I'm a fan of the classics. Maybe I just watched the Princess Bride and Zorro to much.
I want a sword that turns me into a muscle bound, mullet-wearing, princess rescuing, big fucking cat riding, super hero. I mean, FF7 swords are cool and all, but the POWER OF FUCKING GREYSKULL! Think of what you could do with the ability to turn one of BlahBlahBlah's cats into a big purple tiger that you could ride? Coolest. Sword. Ever.
