Hello!
So I am mega indecisive and decided I would asked the community for help instead :) I have several fan pets I decided I wanted to start working soon, but I know I need to set goals first!
I've listed what I was considering, but would love opinions on what you guys believe would be perfect colors/species for them. I am open to experiment pets as well for suggestions.
Assassin's Creed Yusuf Tazim absolutely no idea tbh here is his wiki if you are interested
Carnival Row Philostrate I thought maybe something brooding lol here is his wiki
Mad Max Rockatansky I was considering a storm archan at first, but I feel like it's too "wet" when he's stuck in a super dry world. I'm currently considering reborn telenine
Final Fantasy XV (Nyx Ulric) Kingsglaive for him, I was considering keeping what he's zapped at, but also a galactic mahar or reborn mahar. I kind of want a pet with horns just because I want to keep that aesthetic (the horn thingy on his shoulder).
Star Wars D-0 Maybe steamwork or something mechanical looking? hmm
Man, I want to help you, but I am not really a part of any of these fandoms...except Star Wars kinda. I see D-0 is a cute little robot with a pointy head, so I would suggest one of these:

The aenoid seems most like D-0's physical appearance, with a face that kind of sticks out and a body right underneath that. The priggle captures a kind of eager innocence that most robots in the Star Wars universe have. The rreign has a pointy face and wheels on its feet, which also mimics D-0's appearance. But I think I like the wyllop most of all: pointy face, big wheel, and eager/innocent facial features. Also, if I understand the wookiepedia correctly, D-0 once worked for the bad guys, and you could make a subtle reference to the fact that rats are often seen as the bad guys, but D-0 and rats are really good.
You could also do a sort of overlay of green and off-white to make whichever you choose look more like D-0.
Thank you so much! I absolutely love the wyllop because of the big wheel and the demeanor it gives off. Cool :)
I think Yusuf would suit a wyllop as well - they're quick, excellent climbers, nimble paws, they got that shaggy li'l bit of hair...
Cream is closest to his 'real' colour scheme. Darkmatter's got the best expression imo. Or Bloodred to highlight the assassin part.
[edit] Terracoon would work too, for the same sorts of reasons, though the facial expressions aren't as good. Blacklight, Reborn, Galactic maybe.
I'd go with Darkmatter Wyllop myself.
Thank you so much for the suggestions! You're right, cream does match his color scheme. I could purchase an overlay with the colors updated to that, so that's a good idea!
I do like the darkmatter wyllop's expression, but I am leaning towards the reborn terracoon because those kind of remind me of little thieves :p
