Todomomo

Rei can throw hands and can run pretty fast
August can't fight at all and after a few minutes of running HES out of breath
The twins are very active
Eve can lift weights at only a few months old.

Kirimina

Both are pretty athletic, Iro is on the basketball team tho.

Miruhawks

Dove is quite in between. She can lift a few heavy things but not a lot. The stuff is heavy in the workshop so she has to ask PowerLoader to
Get stuff for her sometimes. But she's still Miruko and Hawks's child so she is pretty fast.

Iidamei

Just like for Dove, the equipment is quite heavy. She has to be muscular to get the heavy things.

Kamijirou

Stormi is quite strong but she's kinda slow.

Riitsu is kind of frail. But he's fast af boi.

Dabi x Toga

Roman was raised by the League-

He's like a track star and a football player-

He can throw down-

Nejitama

Amai isn't muscular but she's quite fast and has a good slap. She feels a bit self conscious about being fragile and she's kinda mean when people call her cute.

Phoenix is strong for an eleven year old. With his quirk, he can fly and hurt people, so without his quirk he trained just so he didn't have to rely on his quirk in situations all the time.

Mt.Kamui

She's fragile af. Her quirk hardens her skin into bark and she becomes larger so she never really tried to get stronger. She's quite slow as well.

Ryushot

Megami is really frail. So she's not muscular at all, and she's quite fast, but not as fast as most of the other kids.

Daenerys is a Volleyball player. She's fast and strong.

HitoRei

Drama queen Rosa isn't muscular at all because her quirk lets her lift heavy stuff. She is fast tho.
