Before I do anything else, I want to say that I love your new avatar.  Setsuna F. Seiea, right?  Gundam 00?<br/><br/>That said, Karin's current plan is to use "Bolder" as a wrecking ball and crush her foes.  It's not rolling around yet, but it likely will soon.  If anyone needs help, she can use her 'Tarantula' to provide sneaky tactics by attaching chakra threads to other people and pulling them into attacks, ripping weapons out of hands, pulling allies out of harm's way and similar things like that.
