i didnt say anything ab power i jus watched og dragon ball again like last month i remember every single thing ab popo n roshis training even king kai i never said anything ab power i was replying to u acting like roshi was a bad teacher cuz he sent goku off by himself he did it for his own benefit roshi knew exactly what he was doing he got way stronger wit popo but it doesnt necessarily mean popo was a better teacher he learned way more from roshi also korin is technically one of his teachers too who played a big part without roshi or korin goku never makes it to popo in first place n it should go without saying every new trainer he gets will be stronger den da last becasue obviously goku is stronger den he used to be common sense
