Well Mon-El has no use to anybody and just hogs screen time for his selfish behaviour. He barely even uses his powers.

Yes, he is a part of it. However he doesn't have a big role. Just because he isn't on the cover, doesn't mean he isn't in it. Alex is having a big role, but they aren't featuring her on either. Though J'onn will not have a role like Alex in the crossover.
