Lots of initials in that title, right?!
The MCU Guardians of the Galaxy decide to head to Earth to see Peter's home. Sadly, they inadvertently go through a wormhole that takes them to an alternate Earth - the Walking Dead universe Earth from the TV series.
They arrive in Missouri at the most current point in the TV series with the following roster: Star-Lord, Gamora, Rocket, Groot, Drax, Nebula and Mantis. They all survive unscathed, but their ship is damaged beyond repair. They're stuck.
Scenarios:
1) They immediately seek out friendly assistance and go about fixing the world in whatever way they see fit (whether that be attempting to cure the virus, killing all zombies, keeping people safe or a combination of all three. Whatever you think they're capable of and whatever you believe would be most in-character).
2) The world immediately sees them as a threat, perhaps even identifying them as the reason the virus spread ("they're from space, they brought the virus with them!"). Word quickly spreads (don't worry about how) and the entire world is against them. Zombies and humans alike want them dead, with all humans seeing them as a common enemy and joining forces.
What happens in each of those scenarios?
