Yesterday’s Star Trek TOS warm-up sketch: LARPing Spock from “Errand of Mercy”!
 

This particular Star Trek TOS warm-up got a little out of hand… here is Lieutenant Nyota Uhura, modeling Starfleet uniform variations (covering both canon and my own head-canon)…

– Row 1-1: Standard TOS woman’s uniform.
– Row 1-5: Dr. Dehner wore a uniform along these lines in “Where No Man Has Gone Before”.
– Row 2-2: Standard Kelvin timeline woman’s uniform.
– Row 2-5: Standard TOS men’s uniform.
– Row 2-6: Something resembling Dr. McCoy’s short-sleeved variant from TOS.

Using those 5 uniforms as tentpoles, I filled in several more variations to complete the line-up. I imagine there are many other variations accommodating alien anatomy and customs (see previous), but these would cover most basic humanoids.
 

I feel like 23rd century Federation technology really could have done a little more for Fleet Captain Pike in “The Menagerie”, like maybe a fully mechanized exo-suit with built-in phaser, tricorder and communicator?
 

Today’s Star Trek TOS warm-up sketch is based on the Mego Neptunian action figure with gear based on the Mego role-play toys. This red-skirt is a shrewd security officer who has survived many a doomed away-mission. Her uniform is modified to accommodate her species’ distinct physiology.
 

Another Star Trek TOS warm up–one of those maroon pig-ape aliens from “The Cage” as a Starfleet science officer. Don’t tell him he looks like ALF, he hates hearing that!
 

I’m in a Star Trek TOS mood, so here’s a glamorous Salt Vampire who joined Starfleet and became a captain! A strategic genius specializing in stealth operations, highly decorated, but has a bad habit of licking the salt off of everyone’s margaritas at parties.
