Season 8 of The Flash has launched, with a five-episode story arc -- they're calling it a "graphic novel" -- titled "Armageddon." It is a loose adaptation of the "Armageddon" crossover that ran (no pun intended) through DC's 1991 Annuals.
For TV, The Flash is facing Despero, come from the future to destroy The Flash before he destroys the future. So far so good.
As the lords of the Arrowverse shows have decided it's too risky to do the annual crossover (because, y'know, COVID), they are making up for it by having characters guest-star during this storyline. I appreciate their diligence. Part 1 had Ray Palmer show up in Central City to accept an award at a tech fair. Ray was kind of wistful about not being with the Legends of Tomorrow, and it seemed like Brandon Routh was, too. Part 2 had Alex Danvers providing intel about Despero (and a bit of exposition saying "Supergirl and J'Onn are off-world"). And the end of Part 2 sets up an appearance by Black Lightning in Part 3.
Fans of the original Arrowverse Firestorm have reason to cheer, per Entertainment How Often Is it? Weekly?: "Robbie Amell Returning to The Flash in Season 8"
We may recall Amell's Ronnie Raymond was engaged to Caitlin Snow and they were married for about five minutes before he was killed off. Funny, Caitlin just mentioned in the last episode that aired that since Frost has a sorta-kinda boyfriend, maybe she, too should get out there and start dating.
I've only seen the first one (we'll catch up, promise), but the Supergirl representative isn't the one I would want. If we can't have Supergirl, what about Superman? Or Martian Manhunter? Or Brainiac 5?
This will probably be the last time we see anybody from Supergirl, so it's a disappointment not to see any of the big guns.
