Re: how is it that kakashi can use all elements
The Rasengan is a technique that anyone can use. It's not an elemental technique, it's simply a chakra based technique. and i don't even think he copied it, i think it was taught to him. i could be wrong on that point, but i'm pretty sure he didn't copy it and i know for sure that it's not an elemental tech--it's not earth, wind, lightning, water, or fire. it's just spinning chakra (well, there's more movement than a simple spin, but that's basically it). So yeah, anyone can learn Rasengan cuz it's simply a chakra-based tech, not an elemental chakra-based tech
