Dragon Ball Super Episode 42

Trouble at the Victory Celebration! Showdown at Last?! Monaka vs. Son Goku. With the tournament completed, Bulma decides to hold a celebration party at the Capsule Corporation. She also decides to invite Monaka. Bulma considers Monaka to be the real winner of the tournament. Beerus and Whis are opposed to Bulma's idea as they believe that Goku would want to fight Monaka if he were to attend. Ultimately, Monaka does attend. Beerus decides to tell everyone besides Goku about Monaka's secret. Monaka is not nearly as powerful as everyone believes him to be. Goten and Trunks suggest that Beerus disguise himself as Monaka and fight Goku in Monaka's place. Beerus agrees to the plan and disguises himself. Pu'ar also shape-shifts itself into Beerus to act as a decoy. Shortly afterwards, Goku and a disguised Beerus begin their fight. Following a brief clash, Whis interrupts the battle. Everyone carries on with the festivities.
