When she is in effects of the virus she migth act normal sometime but she also gets really agressive when she gets too big, she could even destroy a city

Her transformation is pretty slow yet effective, and she can move even tho all of that muscle makes it hard to, her chest will also expand a lot, she migth be a little shy or extremely lustful and would do anything to spread the virus, but it depends on luck

An infected whos different from the others

Yui-chan is a shy, frail, but generous soul who is always willing to help others.

My favourite one from that one dating game lol

She was kind and bubbly...and used to be small, now shes a huge raging animal with little to no humanity from the inside

It was her idea...

Her name is Betty. She escaped from the foundation with her Red She-hulk alter ego. She was freezing outside until she turned and started desparetly finding a shelter. When shes not She-hulk, shes just a normal sized girl with long black hair, ligth skin and blue eyes, shes really kind. As She-hulk, she has yellow eyes. Shes extremly agressive and able to mostly break everything with no effort, but she can turn back easly if she gets what she wants (its like a different entity or personality)

Funny, clumsy, kind, super loyal, can grant any wish no mater how much (i guess), her lamp is like a literal apartment for her
