While Kid Goku is happy to see them again, Pan reveals she was hoping they wouldn't run into the Saiya Squad again. Kid Trunks almost slips and calls Great Saiyaman by his real name Gohan, though manages to stop himself and calls the duo Saiyaman and Saiyawoman before asking what they are doing at Baba's Palace. Great Saiyaman reveals the Saiya Squad had come across a group of no-good villains in the area that have wreaking the place. Saiyawoman adds that they had just got done taking care of the villains, causing Goku to congratulate them. However Great Saiyaman states that one of them got away and Saiyawoman suggests Tekka's Team help them out and track him down as a form of training. Tekka agrees and Great Saiyaman reveals the villain that escaped is an Offworlder martial artist named Yamma (who also attacks Gine as part of team lead by Rubee in Sub-Event: "An Unlikely Pair"). Great Saiyaman tells them to be careful as Yamma is powerful, but Goten states it will be a piece of cake and to leave it to them, but slips up and calls him Gohan, revealing Great Saiyaman's identity to Pan, causing Videl and Gohan to yell at Goten, before dropping the subject and leaving the team to track down Yamma. The team finds Yamma standing under some mushrooms in the desert on the island below Fortuneteller Baba's Palace. Yamma is admonishing himself for almost getting caught by the Saiya Squad who he calls goofballs. Kid Trunks confronts him and Yamma asks who they are. Pan states they have heard that he has been up to no good and that they are taking him in to the Saiya Squad, though Yamma refuses to go quietly as he believes he can defeat them. This leads to a battle with Yamma's Team consisting of Yamma himself, Goyan, and Macaroo. Tekka's Team must defeat the Yamma or they will fail the mission if they KO either of his two teammates without KOing Yamma himself (KOing all three however works too). After defeating Yamma he will run off and Tekka's Team must chase after him. After tracking him down, he is cornered by Kid Goku. Yamma tells him to give up before it gets ugly and battle them again, this time with Sirami and Nanmu as backup. He is defeated a second time but once again escapes capture. They finally track him down to the tallest building in the alien city of Area 4F. Tired of being made to look stupid, Yamma reveals that he called on some backup from the Demon Realm and that it is the end of the line for Tekka's Team. Goku tells Tekka to watch their back as he has a bad feeling. Yamma then confronts them with Evil Namekian Ghiro and Demon Swordsman Halto both of whom have come from Demon Realm. Unlike the other battles, Tekka's Team must defeat Yamma and his two allies. After defeating Yamma for the third and final time, Tekka's Team manages to capture him. After capturing him, Pan says they should go back to the Saiya Squad who she refers to as "sucky superheroes". Great Saiyaman thanks them for capturing Yamma and states that taking him out was a tall order. Pan says they sure know how to keep Tekka's Team busy and tells Great Saiyaman to do his own dirty work next time, before revealing she remembered Goten's slip up by calling Great Saiyaman, dad. Great Saiyaman laughs and apologizes. Saiyawoman also slips up and calls him Gohan, confirming her suspicions that Saiyawoman is her mother Videl and Saiyaman is her father. Videl apologizes stating that they were only trying to play their part to protect society by keeping people safe from behind the scenes. While Pan understands this, however she asks why they have to wear such silly costumes as she finds it embarrassing. Gohan however insists the costumes are awesome and Goten agrees, causing Pan to sigh and give up trying to reason with them.
