Because they are two different scenarios genius. The first Hirudora has a bigger DC, but the goal was completely different. Gai was never trying to kill Kisame in the first place, but to counter Kisame's gigantic building size GSB. Everything else was collateral damage. It's similar to deva path tanking k6 naruto's TBB, but getting killed by a rasengan. The reason being that he was at the edge of the blast radius, so the energy output exponentially decays the further you go from the epicentre.(same with Kisame and Hirudora). The fact that Kisame was STILL paralysed speaks volumes. Of course I know the DC of the first Hirudora is greater, but the point I'm making is that if it was done on land, the Hirudora would be MORE powerful.
The reason why the second Hirudora is more applicable, is because the situation is likely to be the same in this fight. You are suggesting that she'll summon Katsuyu as meatshield, similar to Susanoo being a defence( Not that she'll ever being able to summn it..) In the madara fight, Gai's goal to break open Madara's Susanoo, and damage him as much as possible. The fact is, an EXHAUSTED Gai, destroyed a v3 Susanoo, and damaged Madara as well. So unless,Katsuyu/Tsunade have a much higher durability than a v3 Susanoo,they get destroyed and turned to maroon paste instantly. Quite simple. They'd probably have to have durability on par with a v4 Susanoo to take it(the same Susanoo that blocking the impact of TBBs getting slammed into it.) There's nothing that even begins to imply that Katsuyu/Tsunade are that durable. Lol
But it's not the strongest one that he's capable of. Again....
-He wasn't trying to kill Kisame.
-The attack was done UNDERWATER, where it's harder to gather air pressure, and he had to go through a massive GSB to boot.
Of course, even the Hirdora an exhausted Gai used is enough to win the fight against Tsunade, so this isn't that important....
All irrelevant, as my point is that a fresh Gai's HIrudora on land would have greater DC than what we saw on either of the 2 occasions.
Kisame used an attack to try and counter it, but didn't get the full impact of the blast because of it. v3 Susanoo>Katsuyu by feats durability wise. No evidence to suggest other wise.
No, she dies a horrific death. Even Gai's 7th gate punches/attacks would kill her as he can output damage faster than she can heal and kill her before she can regenerate. Hirudora is possibly not even needed.
It pretty much murdered a 30% Kisame clone. More than sufficient to take out Tsunade instantly.
Did you read my post? No where did I imply that Hirudora is as powerful as those techniques, but just like those other techniques that were listed(PS slash, bijuudama etc), it outputs a greater damage PER UNIT AREA than chou shinra tensei(as some fodders survived it). That is what is important. Just like fodders survived the Juubi tenpechii with a cloak. Hell Madara's v3 tanked it, yet was brutally destroyed by Hirudora. Is Hirudora above Tenpechii power wise overall? No, but it produces more damage per unit area. There's no evidence that Tsunade can withstand such an attack.
Ay tanked it without any damage, and WITHOUT healing. Tsunade had her healing technique on the entire time, but still had minor difference. You need to learn the difference between durability and healing. Tanking attacks head on like the 3rd Raikage is durability. Healing from something is not. Tsunade's body isn't even close to Ay's durability, especially with his ration armour. Unless you're implying that a chidori won't penetrate Tsunade's skin properly and give her a minor wound only............ Tsunade is no where near Ay's durability.
Irrelevant, Gai pushed back Juubi jin Madara.(more than what Tsunade would have done), hence his speed is eons above hers. He blitzes, and pounds her body with skull bashing 7th gate punches at a faster rate than she can heal, and she's not hitting him with her speed. Even if she does heal, Gai is smart enough to resort to using a kunai in gated mode like Lee did, to decapitate her. Gai wins low diff
