@Vehrec, Leslie is a real person from TOS, whose name is canon. He was played by Eddie Paskey. He is not a composite. Everything I've mentioned happening to him, happened to him. Or happened to everyone aboard the
Enterprise (e.g. the time he got turned into a mineral-salt cuboctahedron).
See, the trick is that Paskey was a very, very regular extra on the show, so he showed up in dozens of episodes, not always doing the same job,
usually but not always in a red shirt.
The old guy whose face I've used a few times for Leslie? That is in fact the same guy- Eddie Paskey, only forty years later. He had a cameo in a fan production around, oh... 2005-2010 or so.
Here is his Memory Alpha page:
Leslie
And here is a Youtube tribute:
With two (arguably three) exceptions, the TOS-era exploits of his that I've referenced are canon, or something that could very plausibly have occurred off-screen immediately after or before one of his on-screen appearances, like him dislocating Richard Daystrom's shoulder during
The Ultimate Computer, or getting headbutted by a normal-forehead Klingon, which presumably happened while breaking up the barfight during
The Trouble With Tribbles.
The exceptions:
1) I attribute to him getting headbutted by a ridged-forehead Klingon at some unspecified time. This presumably happened after the TOS era.
2) The injuries he suffered during the course of
Operation: Annihilate!, and his consequent attempts to seek medical leave, are not canon. However, they correspond to (thankfully less serious) injuries that actually happened
to the actor who played him and did indeed force Paskey to leave the show in the middle of Season Three.
3) I attribute to him the rough draft of the lyrics from
Banned From Argo, notionally drafted during the events of
The Naked Time. Which I did only because the song is in real life written by
Leslie Fish, and because I needed an excuse for Leslie's career to have stalled for like twenty years.
EDIT: I DID (sort of) make up his first name, in that he doesn't have a first name in the show canon, and there are contradictory names on offer in the Expanded Universe canon. Of the ones available, I picked "Eddie" for the actor who plays him.
Oh, and there are a few things in some of the omakes which are actually references to Star Trek Online's
Agents of Yesterday campaign, not TOS proper, but that's not me making anything up
I really don't know what else there is to say about the subject.
It's not that I don't get the joke. I also got the joke based on Janeway's shuttle-spamming powers.
But this is a question that might actually matter to us in-game, so the discussion of it (including your joke) inspired me to actually go back and look up what happens, and it does look like on all three occasions that it was a plot point, they actually did have
Voyager go back and retrieve the warp core and refurbish it.
