 * 1)  Marlo Chandler  - Marlo Chandler was an aerobics and swimming instructor and a love interest for the casino security enforcer "Mr. Fixit", in reality the Hulk, believed dead, and now living incognito, his true identity unknown to Marlo. She ended their relationship after seeing him brutally kill an enemy. They later reconciled after Hulk reached out to her in a rare display of emotion and their relationship was able to end in a more amicable way. (#347, 1988),She later became Rick Jones' girlfriend, the Hulk's perennial sidekick, and best friend to his alter ego, Bruce Banner. She met Rick while he was on a book tour promoting his memoir, Sidekick.

Shortly after this introduction, Marlo assured Betty that she had nothing to be jealous about as Bruce and Joe were two distinct people and Bruce had been unswervingly loyal to Betty, the psychiatrist Doc Samson managed to integrate the various personalities of the Hulk, resulting in a being that now possessed a permanent Hulk body with Bruce's face and intelligence.

When Betty expressed skepticism of a continued relationship with this new version of her husband, she moved in with Marlo, with whom she became best friends.
 * 1)  Nadia Dornova  - When the Home Base conspiracy was trying to capture Bruce Banner, Nadia agreed to help them in exchange for the release of her ex-hubsand Emil. She seduced Bruce, but was unable to turn him over, eventually confessing the plan to him. When Emil was released, he and the Hulk fought, resulting in Emil's defeat.(FA TIH #382, Jun. 1991)

Nadia's experience with Bruce led to her developing romantic feelings for him. As she got to know Bruce she saw him as a gentle, respectful man; the polar opposite of her abusive husband Emil. Bruce had reciprocated those feelings, although his attraction to Nadia was nascent as he had recently overcome the death of his wife, Betty.
