- there is Saiyajin Kami and Super Saiyajin Kami seemingly, it's aura is more burning, flaming-like and the eyes and hair become red, there are different conditions for one to enter them than normal Saiyajin transformations,
- Mystic form is not part of the Saiyajin forms, though Gohan can still enter SSJ,
- Vegat surpasses Goku for a split second and quite likely will become the next Kami no Saiyajin in the next movie, or so he dibs
- looks like the stronger the father is, the easier it is for their kids to enter SSJ, seemingly Pan (though unnamed yet ?) enters SSJ in Videl's womb,
- it was confirmed that specials are canon (but OVA and other Movies are still non-canon), since this movie is canon and they mention Vegeta's brother in it,
- Akira didn't care that much about Dragon Ball along the Buu Sage (manga) and almost lost any interest when the DBZ anime ended; when asked to draw some of the old characters for this movie, he failed, was admonished and had to redo them... looks like if it wasn't for the second author supporting Toriyama, this movie might have ended pretty badly, lol
- the second author's initial concept for Kami no Saiyajin was more akin to SSJ4 (and SSJ5?), but Toriyama didn't like it, trashed it (lol, funny right ?) and they bickered a bit on how it was meant to look, until what it finally became... which seemingly looks very similar to the original SSJ design that one can see in one of the Movies with Lord Slug.
