NetherRealm announced at San Diego Comic-Con some of the guest characters that will appear in Mortal Kombat 1 as part of its first DLC pack.
These characters are Homelander, Invincible's Omni-Man, and Peacemaker. Mortal Kombat characters included in the pack are Erma, Quan Chi, and Takeda.
Homelander will look just like he does on the Amazon series, and the DC universe character Peacemaker will resemble John Cena's character in the HBO Max series.
