Jiraiya beats Pain by himself. Adding Orochimaru is overkill. Yomi Numa will drown half of the Pains' in an open field, Toad Oil Fire roasts Deva alive, as it reaches 1000's upon 10,000's of centigrades of pressure.
Snake Barrage, hyped to halt almost all attacks should stop Chou Shinra Tensei in it's tracks as it's best feat is crushing a village diameter of buildings, with unknown durability. Pain dipshits use that feat to overhype thier little bitch, and put him above Itachi, at the same time they'll say the Totsuka Blade doesn't have feats. If there is 1 thing that annoys me it's hypocrisy.
Rashomon stopped Biju-Dama, Garbage ST a magnetic force isn't overpowering it. To say otherwise, is just rubbish. A concentrated explosive densely packed blast, is far more potent than a slutty gravitational force.
That is why the greatest offensive attack in Narutoverse, is the Juubi's Flash TBB.
Frog Song ends it, when they hear the sound, they'll instantly be trapped and, since he has knowledge on the secret of Pain, he'll switch on SM Sensing after defeating them, or he can ask the Frogs to look from the sides he can't see, essentially giving him a 360° field of vision that makes Ashura's surprise attack from his blindside useless.
He's fast enough to blitz Chikushoudou, before he can physically react, and even though she's the slowest, it is still a great accomplishment as it means there is a high chance for him, to physically outmaneuver the superior Paths, and if we add in Orochimaru who has 4.5 in speed and, reacted to Kyuubi's Tailed Beast Ball, and outmaneuvered it multiple times and actually overwhelmed it in CQC, the chances are that Pain'd be going down without successfully initiating thier attacks, since they can't take the barrage of these many combo attacks, and still be freshly equipped enough to face them in Close Quarters Combat.
