O.0, I really doubt Barragan can fight him Barragan is a vasto lord (just old and thinks his ability is invincible) Bikou is an Arrancar even without releasing his sword/sword he's supposed to be much stronger.
Nah, the novels made barragan seem much more powerful, considering he was supposed to rival Ikomikidomoe, the same guy who beat Yamamoto when he was younger.
