The Incredible Hulk is an American animated television series starring the Marvel Comics character the Hulk. It ran two seasons, for 21 episodes, on the television network UPN from 1996 to 1997. Lou Ferrigno, who portrayed Universal's version of the Hulk on the live-action TV series from 1978 to 1982, provided the Hulk's voice. The show often featured cameo appearances by characters from other Marvel cartoons of the period. In the second season, the show's format, after UPN decided that season one was too dark, was changed, and to give "female viewers a chance", the network ordered that She-Hulk be made a regular co-star. As a result, the series was officially renamed The Incredible Hulk and She-Hulk. The second season also featured the Grey Hulk.
