personality
unlike his Counterpart nega Naruto is rude heartless and evil that takes no responsibility of forcing Naruto to hurt innocent people when he was first created when Orochimaru force kabuto to use the forbidden jutsu confusing on him nega Naruto could be very similar to Nega Beast Boy Nega Starfire and Nega Cyborg the fact that they are evil clones there original self's when Raven father force her to destroy the world but thanks to her friends help her restored it back. however he forced Naruto to hurt Sakura and took a joy of making the boy hurt her however he could be complete a lot similar to Sonic.Exe and Mal from Total Drama the fact that both of them impersonate sonic and Naruto and mike he's evil and crazy and do everything in his power to get what he wants while trying to take over his body if Naruto lost the battle and lost his body to you evil clone but however after successfully defeating nega Naruto his plans on taking over Naruto body became unsuccessful.
