Dende (デンデ, Dende) is a Namekian child saved from Dodoria by Son Gohan and Krillin. He later gains the power to heal after having his power unlocked, which he uses to aid the warriors fighting Frieza until he is killed by the tyrant. After being revived, he lives on New Namek until he is asked by Goku to replace Kami as Earth's guardian and revive the Dragon Balls. He accepts and continues to serve as the guardian throughout the rest of the series. He is very close to Piccolo, who fused with his friend Nail on Namek. He is voiced by Tomiko Suzuki in Japan and Ceyli Delgadillo, Laura Bailey and Justin Cook in the Funimation dub.
