- RoF = Forbidden and when they show up they are told to leave. Bulma acted childish toward Freeza, no one told her to leave.
- U6 vs U7 = Forbidden with 0 chance to prove themselves by training in the ROSAT.
- Future Trunks time line = Forbidden with again no chance to prove themselves.
- ToP = Forbidden and kept secret
- Broly = Forbidden and kept secret
- Moro = Forbidden and kept secret, although it was good that Goten and Trunks was pissed off at Gohan for keeping secrets.
Goten wanted to go to Whis with Goku to get Super strong, but Chi Chi didn't allow that. When Goten and Goku got away from Chi Chi, Chi Chi alerted Bulma to stop Goten. Chi Chi claimed there are no bad guy, however there was no bad guy in Future Android Saga and Future Goku Black Saga, but since Future Gohan and Future Goten were weak they were killed.
We don't watch Dragon Ball to see characters forbidden 100%, we see Dragon Ball for the action. Imagine if Gohan was 100% forbidden that would have been boring. Good thing in DBZ Chi Chi compromised, unlike her DBS self who 100% forbids everything. Too bad Chi Chi in DBS lost her Buu Saga character development.
Then there is the problem that Goten and Trunks doesn't age one bit, when Goku grew from each tournament. Compare Goku from 21st Martial Art Tournament to 22nd Martial Art Tournament and you see the growth.
Compare Goten from Buu Saga to Moro Chapter and there is no growth.
In EOZ Goku and Vegeta mentions Goten and Trunks got lazy due to the peace time on earth, but in DBS we see that isn't true at all. They were lied and kept secrets so they do not join any battle. We see that they want to train and battle, but they are not allowed.
Some may say that Goten and Trunks acts like brats or maybe their fusion, however there is a thing called character development. Every character in Dragon Ball got character development, why should they be the exception? Why should they be the only one to get forbidden, when other does stupid things and worse.
Goku stupidity got Future Trunks time line erased. Buu falling asleep in a test and making Beerus angry was stupid of him and not taking his fight seriously. Lets not forget Vegeta helping Cell by protecting him from Trunks and Buu by getting possessed on purpose and killing thousands to force Goku to fight him. Lets not forget Vegeta and Goku destroying the potara.
Here are all of Vegeta stupid things he has done, yet no one stops him from training and fighting:
- Making Freeza transform into his 2nd form, to decrease their chance of winning.
- Helping Cell by letting him get away on purpose and to make it worse protected Cell from getting killed by Future Trunks.
- Choosing to side with Cell over his son Future Trunks.
- Getting possessed by Babidi on purpose.
- Killing thousands of innocent people just to force Goku to battle him.
- Battling Goku knowing that is helping Buu revive.
- Destroying two times the Potara.
- Vegeta refusing to fight together to beat Freeza, which puts the planet at risk.
- Destroying the ROSAT two times.
