(This idea was thought up when I heard Zaraki Kenpachi didn't hear know his blades name yet,Now we all know how fucking badass he is so I'm gonna give him the most powerful Shikai in existence,You'll see how awesome it is. P.s this is my version of the Ichigo Vs Kenpachi fight.)
Ichigo breathed heavily as he looked at the scared body of his fearsome opponent, Who had his blade out and ready after he almost hit him with Zangatsu.
Kenpachi grinned demoniacally at his opponent then he said"Well kid you're pretty good but I still haven't gone all the way yet."
Ichigo glared at him and snapped out"What the hell are you talking about?"
Kenpachi grinned at him again as he replied "Well brat you may have already unlocked your Shikai but I have yet to show you mine."
At that Ichigo started as Kenpachi lifted his blade and intoned"Mighty king of all battles ,Lord of might,Master of all fighting arts :Awaken Chuck Norris!"
At that a bright light started to come from his blade, Slowly it turned into a pair of metal,Steel spiked boots with three massive prongs come from the heel and five from the toes. Then a brown cow boy hat floated down from a stray beam of light,Kenpachi grabbed it and put it on top of his head at a jaunty angle.
Ichigo gulped as Kenpachi said while moving into a fighting stance where he could kick him better"So you ready to get your ass handed to you kid?"
(What proceeded was a gory and brutal ass kicking for Ichigo after it was over he was broken into pieces from the horrific beat down he was given by Kenpachi who would go on to obtain his Bankai, Teichou Taka.)
(And that is why Kenpachi will never get his Shikai because it will be overpowered to the point of no competition since he is a god of badasses therefore he will get an equally awesome Shikai and Bankai.)
