The Return of the Beast: Part 1 - S1-E1
Trivia: When we see the flashback of the accident that caused Bruce Banner to become the Hulk, at first we see the Hulk colored gray and then slowly turn green. This is a reference to the comics, in which the Hulk was gray in his original appearance.
Trivia: The season one episodes "Doomed" and "Fantastic Fortitude" crossed over with the Fantastic Four series that was airing around the same time.
Answer: I believe it was mentioned in an issue of Wizard Magazine that the show was cancelled because of low ratings, and reportedly the show's creative shift in the second season had a part to play in the low ratings, as the changes alienated fans.
