Alright, let's get started.

#1 Emilia

Self-explanatory I'm sure. Next we got....

#2: Rem

We all know how she falls for him despite distrusting him at first. Her trying to kill him or not is debatable but I think she'll be less suspicious of Baru in this one. And I'm gonna be changing the outfit she wears during the battle with the white whale so stay in tune for that.

And for #3:Mei Beifong

Yes, that's what I imagined the OC to look like. Except she's blind like Toph and doesn't have the scar over her left eye. She's the great granddaughter of Bolin and Obal which makes her the Great Granddaughter of Toph. In terms of Earthbending, she's a gradual prodigy just like Toph was.

(No seriously, Toph is goated. And so is Azula, she was so good at firebending that she perfected it to a blue flame, I believe she perfected the craft or just found a way to make the flames hotter to that point. But she probably just mastered it and soon perfected that craft. Which is why Subaru is also able to do it, since he is Azula's descendant. As I stated in his bio awhile back.)

And that's all unless ya'll want more then I can see what I can do. As long as you can give a good explanation of why it could work and whatnot.
