There 10 characters in universe 6, however, they are presented as Dark Shadows. If you go back a few pages you'll see an image that I've uploaded, I highlighted the two shadow figures behind hit.
Yeah, I re-watched again. I saw two Dark Shadows behind Hit. Should be interesting.
I've got a feeling Caulifla's going down hard to trigger Kale's berserker power, especially with how overconfident she seems.
Frieza I believe is already becoming a huge asset to U7. I think he's going to use Frost to finalize a kind of alliance with U6 (and possibly even more), and then betray the crap out of Frost.
I bet Jiren just won't bother with Goku until he proves himself by sticking around long enough. Goku will try to fight him and have to come back later for one reason or another. Or maybe Goku will go against his urges and just ignore Jiren for a bit.
