That picture is of Richard Rider with full Nova Force and Worldmind. Having the Worldmind is as good as adding a third character with intelligence even higher then Reed Richards. With Worldmind, Nova can calculate equations in seconds to open a warp-gate and BFR for a win.
I am going with Nova and Ghost Rider here... GR will eventually take down Scorpion... I don't think it will be that easy because of the Nature of Scorpion outside of just his Mortal Kombat gameplay... Nova should be able to beat Green Lantern Hal Jordan... but this could be a very very good fight.
