He's a discount Gaius, and it makes me wish he felt the same way about Gaius that Nero felt about Cid, just so someone could taunt him about how he isn't nearly as good as Gaius was.
That said if he ISN'T dead by the end of the Triad storyline, that means he will almost certainly go insane with power cause thats when he'l truly turn into a Kefka expy. Which we'll see how close he is too Kefka, maybe he'll end up nothing like him...maybe he will. Nael ultimately wasn't the same as Seph despite being an expy so there is a good chance we'l get a different character just with recognizable circumstances.
