Its still so jarring seeing Connie being serious, it almost felt like a different person... and then page nine was there to remind me she really didn't change that much at all lol
TBH that would make for a great gag character where every time they need a power up, they cut or style their hair.
This could be taken to the extreme so that by the time they are bald they go into super sayin mode to grow long flowing locks.
Come to think of it this is probably why One Punch Man is bald and so well developed as a character.
Long hair is apparently hard and time consuming to draw, and to keep doing it consistently... then you see the cut/tied up hair later in. It's probably a more common occurrence when you're both the author and the artist.
Please stop with the boy haircut after a heartbreak trope... you got no idea how much it takes to keep beautiful hair and how much it's not a symbol to just destroy it to make your female char show determination...
