Not just appearance, quirk and backstories
Also, made a punnet square. There's a total possibility Todoroki could exist. Doubt it but, his parents are two real hair colors. White hair or platinum hair exists, and red hair with blue eyes obviously exist. It could happen :/.

Todomomo

Rei: short hair, she was going to be more serious but I thought it would be better for her to be goofy.

August: Satoru. His name was Satoru, he was going to go to an all boys school, and he could create living things (like Leon from Fairytail. Ice make bs that was living-) I changed it to August when I made Cherry Vanilla when I was twelve. (I had made all of these ocs in seventh grade so I had just turned twelve when I started watching bnha and shipping.) August was also gonna have purple eyes from August Sr. And then I gave him Heterochromia, but changed it to blue eyes.

Kirimina

Iro was asexual and didn't feel much for anyone.

Akane, she was supposed to look exactly like Mina but at the moment I'm trying to find a good look for her.

Miruhawks

Y'all know the year long story.

She was gonna have an unknown dad, floppy ears, same personality as her mom, and she was supposed to be friends with Amai.

Iidamei

She was supposed to be Psychotic. Now she's more like Chris McClain from Total Drama.

Kamijirou

Stormi was gonna be a singer instead of a hero, she was gonna have long hair, and she was gonna be like Jirou but an idiot. Changed it up a lot.

Riitsu was an afterthought but if I can remember I think he was gonna be a girl.

Dabi x Toga

He and August were supposed to look identical except their hair colors were different.

Nejitama

Amai: her mean girl ness was supposed to go to Okimi but I decided to have irony in an oc and who better than the daughter of precious one, and tam tam? And her name is Amai! Makes total sense! She was also gonna be more of a tease and less of a bitch. She was gonna date Osoro only but then Okuri showed up and said "hello bitches, if you like it then you should put a ring on it".

Phoenix: The yandere thing was actually made pretty recently. I didn't even think of Phoenix and Daenerys until AkanoKaguya522 talked about it in the first.

Mt.Kamui

Okuri was male and might go back to being Oakley. It really depends.

Ryushot

Megami was named Megami Aibi (Goddess Ivy) before I shortened it to Megami. Then she was gonna be a baby but decided to make her 17. She was gonna be a sociopath but that plan got ruined because of my drawings of her.

Daenerys: was gonna be less developed than Meg but ya see how that turned out. She was also gonna feel forgotten because Meg is Ryuko and Shinya's favorite (never said it but it's a bit obvious) since she was right after a really sad time. She was also supposed to look a lot like Ryuko, which stayed, but she was gonna have white hair and blue eyes (like Meg does) but I changed it when Ryuko's color scheme was confirmed (it's now blonde with blue eyes.)

HitoRei

Rosalind took me ten minutes.

I'm not joking- I looked at a HitoRei picture and decided I liked it, then I started making her personality. Only part that I had problems with was her name. Rosalind actually took a while to warm up to.

Tetsukendou

None

SetSero

I made these kids recently, then I deleted Uroko cuz I was lazy and didn't want him anymore-

Shintati

Riven was gonna be a bitch and the same age as everyone else. Shindou was gonna hate him a bit because he attended UA, then my headcanons happened and I realized that wouldn't make sense so I changed it.

Manami was supposed to be Amai- like their personalities were almost the same, Manami was just Regina George but with brown hair and freckles.

Shintati

Spencer had brothers, she was based off of Lydia Deetz, and she was gonna be a goth with blonde hair that faded to green.

Midotsu

Mizūmi didn't have glasses and her main personality was being Rei's girlfriend before I decided on trying to give her one instead of ignoring it.

Mariposa was gonna be outgoing and tomboyish like Rei is or how Mina is. Then I thought it would be cute to make her shy like Izuku.

Clover was gonna be a sociopath before I just decided to stop doing that and just make her a bit quiet.

Kacchako

Osoro was gonna be a big bitch and be Amai's co worker in ruining lives. He and Okimi were twins.

Okimi; she had a sister named Akemi. Akemi doesn't exist anymore. She was also supposed to be just like Mitsuki and Bakugo, then all of that got transferred to Baby Juno.
