The t1000 would become Jason Todd and use his body like in the movie and have him remember that Jason was his greatest failure and also the t1000 can even be any one else in the batfamily to kill Bateman so Batman won't know who's who in the fight
yeah even if Doctor Strange did manage to banish Dr Manhattan he could just come back and win against doctor strange while he's recovering from losing too much energy Doctor strange wouldn't be able to land a single blow only magic which would be futile against Dr Manhattan.
When looking at the films and also the statistics they are quite evenly matched. Abominations of the universe born killing machines. In the forest Predator is far superior maybe taking out four or five Aliens. In an open range its much closer and i think Predator will have a hard time against two Aliens and be defeated against three. In the film it was close in a one on one battle.
