Dianne Bellamy was first seen in "Incredible Hulk" #315. Doc Samson had agreed to give her an exclusive on his process of seperating Bruce Banner and the Hulk. She and her crew recorded much of the process before SHIELD intervened. They prevented any transmission of these news "for security reasons". Dianne and her crew were kept isolated for a while. When the Hulk escaped, Dianne got permission to partner up with Samson in his quest to relocate his subject. She used her own camera and drove a two-seat helicopter, the other seat open for Samson. The duo were already on a first-name basis.
Dianne kept covering Hulk stories for a while but lost track of him during his "Mr. Fixit" phase. She returned in "Hulk Aftersmash", now tracking the Warbound.
