The CW has released a triptych poster for this year’s DC series crossover event ‘Elseworlds’ featuring The Flash, Iris West-Allen, Vibe, Killer Frost, Green Arrow, John Diggle, Felicity Smoak, The Monitor, Batwoman, Superman, Supergirl, and Lois Lane. Oh, and there’s also a mystery robot-looking character in there too… any ideas?

And here it is combined…

‘Elseworlds’ begins with The Flash on December 9th, followed by Arrow on December 10th and Supergirl on December 11th. In addition to Grant Gustin (The Flash), Stephen Amell (Green Arrow), Melissa Benoist (Supergirl) and their fellow series regulars, the three-parter will feature guest appearances from Tyler Hoechlin (Superman), Ruby Rose (Batwoman), Elizabeth Tulloch (Lois Lane), John Wesley Shipp (Jay Garrick/The Flash), Cassandra Jean Amell (Nora Fries), LaMonica Garrett (The Monitor), Bob Frazer (Psycho-Pirate) and Jeremy Davies (Dr. John Deegan).
