The 1st version of the alternate anime-style intros created for the Japanese broadcast of the early 90s X-Men cartoon.
People, its just a openning created by Japanese TV for the Fox/Saban's X-MEN Cartoon:
The original opening sequence featured the X-Men demonstrating their mutant abilities to the instrumental theme. This intro is used throughout the first four seasons. A modified version is eventually introduced in season 5, episode 5 (Longshot). In this new intro, the beginning of the theme is slightly changed. New fighting scenes are also added.
The credit sequence consisted of rotating 3D models of the different team-members set to the theme. When UPN began airing repeats on Sunday mornings an alternate credits sequence was used: instead, a montage of clips from the series was used.
Rede Globo cut all of the intro sequence except for the logo at its end -- which they do to almost all animated series they air. The American intro was retained when it was aired later on Fox Kids and Jetix.
The opening intro was replaced with a new, Japanese-animated segment of the characters as well as a new Japanese theme with vocals called "Rising (ライジング)", by the Japanese band Ambience (アンビエンス). Starting with episode 46 an alternate anime intro was used, featuring the new theme "Dakishimetai Dare Yori Mo (抱きしめたい誰よりも...)". The end credits sequence was also changed: it featured shots of X-Men comic books set to the song "Back To You (バック･トウ･ユー)", also by Ambience.
Several very well-known Seiyū (Japanese voice actors) played roles in the X-Men Japanese dub, such as Koichi Yamadera (Cyclops), Rihoko Yoshida (Storm), Akiko Hiramatsu (Jubilee), Masashi Ebara (Wolverine), Norio Wakamoto (Mr. Sinister) Ryūzaburō Ōtomo (Magneto) and Rokuro Naya (Professor X).
