Re: Why is Tia Harribel 3 and Ulquiorra 4?
IMO, Aizen did know about Ulquiorra SE, I mean look at him, you cant keep a secret from Aizen, the dude knows Ulq better than he think he does.
As for Harribel, come on!! You know what, anytime a Female character is stronger than a Male, people just bash on the female to make her seem weak. I cant be the the only person that sees this. In Naruto, people bash on Tsunade calling her weak, god know if she were a male then she would be treated better.
Harribel held off 3 opponents. While they look battered up she barley looked like she even had a scratch on her. And imo Hitsuguya did not "beat" Harribel. His only option was to trap her. Not to mention she was already a Vasto Lorde before Aizen recruited her, So trust me she has the skills and power.
Ulquiorra is strong but his main thing that makes him a challenge for the top 3 is his speed. And thats about it, his speed.
