The Arrowverse Elseworlds clip is coming up very soon. The clip shows an assortment of heroes laid out over a firey battlefield. You can see Star Girl, Green Arrow (Possibly from Smallville-Verse), Firestorm, Hawkman & Hawkgirl, Ray’s mask, and Jesse Quick.
The last hero to oppose the villainous Monitor, is Earth 90’s Flash. Classic 80’s Flash John Wesley Shipp in his classic costume. The Flash makes a daring escape as the Danny Elfman theme from the old series plays in the background.

The crossover is set to begin on December 9, 2018, with The Flash, continue on Arrow on December 10, and conclude on Supergirl on December 11.
