My favourite characters are not part of the roster stables, so I’m forced to be rather flexible when it comes to maining characters in MK.
MKX pre-DLC had none of my faves, however, it did have Kitana and Mileena which I’ve always liked, so I at least had those to play. I also like Ermac, Kenshi and Reptile, but again, they’re not my go-to characters. However, I found a new favourite in Takeda who became my main until Tanya became DLC who then became my main, as she’s indeed one of my favourites. I also very much liked Smoke in MK9, so played Triborg’s Smoke variation a lot too… but I absolutely hate Triborg as a character and hope he will never return and forever be non-canon.
I don’t think Tanya will return, but Jade seems to have a high chance of being on the main roster of MK11, and since she’s my top fave, she’s definitely gonna be my main. ^^
