I have a full strategy written up for you to use but try this first. Grand Summon Anima and use his overdrive. Then summon Bahamut and use his overdrive and he should die. Thats what I did.

Ohh yeah Seymore Flux. I thought it was Seymore Omnis. Too many Seymore fights in this game. I also had a lot of trouble with Seymore Flux. I kept using Yuna and Lulu's Waterga and I beat him eventually.

he was kinda hard...except for his last from...i killed him in one shot with anima's overdrive(u can do it now )and he said that his loyal anima wont hurt him....heh...pitiful creature

Here is a link if you still need help, even after DL, and HS advice. Not saying it wasn't good or anything...

Well maybe you shoulda just checked out the FAQ, its a boss FAQ and would've told you this...

Seymour Flux, Mortiorchis
HP: 70000, 4000
Difficulty: Hard
Location: Mt.Gagazet

My god, this is the hardest boss so far, no contest between other bosses. Get Tidus, Wakka, and Auron out. Have Tidus cast Hastega one everyone and the others attack. Anytime you see the words “Lance of Atrophy” on the top, immediately use a Holy Water on the person who suffered from that attack, because Zombie was caused on that person, and Seymour will ALWAYS use Full
Life on that person after Lance of Atrophy, and since Zombie condition is damaged by curatives, Full Life is an instant kill. If you do use a Holy Water/Esuna/Remedy, Seymour will still use Full Life, but it’ll just miss.
Stupid idiot. Anyways, just keep attacking Seymour and sometimes, get Lulu out to damage the Mortiorchis so it’ll absorb some HP from Seymour. When Seymour uses Dispel on all of your characters, heal everyone fully and put
your best HP characters out, because he’ll use an attack called Cross Cleave, which does a lot of damage to each character. Heal everyone, and have Tidus cast Hastega. Seymour will repeat this step until his HP is
somewhere around 20000. The Mortiorchis will then start charging up and, after a while, it’ll cast Total Annihilation. This spell is sure to kill
probably all your characters (it does around 4000 to each!!) so have Auron out (he probably has the most HP) and immediately heal up and revive the others. From here on, try to kill him as quickly as possible; otherwise Total Annihilation will be cast again. I heard from PlayOnline that you can kill the Mortiorchis to slow down the Total Annihilation charge-up, but it didn’t help much, since the Mortiochis can’t actually die. Just stay on your toes and make sure to be healed up in this battle. Seymour fit in two Total Annihilations at me, but I was able to survive (don’t try to have him do the same thing on you, though).

There ya go, hopefully this'll help ya out, and shut ya up.

well i used a totally diff strategy and beat him...i used hasteaga and protect on everyone..this usally gave me 3 attacks per wakka and tidus and 4 for yuna..i diidnt bio seymor i forgot but it still worked... i slienced him and kepty it that way with wakka and tidus... then he used cross cleave which i had protect so it didint hurt that much..when i got him to 20000 he was opowering up..strategiweas told me to put aeons out at first..but i held them untill he was about to unleash total annihaltion..i busted out bamhut and he didi 9999 to both...then valefor did 9999 then grand summon shiva who didi 9999...he was left with likie 2 hp and his dumb mortichrus stole 2000 hp from him and he was dead..wut a dumb partner to have...thanks for ur input guys i needed it
