Nightwolf

Grey Cloud, better known as Nightwolf, is a character in the Mortal Kombat fighting game series. He made his debut in Mortal Kombat 3, and has become one of the most prolific Native American characters in video games.

Nightwolf is a Matoka warrior who, although introduced as a historian and a shaman, does not live in the past. He is a proud and fierce warrior dedicated to the cause of good, and is in contact with Raiden through visions. As such, he draws on both internal and external spiritual energy to enhance his power.

Originally, his tribe was Lakota-Sioux (hence why he refers to Raiden by 'Haokah'), but this was later retconned in Mortal Kombat 11. He is now a member of a fictional tribe called the Matoka.

In Defenders of the Realm, he owns a pet wolf named Kiba; in Annihilation, he taught Liu Kang how to find his Animality, even though he functioned as a jerk.
