Boomer is the dog from Far Cry 5, back in Far Cry 6 as a stealth Amigo that Dani calls Boom-Boom. He tags enemies around you and pulls loot off bodies, which makes him the best pick for scouting a base before you go in.
In Far Cry 5 Boomer belonged to Rae-Rae's pumpkin farm and joined the resistance after Eden's Gate killed his family. In Far Cry 6 he is one of the original Amigos, a stealth and recon companion.
You find him while hunting American weapons in the Yaran Story Boom or Bust. After that he is available from the Amigo menu like the others.
Send Boomer ahead and he marks soldiers and wildlife, so you see the whole layout of a checkpoint without using your phone. His fetching perk keeps crafting materials flowing during long fights. Pair him with suppressed weapons for quiet base clears.

Chicharrón is a punk rooster Amigo raised for cockfights who would much rather peck FND soldiers. You earn him in El Este by helping with his grudges against the regime.

Chorizo is Philly Bárzaga's dachshund pup in a custom wheelchair, and one of the best stealth Amigos in the game. He distracts guards so you can walk up and take them out quietly.

Guapo is Juan Cortez's pet crocodile and one of the first Amigos you get. He is tough to keep down, since he can revive himself, which makes him a reliable attack partner for loud fights.
Oluso
Oluso is a spirit black jaguar blessed by the Oluwa, Yara's divine triad, and one of the hidden Amigos you can recruit. Getting her means returning three sacred relics and then beating her in a fight.
