lets take a re-look at the story trailer shall we? i want to discuss the likley hood of rain, baraka, and Fujin
boon said there would be 5 reveals in it we have:
Kung Jin
Jaqui
Takeda
Mileena
Erron Black
except now its confirmed that 3 others that were in that trailer were confirmed as well:
Shinnok
Johnny Cage
Sonya Blade
Boon said 5 reveals, but he didn't say "only 5" and when asked to specify he replied back "sure are a lot of NPCs in that trailer" and he was right there were a lot of NPCs, in fact there were armies of them. nearly every character that appeared in that story has been confirmed playable now and they all have altered appearances. even when Kitana and Sindel are fighting you can clearly see Kitana has a new costume, same goes for Jax in his evil form. this implies that if you have a new costume you'll be playable.
Rain and Baraka both have this requirement infact Rain has one better in that he almost died in the comics. keyword is "almost" unlike Hsu Hao who was instantly killed Rain was kept alive because Boon wanted him in MKX for some reason and their is typically only one reason you want someone in your fighting game.
Another thing of note is this isnt MK4, Fujin isnt needed yet why is he here?
TL;DR i predict Rain, Funjin, and Maybe Baraka to be playable.
oh also pretty sure the Frost pic is legit, as ugly as the pic is it matches the quality of this video
that took forever to type up, time to binge more Hunter x Hunter till 3pmCST
