UMMM OK OK THIS IS A LITTLE DIFFICULT WITHOUT ANYTHING TO GO OFF OF SO I'LL GIVE THE BASICS these aren't all of them but these are like. the most important ones
ok so first a good chunk of my ocs are a species called crizlyn from a planet named geocantra, they're basically just. guys made of crystals. that look like sonic people. the gemstones they're made of determine their powers

milne - main character i guess?? 26 year old amethyst crizlyn in the form of a cross fox, her natural power is super strength and she used to be a space pirate before she was kidnapped and experimented on by her planet's government (basically distorting her body to be sharp and jagged and giving her crystal manipulation/creation powers), escaped, and is now stranded on earth. she's not a very good role model at all, she gets into fights often, drinks (and smokes after learning that cigarettes on earth don't harm crizlyns at all), has no filter whatsoever and even if she isn't a pirate anymore she's still a petty thief.

iclyn - 13 year old kyanite crizlyn in the form of an akita inu dog, and the self-proclaimed best ice skater in the galaxy. her natural power is ice, and reworking how she met milne so i don't really have an explanation for how that happened rn but she's basically helping her get around on earth and in return milne is helping her learn how to use her ice powers. also she doesn't actually wear ice skates, she wears snow boots with skates MADE of ice. she's EXTREMELY annoying. she talks loudly and the only thing she usually does talk about is herself. she overestimates her own abilities causing her to get in bad situations very easily, which is ironic because she's actually insanely powerful for a crizlyn her age, she's just unable to use her powers properly.

randellia - 23 year old jade crizlyn in the form of a white-tailed deer, her natural power is plant manipulation. she's part of a small village of crizlyns that moved to earth due to discomfort with geocantra's government. she was the first person to meet milne after she crashed on earth and took her in for a bit (but she kicked her out because she's awful to live with. she still lets milne come over but she is NOT living with her). she has her own garden where she grows herbs and teas to sell in her village's market and has also practiced archery since she was little. she's not very good at talking to people and comes off as cold and annoyed to most people, but she's quite nice in reality. most jokes go right over her head

zinc - 24 year old porcupine, makes shitty robots out of old parts he finds while dumpster diving. his favorites are built out of eggman tech with the exception of bolt, the one robot he built entirely himself (he's just a little guy. fits in your hands and has big googly eyes). he used to live with his uncle iron before he passed, but now he lives with his uncle's friend handy hare. he's basically like an evil scientist but with robots, even with the cackling. he rarely takes off his gloves and goggles for sensory reasons. milne and iclyn live in handy's house with him and in return milne works at handy's car repair shop. zinc doesn't trust either of the two around his stuff

I HAVE MORE CHARACTERS but they're either extremely undeveloped or not as important

or both.

also milne and randellia are gay for each other and iclyn is the dog that goes "i know what you are"

milne & randellia - milne crashes nearby her village, randellia takes her in for a bit then kicks her out later because she's an awful roommate
milne & iclyn - idfk. i want to change it because the current reason makes no fucking sense, i think iclyn should be stuck on earth too maybe but idk
milne & zinc - milne finds a job at handy's mechanic shop, they realize she doesn't have anywhere to live so let her stay with them for the time being
iclyn & zinc - iclyn is dragged with milne
iclyn & randellia - no idea
zinc & randellia - no idea

milne and randellia.. sort of get along at first. randi is kind of annoyed by milne but there's no real hostility between them. after milne is kicked out randellia allows milne to visit whenever since their village is a sort of safe space for crizlyns that want to get away from geocantra but she does NOT want to LIVE with milne at the time. now they're having gay se i mean i wouldn't say they're fully in a relationship in canon but they're definitely both interested in each other

milne and iclyn, when they first meet iclyn is basically just milne's guide dog. milne has no clue about how anything on earth works and is a little annoyed and embarrassed about needing a child to help her get around. it sure does feed iclyn's ego though
later on, after milne opens up a little, they learn more about each other and both milne and randellia help iclyn learn more about how to use her abilities, the two of them are basically sisters. mother and daughter? whatever. they're like family.

randellia was very awkward around iclyn, she knows she's not good with kids and iclyn is far too energetic and full of herself for her liking. iclyn learns to behave herself a little more though and randi gets used to her noise. iclyn still likes to mess around with randellia often, but they're good friends

zinc is a little skeptic about milne and iclyn at first and doesn't like having other people in his space, but gets more friendly as time goes on. they still annoy him, but they're all friends. randellia and zinc don't really know each other well, though. they see each other in passing but thats about it
