Raid captain

A raid captain is the occurrence of an illager spawning with a Ominous Banner‌ on top of its head, usually a pillager or vindicator, or rarely an evoker.

Spawning
Raid captains spawn in the same conditions and occurrences of any illager, with no special occasions having one spawn and one spawning being completely randomized.

Illager patrols
One raid captain always spawns as part of a illager patrol, either a pillager or vindicator. In Bedrock Edition, if the difficulty is set to easy or normal, raid captains are always pillagers.

Raids
As part of raids an raid captain will spawn as a part of a group of pillagers, and sometimes spawn riding ravager. The captain will not cause another raid if killed, but when its banner drops, other illagers will rush to grab it.

Pillager outposts
Usually, 1-3 raid captains will also spawn in a pillager outpost - these are always Pillagers.

Woodland mansions
Raid captains can also spawn in woodland mansions, which are either vindicators or evokers.

Behavior
Raid captains usually act the same as if they were a normal illager, but other illagers behind them will follow them and usually, the captain will take the lead ahead of the other illagers. Once a raid captain is killed by a player, the player will be inflicted with 1 level of bad omen effect, which can cause a raid to occur if they enter a village. The captain will drop its Ominous Banner‌ as well, and other illagers nearby will try and pick up that banner and become the next captain.

Raid captains are designated differently, depending if they spawned at a outpost or in a illager patrol. Both patrol and outpost captains grant one level of Bad Omen when killed.

Trivia

 * Despite raid captains wearing the Ominous Banner‌ on their heads, they actually wear it in chestplate slot.
 * Though they are unused, illusioners can also be spawned as a raid captain.
