8 Things We Want To See In The Arrow/The Flash/Legends Of Tomorrow/Supergirl Crossover

2) Constantine Returns

I’ve already outlined why I would love to see Matt Ryan’s John Constantine in Legends of Tomorrow, but if for some reason that isn’t possible (likely because Warner Bros. has plans for him on the big screen in that long rumoured Justice League Dark movie), then a one off appearance here wouldn’t go amiss.

It’s something which would further expand the DC TV Universe and he could very well be given a pivotal role to play in the four part story if the foe all these heroes team-up against is somehow tied to the world of magic.

The point is, Constantine’s story on the small screen ended far too soon, and Matt Ryan was too damn good in the role to just leave on the shelf. Fans loved seeing the demon hunter return in Arrow, and if The CW could make that happen, there’s really no reason why it couldn’t again.

And, if it leads to him joining the cast of Legends, even better.
