Goku Jr. (Scorpionic)

Son Goku Jr. is the great great grandson of Pan. He is a descendant of Goku, whom he looks very much like.

Bio
Son Goku Jr. was born in North City. He did not have the Son family name until Pan adopted him (humans in Dragon Ball usually have no family names). His mother was Chabata, the great granddaughter of Pan, and his father was Acon. However, Acon left while Chabata was still pregnant with Goku Jr.

When Goku Jr was born, Pan was present at the hospital and was visiting Chabata. He was named Goku Jr due to his resemblance to his ancestor.

When Goku Jr was a few months old, an earthquake happened in North City. Chabata and many relatives of Pan lived in North City. They all died in an earthquake, orphaning Goku Jr. Pan adopted him, taking him to Satan City, where he would be raised. The Dragon Balls were not used to reverse the tragedy, considering the events of the Shadow Dragon Saga.
