrth1]

Well, the title explains, what I think is, when he absorves a soul, like when he did with Hades, he get the memory of it, and then he can absorb every magic that was used on that soul, like with his Roar, because he used it earlier on Chapter 246, page 09, so he could absorb it, what you guys think?

yeah ...........it seems like franmalth can not only absorb soul's magic power but also the attack from the opponent
