There's sooooo many Jenova's to fight but.....I'm gonna assume it comes down to that ball of tentacled flesh that calls itself SYNTHESIS.

I normally blast the thing with KOTR (its exactly how I dispatch diamond weapon, if those things even think about giving me a countdown then.....bam! Its Authurian Time!)

I think last time I tried to defeat Jenova a different way.

Methinks however I shall stick to kicking its ass in one turn.
