It's super cool (and kind of surreal) to see a DBZ reference in EGS. I had no idea that Dan was into it.
Also, regarding scouters, there's a little-known fact about them that the author, Akira Toriyama, has only mentioned at a few anime cons: they were designed to be shitty (by the author, not the in-universe creators). Their entire purpose was to give the bad guys a reason to underestimate the good guys.
When you get a chance to watch it, be sure to watch DBZ Kai. It's a condensed, slightly updated version of the anime, with all the filler taken out. For comparison, DBZ Kai tells the same story in 159 episodes that it took DBZ to tell in 291.
The reason for this is that the original anime was airing at the same time that the manga it was adapting was being written. When the anime caught up to the manga, it had to slow itself down to a crawl to avoid overtaking the manga and having nothing left to adapt. DBZ Kai takes out all the junk they added to slow the anime down.
