@taichokage: You mean Juubidara/Juudara? Yes. And if you thought Juubito was strong, Juudara is going to be so strong. Basically "base" Madara is way past "base" (by base I mean without the Juubi's power) Obito. Besides Kamui, Madara is > than him in every single way. Now imagine Madara, who imo is close to Sensui is strength who I explained would wreak massive havoc on Bleach (either that or just bullying Ginjo for being a complete ripoff of him which is something that most people would agree with me on, yeah I'm not really a Ginjo fan plus I think he is lucky if he can beat Grimmjow in a fight), with the Juubi's power. AND he's an Edo. BUT, Bleach is getting powered up too. Not Juubi level, but still. Take that same logic I had in regards to Madara and Obito. Now take that logic and apply it to Ichigo and Renji/Rukia. Throughout the series (since Ichigo fought Byakuya and Kenpachi) Ichigo has been immensely stronger than both Renji and Rukia. Now look at those two now. I could only imagine what Ichigo is going to be like. BUT, another thing is whether Ichigo is going to be as strong or stronger than in his Dangai state or even his H2 state (although I think he is way stronger than his H2 form). Because I will always believe Aizen > Juha Bach (mainly due to preference and plus Aizen grew on me a lot and the fact that he is a major troll, which Juha Bach himself can agree with me, and he is just a likable villain). Also Rukia and As Nodt should continue fighting because someone who beat Byakuya getting beat so easily by Rukia, regardless of Zero Division training IF she surpassed Byakuya it shouldn't be large because come on, it's Byakuya we are talking about, is a little bull imo. If she does win it should be like against Aaroniero where she barely managed to pull it off because As Nodt is one of the stronger SR. Also how much stronger are the SR compared to the Espada because I personally think R2 Ulquiorra can take someone of Mask's caliber with high-extreme difficulty. So we will have to wait and see. Man but both mangas are kicking ass lately! Sorry for the long post lol but I have always been excited for Bleach and Naruto but man they are taking things to a whole new level of excitement, action, and overall awesome storytelling.
I like Tsuna more and with ultimate dying will mode he should be able to react to and counter any sort of physical cqc attack Aizen throws at him. With the Oath Flame he'd be able to manipulate the terrain around them and could possible be able to create a pseudo black hole and suck aizen into one.
So I'm going with vongola decimo on this one
Actually, I would give this one to Tsuna. Aizen is bound to underestimate Tsuna like he did with Ichigo, which would give Tsuna enough time to either use a Zero Point Breakthrough, or charge up an X-Burner. Though that is if Aizen is in character, if he is bloodlusted he might have a chance to defeat Tsuna.
@taichokage: Aizen really likes to underestimate enemies, even if he doesn't know what they can do. He had never seen Shinji's shikai, but he just stood there and let him spread the Inverted World gas. He also allowed Soi Fon to hit him with her shikai twice, even though he had already seen it. Tsuna doesn't have any spiritual energy, so Aizen can't judge him like he tried to do with Dangai Ichigo, so he is bound to underestimate him like he did with Shinji. That would give Tsuna enough time to charge up an X Burner or a Zero Point Breakthrough.
Tsuna would smash Aizen into the ground. He isn't faster than Aizen, he's massively faster. He was able to react to Jaegar and Bermuda warping around him, and he wasn't even in his strongest form. The only chance Aizen stands is to catch him using Kido.
