Dragon Ball Swallowing the Universe

Gretel: In this world, I am the only Saiyan legend, an everlasting myth! Vegeta, you are too weak! Are you worthy of being called the Prince of the Saiyans? Frieza, with this little strength, is he worthy of being called the Emperor of the Universe? Broly? Is this the power of the legendary Super Saiyan? I haven't even transformed into a Super Saiyan! So boring! Demon Puu? I heard you are very strong, let me give you a hand! Beerus woke up and said in horror: "Wes, I feel an extremely bad premonition!"
