^ no, it was an actual episode. Gonna drive me nuts but I'm not sure how to figure it out without watching the whole series.
You're probably thinking of the last 7-10 episodes. Those episodes were still being handled by Saban, but all the other companies had shut down by that point, so all new character designs had to be drawn up. Unforutnately, those are also some of the weakest episodes of the series (any one even care to comment on
Jubilee's Fairy Tale???),
Otherwise, I still consider this X-Men series to be the best of the shows, and when I want to watch an X-Men TV series, this is the one that I pull out the most.
Unfortunately, it's to bad that Disney decided to release the series in airing order, instead of production order, so you get
No Mutant Is An Island popping up in Season 5, when it should've gone into Season 3 (it should've been the first episode on the Volume 3 Disc 1 DVD). Also with the DVD's it's too bad that Disney didn't put on, either as bonuses, or just as different episodes, the remade versions of
No Mutant Is An Island, A Deal With The Devil, & Longshot, as the versions used are the original versions that were either missing graphics, or in the case of Island, completely rejected by FOX for animation issues (although the remade versions are on the Marvel website, plus, as far as anyone is aware, the remade versions were never aired outside the US---even Canada never saw them on broadcast TV, all we got were the original versions).
But it should also be noted that the 90's X-Men series crossed over with the 94 Spider-Man series a few times. One of those crossovers has been released on DVD in Canada as the "Mutant Agenda" DVD from Morningstar. Although, compared to the Disney DVD's, Morningstar's release is of lower quality, since it was a transfer of the old 1997 Telegenic VHS release, so it is VHS quality. The 2nd X-Men crossover was in the
Secret Wars arc in the final season of Spider-Man, but it's only Storm, as Storm's original voice actress was living in California at the time, so they didn't have to fly the whole X-Men cast down to California from Toronto. (
Secret Wars was released on VHS by Telegenic back in 1997, but so far there has been no NTSC DVD release.)
