Dragon Ball: Odyssey

"Arthagas was the Prodigal Son. Sent to the planet Erde Tyrene to conquer it, a miscalculation of his landing caused him to lose all memory. He became Erde Tyrene's champion, married and had children. After a long period of time, a new generation of Saiyans came to conquer the planet. Arthagas led the resistance, first engaging his enemy, and then searching for his planet's Dragon Balls, to the final battle on Planet Vegeta itself, where he died. However, it is to be noted that he achieved the Super Saiyan 4 form before death..."
