Bio:

Mecha Goku is a robotic duplicate of Goku, created by Bulma as a training partner for Vegeta to use, Mecha Gokus are Android Saiyans (basically a man made saiyan) as such they have access to not only Goku's moves but also the moves of Androids (specifically Android 16) the Mecha Gokus lack the ability to ascend higher than ssj but make up for it by fighting in groups (its unknown how many there are but there are definitely enough to satisfy Vegeta) these Mecha Goku are also adaptable so they don't become predictable and keep whoever is using them on their toes.

Super Mecha: this is the equivalent of ssj, the body turn gold and the hair spikes up like normal ssj Goku (power equal to ssj Goku unless adjusted)

Moves:

Rocket Punch

Kamehameha
