I guess it is based off Zenkai which is an ability exclusive only to Saiyans and Saiyan hybrids. When a Saiyan is wounded badly and near death but they recover from it, they gain a massive rise in their battle power. However to become the true Super Saiyan of the legend, one must face an extreme surge of emotion that rages from their heart.
