I think S3/4 Shiro is a robot not a clone (bc his dainty fingers look like Galra robot hands) and Keith won’t kill him he’ll just get Pidge to reprogram him into “the most expensive sex toy ever” ....okay so maybe “think” wasn’t the right word... the first part of this ask is true though, those are my thoughts I mean.
Nope, no take backsy. Voltron is going to go from a kids show to XXX Robo-Shiro on Happy Keith action next season. The words have been spoken they will be true!
More seriously though, a robot is an interesting idea. The only reason I doubt it is because of his headaches. I could believe the Galra could make a ridiculously human robot that actually thought it was the original, but if they created something mechanically from the ground up like that, then nothing traumatic has been done to the brain that should be causing pain (brainwashed shiro would have headaches because of druid meddling, while clone shiro would have them from the forced memory download).
I do really like the idea of robot shiro sex toy for a fan fic though. Someone needs to write that. Even better, someone needs to write Keith using his new sex toy on real Shiro when he comes back. No way that boy wouldn’t appreciate watching two Shiro’s going at it.
