Reyna Diaz is one of the characters in the game Gears of War 4.
Reyna is Kait's mother and the leader of the Outsider village. She's a fierce warrior who took over her husband's role as leader after he died, and she relies on Oscar to train and protect the villagers. She allowed JD and Del to stay on at the village after they warned her of a COG retaliation to the Outsider's raids on COG bases. Along with the majority of villagers, she's kidnapped by the Swarm early on in the game, and it's up to our heroes to find her.
