Abo and his brother Kado were once soldiers who served Frieza, ranking in the same tier as the Ginyu Force, as Vegeta explains in hindsight. Two years after the defeat of Kid Buu, Vegeta's estranged brother Tarble, accompanied by his wife Gure, flee to Earth to seek Vegeta's assistance in defeating the brother duo, whom Tarble confesses have since become as powerful as Frieza and have been terrorizing a remote star which he calls home.
Abo and Kado pursue Tarble and Gure to Earth using Saiyan Pods, where Trunks and Goten are unleashed on the two. After struggles from both sides, Abo and Kado fuse into Aka, prompting Trunks and Goten to fuse into Gotenks and incite another battle. When Aka begins to demonstrate a significantly devastating power, Goku and Vegeta prepare to destroy him, however a trick Goku plays on Vegeta results in Goku successfully being the one to vanquish Aka.
During the closing sequence of the film, Abo and Kado join the Z Fighters and their friends at Mr. Satan's ruined banquet, where they are seen eating Chi-Chi's radishes.
