No need for very much explanation here. This video is the openings (and eyecatches) from the Japanese dub of the 90’s X-Men cartoon. The songs are “Rising” and “Dakishimetai Dare Yori Mo” by Ambience.
The animation here is so much better than in the actual episodes.
How did Cable get so prominent in the first opening? He was only in like three episodes. And the Brood were in less than that.
