Last month, Marvel Comics debuted the first information regarding the five Generations one-shots slated to arrive in August. Today, as part of its September solicitations reveal, we have the story descriptions for the latter five one-shots, including perhaps the most brain-scratching team-up of them all: Captain Marvel and Captain Mar-Vell.

Of course, as with the last batch, even with the release of the solicits, it remains a mystery as to how some of these meetings take place, particularly those involving currently dead heroes. That said, we do learn that Mar-Vell's one-shot involves a threat to the Tree, the Spider-Men issue features at least one doppelgänger, the Captain Americas story seemingly involves Sam Wilson finding himself in WWII, Ms. Marvel's story is set in the past as well, and the Iron Man/Ironheart team-up features Riri Williams finally coming face-to-face with Tony Stark, Sorcerer Supreme.
