The first Kombat Pack had six, the second had 3, so I’m thinking the next one will be somewhere where in the middle let’s say 5. KP1 had 3 Guest Characters and KP2 had 1. So I’m gonna say 2 out of 5 are guests.
Here are mine
Havik: It’s been a long time since we’ve seen Havik, the only thing we know about him recently is in Joker’s Story Ending, and as a Easter Egg in Aftermath when Shang Tsung sends Geras to the Chaosrealm. It would be awesome to see Havik again and his twisty body would make some sick combos and fatalities.
Sareena: She appeared in MKX and we know she is still in the current timeline. It would be nice to know more on Sareena’s backstory maybe even to see her demon form. And she would make some sick dialogue from Noob and Subzero.
Reptile: We’ve seen Reptile in the Krypt, it’s a nice cameo with a reference to the 1995 Mortal Kombat movie but Reptile deserved more. Reptile was one of Kotal Kahn and Outworld’s most revered warriors but he was nowhere to be found in Mortal Kombat 11’s two campaigns. Plus the customization would be sick.
John Wick: John Wick was also a guest character in games like Payday 2 and Fortnite, so there’s a good precedent for his appearance. Cyberpunk 2077 also proves that actor Keanu Reeves is not against appearing in games. Keanu would likely be all for providing the motion capture for John Wick as well. Altogether, John Wick would be an awesome character to see in Mortal Kombat.
Ash Williams: When DLC leaks first came out, originally Kombat Pack 1 was said to feature Ash Williams from the Evil Dead franchise. Since Mortal Kombat X excelled with its horror characters, everyone was excited. However, though every other DLC character rumored to appear did so, Ash did not manifest. Ash is an iconic eighties hero much like Terminator, Rambo, and RoboCop so he would fit right in. Ash would also be Mortal Kombat 11’s first horror character. His mix of chainsaw and shotgun-based combat would make for some fun gameplay. Of course, Ash’s signature silly yet awesome banter would make for him rivaling Johnny Cage for the funniest character.
