Super Dragon Ball Heroes S04E02 - The Warrior in Black Appears! A New Adventure Starts!

Goku and Hearts struggle against the newly-empowered Frieza and Cooler, until their battle is interrupted by the arrival of the alternate Broly in his Legendary Super Saiyan form. Broly attacks all four combatants, overpowering them all, as the masked Saiyan looks on. Suddenly, a mysterious cloaked figure arrives on the scene and attacks both Cooler and Frieza, removing the Dark Dragon Balls from both of them. Broly attacks the cloaked figure, who leads him away. Hearts reveals that he is unable to read the minds of either the cloaked figure or the masked Saiyan, who teleports away. Hearts gives Goku a duplicate Senzu bean to heal his injuries, and reveals that duplicates of the normal Dragon Balls also exist in this universe. Goku theorizes that if they gather all of the duplicate Dragon Balls, they may be able to use them to escape. Using a duplicate of the Dragon Radar, they track one of the other Dragon Balls to a nearby planet. On that planet, the masked Saiyan observes Vegeta, Turles and Cumber, and orders them to begin fighting each other.
