This fight was so insanely good, imo. Not only was it during my favorite arc, but it was the first time we saw Ichigo's bankai AND his hollow mask <3

I love this fight!

There's a lot of good fights here. Ichigo vs. Byakuya is classic, but it went through a few too many twists and turns for me, and the ending was relatively unoriginal (final slash vs. final slash). Ichigo vs. Ulquiorra was a beautiful fight in general, with a lot of my favorite moments, but the sudden power up ended up reminding me too much of DBZ, though it gets my vote for the coolest fight. Ichigo vs. Grimmjow was great, if a bit anticlimactic. Though it likely wont get any votes, Kenpachi vs. Nnoitra was a lot of fun, and the ending was exquisite. Still, my vote goes to another one that probably gets overlooked too much. This fight was less about physical strength and more about a battle of wits, something we really haven't seen much of in Bleach. The ending ranks as my absolute favorite in the series, a spectacular show of sadism on Mayuri's part that was just incredible. It's the main reason he's my favorite character.

This fight was too cool! I loved the action and suspense! And there was aromatic scene with Orihime and Ichigo (I'm ichiRuki fan but will take anything)
I have this episode on my IPad
"Please don't die, don't die Ichigo"
"You don't have to win, and you don't have to fight for me"
"just don't get hurt, I couldn't bare it!"
I can imitate her :)

Yoruichi vs. Soi Fon

Yeah I agree with @viktoriya773

That fight was so epic

I think all of them were awesome, but I liked Toshiro vs. Gin best because one, it had Shiro-chan in it, and two, I didn't have to worry about what was going to happen. But there was thing I didn't like about that fight, Momo intrupting the begginging, and trying to kill Shiro-chan.

That part wasn't even a fight that part was boring

I personally really liked the Toshi vs. Gin fight. There was soooo much tension involving that fight that, for me, it was impossible to not get sucked in. Especially when Matsumoto jumped in.
But my second favorite was Ichi vs. Grimm. I love all their fights, I can watch them over and over again. <3

I know right me too

I'm close seen Ichigo fighting Ulquiorra

It's sooooo good :D

Pretty much all of the fights were cool, though, I didn't really like the Szayelaporro one, because the Eight Espada was sneaky and a disappointing character. Plus, he was cheap. Mayuri's part of the fight was cool though.

Dude when I do see Ichigo vs Aizen I'm going to change my pick

i love anything with toshiroin <3
