Dragon Ball Super: Season 4, Episode 23

4 - 23: Goku vs Arale! The Earth Comes to an End Due to their Battle?

Vegeta, Bulma, and Trunks attend a science competition that is hosted by Mr. Satan, with Goku hired for security. Dr. Senbei Norimaki of Penguin Village wins the award for his Reality Machine that conjures any item the user can think of. The ceremony is interrupted by the ghost of Dr. Norimaki's nemesis Dr. Mashirito, who used a chemical called Playtime-X to increase the hyperactive tendencies of Norimaki's powerful robot daughter Arale Norimaki to destructive levels. Vegeta attempts to stop Arale, but is sent flying after being overwhelmed by her strength and cartoon physics. Goku, recognizing Arale from when they met in his youth, transforms into Super Saiyan Blue with both equally matched. Bulma fears the fight could destroy the world, and uses the collective thoughts of the viewing audience with the Reality Machine to create a mass of delicious food. This attracts Beerus, who obliterates Dr. Mashirito when he interrupts the destroyer. Before he can do the same to Arale, the ingested food causes him severe stomach pain and prompts him to rush home with Whis. Shortly afterwards, Dr. Norimaki and Arale leave and return home, with Goku and Arale agreeing to fight again in the future.
