User blog comment:Xandermcc/Potential crossovers coming soon (SPECULATION)/@comment-26618197-20180215233522

Superboy Prime could work but he seems like a four way kind of guy. Besides, I think it's about time some of team Flash go to Earth 38 because I seem to recall, after the Earth X crossover, someone saying that the cast wanted to go over to Earth 38 for a change. Although if they did do Superboy Prime they could have him set up a future four way crossover by punching the barrier between realities.
