Proto!deku - Blog Posts

I had this doodle lost in my carpets and I FORGOT ABOUT IT. But here you have, how the boys call each other on the FamilyAU where Deku and Yami are close cousins and Kacchan and proto!Katsu are identical twins.

So, let me explain! Proto!Katsu’s name on the AU is Katsuo (it means something really similar to the name Katsuki so, I think it’s perf!) and of course Deku would call him “Katsunii” because he would act like a big bro for him for sure. Kacchan will still be his precious Kacchan, while he calls “Mikkun” like a shortname to Yami since he was little, because his real name is Mikumo. He thinks it’s cute.

Yami couldn’t stand Kacchan personality at all, so he’d go with simply “Bakugou”. He’d call Deku and Katsu by his names because he’d feel himself being really close to them, just he wouldn’t be the kind to use nicknames.

Kacchan, well, he’d come to the same conclusion about Deku’s given nickname, and he definitely calls Yami by the nickname his brother gave him (when he’s not calling him weird names like gloomy face, that happens a lot). And Katsuo would be “Aniki” of course, exept when Kacchan is being the younger twin and calls him by his name, then Katsuo cries.

And finally, Katsuo’d call cute names to the cute Deku, “Izukkun” being his fave one because he’d spoil him a lot (That makes Kacchan angry 100% of the time) and Yamikumo would be his gloomy Yami and that would never change. Also, he calls his brother “Aniki” too, but he’d tease calling him cute nicknames just ‘cause he’s the older twin. He’d just call him by his name when with their parents and in serious situations, because they’d happen to fight a lot.

Aaaand that’s all~ ♥
