Vegeta and Bulma
at equal many DBZ couples started forced.
vegeta was an acesino almost as bad as frieza however vegeta and bulma did not marry immediately it was only after the years living in the land that they began to relate, to the point that vegeta was changed to a good person.
It should be noted that bulma helps vegeta in their workouts with their gravity machines and she support to vegeta get stronger and in response vegeta is closer to your family as trunks and bra, I can say that is the best couple so a lot that evolved over.
Krillin and 18
although 18 was not as bad as vegeta even she had some hatred on her part from the humans but thanks to the repeated efforts of Krillin to help her and her brother was that he changed his way of thinking and thanks to that they would begin to know bothmore and more until he would find peace at his side.
they have been seen training together and supporting each other in battle as in the TOP where they fought together against several opponents.
I would say that it is the second best pair given that its evolution was a bit lower.
Gohan and Videl
although many do not recognize it gohan and videl have much in common both and entered the world of martial arts because they carried the burden of being the children of the savior of the earth what led them to help people fighting crime, it is so that they began to know each other in school and in the training part was the fact that gohan was more a terricola that led him to be interested in that lifestyle
Trunks and Mai
Although I understand that many do not like this couple the only bad thing that I can find is it is morally bad seen with the fact that Mai is actually an older adult woman that bulma with the body of a young woman and that is not known if trunks know that or not ... but again is DB couples bizarre exist much bulma married with a alien than killed a her friends. outside of that trunks and mai also have much in common they fought together to save their world and help those in need in the resistance, support each other to move forward and not lose hope besides that they were the couple that had better moments in the series and like gohan and videl, trunks and mai sought to have a normal and peaceful life. what most admires trunks is the will of mai despite making a earthling
Bardock and Gine
I only place them in that position because they are less known, but because of the author's comments
Goku and Chichi
They only saw each other once when they were children and did not see until they were already adults where they got married so they could hardly be considered friends.
Goku committed himself without knowing what marriage was and then accepted it without taking that responsibility seriously.
They got married without knowing each other.
both have nothing in common.
Chichi forces Goku to change many times to be a better father model, although that should not be bad. She does not understand that Goku is not interested in having a job or giving up fights.
Goku is more a saiyan than human and much of his interests are far from what his wife wants
Goku spent more time of their marriage absent 2 of them were by own decision
-cell games
-epilogue
-training in general
the author admit to hate chichi.
and a long time has passed but that relationship does not change in any aspect unlike bulma and vegeta
ok I will listen to opinions if you agree or not with this
