Double Helix
Yuffie you little coniving thief, first you hide in thick woods, waiting to spring on the heros, then you place a save point net to your helpless body and if they were to use said SP you'd take their money.
when entering wutai, you make it so the party cant leave untell they play your pathetic, irotating form of hide and seek, you steal other peoples hard earned materia and then in AC you ask whos been touching you (stolen) materia, you little creeper.
in DC you never help vincent during combat, you help him escape from the crimson and we all thank you for that but a little more help would have been nice ....
in KH you use a super star and that would have been very useful in FFVII but no you had to save it to use in the damn colisium. so yuffie..... your a *@&#$
