When Dragonball first came on there wasn't really anyone with powers.They could just jump high,run fast, and fight really fast and good.Eventually Master Roshi created the Kamahamaha.That was the first supernatural thing that happend on the show.After a while they started learning a couple more attacks,not many.When Dragon Ball Z came on that's when they started learning alot more attacks.Dragon Ball Z is also when more charecters came in.
