"Explosive Birth!! Gotenks: Adult" (爆誕!! ゴテンクス：青年期 Bakutan!! Gotenkusu: Seinen-ki) is an extra chapter for Dragon Ball Heroes: Victory Mission.
Beat and Note are sent to investigate an evil ki, and find themselves face-to-face against the Black Smoke Dragon and an evil Goku! Not even Froze's appearance is enough to overcome his power, so they will need to rely on the new fusion of Goten: GT and Trunks: GT… Gotenks: Adult!
