Shortly after Beers and Whis depart Earth, the God of Destruction of the 6th Universe, Gin, finds out what has happened between Beers and Goku, and sends his servant Tonic to Earth to investigate Earths warriors and test their power. Upon arriving on Earth, Tonic begins to wreak havoc in Satan City in order to draw out Goku and the others and is successful. With Kuririn and Piccolo watching in the background, Vegeta and Goku engage Tonic in battle. In between attacks, Goku inquires who Tonic is and what he wants, and Tonic tells Goku that he is on Earth because Beers failed to perform his duty as a God of Destruction. Goku assumes Tonic must be one of the other Gods of Destruction that Beers mentioned because he can't sense his ki. The battle is almost evenly matched, until the other saiyans arrive on the scene and help Vegeta become SSJG. Tonic is soon over powered by the two SSJG's, and barely escapes with his life. Before retreating, Tonic reveals that while he is indeed a God, he isn't a real God of Destruction, and that when his master Gin, the God of Destruction of the 6th universe, finds out how he has been treated, he will not be pleased.
Gin, having watched the entire battle from his realm with Rum, the God of Destruction of the 5th Universe (his servant is named Coke
), comments to Rum that at full power Tonic is much weaker than Beers, which means Beers should have been able to defeat Goku and have enough power left to destroy Earth. Gin believes Beers has become soft, and says that someone is going to have to take over for him. Rum says that it is Gins responsibility, since Beers is Gins brother. Gin says it is decided then, and after a short nap he will depart for Earth to finish the job for Beers.
Beers wakes up from his 3 year nap, finds out what has happened, and warns Goku that Gin will be arriving on Earth soon. Beers is determined to protect the Earth, which he believes only he can rightfully destroy. Goku, Beers, and Vegeta train in preparation for the battle to come.
Gin and Tonic arrive on Earth and confront Beers. Beers tells Gin that he will never let him destroy Earth, because only he can rightfully destroy it, and besides he can't let Earth be destroyed before he gets his custard pudding, and tries all of Earths other foods. Battle ensues between Gin and Beers, with Goku and Vegeta fighting against Tonic who has now become considerably stronger. The fight is eventually interrupted by Whis, who Beers and Gin are terrified of when he becomes angry. Whis reminds them that the tournament of the Gods will soon be upon them, and if they knock each other unconscious and are unable to participate, they will lose their titles as Gods of Destruction by default. Whis tells Gin that if he feels Beers is not suitable to do his job, he should consider having his servant Tonic challenge him in the Tournament of Gods. Gin sheepishly concedes that Whis is correct, and leaves Earth with Tonic.
Afterwards, Goku and Vegeta ask Beers to explain the tournament of the Gods, and who Gin is. Beers tells them that when Gods like him and Gin are born, they are assigned to attendants like Whis who are in charge of educating them and teaching them martial arts. He explains that Gin is his brother, and that they were both assigned to Whis and have been in competition their whole lives. As young Gods mature, Beers explains, they eventually enter into a Tournament of Gods which determines whether or not they will be placed in charge of a universe and be given the title "God of Destruction". One of these tournaments is about to begin, and the other Gods of Destruction and himself will be challenged for their titles. The idea of there being many more guys as strong as Beers and Gin, or possibly even stronger, excites Goku and Vegeta, and they are determined to somehow enter the tournament as well. Beers says that he has had enough talking, and that it's time to eat!
