Differences from the TV series

 * 1) All errors present in the TV episodes have been fixed.
 * 2) Many minor events are cut out from the movie to fit its two-hour timeslot. As a result, some exposition is lost.
 * 3) The first Ben 10 product to be released in Japan before anywhere else, despite being an American intellectual property.
 * 4) Khyber is now renamed "Kaiba", a Japanese word meaning "seahorse." Why? Because it's the exact same word as the Japanese transliteration of "Khyber." Also, in the Japanese script, his name is the only character name written in kanji while everyone else's names are written in katakana.
 * 5) Animalistic vocal effects are now sampled by real animals: dogs for Wildmutt and Zed, tigers for Rath, etc. Nemetrix predator vocal effects remain the same as the original English version.
 * 6) While the English cast remains exactly the same, the Japanese cast is completely different from the show's dub.
 * 7) All new music by Hiroyuki Sawano of Blue Exorcist and Attack on Titan fame. He even produced the ending credits theme song.
 * 8) All previous DVD releases of the franchise contained only an English stereo audio track with English closed captions. This film, however, had a bilingual release not only on DVD, but also on Blu-ray. Both the English and Japanese audio tracks are sampled in 5.1 surround sound, with the latter also having a stereo option. Subtitles include English closed captions and Japanese subtitles.
