How is gaara the weakest?Oro negs.
Gaara is the weakest of the Gokage and Oro has an asenal of jutsu he can deploy. Also Great White Snake Mode and 8 Headed Hydra Mode.

Gaara wins this,
--gaaras sand blocks pretty much everything in his arsenal, and that includes his summons such as manda, as gaara has the speed to either manouevre around it, or has the necessary sand to restrain it and overwhelm it
Gaara wins this,
--Orochimaru doesnt have much of a chance into even landing a hit on gaara, let alone land it and breach his defense, he cant evade his sand and gets crushed by sand suffocation and bombarded by sand attacks which definitely take a huge toll on him
--gaaras sand blocks pretty much everything in his arsenal, and that includes his summons such as manda, as gaara has the speed to either manouevre around it, or has the necessary sand to restrain it and overwhelm it,
--hydra isnt doing much either apart from tiring orochimaru out, its too slow to land hits on gaara and hasnt shown any offensive feats at all, it still wont have the range to properly land its blows and each snake bite can still be blocked by his defense
--several snakes are crushed, kusanagi is blocked, true form is restrained and its poison is blocked, so the majority of orochimarus arsenal is countered
Don't care about the rest of your post but I noticed you state his poison is blocked. How if you don't mind me asking?
In the sense that his sand defense will protect gaara from getting hit in the first place
Orochimaru already managed to kill his dad, so he should have have a way to get past the sand. He wins S1
Perfect Jin Gaara wins S2
OP never said anything about Gaara being perfect.
OT: Not sure about S1 but S2 Oro definitely takes this.
I dont know how someone got to the conclusion that Kusanagi gets block. Debatable in a "slash" motion. But with a thrust/piercing motion, its seeping through Gaara's defense and landing a hit.
That said, I see Orochimaru pulling the same tactic Deidara did that caught Gaara[You must be registered for see links]. Instead of clay, it would be undetectable spores. Giving a kill for Orochimaru, at the end of the day.
It's going to seep right through Gaaras ultimate defense and land a hit? Based on what? Never coming close to happening. Slashing motion get's laughably blocked every single time.
Would never happen. That only worked because Deidara was also an aerial fighter and Gaara mistakenly used the same sand he was shielding with to attack. Orochimaru being a ground based fighter will never come in contact with that same sand, when Gaara would have a desert-esque quantities at his disposal on ground level.
Base on its attack power being portrayal as Sasuke's Kusanagi (w/ Chidori channeled) and Kimmaro's bones. Basically chakra enhanced weapon, but without the chakra. And it can extend meters away? I dont see why not.
I dont think it matter's either fighting aerial or not. We seen countless of times (all Gaara's battles in aerial form), that Gaara levels himself to where his ground opponents can end up catching him. And considering the fact that only his gourd's sand speed is impressive, which every other sand from Gaara can be evaded and used as platforms, like what Joki Boi did.
Plus Orochimaru has another element of surprise, which is his able to stretch meters away. I dont see this being a problem.
Kimimaro's hardest bone and strongest piercing attack completely shattered against Gaaras ultimate defense... so I don't see where you're drawing the conclusion that the Kusangi blade will get the job done. Madaras susano'o sword has repeatedly pierced through Gaaras sand defenses, but Orochimaru will never come even remotely close to obtaining the thrusting power that susano'o posesses to pierce through. The sword failed to pierce through a V2 cloak, which has never been hyped up like Gaaras sand defenses.
Orochimaru will never get the chance to extend Kusanagi at the necessary length to even touch Gaara... that would restrict his movements, and Gaara is capable of attacking and defending simultaneously.
Part one aside, when have we ever seen Gaara fight alone...? That would only be against Deidara. In every other battle he is fighting alongside people that don't complement his long-range fighting style. Throughout the war he was fighting alongside his battilion, which restricted him, as he had to stay close in order to defend and command them (refer to his fight against the Trollkage). Against Madara, again, fighting alongside the Gokage. Taking to the skies far away from your comrads and utilizing large AoE sand attacks simply doesn't work to your teams benefit, because A) You can't strategies with them, and B) large AoE attacks that devour an entire landscape can hinder them. Point being, Gaara can't fight to his full potential if he's not on his own.
Gaara never used AoE against Joki Boi for the reasons I explained above... so that point is moot. Gaara is a long-range fighter, and should never approach Orochimaru within a few meters radius. That doesn't make sense.
Bones shattered because of its density, which end up smashing it to pieces. It still successfully drill inside. Difference here is the sword can continuously extend, the fact the density is not breaking the sword. Plus that defense is much different as its formed under extreme pressure and is built of the strongest minerals which Gaara needs to derive from the earth. Not possible in the air. Im sure your getting these defenses mixed up.
@Bold: Please be honest on which defense is superior here.
I mean shadow clones and parasite clones helps not reveal the real Orochimaru. Summonings and Sand encounters give leverage and platforms. If it so happened, a parasite clone can take over.
Dont see how that matters, yea so maybe his only real 1v1 fight was Deidara, doesn't change the fact that all of his battles fights at the level of his opponents. And I dont see it as an excuse of using "full potential" when he outright use a Tsunami wave against Deidara (You must be registered for see links). Sure I can agree that Gaara situation, wont do team attack, but I think your exaggerating that the moves he couldnt do before then, would even put down Orochimaru.
AoE moves isnt putting Oro down when the latter has Summonings to hide in, and earth style to dig out faster then Kimmi has shown when hit by one. Plus undetectable Mayfly traveling
Scenario 1: Has Gaara displayed immunity to/the ability to dispel Orochimaru'sYou must be registered for see links? Orochi could blitz the majority of the 40 meters/131 ft. distance with his speed (4.5 in the databook), use Killing Intent and paralyze Gaara for a moment while he does his thing. We are going by feats right?
Scenario 2: I really have no idea. It seems like it would come down to Shukaku Gaara vs. Eight Branches Orochi (there could arguably be summoning beasts like Manda present as well).
