"An Incident Under the Full Moon" (満月の出来ごと, Mangetsu no Dekigoto; Viz "Deeds Done by the Full Moon") is the two hundred eighth chapter of the Dragon Ball manga, and the fourteenth chapter of Part II of the manga.
Under the full moon, Piccolo meditates and the young Gohan sleeps. Waking up, Gohan goes to urinate over the side of the plateau, and seeing his shadow, happens to glance at the full moon, noting that he's never seen it before. The young half-Saiyan freezes up, before undergoing transforming into a giant monkey. Crushing his perch, the enraged Gohan begins to wreak havoc around the entire wasteland. Releasing several Kikōha from the Mouth, Gohan destroys his surroundings, causing Piccolo to remark on his destructive power.
Remembering Raditz's words about a Saiyan's full power, Piccolo looks up and sees the moon. With a powerful blast of ki, he destroys the lunar sphere, causing Gohan to revert to normal. Piccolo concludes that destroying the moon was the best idea, as if Gohan can cause as much damage as he did, fully grown Saiyans would only be stronger. After deciding the tail was more of a detriment than a help, Piccolo removed it from Gohan's body, and gave the boy new clothes modeled after Gokū's, as well as a sword. He then tells the sleeping boy that, after he returns from his training, he'll turn Gohan into a fine "Mazoku".
In the Afterworld, Son Gokū sleeps.
- Piccolo's choice of word for Gohan in this chapter, Mazoku (魔族, Demon clansmen), refers to his status as the Daimaō (大魔王, Great Demon King). Mazoku are the lowest rung of demon, typically ruled over by a Maō (魔王, Demon King), who are, in turn, ruled over by the Daimaō.
