Who will be the next person to get SSJGSSJ?

[Pyro]

Gotenks plz!!!

Unlikely, given how he was treated in BOG and wasn't even included in FnF.

 

[Son Gokū]

Have we not decided yet?
The possible choices are:
Gohan
Goten
Trunks
Gotenks
Pan

I think Gohan and Pan have higher chances than Goten or Trunks, which would also mean Gotenks...
IF Gohan decides carry on with the life he wants, I wouldn't mind that much. He should be able to do what he wants.
Hmm... that gives Pan the best edge.
And like I said before, she beat Goten, who beat Buu earlier that day...

It's been 2 years and none has reached the SSjinB form yet except Goku, Vegeta and Vegito who is a fusion BTW.
