Diana

Diana  is a woman that Hulk saves from some muggers. After saving her, he takes her back to Wayne Manor, where he flirts with her. Much to his surprise, she flirts back and eventually seduces Hulk with her carefree spirit and her goddess-like beauty. When she's ready to leave and go home, she decides against it, and flirts with Hulk once again before having sex with Hulk.

She is played by mega-hottie actress Phoebe Tonkin.

History
Diana appears at a gas station, refueling her car when several men grab and attack her before trying to strangle her. Luckily for her, Hulk arrives and saves her, though Diana was badly hurt before he showed up. With no other choice in mind, the Gamma Giant carried Diana back to Wayne Manor, where Alfred begins to treat her injuries. As she slowly recovers, she spends time with Hulk, showing that she's a relentless flirt and a total tease.

Eventually, her wounds are fully healed and she is told by Alfred that she can go home. However, having grown attached to Hulk, she doesn't want to leave, so she flirts with him one last time, finally convincing Hulk to have passionate sex with her.
