...dead, is the answer to that question, in most cases
They all live stupidly dangerous lives
The exception is probably Jamie. Who will live to be a malevolent chain-smoking whisky-soaked 80 year old
Scotty's also fairly likely to make it. He'll still be aboard the Enterprise, of course. You couldn't pry him out of that engine room with a crowbar.
Todd is already more than ten thousand years old. It'll take more than the SGC to finish him off
This turned into "which of my characters will still be alive in 10 years" depressingly fast
Zeller might make it if he can avoid doing a Bev
But the rest of them? Yeah, probably dead
Mikasa, dead. She's already outlived 90% of her classmates.
Han? Literally already dead in canon
Tony, probably dead. He almost dies a lot
Silk, definitely dead. Spies don't get old, and he's not exactly going to retire. He's going to go right on refusing to acknowledge that he's getting old until he gets himself killed
Rocket, again, definitely dead. Dangerous lifestyle PLUS shorter life expectancy to begin with
Sirius, also already dead in canon
Eames? Eames might make it to ten years, I suppose.
In which case he's probably going to be alternating between dossing around Mombasa annoying Yusuf, and wandering the world annoying Arthur
Zelenka...yeah, the Pegasus Galaxy is definitely going to happen to him at some point
Which just leaves my OCs, Jean (already established that he's going to die of lung cancer in his 20s) and Danny (who's a wily SOB but he still plays with bombs for a living)
THIS MEME IS SO MUCH MORE DEPRESSING THAN I ANTICIPATED
Peter and Rocket starting barfights in the afterlife
Tony and Loki-- well actually, I suppose in our verse, Tony's still alive in ten years
For golden apple related reasons
PS I'm reading that thread where they both sort-of die now
He maintains it was a reasonable question under the circumstances
