Arrowverse would be redundant because Ace West (black Wally West) and the Dreamer are canon already.

True, but Joe West and Harrison Wells aren’t.

Uhhhh none? All of them would be, in one way or another, redundant

Is Earth-0 the Prime Earth?

Yes.

Hmm... I'm tied between Earth-93/Earth-M, Arrowverse, and Earth-4.

• Earth-5 is cool but it's too much lol

The milestone characters still technically exist in Earth 0.

In my case, the milestone universe, would love to see static rocket and icon and the rest of those milestone characters in one universe with DC
