How do you become captain in bleach?

Answer 1

1. To take the captain proficiency test which requires the ability to perform the bankai. Presumably, most Soul Reapers become captains using this method. At least three existing captains, including the Commander-General, have to witness the test.

2. To have personal recommendations from at least six captains and approval from at least three of the remaining seven.

3. To defeat a captain one-on-one with at least 200 witnesses from the captain's division. Kenpachi Zaraki is the only known captain to have achieved his rank using this method.
