Re: Which character has changed the least in the new universe?

"Sparks" would usually have been a nickname for a radioman or wireless operator. (The "Sparky" always getting rung up by Radar in the MASH
TV series would have come by his handle the same way.)
In the old days, before she'd acquired a given name, we might have had "Sparks" Uhura.
