The omnintrix can absorb aliens right? So i was wondering if he had the chance could he take Supes DNA and put it into the omnintrix and use superman? I know little about Ben so i don't know if he has limits to what he can turn into. And if he can do that can he turn into other aliens like Goku or something?
Technically it could happen since the Omnitrix can copy alien D.N.A it should be able to become any type of alien species as far as power goes it can vary. Remember Ben has trouble trying to figure out what each alien does he wont be as powerful as Superman though, due to how long Superman has been training and using his powers also the about of yellow solar energy Superman has absorbed over the years, the same can be said of Goku's race he can copy the D.N.A but ben lacks the combat experience and the training that Goku has so he wont be as powerful.
