My suggestion for Chapter 90 of the Dragon Ball Super manga

[Benjamin-Simons-91]

I have this idea for 2 years now, which should have been the 90th chapter (right after Betas #1 and #2 are defeated), where Yamcha's club host career (as stated in an interview with Akira Toriyama by Mandō Kobayashi, March 24, 2013) is finally fleshed out for us; So, Yamcha retires from his professional baseball career (the "Titans" are finally shown/referred to in the manga) and enters as a small part owner in an existing fancy club.

As he invites Tien (accompanied by good Launch) and Chiaotzu to grab a look at his new business ("drinks are on me"); Dr. Hedo's Beta Androids 3-6 are ganging up on Goten and Trunks who were hanging in West City with their friends, scaring the normal kids off, while Goten and Trunks run across the area, until they arrive just in front of Yamcha's new business.

The Beta Androids prove troublesome for the Saiyamen X1 & X2, as they fight in perfect coordination. Yamcha and Co. sense Trunks' and Goten's energy signatures and rush to the window (as the club crowd is partying) and witness the battle.

Tien asks Launch to take cover and wait for them in the club, and leads the way as he's the fastest, with Yamcha and Chiaotzu close behind him, and they step down to the street. As Trunks and Goten are stuck in the ambush, and can't transform as they're getting kickboxed all over. Tien and Co. step in to buy them time.

Tien uses normal Kikoho at one of the Betas, forcing the others to take cover as the attacked one is all dusted.Yamcha charges a Kamehameha at the second Beta nearest to the OG Z-Fighters, and cause the two remaining Betas to jump at Yamcha and Tien, kicking them to the ground. Chiaotzu uses his Telekinesis to lock the Betas' movements (as he did at Goku back when he wanted to fight Monaka), saving Yamcha and Tien from getting beaten up.

Goten and Trunks turn into Super Saiyans and beat the Betas with Hedo yelling at his screen.

It's a fun idea, but I think tying Ten, Yamcha and Chaozu into the Super Hero prologue makes their absence in the movie a bit weird. But yeah more side stories with them would be good.
