Ed Boon, director of Mortal Kombat 11, you have posted on Twitter to hint about the next fighter to join the template: Nightwolf, a character already confirmed as part of the first Kombat Pack. No details are given about its release date.
Boon is reputed to joke and play with the fantasies of his followers, so we can not rule out that it is a false alarm, but it is clear that the imminent arrival of Nightwolf to MK11 is at least a plausible theory.
Nightwolf, for those less familiar with the game, is a fighter introduced in Mortal Kombat 3. It is strongly tied to the history of Native Americans, and fight with an ax and powers of a shaman that he cultivates in communion with nature.
