Sorry I don't have pictures for all of them yet!

She/her

I like to use her to represent myself
Oscar
He/him
Oscar is a grey lion who was forcibly experimented on when he was little. He had some of his organs replaced with the ones of a dead alien in order to test out what their functions were. As a result, he now has some powers such as flight, super strength, and nigh invulnerability (meaning he is essentially just more resilient than the average person). He is currently in college and is dating a german shepherd named Brandon.
Harbor
He/him
A white wolf/dog looking guy. He is a highly advancded robot originally created so his creator wouldn't have to get a job. He is incredibly joyus and loves everything. He is also clumsy and pretty stupid in a ignorant kind of way. He is aware that he is a robot, however he is unaware that others don't know he is a robot as he looks like a normal guy. He doesn't try to hide being one at all, yet will never mention it unless it happens to come up, leading to situations where he accidentally freaks out his coworkers by drinking oil or taking off his head.
Harvard
He/him
The genius who made Harbor. Fox with some dark accents on his ears, legs, and spots above his eyes. He was an up and coming inventor who got good grades in college, until he developed severe anxiety that forced him inside all day. He now lives as a shut in living off of his parent's income in an apartment that they paid for. That is, until they threatned to cut him off unless he got a job. And so in response, he decided to do the very normal thing and build a sentient robot that will work for him, accidentally ending up creating the most annoying stupidest guy in the world (in his opinion). His parent's are unaware of Harbor's existence.
Blank
He/him/they/them
Blank started as the imaginary friend of a little kid named Kyle. Over time, for some unknown reason, Blank became real. However, Kyle is still the only person who can see/hear Blank as he is the only one who believes that he exists. Blank can interact with the world but others can not see it. Once Kyle became a teenager, his parents started pushing him into threapy as they became concenred that he still believed in his imaginary friend. One day, Kyle got upset and yelled at Blank to go away, as he thought that he his life would be better without him. Blank left, never to be seen again until Kyle was well into college when Blank just happened to stumble upon him outside. Because Blank can only be seen or heard by those who believe he is real, he had gone years without interacting with anyone until he saw Kyle again...
Thread
She/her
Thread is a sea creature part cat hybrid animal. She looks like a cat, but has a fish tail and a fin on her back. She is also missing her front legs. She got caught in a discarded net and ended up stuck on the beach in it, until an old man found her and helped her. He took her in and made sure she was healthy, however she decided she wanted to stay. Over time, she learned the local language and became friends with some of the other kids. She sometimes struggles due to her not having any front arms, but she rarely lets that get the best of her.
