Flash

Here is the character I have the highest hopes for. In both scene descriptions from the set, Flash is the one to lighten the atmosphere. Not only that, but he is also one of the characters with whom Batman develops a stronger relationship. According to the reports, it seems that Flash is a Dark Knight fan.

In any way, you can check out the scenes here.

As far as his suits are concerned, he will wear two of them in Justice League. The first one is, as expected, designed by Flash himself, and is very red in color, more vibrant than the one from the TV show. And it is designed to be as functional as possible. Besides being very aerodynamic, it is also laced with wires, which are supposed to both hold it together at high speeds, and conduct all the energy generated while he is running.

The second suit, which resembles what was seen in Batman v Superman, is designed by Bruce Wayne.
