Is there a major arc in dragon ball (z and onwards) with no new forms introduced?
Just occurred to me that there might not be one
Saiyan saga has kaioken which isn't technically a form but may as well be
Frieza saga has super Saiyan, cell saga has super Saiyan grades and super Saiyan 2, buu has super Saiyan 3, bog has god, then blue, blue evolved and ui
No, except for maybe the Trunks from the future arch, super sayian 2 was kinda new at the moment, but still already seen on the main series. (edit, I think on that arch Trunks doesn't get SS 2 but SS1. I don't remember well)
Dragon Ball has the curse of needed to introduce new forms and raise the power level in order to continue the story.
In cell arc only gohan achieves ssj2 and it’s while fighting perfect cell after he kills android 16.
In hyperbolic time chamber gohan and goku perfect the ssj form so it doesn’t use as much energy or not more than base form.
Trunks “discovers” buff ssj1 form that is stronger but slower
