DC's Legends Of Tomorrow: 10 Arrowverse Characters Who Should Join Season 2
2. John Constantine
Appeared In: Constantine, Arrow
In the fall of 2014, NBC launched their own take on Hellblazer, with the Matt Ryan-led series lasting all of 13 episodes before coming to a premature end. Miraculously, though, Constantine lived on, with Ryan making the leap over for an appearance on Arrow earlier this season that left fans wanting more, retroactively making the cancelled series part of the Arrowverse in the process.
Since then, many have been wondering when (or if) we'll be seeing him again, and while it seems unlikely that The CW has any plans to try and bring his series back to life anytime soon, it's hard to imagine the gears aren't spinning on how to bring him back on a more regular basis across the Arrowverse, especially since he's continued to be name-checked ever since. Though any future appearances big or small are welcome, having the practitioner of the occult brought onto the Legends team for season two would be a great way to really elevate his role, and seeing him interact with the gang - and out-trench coat Rip Hunter - would be more than worth it.
