The Flash Showrunner Wanted The Blackest Night Crossover For The Final Season

As The Flash has just wrapped up its nine-year run on The CW, showrunner Eric Wallace is revealing some of the plans that never quite came to fruition. This includes a proposed Blackest Night crossover that would have connected several live-action DC series.

Wallace spoke to EW about the plot points that weren’t picked up in the truncated season 9, as well as what could have happened in a hypothetical season 10. The Blackest Night crossover would have brought together characters from Superman & Lois, Stargirl, and even Titans, suggesting the multiverse would have been a major focus.

“Back in Season 8, we set up The Blackest Night storyline with Deathstorm,” Wallace told EW. “When Deathstorm was defeated, the emotional vibes went up to the Netherverse and another dimension to Nekron, which is straight out of the comics. I’m on a show or not – back together for this storyline. This what it would have allowed me to do is to bring back characters who died.

Blackest Night is a 2009 crossover helmed by writer Geoff Johns and revolving around the Green Lantern franchise. When Nekron summons various dead heroes and villains to join his Black Lantern Corps, Hal Jordan is forced to unite the various other Lantern Corps to stop this undead army. Given the lack of prominent Green Lanterns in the Arrowverse and shows like Stargirl and Titans, this TV adaptation would presumably have downplayed the Lantern elements (although it’s still possible that David Ramsey’s John Diggle eventually joined the Green Lantern Corps).

Wallace also revealed that The Flash: Season 10 would have opened with a conflict called Forever War, with Team Flash battling the Chronarch, the tyrannical villains who banished David Dastmalchian’s character, Abra Kadabra, from the 64th Century. This conflict was hinted at in seasons 7 and 8 but never seen on the show.

“It’s one of those crazy things that I alluded to that’s very much related to the Chronarch,” Wallace said. “We hinted that the Chronarch would be back one way or another, as far back as Season 7 when Abra Kadabra mentions to Barry, ‘The Chronarch is coming and will ruin your life.’ It has to do with Barry and Iris because eternity crumbles and eternity is swept away.It would have kicked off season 10 with a few special guests we would have seen.

Wallace named other plot threads had to be scrapped due to Season 9’s shorter format. Chester’s computer files are hacked. Danielle Panabaker’s Khione was also supposed to have a more in-depth origin story.

Finally, Wallace revealed that there were several Flash veterans he hoped to bring back for the final season, including Jordan Fisher as Barry and Iris’ future son, Bart. He also had plans for Shantel VanSanten’s Patty Spivot and Tom Felton’s Julian Albert, who would return to the fold as a married superhero duo.

What do you think of these abandoned projects? Do you wish The Flash had stuck around long enough to deliver their own version of Blackest Night? Let us know what you think in the comments.
