sharingan_eyes (Level 9)

@taichokage: oh yikes i was gonna make it frieza vs Ulquiorra, would you think that would be a bit more fair??

vs 
 

@taichokage: however upon reading this i will admit that Aizen will probably beat Madara, and i will applaud you for stating why so nicely seriously you changed my mind on the subject, good answers!

@taichokage: i'm not gonna lie, that's impressive and has me thinking Aizen is pretty awesome but i still think Madara will at least stand a chance, i see chakra as a form of Reiatsu, sort of  like the opposite though reiatsu is the effect of being powerful while chakra is the cause, anyway i think madara's chakra will protect him against the damaging effects of Aizen's reiatsu allowing him to get close ( of course this is speculation since we dont know what would really happen) and madara managed to completely control the Fourth Mizukage  with his sharingan, as i mentioned in an above post, sharingan users have been shown to be capable of seeing through all types of illusions including Aizen's. yes izangi is cast on the user instead of the opponent but the user can literally make his own death an illusion  however that being said i'm still not positive Madara could win, i'm simply stating it'll be a better match up than some give it credit for being 
 
 
as for Orochimaru vs mayuri i think mayuri still doesn't stand a chance 
  
yes he's faster but orochimaru has tons of moves up his sleeve, you mention quality over quanity but the quality of orochimaru's jutsu is great as well, he is a master at every move he's learned. he has been shown to be strong enough to kick a tree and knock it down unaided, he is immortal to virtually all forms of injury, he has been cut in half, poisoned, and punched by Tsunade (who has super strength) and survived, he has been paralyzed before by the third hokage and still was a dangerous opponent, and as for Mayuri's bankai, it is quite a target, while it poisons anything in the area, it can be blown up or impalled. while mayuri's super sense poison is deadly, he only beat szayel with it by having him consume nemu, orochimaru wouldn't try to do that and would also keep good distance between attacks with wind release great breaktrhough he can level entire areas with one blast. he can create the three rashamon gates that can block most blasts like kido. he can shed his skin to heal from all attacks, and actually become a giant snake composed of smaller snakes, if he is cut his blood is poisonous to whoever it gets on.

@FormerCrimsonKing: i know Aizen never controlled the hollow, it was an example of what he would need to do to be equally as impressive, the rinnegan has the same effects that it had with pain, so he CAN controll other bodies which i'm sure he will have made (the feats you ask for simply aren't shown yet since he's relatively new but are without a doubt possible) as well as controlling all six elemental jutsu styles. he has had the EMS longer than any Uchiha he has completely mastered it which means he can use all of it's abilities, inculding tsukoyomi, amateratsu and susanno without the draw back of going blind, true using izanagi will shut his eye down but after such a powerful attack it will leave Aizen drained if not defeated. as a master sharingan user he can easily tell illusions from reality (all sharingan users have been shown to do this) and will know Aizen's illusion from the start. he is just as smart because like Aizen, he controlled a powerful group (the Akatsuki) and like Aizen started a war against the established order while remaining in the shadows 

@taichokage: i just think Madara has a good chance, his Eternal Mankgekyo is the strongest jutsu creator in the world, it would most likely see through Aizen's absolute hypnosis, his sharingan also can use Tsukoyomi, Amateratsu and izanagi, which can literally make illusions real, he can become intangible which makes all of Aizen's physical attacks useless, he can go into another dimension to successfully dodge Aizens powerful blasts (kido, ceros, etc) and can even trap others in that dimension (isn't that how Aizen lost? he was trapped in hell?) and lastly he's physically strong too, able to block large swords with his bare hands (something bleach characters do all the time) and now with the Rinnegan he can inhabit six bodies allowing them all to fight for him. he's just as smart as Aizen, a great leader, and the only person in the world capable of controlling the nine tailed fox (which i'd say is equivalant to Aizen controlling Ichigo's hollow) 
 
 
 
as for Orochimaru, Mayuri does'nt stand a chance, Orochimaru has mastered thousands of jutsu compared to Mayuri's smaller number of learned kido, he's intellect is equal if not greater than Mayuri's if he IS cut by mayuri's blade, he can shed his skin to successfully be rid of the attack as well as summon thousands of snakes (or one really big snake) to attack Mayuri's bankai.  he can stretch his limbs hundreds of feet and turn his own body into a snake comprised of thousands of other snakes, making him virtually immortal, he managed to defeat both the 3rd hokage, and hold off two other sannin without using his hands as well as fight a four tailed naruto to a standstill, if that's not enough he can use his ressurection technique to bring back dead warriors to fight for him in battle

@taichokage: yeah i thought the same when making it, but i do think that Orochimaru can beat mayuri and madara has a good chance of beating Aizen

@Destinyheroknight: i didnt mean ultimate Naruto, i meant it was the ultimate battle between naruto and bleach

Itachi Uchiha vs Byakuya Kuchiki  
 
Naruto Uzumaki vs Ichigo Kurosaki  
 
Sasuke Uchiha vs Urryu Ishida  
 
Kakashi Hatake vs Kisuke Urahara 
 
Sakura Haruno vs Rukia Kuchiki 
 
Hinata Hyuga vs Orihime Inoue 
 
Ororchimaru vs Mayuri Kurotsuchi  
 
Jiraya vs Shunsui Kyoraku  
 
Six paths of pain vs Genryusai Yamamoto  
 
Madara Uchiha vs Sosuke Aizen  
 
 
who wins each match up? (and yes, the Naruto verse people can see the shinigami)

@Haofan123: kakashi managed to keep up with rock lee when he was opening the 8 gates, rock lee was moving at a speed equal to flash steps, even if Deidara is weaker than kisuke, flight isn't nessicarily everything, there are ways to over come it, plus if kisuke wants to defeat kakashi, he's gonna have to come down eventually, lastly kakashi knows over 1000 jutsu, i'm sure a great fireball is enough to negate any kido as for benehime i agree most justsu would fail against it, but kakashi has shadow clones, if they get hit, kisuke would think the match is over allowing for a surprise attack

@FormerCrimsonKing: pretty sure kakashi's sharingan can keep up with his speed, flight is no problem as kakashi once fought deidara who was in flight and kakashi has jutsu to counter kido, i'm not saying he'd win, but it wont be that easy

@taichokage: care to explain how or why?

vs 
 

who wins??
