there's several Kingdom of Love- Ochaco scenarios that are my favorite
Femme Fatale - The evil hands hypnotize Ochaco into becoming a supervillainess to help in some schemes. Going so far as to put her in a new costume and inflate her to give her some hourglass proportions. However this scheme ends with Ochaco snapping out of the mind control and giving the evil hands a good whooping. Alternatively the attempt to give her an hourglass figure goes wrong as the evil hands now have to deal with an angry balloon who snapped out of their mind control
Ochako starts testing her Gravity Quirk by holding her breath so much her cheeks puff up then her whole body starts inflating, her suit get ripped until she uber inflated and massive, looming over the whole city.
She uses her power and reaches space where she inflates enormously. In the process, she encounters Mt. Lady (who is still there from the previous comic) and transfers all her air to her, leaving Ochako uber-inflated.
