Currently, Invincible season 2 is running the first 4 episodes of the 2nd season, and then take a break to return in 2024. In the next episode, Mark is going to meet with his father again, and then return to earth. In the episode, I believe Mark is going to fight Angstrom, where Angstrom sends him through various portals. Which happens in the comics. At the same time, Marvel published “Marvel Team-Up: Volume 14”, where Invincible is sent to a Marvel universe, and he teams up with Spider-Man.
During December, Marvel is once again running another season of “What If?”, where they explore different possibilities within the Marvel Multi-Verse.
I believe that during the break of invincible between seasons, it is possible that Invincible may appear in “What If? Season 2” to team up with Spider-Man again! Do you think this crossover may happen?
Even then, it’s highly unlikely he’ll be able to reach a deal with Marvel. TV shows are a much bigger deal than one-off comics, so he won’t have the freedom to just throw Mark in there.
