Super Dragon Ball Heroes: Season 1, Episode 3

1 - 3: The Mightiest Radiance! Vegito Blue Kaio-ken Explodes!

Just before Cumber can kill Future Trunks, Vegito transforms into Super Saiyan Blue and saves Future Trunks from the blast. When Cumber weakens Vegito, he transforms into Super Saiyan Blue Kaio-ken x20 and continues to fight Cumber while Cooler observes, noticing that the chains around the Prison Planet have begun to break due to Vegito and Cumber's fight. As Cumber prepares to fire a ki blast, Vegito attempts to counter it with a Final Kamehameha but fails. Cumber then creates an artificial moon and uses it to transform into a Golden Great Ape. In this transformation, Cumber attacks Vegito, who defuses back into Goku and Vegeta after using up too much energy. Goku and Vegeta then prepare to battle Cumber one last time.
