Help FFXIII: (spoilers) Fifth ark boss

[LadyGagaWillEatU]

I need help with the first boss you fight at the 5ifith ark.
My people are lightning,vanille,and fang, because thease 3 helped ALOT with the last boss.
i try to beat the boss person but he always does his combo move on lightning and i die instantly even if i have full health. Its not my fault if she dont have enough health.
I think this game should be scaled to your level.
Anyway give me a good tactic to beat him!

Edit: ignore the tittle, pretend it says 5ifth ark

Yes it is, you clearly need to train her more to GIVE her more health, or equip accessories that will either boost her defense or her HP

Other than that I cant think for fuck what boss you're on about so...

I concur with the above can you specify wich "boss" you are talking about? Do you mean Cid?
Build up your chrystarium more
Make use of your sentinal thats whta they are there for,the sentinal will take the brunt of his attacts while you heal...
If you can launch him toggle him with restless assult in the air for as long as possible.....I beat him rather easily
