White Tiger

White Tiger (real name Ava Ayala) is a S.H.I.E.L.D. trainee and the current successor in her family's legacy to bear the name. Originally a lone hero, she joined S.H.I.E.L.D. in an effort to become a right-hand woman to Nick Fury. With the rest of her group, she embarked on many missions and developed further as a hero. Throughout her time with the rest of the group, she rediscovered her hatred for Kraven the Hunter for the murders of her father and grandfather and overcame her desire to kill him herself with the aid of Spider-Man. She controls herself naturally and helps the others with that too.
