Do these 2 deserve their own proper arc and super saiyan? And would you ACTUALLY watch it?
People always complain that Dragon Ball is just the Goku and Vegeta show, but they also complain when the main characters are kids, like in the original series or Daima. Pan got some spotlight in GT and Super Hero, but she was mostly just there. Her biggest contribution in GT was helping Goku achieve SSJ4, which was important but could have been written differently without her. Meanwhile, Bulla does almost nothing—her only notable moment in the manga is fixing Trunks’ laptop.
Since they get so little screen time, why not give them an entire arc to develop their characters, make them more interesting, and actually give them a role in the story? Maybe they could be so powerful that they skip straight to SSJ2. But would fans even care to watch it?
