User blog comment:Bato of the Heavy Iron Rock Hammer/God Serena theories/@comment-85.237.234.133-20150729095221

Well I'm not fond of your theory because in the last chapter of FT Zero there was a timetable in which Yuri was told to be dead. Anyways, if he turns out to be Yuri, I won't be surprised either, but I don't feel like having 2 of 4 Gods of Ishgar being original FT members.

As for other theory, I can see God Serena being in some relationship with Gildarts, they kinda look alike and apparently, both are god damn powerful.
