"The Akumaito Beam" (アクマイト光線, Akumaitokōsen; Viz "The Beam of Evil"; Literally meaning "The Devilmite Beam") is the one hundred fourth chapter of Part I of the Dragon Ball manga.


Gokū tells Ackman that he does not look like a formidable opponent in his eyes, offending the demon. Ackman then charges at the young boy on Uranai Baba's orders, but is quickly outclassed by Gokū. Kulilin then comments on how the demon does not look to be intimidating, but Kame-Sennin informs him that the demon had won the Tenkaichi Budōkai twice. As Baba chastises Ackman, the demon informs both her and Gokū that he intends to use his true power.

Ackman proceeds to use his Akumaito Beam, which amplifies the evil in one's heart and causes the opponent to implode. Kame-Sennin and Baba both acknowledge that the demon was going too far in attempting to kill Gokū. However, the young boy is unaffected by the technique, revealing that Gokū possess a heart that contains no evil, much to the relief of the Dragon Team. Frustrated, Ackman summons a pitchfork and attacks the young boy, leading Gokū to kick the demon with an undetectable speed, winning the match and stunning both Kame-Sennin and Baba.
