Dragon Ball Super

Goku gathers the Dragon Balls together and summons Shenron, who is startled upon learning of Beerus' presence. Shenron quickly explains that the Super Saiyan God is a legendary transformation that results from a ritual where six kind hearted Saiyans infuse their power into another. The Saiyans attempt to transform Goku, but they fail as they are one Saiyan short. An impatient Beerus was about to destroy the planet when Videl offers to join the ritual while revealing to be pregnant with Gohan's unborn child. The Saiyans and Videl attempt the transformation again and manage to transform Goku into the Super Saiyan God.
