For all the comments above, I agree. The reason why God Serena was my favorite Spriggan (more than Brandish surprisingly) was because of his somewhat eccentric personality. Completely defied his status as the "Strongest Mage in Ishgar". Anyways, his introduction as a Dragon Slayer was..... a bit much imo. I think he could've been more of a powerful individual if he didn't have such magic. Having one of them is already tiresome to master. EIGHT of them was just.... plain overboard and signaled a death flag (which, as you all know, eventually happened) from the start because of Acnologia's desire to "eliminate all traces of Dragons".

Again, like the case with Mard Geer, much potential was wasted with this character, which could've gone in a better direction if Hiro had not been lazy with this arc as with the Tartarus Arc and "that which shall not be named" Arc. This is my honest opinion.
