Data Goku

Data Goku is Goku's memory of him being used to living on planet earth.







Dragon Ball:Stories
Because Goku is not from earth,data goku is only him turning back into a child again.

Data Goku was able to reach many gouls than the original Goku did and became super saiyn 5,super saiyn 6 and super saiyn 7. Data Goku is not Gohan or Goten's father at all for a reason.
