Acnologia is the Dragon King. And from Future Rogue's future, Acnologia dominated the world, so i'm pretty sure God Serena at his best can't even put up a fight against Acnologia. He even took on the full force of Igneel's breath attack unfazed, if God Serena somehow manages to even put a wound on Acnologia something Igneel used his life to achieve that, i'm gonna call it a bigger BS than Acnologia owning God Serena.
