From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
The Saiyan Hero is the main character of the Japanese arcade game Dragon Ball Heroes.
Hero's appearance is similar to that of Son Goku in Dragon Ball GT, but he is a little taller and has different hairstyle. His clothes are similar to Goten's in Dragon Ball Z: he has an undershirt that is yellow and goes to his wrists like Goten's blue undershirt. His torso and bottoms are both a crimson like red, and he wears a blue-aqua colored belt. His shoes are almost exactly like GT Goku's, but instead of the white ankle wraps Hero wears yellow. Hero seems to be part Saiyan.
- Hero learned the Kamehameha the first time he tried, just like Goku.
- His first major fight is against Cell.
- Hero looks alot like the character in the Hero mode trailers in Dragon Ball Z: Ultimate Tenkaichi, which may or may not be coincidental
