Dragon Ball Super Season 1 Episode 9

Goku gathers the Dragon Balls together and summons Shenron, who is startled by Beerus’ presence. Shenron quickly explains that the Super Saiyan God is not a person, but it is a legendary transformation that only kindhearted Saiyans can achieve by fusing their power together. The Saiyans attempt to transform Goku, but they fail as they are one Saiyan short. Growing tired of waiting, Beerus starts preparing his attack to destroy the planet. Suddenly, Videl jumps in front of the Saiyans. She says that there is one more Saiyan who might be able to help them, who happens to be her and Gohan’s unborn child. The Saiyans and Videl attempt the transformation again and manage to transform Goku into the Super Saiyan God.
