Biography:
12th division captain Kurotshuchi Majuri. One of the wierdest captains in Gotei 13 since his psycholigical and physical appearances are pretty odd. We meet him for the first time on Captains Special Meeting. He proves to be cruel and not very well behaved back then since he’s still in conflicts with other captains (especially with Kenpachi). Majuri is nowadays the President of the research institute of technology (he took this job after Urahara btw...). He’s tall, suspiciously looking guy with chains in his ears (sick!) and posionous, green blood (propably it is a part of his experiments).

Majuri took Urahara’s place after Kisuke was delayed from Soul Society because of his researches.From the very beginning he proves to be cruel and spoiled. He is able to took shinigamis life just to increase valuability of his researches. Propably he created his own body during one of the experiments, since it is very hard to destroy his soul form. Every time when his actual body is destroyed he turns into liquid and go back to his laboratory to create another body. Although it takes some time to restore his powers and make his body look like before. Majuri’s history is unclear since we don’t know much about him. One is certain, he was one of the shinigamis who gave orders to vanish Quincy race 200 years before Bleach plot starts. Since that día he was researching quincy’s body to find clues about their powers. He is also responsible for Ishida’s grandfather death.

Kurotshuchi meets Ishida on his way and instantly wanted to research young quincy’s body. Fortunatelly Uryuu was powerfull enough to defeat Majuri (even in his Ban Kai state, -proves that quincy race had tremendous power). Battle was long and took a lot of damage to both sides (Ishida was pushed to use stg like BanKai for quincy’s, he reached his limits of power and easily defeated Majuri). During the fight Kuritshichi even deadly hurted his own vice captain - Namu (after all she’s his daughter) just to defeat quincy, but even with that he wasn’t able to strike down Ishida. Also in the middle of the battle he was honest enough to admit that he was the one who told shinigamis to capture Ishida’s grandpa.

Along with weird Majuri’s appearances comes his Zanpaktou abbilities. In the normal state it looks like an ordinary soul slayer but after "Kakimushire! Ashisogi Jizou!” it turns into something like Poseidon’s lance and... it just smells horribly bad... Jizou abbilites are certainly weak, cause it only can poison enemy por smell. Even it’s BanKai form is not powerfull enough to defeat ‘normal’ opponent. It reminds giant baby with blades upcoming from stomach... and it still smells awful. Despite that Majuri used to tell that he would división, split apart Kenpachi’s body in no time... yeah...

Majuri is also very self-confident and believes in his potential and abbilities. He’s also lazy in retrieving and obeying any orders and when problem is not basically connected with him, he’s not interfiering (when Aizen betrayed Gotei 13 and all captains were called to stop him, Kurotshuchi dicho ‘no, it’s not my problem’ and stayed home).

Despite that he’s quite interesting personallity and it would be great to see his battle with Urahara, since Kisuke never told anything good about Majuri and his researches...
