Continuity mistake: This series is in the same continuity as the other Marvel animated series that aired around the same time - X-Men, Spider-Man, Iron Man, and The Incredible Hulk - by virtue of each aforementioned show crossing over with at least one of the others. This episode, which originally aired on November 4, 1995, features a cameo appearance by She-Hulk. However, Jennifer Walter's didn't become She-Hulk until the season 1 episode of The Incredible Hulk entitled "Doomed," which originally aired on November 3, 1996. We know "Doomed" takes place after this episode, because the later episode of this series, entitled Nightmare in Green, features a plot where Dr. Doom meets Hulk for the first time after discovering that he is also Bruce Banner, and attempts to use him to destroy the Fantastic Four, and "Doomed" showcases Dr. Doom once again trying to use the Hulk to suit his own ends.
