Raid captain

A raid captain[a] is the occurrence of an illager that spawns wearing an ominous banner on its head. It is usually a pillager or vindicator, or rarely in Java Edition an evoker. They are the only renewable source of both ominous banners and ominous bottles, which they drop when killed.

Raid captains spawn in mostly the same conditions and occurrences as a regular illager, with a few exceptions.

In Bedrock Edition, a pillager raid captain can be spawned using the /summon pillager ~ ~ ~ ~ ~ minecraft:spawn_as_illager_captain command, and a vindicator raid captain (which is unused in-game) can be spawned using the /summon vindicator ~ ~ ~ ~ ~ minecraft:spawn_as_illager_captain command.
