Fanta, the C/FO mascot (and I believe the first named skiltaire to leave Sy's mind) piloting a mecha. [Z: Whoops! Theta was the first]
Wendell Washer——who was already a story director and storyboard artist for many cartoons and only kept going——1983

Granted, this is issue #22 of the little update bulletin, this is the oldest mention I've seen of "skiruteru" which
I'm sure was thrown around for fun very often in those meetings. スキルテルヤキ, anyone?

What a rabbit hole.. I've only ever seen かっこいい, but apparently there would be a space there. Bit like the first
time I saw "gomen nasai" written in romaji. And the kanji does give the long 'O' sound. Funny how words change over
time——I guess the word hasn't changed, but the way people write it on the internet.

Preserved by Confurence.com I believe, as most of Archive.org's were, presumably by Rod or Mark.

Funny enough, this is one of the very few pieces tagged "skiltaire" on e621, but this same bulletin had a few more on a
different page.
