User blog comment:Bato of the Heavy Iron Rock Hammer/Erza's Father's fighting ability?/@comment-31119762-20170214172844/@comment-24102956-20170215095223

Well, Acnologia doesn't care who he kills either human or Dragon if they get in his way. In his eyes, they're all insignificant insects to be crushed.

And of course, he is after the 7 Dragon Slayers and kill them as his goal is to eradicate any trace of the Dragons' legacy through God Serena as an example. I'm just surprised he didn't smell Irene as a Dragon despite both of them were capable in human forms in their battle.

Erza's Father might have been competent enough to survive the rampage. It'd be nice if he died.
