Stormguard

First seen in the Tomb Raider (2013) video game, the Stormguard (also known as Oni) are an organization of samurai who are sworn to serve and protect the Sun Queen of Yamatai, even after her soul is trapped in a decaying body. Legend has it, the Sun Queen was able to conquer the lands of Yamatai thanks to her Stormguard, who were unmatched in combat. Using the Sun Queen's power over the sun and rain, she would raise up a mighty storm that the Stormguard would ride upon to destroy their enemy. Before the ceremony to transfer the Sun Queen's soul into another, more suitable body, they were planning to cross the ocean to touch all lands.

The Stormguard General was their leader until he committed seppuku on the death of the Sun Queen's bodily successor. Upon Lara's arrival, the Stormguard Stalker appeared to be the leader as he was seen at the head of the Stormguards when preparing for battle, sending guards after Lara when she was detected, and he would roar an unearthly howl to signal a new wave of Stormguards to fight Lara.

Clad in medieval samurai armor, these humanoids seem to be hostile to every outsider, including the mysterious man known as Mathias, and his cultists.
