Some sparse points:
- there is the internet (even named as such) in the Dragon World now (page 11);
- I like how Trunks' characterisation is mostly consistent with how he's portrayed in the second episode of Dragon Ball GT (as seen in MistareFusion's recent dissection), he doesn't want to be a manager, he craves for adventure;
- it's interesting to note that Hedo's android is from an "Alpha" series, and we all know that the androids in the Super Hero movie are from the "Gamma" series, this leads me to think that there's going to be a "Beta" series somewhere inbetween, I wonder if they planned this logical naming progression in advance when they wrote the movie, or if it's only a happy coincidence;
- speaking of names, it looks like the students carry on the theme first seen in Z with Sharpner and Erasa, since we now got Kompas and Rulah. What's next, Penzil and Scizor? Wait, the latter is already a Pokémon, then again we did get a Caterpie in the afterlife tournament, so who knows;
- the helper bots at the bottom of page 29 kinda look like Zeno;
- I totally ship Trunks × Mai, by the way. Mai has been my favourite female character in all Dragon Ball since the very beginning.
