What about Videl? How do you personally think she would act?
given the context how gohan and all the other men are gone she would probably have been very sad at first and broken down.
At this point in time even at the beginning of super she has stopped training she doesn't fight any more and takes after ChiChi more than she used to and is very much a background character. As far as how to get her to be involved that is difficult the writers for super basically made her 2 dimensional in personality but building off her past. Videl and 18 would probably be the two fighting women to have gone after the dragon balls or help. Neither of them would cheat on their husbands without proof they are dead and not coming back or mind control Videl would probably adopt a costume like she wore as the great sayawoman and 18 would probably have trained her due to lack of anyone else that had even a basic understanding of marital arts to be stronger. As for handicaps bulma may have helped with special armor perhaps vegeta's gravity trainer and simulator to get Videl and 18 stronger perhaps even the dragon of earth would be used to get her stronger he grants 2 wishes. But she would be laser focused on bringing gohan home and 18 would be focused on bringing krillan home probably angry and in a bad mood he got captured to begin with and saying something to the effect of she is going to retrain him from the ground up.
Chi Chi with a wish from the earth dragon to be young might fight she was a decent fighter in dragon ball and pushed goten hard enough in training to make him go super sayian. She would be focused on gohan and goten believing goku can take care of himself when he gets hungry he will be home.
Yamcha still stronger than 90% of the human race he would get taken before random weak fighters. To get him in that situation humm he may be in cahoots with towa after bulma for himself
