Other universes are severally underused

Particularly u6 should have been an entire story arc. Vegeta and goku going to visit u6 planet salada would have been amazing. Seeing vegeta kneel to their king would be a big moment. Also u6 villain being broly, cooler, or baby would make a lot sense. Letting vegeta get the win this arc would be satisfying saving the saiyans when he couldn’t years ago.

The arc could be a vegeta focused arc or both vegeta and goku. If it’s both then a story like super hero makes more sense. Goku and Vegeta could be months away from earth letting gohan, piccolo, trunks, and goten defend the earth and possibly even get trained by whis.
