User blog:Xandermcc/Potential crossovers coming soon (SPECULATION)

So Crisis On Earth-X and Daddy Darhkest may seem like the only crossovers we are getting for a while, but i believe some might be coming up soon. Here are my theories on the next two crossovers happening this year. Keep in mind this is all speculation on my part.

Invasion of Superboy-Prime
The annual Supergirl/Flash crossover has still not happened yet. Usually it is around the 18th episode of both shows. So we still might get that. However what would it be about? After you have someone as godlike as this Music Meister taken down, who is next? I believe it is Superboy-Prime. The teasing of it certainly hints at that happening. The plot would be leading off the events of both shows. After Team Flash had accidentily ravaged Superboy-Prime's world with radiation, he comes to Earth One for revenge. Barry calls Kara over in order to help stop him. However due to her lack of confidence after her constant battles with Reign, she will need the teamwork of both her team and Barry's to stop Superboy-Prime.

It looks like a pretty awesome crossover to me.

Black Lightning and the Manhunter from Mars
Another potential crossover with Supergirl is the start of a connection with CW's Black Lightning. Showing that these world are in fact connected. The one problem however is the large distance between sets. So you would need someone motivated to do this. I can't think of anyone else except David Harewood. Who so far is a big fan of Black Lightning. Someone who would probably make the trip to Atlanta to do this crossover. As Black Lightning might need help in his upcoming battles with Tobias Whale and the 100 and who is better to do that than the Martian Manhunter?

So what do you think of these crossovers? Do you think they both are possible or are they both too unlikely?
