Me one sided? No but stalling time can def be done, becuz Gamabunta held off Kyuubi so y can't him and 3 other large toads hold off 3rd Raikage, or heck J-man may even summon an army of toads. Once in SM he can spam really powerful jutsu while ma and pa do the genjutsu.
Are we talking about the same gamabunta that got one shotted along with gameken and gamahiro by deva path's shinra tensei? Get real dawg, gamabunta and his fellow boss summons were taken out by one attack from deva path, and an incomplete kyubi was tossing deva path around and even resisted shinra tensei, the same shinra tensei that broke all of bunta's bones in one shot, and you actually have the gull to say that bunta can hold off the full kyubi? What nonsense!
And bunta was not the one that sheld down the kyubi for minato to seal, get your facts straight, Kushina was holding down the kyubi with her chakra chains while Minato prepared the sealing, Kushina set up a barrier so that no one would interfere with the sealing and then used chakra xhains to hold down the kyubi, bunta wasn't even there.
The only time Minato used Bunta was when Minato used the food cart destroyer technique to destract the kyubi and then he used ST jutsu to transport the kyubi's bijuu dama and then the kyubi to a new location, Bunta never "held off" the kyubi, you must have gone senile.
And you're crazy if you think Jiraiya's sage mode is on par with the raikage's raiton armour, that's if you're talking about the same sage mode jiraiya whose punch was efortessly stopped by animal path with one hand without even looking at him, you think human could stop a punch from theraikage? The same sage jiraiya that had his arm ripped of by asura path and then had his throat crushed by asura path, the same asura that was one shotted by choji's dad, really, you think sage mode Jiraiya's strength and durability can compare to the man who has never been injured accept by his own technique, tanked a bijuu dama and Futton Rasenshuriken? This guy who's body was pierced by even those chakra disruption rods through the shoulder by a half dead animal path, get real, sage mode jiraiya's speed,strength, and durability are no whwere near that of the raikage, fanboyism is clouding your judgement.
And gamabunta will get one shotted by hell stab, in fact that won't even need to be neccessary, the raikage can just go straight for Jiraiya and ignore gambunta, Deva, who is slower then the raikage avoided all three boss summons including bunta to get to naruto when he was trying to summon back his shadow clone, and that was before deva had his powers back, if deva can just avoid three summons and reach his target with pure taijutsu, then what do you think the raikage can do? Bunta won't make a difference here,raikage can easily go around him or one shot him with hell stab or super taijutsu.
Swamp of the under world is useless, its an earth technique, he can't sink the raikage, who can just funnel raiton chakra into the ground and stop it, raiton trumps earth, just look at how sasuke diffused deidara's bombs. And no ninjutus or tai can hurt him.
Frog song? Please! What on earth mader you think the third or his son can be affected by genjutsu? Genjutsu affects the mind, the mind is part of the nervous system the functions through neural synapses or impulses. That is why it is useless against someone with the raiton armour, the raiton armour amplifies speed and reflexes to the maximum by altering the neural impulses with insane raiton chakra frequencies, in other words, the raikage's nervous system is constantly stimulated by raiton frequencies that alter and disrupt neural impulses, a genjutsu will automatically be dispelled even before it takes effect, frog song won't work.
Sasuke used genjutsu against everyone of his opponents in shipuuden except for the fourth raikage, why do you think that was the case? He used it against deidara, Bee, C, and even danzo, and Itachi, who had sharingans but didn't use it against the raikage? Why, because he knew it wouldn't work! The raikage even said. So himself right after sasuke captured C in tsukiyomi, he said that a mere sharingan wouldn't work against the raikage while staring directly into sasuke's eyes, after his body guard was defeated by a genjutsu.
Also sasuke is a raiton user himself with the perception of the sharingan, he obviously knew this fact well too, that's why he was relying on. Ms ninjutsu and not genjutsu against A. All yaw Jiraiya fanboys raving about frog song aint got substance.
Jiraiya has nothing to take out this guy, whereas the raikage can take him out with four finger or one finger hell stab or just pull an asura path and rip his arm out or crush his throat, heck he can use black lightning or even use the sealing pot to seal him away.
And yaw crazy if you think Jiraiya can figure out the trick that naruto pulled. Naruto had plot no jutsu to help him out. He had bee tell him about the similarities between rasengan and bijuu dama when they were training. He had dodai and a whole iwa army squad buy him time to contact the eight tails and he had dodai to even give him the idea to contact the eight tails by telling him when the raikage got his scar and about his status as the strongest shield wielding the strongest sword. He also had the eight tails tell him that he used bijuu dama, which, combined with Bee's information about rasengan and bijuu dama similarities gave him the idea. How yaw fnboys can explain Jiraiya just randomly figuring out the raikage's only weakness without all this infois a mystery.
Fooloshness too when you believe that plan would even work against the raikage, Naruto's plan only worked because Kabuto was the one in control of the raikage's body, that plan would have never worked had the raikage been in control of himself, Injuring himself was his greatest shame and he was so paranoid about it that he didn't even tell his son about him, the guy was too paranoid to even allow someone near his arm, especially someone using a spiraling sphere, which is so similar to bijuu dama, he would see it coming and react to it, Kabuto just didn't know enough about the raikage's history to react to it. Besides, only the one finger hell stab can pierce his body, if he uses four finger, then it wouldn't kill him and he would still carry on fighting.
Third raikage will win low or no difficulty.
