Pilaf was the Pilaf of the future Trunks's world.
Pilaf was short in height and has blue skin (green in some of Toriyama's artworks). As he got older, he lost teeth and his skin became more wrinkled. After wishing for his youth from Shenron, Pilaf was transformed into an infant and he wore feet pajamas and a bib. He also had a pacifier.
On May 12th, Age 767, the Pilaf Gang gathered the Dragon Balls, while the Androids were attacking the Dragon Team, and summoned Shenron. Pilaf wished for their youth, and Shenron granted their wish, making them become infants before the Dragon Balls became inactive due to Piccolo's death.
