The Arrowverse crossover event has become an annual fixture in the TV calendar and this year is no different, but the stakes are higher...


The crossover event, Crisis on Infinite Earths, promises major deaths as well as more cameos than you can shake a stick at. The crossover also falls within Arrow's final season so expect the five-part TV event to go all out.

The core Arrowverse shows are all taking part with Arrow, The Flash, Supergirl, Legends of Tomorrow and the new Batwoman series with Ruby Rose making up the core episodes, with a cameo by Black Lightning.

Three parts have already aired, and the event will continue on January 14, 2020 with Arrow and conclude with Legends, which will follow straight after.

Here's what we know about the Crisis of on Infinite Earths crossover so far.

When will Crisis on Infinite Earths air?

Crisis on Infinite Earths has already aired - well three parts - in the USA. The Arrowverse crossover has historically fallen around the Autumn time, but this time around the air dates are split between December and January to take the Arrow finale into account.

At The CW upfront presentation back in May, network president Mark Pedowitz confirmed it would begin in December but conclude after the break. In total it will clock up to five-hours of TV and cover every show.

The Crisis on Infinite Earths episode isn’t the Arrow finale. Arrow season 8 is only 10 episodes long, but the crossover with fall on the eighth episode of the season leaving two episodes to follow.

Crisis on Infinite Earths episode order and air dates

Supergirl – Sunday, December 8 at 8pm

Batwoman – Monday, December 9 at 8pm

The Flash – Tuesday, December 10 at 8pm

Midseason break

Arrow – Tuesday, January 14 at 8pm

What is Crisis on Infinite Earths about?

The Arrowverse is adapting the classic comic Crisis on Infinite Earths by Marv Wolfman and George Perez from the '80s. The original story was about The Monitor who oversaw the entire multi-verse. He was tasked with gathering the best heroes from each ‘verse to send into space to defeat his brother Anti-Monitor. The Anti-Monitor’s aim? To destroy the entire multiverse.

We were introduced to The Monitor already in last year’s Elseworlds crossover, which involved him making a deal with Oliver Queen where the Green Arrow offered up his life in order to save Supergirl and The Flash. The Monitor then cropped back up to collect Oliver while he was hiding out in a cabin with Felicity and their daughter.

In the comics, there are seven Paragons - the Monitor calls these people the "beings of purest will". Some of these are rather close to home...We won't reveal who they are here just in case you're watching along with the UK Sky air dates.

This isn’t even a spoiler as in Arrow’s season 7 finale we finally found out the deal Oliver made with the Monitor (LaMonica Garrett) back in Elseworlds.

Monitor told Oliver that the Crisis would mean his life, and then in the flash-forwards, as Felicity and their kids stood at Oliver’s tombstone, we saw his death date... 2019.

We'd add, this is Arrowverse, nothing goes the way you think it will...

Crisis on Infinite Earths spoilers

  • We will find out about Barry’s future disappearance which has been teased by the newspaper headline. We already know The Flash disappears in a crisis, but that’s all - that's a clue
  • Exec producer Todd Helbing has now said this is when we finally get our answer. In The Flash’s season 5 finale we also saw the headline date change from 2024 to 2019, aligning it with Oliver’s death and the crossover.
  • There isn’t just one Superman, there’s three. Tyler Hoechlin already stars as Superman in Supergirl, but the crossover sees Brandon Routh, from the 2006 film Superman Returns, also suit up. He already plays Ray/The Atom in Legends of Tomorrow, but he will play Superman in a different timeline for the crossover. Tom Welling, who played Clark Kent/Superman in Smallville, reprises that role.

  • Speaking of alternate roles, Tom Cavanagh stars as Reverse Flash and a new version of Harrison Wells on this season of The Flash, but he also plays a new character for the crossover, called Pariah. In the comics, Pariah is a scientist from an alternate universe that sets Anti-Monitor loose.
  • Elizabeth Tulloch returns as Lois Lane, but the bigger news is her baby with Superman will also make an appearance - he's called Jonathan after Clark's dad.
  • Kevin Conroy, who voices Batman in the animated series, is finally playing the Caped Crusader on-screen as he’s been cast as an older Batman for the crossover event. He's a very different version though.
