HELP!!!SEYMOUR FLUX IS IMPOSSIBLE TO BEAT!!!!

My advice is have Auron beat him repeatedly around the head with Rikku.

One word: Overdrives.

;; he is easy as hell ~_~ all u need is tidus auron yuna for this battle. if u cast hastega on ur party befor seymour do full-life after zombie attack u will get ur turn so use remedy, and holy water to get it off before he use it. and whenever he casts reflect on him dispell with yuna so he will damage him self when he casts some magic. just hit with auron and tidus like mad. when he dispell all of ur party members cast hastega again.

Sorri.Everytime Im stuck on a boss I yell for help.Ya Hes super easy if all ure aeons r in overdrive.Thn use Auron to hit him some more.I did the same thing with the Sactuary keeper and Yunalesca.Yunalesca was 1000 times easier than even the first Seymour fight.It took me forever to do that!Now Im training and doing sidequest and the omega riuns to train for Sin.

I found the overdrive tactic thing harder for Yunalesca since she has three separate forms and a total of 132,000 HP.

then again Yunalesca is easier than Seymour flux because she cause the zombie status, if you leave it for her final form when she does that mega death attack the party members with zombie wont be affected.
