after all it was ikkaku who trained renji
heh heh heh...................

Baldy has more motivation ^ ^
And he doesn't have to lug around a huge weapon in bankai state

even tho ikkaku trainned him renji is vice captain who doesnt hide his bankai. Renji will give his all in the fight

ohhhhhh u wish once renji himself chose ikkaku to be the squad 5 captain............but to fight and die as zaraki's comrade is his dream..............ikkaku's power in bankai state rise slowly.............but if it is at full power renji is toast,,,,,,,,,,,,,,,
heh heh heh.............

Renji...I guess

I'm stronger in believing that Renji-kun would win.

ikkaku is the best he can defeat renji in no time

My man Renji does have heart... but I forgot about Ikkaku training and helping to strengthen Renji. Hmmm. He'll know a lot about Renji, but not all, maybe, perhaps Renji will have surpassed? I just soo dislike Ikkaku coz he scares meh, lol, that I root for Renji anyway, even if it might be tough to tough to call. :/

Ohhh now that's a hard choose to pick damn good question though

ikkaku is slow in powering up but if he's at full power in his bankai state his distructive power is lot higher than renji..............u know even renji was begging ikkaku to be the captain.............but is passion towards zaraki that he wants to fight and die as zaraki's squad member made him a 3rd seat..............and ikkaku is too scared to show the bankai to zaraki and other squad members bcz he knew if that happens his captain will challenge him to a fight to death...................a strange guy he is,,,,,,.............heh heh heh

Ikkaku. It is simple... Ikkaku is a lot more focused than Renji and has more battle experience. Plus, he grew up constantly fighting and is an expert. Renji is awesome, but he still has a lot more to learn in comparison to Ikkaku.

yep i totally agree to u bro....................

Ikkaku because his zanpakuto's abilities are one of my favourites! His bankai is awesome!
