I dreamt that the idea of sending multiple terminators back in time resulted in a final Hail Mary from Skynet that resulted in dozens more Terminators being sent back through time to much earlier in history. My dream focused around an early 30s black man in 1800s America along with an old man t-800. They had been there for a few years and the T800 is able to track waves before a quantum event (similar to dark fate) where they eliminate threats to the past.

I liked the dynamic in my dream a lot because it was a robot, who was slave to the future resistance fighter, in a time where they had to show the resistance fighter as a slave to the old man. When I woke up I couldn't stop the making about it and wanted to start fleshing it out more.

What other sorts of things would be cannon for a story like this?

T800 couldn't ride a horse (too heavy) but maybe lead a wagon team.

T800 would be great as a blacksmith.

Resistance fighter would be PISSED about slavery and racism as he really only knew humans v. robots.

Anything else?
