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

The annual crossover between Arrow and The Flash has become a staple of The CW's winter schedule, but things look set to get even bigger this year with the confirmed four night event which will add the Legends of Tomorrow and Supergirl into the mix. We're still months away from plot details being revealed, but the possibilities for this are seriously endless. With all of these characters sharing the screen at the same time, it's clear that this crossover is going to be huge, and there are a lot of very exciting things that may happen as a result. What you'll find here then is a look at the eight things we most want to see in this epic team-up between Arrow, The Flash, Legends of Tomorrow and Supergirl. From cameos to the storyline it should be based on and the villain who most deserves to take centre stage, seeing just a few of these become a reality would go a long way in making this event even bigger than Justice League. That may seem like a bold statement, but when you take into account the amazing things these shows have done so far, it's easy to imagine it being the case.... 8) Superman As of right now, Tyler Hoechlin has only been confirmed as appearing in the first two episodes of Supergirl's second season. With that show making the leap to The CW, it makes sense that they want to get viewers to tune in those first two weeks for the Man of Steel and then stick around moving forward, but it's hard to imagine the character just vanishing when that fortnight concludes. Not including him in this four night event would be a huge blunder on the network's part, because as great as Supergirl is, seeing The Flash and Green Arrow standing alongside the new small screen Superman is even more exciting (and something it's fair to say not a single one of us ever expected to see six months ago). Even if he only has a glorified cameo over these four nights, Clark Kent making his presence felt in this crossover is a must and would make it a truly special event for fans. 7) The Legends Save The Day The Legends of Tomorrow being part of this crossover is very exciting indeed, and it should be a priority to have them play a key role in whatever threat all of these heroes assemble to go up against. It would be too easy to make characters like Green Arrow, Supergirl, and The Flash the ones who save the day, and having these more obscure, B-List characters (which is how they're also viewed in their own reality, hence why Rip Hunter recruited them in the first place due to their disappearance having no significant impact on the timeline) be the ones who step up is a must. Whether they swoop in at the last minute or play a pivotal role in this adventure from the off, it would be a refreshing change of pace to see the likes of Rip Hunter, Heat Wave and White Canary be the ones who steal the show from the bigger name heroes. It would actually go a long way in helping to legitimize them, too. 6) The Anti-Monitor The Anti-Monitor is an incredibly powerful cosmic being who is perhaps best known for being responsible for the original Crisis on Infinite Earths. He controls the Antimatter Universe and wants nothing more than to destroy the positive matter Multiverse, killing untold billions in the process. Bringing together all of these heroes demands a threat worthy of their attention, and with Zack Snyder's Justice League franchise putting the focus on Darkseid and Apokolips, there's definitely room for the Anti-Monitor to show up here. The network has brought to life a fair few CGI baddies now, including Gorilla Grodd and King Shark, so a giant version of this character looming over the Central City wouldn't be too much of a stretch. There's another good reason as to why he should appear though, and that's an adaptation of the storyline mentioned at the start of this slide: A Crisis on Infinite Earths. 5) A Crisis On Infinite Earths One of the biggest questions fans have been asking ever since it was revealed that Supergirl is coming to The CW is whether the hero will remain in her own separate world or somehow be brought into the one that Green Arrow and The Flash call home. The latter option would certainly make future crossovers easier, and this four night event being about combining these realities would actually work really well as it gives The CW time to wrap up the stories started by Supergirl season one and then have her in new world after the Winter hiatus. To make this a possibility, some sort of loose adaptation of A Crisis on Infinite Earths would be perfect. Both Supergirl and The Flash played a key role in that story, and having the Anti-Monitor destroy Kara's Earth or somehow end up combining it with Earth-1 would solve a lot of problems and be truly epic for fans to see. 4) A Major Character Death The death of Black Canary in Arrow did not go down well, though that was mostly because the show killed off its best female character instead of the two who have become unbearable (Felicity and Thea). If this four night crossover is indeed going to be some sort of epic event unlike anything we've seen on TV before, then it needs to have ramification, and the death of a beloved character would go a long way in ensuring that so long as it's not just done for the sake of it. Captain Cold's demise in the season one finale of Legends of Tomorrow showed the best way to handle this type of thing, and providing one of these shows can find an equally epic and emotional way to say goodbye to a hero, then it should happen here, especially if it has an impact on whichever show they hail from moving forward. It's hard to say who this could be, but a Legend seems most likely. 3) Green Arrow Meets Supergirl Stephen Amell has been talking about his desire to have Green Arrow team-up with Supergirl for some time now, and while seeing Barry and Kara reunite is essential, Oliver meeting the Girl of Steel has a lot of potential. For starters, it's fun to imagine how these two very different characters will interact and what Oliver Queen will make of this God like being. And how about how Supergirl will react to a non-powered vigilante, something she hasn't encountered in her world? These two teaming up would be a lot different to what we've seen in both shows in the past and creates a much more interesting dynamic than revisiting the one we've already had a taste of between her and the Scarlet Speedster. Honestly, this meeting is pretty much an inevitability, but what I really want to see is The CW making it a memorable moment as their original hero meets their newest. 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. 1) The Flash Races Superman The all too brief crossover between The Flash and Supergirl wrapped up with a brief race between the Girl of Steel and Scarlet Speedster which was used to send Barry Allen back to his Earth. A rematch wouldn't go amiss, but The CW could make history by having The Flash find out who the Fastest Man Alive truly is by squaring off with Superman himself. That's something which has happened many times in the comic books (where it's been established that Barry is definitely faster), but never in live-action. Smallville tried it, but Clark wasn't wearing a costume and he was squaring off with Impulse, so it's not exactly the same thing. If the showrunners really want to have some fun, they could throw Supergirl into the mix too, but a race between these heroes would make for the perfect ending to the crossover and ensures it's something fans talk about for a long time.
