Higonyūdō

Hikonyūtō (比鉅入道) is one of the four guardians that guard the entrance to the Seireitei. He is the guardian of the Red Hollow Gate (Southern Gate). Aizen hypnotized him and the two other guardians so he could use them to give trouble to Ichigo and his friends. But he was stopped by Jidanbō Ikkanzaka and Kūkaku Shiba. He appeared only in the manga.
