Justice League writer Scott Snyder shared a piece of artwork teasing a showdown between Lex Luthor and the Martian Manhunter in an upcoming issue of the series.
In a post on Twitter, Snyder shared the art, which was created by British comic book artist Jim Cheung. The image shows Martian Manhunter and Lex Luthor staring each other down. Luthor appears to have a weapon of some sort, which Martian Manhunter has put his hand on top of. Alongside the post, Snyder wrote, "Coming up in Justice League art by #jimcheung High Noon on Mars."
The artwork will presumably appear in Justice League #17, which will be Cheung's sixth issue on the current run. The synopsis for issue 17 gives some context for the artwork:
After the disastrous events of the Justice League Annual, Martian Manhunter decides to take matters into his own hands and negotiate a peace with Legion of Doom leader Lex Luthor. Traveling to a distant moon, the two enemies face their intertwined pasts in a showdown for the fate of the Multiverse. However, before either of them can lay claim to the power of the Source Wall once and for all, an unexpected threat forces them to unite…or risk death at the ends of the cosmos.
The showdown between Luthor and Martian Manhunter is part of the lead-up to "The Sixth Dimension," a six-part story beginning in Justice League #19. That story will see DC's greatest heroes enter the Sixth Dimension to square off with their older selves.
Written by Scott Snyder and James Tynion IV and illustrated by Jim Cheung and Mark Morales, Justice League #17 goes on sale Feb. 6. Cheung will handle cover art for the issue, with Will Conrad creating a variant cover.
