Earth Grudge Fear, alternatively called Jiongu, one of the more awesome abilities that was introduced earlier on as well. It was a bit like Pein's Path's and had the potential to be as powerful as them, but Naruto had to go and poke a hole in that didn't he? Oh well. Essentially I'd like to reinstate this concept. The overall premise being stronger then both the Uchiha and Kayuga: that Naruto's Rasenshuriken only destroyed Kazuku, not the actual threads. They regenerated and moved on. Regardless, perhaps we should discuss the potential pro's and con's of this...concept. On that note, I don't know if it really counts as a KKG and should be reinstated as something else entirely, but I think it something that would add a alternative to the Reingan and other more lime-light centric abilities from the series. Anyway, too me, it would also offer a use for Kabuto Kills, or an alternative use for Orochimaru Kills, something to discuss later.
Basically, how I think it would operate would be to provide a buff, perhaps a slight regeneration factor or increased dexterity due to the threads coxing out added movement. Whatever. The piece that would distinguish it from everything else would be the Hearts. I think the concept of cheating death a few times is a useful thought. The other possible benefit would be access to far more elements then before, which would become useful at later stages in the Game when facing multiple opponents. This opens up the pathway of discussion in which lie another few uses for either Kabuto Kills and Orochimaru Kills. Somehow you need a way to have hearts to use for both alternate elements and revival(Either or both). So you could perhaps rip out Kabuto's heart and take it as your own. As you can only kill Kabuto once, it would be one extra heart per round, providing a bit of a challenge to collect the hearts perhaps?
Thoughts, anyone?
