Ha ha a sketch! Cause that's as far as I went with this before kinda getting distracted by everything else and I'm gonna change things anyway so it's abandoned, sorry about that.

This is Armin's 2.0 form for that third Wolfriders of Malvia season, where he has since been decided upon being an Unarmed Ninja/Monk and being a red panda rather than a lemur. The design was more or less the same as the 1.0 version besides the species change, with some things made a little bigger and a little poofier both clothes-wise and build-wise (as Mustelids are more or less equivalent to dwarves sort of in this campaign).

That's also why he's short now! Originally he was gonna be just a standard sort of size, but NX-42's next character is a little rabbit cleric named Takis, who was going to be halfling size basically, so I thought it'd be cute and make sense to shorten Armin down to 4 and a half feet (as shown with the handy corner image there featuring Milo).

I can offer some other mild concepts that have been in my head about Armin, none of which is finalized or refined at all, but my general initial idea is that he's the son of a really overbearing noble family. He learns about an uncle that ran off, and runs off after him, getting him to teach him a bunch of stuff, like fighting, gambling, making it on your own, etc. Armin also will probably have a sibling that's enrolled in the military (who would potentially know Takis's sibling), and he'd also know how to play violin (or its equivalent) quite well, but would do so to his annoyance, as it was forced upon him as part of his upbringing.

Not much else without the proper setting and setup that won't be settled until well after this current campaign/season ends, and there's still plenty of that to do yet, so Armin's still on the backburner after all this time. Going to give him another redesign, make his design less plain/generic-ninja-y, stuff like that. All in the future!
