You may scoff at the idea of an article on how to watch Crisis on Infinite Earths online, but trust us - it's confusing. That's because the massive crossover event between multiple DC TV shows isn't a series in itself. Instead, it's spread out across multiple seasons and franchises like Arrow, Batwoman, Flash, and Supergirl.

That's why we've put together this explainer on how to watch Crisis on Infinite Earths online; we'll take you through the recommended viewing order and give you the lowdown on where to find each episode. There's advice on how to stream Crisis on Infinite Earths if it's not normally available in your region, too. And if that fails? Well, there's always the DVD.

Crossover events between DC's TV shows isn't a new concept, but this one is definitely the most ambitious. It draws in characters from every corner of the DC superhero multiverse, and they're tasked with stopping classic villain the Anti-Monitor from destroying all life - in every universe. 

Part of the fun is its broad scope; rather than limiting its cameos to current shows, it features the universes of Smallville, 1989's Batman, the 1966 Batman series, and beyond. The crossovers go beyond TV, too. Brandon Routh's Superman makes a comeback (portraying the same version of the Man of Steel from Superman Returns and the original films), and a certain figure from the DCEU Justice League also drops in.

To get you started, here's the correct viewing order so you can watch Crisis on Infinite Earths online as the creators intended:

Watch Crisis on Infinite Earths online - Part 1

Part 1 of the Crisis of Infinite Earths crossover occurs in Supergirl season 5, episode 9. A mysterious cosmic figure known only as 'Harbinger' brings together DC TV's greatest heroes to battle the Antimonitor. If they fail, the multiverse - and everyone in it - falls.

Part 2 of Crisis on Infinite Earths is a doozy. It can be found in Batwoman season 1, episode 9, and it features a ton of cool cameos. Not only does it feature Tom Welling and co from Smallville, it adds in Brandon Routh's Superman and Kevin Conroy (who portrayed Batman in the 1990s animated series and the Arkham games) as Bruce Wayne.

The story continues in The Flash season 6, episode 9. Part 3 draws in more heroes to the cause, including 1990's TV Flash, John Constantine from the short-lived show of the same name, and the much more recent Black Lightning. Things are really ramping up, and Earths across the multiverse are being wiped from existence.

Things go from bad to worse in Part 4 of Crisis on Infinite Earths. You can see for yourself in Arrow season 8, episode 8 as the remaining heroes - the 'Paragons' - attempt to fix an impossible situation.

Watch Crisis on Infinite Earths online - Part 5

This is it - the final part of Crisis on Infinite Earths takes place in Legends of Tomorrow season 5, episode 1. It's not an exaggeration to say that things will never be the same again.
