Green Girl

Linda Park used to be a lawyer for a pharmaceutical company 'Abstracts'
They were secretly working on a biological weapon that they would have sold to the highest bidder
Linda found out and tried to tell it to public but the workers at 'Abstracts' kidnapped her and tried to drown her by throwing her in some vat of random chemicals,
Her skin turned green because of the chemicals and she received some strange abilities, she grew big and smashed the building into dust, she also exposed all the dirty secrets 'Abstracts' was hiding to the world
Later on she joined Hero Alliance Corporation where she took nickname Green Girl and also started to date a member Great White Shark.
She did not appear much, so much of her adventures are unknown.
She died in front of the protector squad member's eyes, after Dark-Matter blasted a beam right through her neck, killing her instantly. She was mourned by her boyfriend, Great White Shark, who quit his super career.
