Dende is a Namekian from the village of Elder Moori. During the Freeza Saga, Son Gohan and Krillin save him from Dodoria. He gets his power unlocked by Elder Guru, giving him the power to heal. Dende assists the heroes from Earth in calling the Eternal Dragon Porunga in his Namekian tongue. He aids the warriors by healing them during the fight with Freeza, saving them from death and amplifying Vegeta's power. Once Freeza learned of this, he is killed by the tyrant.
After being revived by Shenron, he lives on New Namek until Son Goku teleports there during the Cell Saga to ask a Namekian to become the new Guardian of the Earth and revive the Dragon Balls. Dende accepts, and continues to serve as the Guardian throughout the rest of the series. He recreates Shenron and improves him, making the dragon able to give two wishes instead of just one.
