Kappa is a friend of The Sponge, and was trained under Goku Jr. He is what many call "the chick magnet," as many girls think he is hot.
He was born under a mutation, resulting in a few odd features; First, he is unusually tall for his age of 13. Second, he has one brown eye, and one green eye, and third, he has white hair. At the age of 10, he had grayer hair, and was still very tall.
While trained under Goku Jr., he developed different features. First, he cut his originally grown-out hair, and became more active.
He is, like The Sponge, he is serious at times; but also jokes around. He will make comments about how Sponge is too serious, and will play pranks on him.
Kappa was born on September 13, Age 849, in the West City Hospital, and weighed 11 ounces. He is a descendant of Trunks, which makes him calm and collected, while having strong powers. (However, being related to Vegeta, his anger will spark at moments.) At the age of 6, his father died from a rare lung disease.
