Alternate versions

The ABC Family and Toon Disney broadcast premieres removed the 4-minute intro with Angela Anaconda before the 20th Century Fox logo sequence, and replaced the Fox Kids logo between the 20th logo sequence and the opening credit sequence with the Saban International logo. 20th Century Fox is owned by the News Corporation in which it and Haim Saban, in 2001, sold what Fox Family became ABC Family, including what Saban Entertainment became BVS Entertainment and what the Fox Kids International channels became Jetix in 2005, to the Walt Disney Company.

This movie is actually the first, second and third Japanese Digimon movies edited together as one. Japanese anime movies can often be under 60 minutes long, which is of course not marketable to American theaters. With these two movies on a similar theme, Fox Kids put them together.

In the Japanese version of the third segment of the movie, Willis (or Wallace) has nothing to do with the creation of Diaboromon, Yolei didn't have uncles that helped her and the others go to Colorado, and there was a subplot where Endigomon (Diaboromon) kidnapped the original DigiDestined (Chosen Children) and made them younger in order to find Willis. Also, Willis never appeared in the second segment, that was added in the US release only.

In the Japenese version of segment 1, there is no text or dialogue in the opening shot, while in the American version, the opening shot has the text "Highton View Terrace, Japan, 8 years ago" and Kari's introductory narration.

The Japanese version of segment 3 ends on a debatable note: the revived Kokomon plots to go back in time again, while dancing, and Willis is uneasy at this, while the American version ends on a more satisfying note: Kari narrates for the last time, Kokomon dances to "All Star" by Smash Mouth, and Willis finds him "tone deaf."
