It's almost time for the Crisis on Infinite Earths crossover event. In celebration, The CW has released the synopses of the first three episodes and an epic movie-style poster that looks like a riff on Avengers: Endgame. There's only two weeks left for fans to get their first look at the highly anticipated annual event. It seems that the network has really outdone themselves this time around because everything looks massive.

Supergirl Episode 5.09 is titled Crisis on Infinite Earths: Part One. The Arrowverse episode is directed by Jesse Warn from a story by Robert Rovner and Marc Guggenheim wrote and teleplay by Derek Simon and Jay Faerber. From the sound of things, Melissa Benoist is going to have a lot of help before things start to get really bad. Since their worlds are in imminent danger, the crew is going to need all of the help they can get. You can read the synopsis below.

"The Kickoff To The Epic Television Crossover Event, Crisis On Infinite Earths - The Monitor (guest star LaMonica Garrett) sends Harbinger (guest star Audrey Marie Anderson) to gather the worlds' greatest heroes - Supergirl (Melissa Benoist), The Flash (guest star Grant Gustin), Green Arrow (guest star Stephen Amell), Batwoman (guest star Ruby Rose), White Canary (guest star Caity Lotz), The Atom (guest star Brandon Routh) and Superman (guest star Tyler Hoechlin) - in preparation for the impending Crisis. With their worlds in imminent danger, the superheroes suit up for battle while J'onn (David Harewood) and Alex (Chyler Leigh) recruit Lena (Katie McGrath) to help them find a way to save the people of Earth-38."

Batwoman Episode 8 is titled Crisis on Infinite Earths: Part Two. The episode is directed by Laura Belsey from a script written Don Whitehead and Holly Henderson. Kevin Conroy is guest starring on this special episode and comic book fans are already excited to see what he brings to the table in this bonkers storyline. Jon Cryer is even back as Lex Luthor for the annual crossover event. The synopsis can be read below.

"Can the Real Clark Kent Please Stand Up? Part 2 of Crisis on Infinite Earths Continues With Special Guest Stars Tom Welling, Erica Durance, And Kevin Conroy - The group uses Ray's (NEeQ4caab72Tgk||guest star Brandon Routh) invention to track new recruits to help save the universe.

Finally, The Flash Episode 6.09 is titled Crisis on Infinite Earths:Part Three. The episode is directed by David McWhirter from a story by Eric Wallace and teleplay by Lauren Certo and Sterling Gates. Keeping with the spirit of the first two installments, the third chapter is packed with guest stars. Black Lightning is joining the team this time around for what should be an action packed episode. You can read the synopsis below.

"Black Lightning Joins the Arrowverse In The Third Chapter of the Crossover - Pariah (Tom Cavanagh) enlists Black Lightning (guest star Cress Williams) to help stop the Anti-Monitor (guest star LaMonica Garrett) after Flash-90 (guest star John Wesley Shipp) shares what he learned from his battle in Elseworlds. With the help of Black Lightning, Barry (Grant Gustin), Cisco (Carlos Valdes) and Killer Frost (Danielle Panabaker) come up with a plan that could save them all. Meanwhile, Iris (Candice Patton) has a heart-to-heart with Ryan Choi (guest star Osric Chau), while Oliver (guest star Stephen Amell) and Diggle (guest star David Ramsey) return to an old familiar stomping ground."

The Crisis on Infinite Earths crossover event will kick off on December 8th with Supergirl. Part 2 will take place during Batwoman on December 9th and The Flash takes part 3 on December 10th. The event will then take a winter break and return in January with Arrow and Legends of Tomorrow. This year's event is going to be the biggest yet. The story information was provided by The CW.
