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
Am I missing one?
They get SS2 in the time chamber. I think there’s 4 SS2s?
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
