Johnny Cage's And Cassie Cage's "Rage Mode"
While I personally dislike (not hate) Johnny Cage and my dislike for Cassie Cage stems from her paternity (which I think Sonya was better as a character than her daughter). Now moving on, we do have the "Rage Mode" of Johnny Cage and Cassie Cage which happened in Mortal Kombat X's rather not so impressive story mode. Yeah I know, I'm a Liu Kang fanboy!
Yeah I know the Story Mode is weak for me considering that I wish Raiden powered them both up or maybe the Elder Gods do so before this storyline can be more acceptable to me.
