this'll probably sound sorta dumb but here we go
for my robot oc whose design i showed on that one page i was thinking of a story along the rough lines of:
somewhere in the unspecified future, in a communist regime of some sorts, a line of swift, agile fighting robots is the military standard
this particular one was assigned into a security group guarding a research team which is conducting some secret black-mesa like experiment
the experiment goes to stuff and the robot dude here, among others, is zapped into a random time period, him in particular ending up in our times, crashing through a gate barrier and having his gun just flung into a nearby river
his Unknown Area Survival and Situational Preservation Protocols activate, which basically consist of "survive, don't get captured, try not to forget around with stuff"
he picks up the gate barrier and his knife from the ground, skadoodles the forget out into the wilderness nearby, whips up a makeshift spear and tries he best to survive without getting located, looking for a way back to the future
