5 Best DC Universe Crossovers (In Film & TV)

4. Crisis On Earth X

One of the Arrowverse’s now most anticipated moments are the annual crossover events. Crisis On Earth X, released on DVD earlier this month, proved to be the most epic one yet, with a mammoth four-episode that spanned across Supergirl, Arrow, The Flash and DC’s Legends Of Tomorrow.

In addition to the Arrowverse regulars, Crisis On Earth X also introduced the first live-action appearances of The Ray and the Freedom Fighters, the latter being another superhero team from DC who in this instance show up as their evil counterparts from the parallel world of Earth X.
