Dragon Ball Manga Vol.9 Chapter 104: The Beam Of Evil

   

 Summary

Gokū tells Ackman that in his eyes, he doesn't look like a formidable opponent, insulting the demon. Ackman then attacks the young boy on Uranai Baba's orders, but is quickly overpowered by Goku. Kulilin then comments on how the demon doesn't look intimidating, but Kame-Sennin informs him that the demon has won the Tenkaichi Budōkai twice. As Baba reprimands Ackman, the demon informs both her and Gokū that he intends to use his true power.
Ackman proceeds to use his Akumaite Beam, which amplifies the evil in one's heart and causes the opponent to implode. Both Kame-Sennin and Baba acknowledge that the demon went too far in trying to kill Goku. However, the young boy is unaffected by the technique, revealing that Gokū has a heart that contains no evil, much to the Dragon Team's relief. Frustrated, Ackman summons a pitchfork and attacks the young boy, leading Gokū to kick the demon at an undetectable speed, winning the match and stunning both Kame-Sennin and Baba.
