I'll Be There For You (Like I've Been There For You)

When Howard Stark dies, his five remaining sons and daughters reunite for his funeral, one having vanished and one being dead. It's a bittersweet, mostly bitter reunion. But when their missing brother appears, babbling about an apocalypse, the Starks must figure out how to get over their trauma and band together in order to stop it.

Or: Steve, with super strength and ape-like body, spent his life trying to impress Howard, and was banished to the moon. Tony, controlling metal, especially attuned a suit he built, is a dropout from police academy and working at a fight ring for a room, Natasha is in a custody battle with her husband over her daughter (who she was using her rumoring powers on), Stephen, teleporter and time traveller, just wants a cup of coffee and to save the world, Wanda just wants to be noticed by her siblings, Peter is debating over sobriety and making the desecrated ghosts disappear and Bruce, well the ghost of Bruce at least, is just trying to keep Peter alive and sober while keeping the ghostly Hulk under wraps.

Or: The Umbrella Academy AU that no one wanted but I wrote anyway
