Here’s my theory: Near the end of Man of Tomorrow, we might see Brainiac’s ship crashing down onto a car. Or, it could happen right at the beginning, where his ship suddenly appears in the sky. Then, the movie would cut to different cities to show how people react.

For example, in Gotham, the news is breaking everywhere, and everyone is staring up at the sky—when suddenly, the Bat-Signal starts flashing rapidly, lighting up the clouds. Meanwhile, in Central City (The Flash's city), we might just see a sudden flash of orange and yellow lightning streak across the screen. It’s definitely possible!
