I guess I will be different here and just say, I didn't really care for this chapter.
The whole, 'we need every fighters we can get' is undermined by 17, 18, and even Goten and Trunks literally never being mentioned. 17 is the most annoying since freaking Yamcha is mentioned before him and he's one of the strongest people on the planet. Second only to Gohan going by this chapter (personally think 17 is stronger even going by the manga, but whatever). 18 makes no sense since she lives with Krillin, but didn't even get 'stay with Maron' like Resurrection 'F'.
How the criminals got to the Lookout is a little too contrived for my taste. Like how did they arrived exactly on the Lookout instead of some random desert. All they knew was that they were supposed to go to Earth. That and them robbing some random planet who just happened to have someone with a warp ability is a little much.
Piccolo's fight has some interesting moments, but was overall boring to me since Toyo took the most boring route for a mirror match. Namely, most of it was just Piccolo and 73 doing the exact same moves at the same time and Piccolo looks like a noob being unable to counter his own techniques. Which is really annoying since a similar gimmick was used in Rurouni Kenshin and the person who was the copier got his ass handed to him because copying something wasn't the same as mastering and he was fighting the person who invited said technique, so they knew all the weakness and flaws in it. So for someone who is as smart as Piccolo being unable to really do anything is just eye-rolling. And I'm not asking for Rurouni Kenshin's level of writing here, just that Piccolo shouldn't have been so helpless to his own techniques and movements.
How Goku got UI doesn't matched how he did it in the manga. When he got it, he got it by thinking of his past masters and what a meat head he was being, not because he was pushed to his limits and was about to die. That was in the anime. And what funny is when Merus said that they needed to recreate how Goku got UI, I told someone that they needed to get Roshi so he could flexed to Merus.
Overall, this chapter wasn't bad, but it failed to do what it was supposed to in my eyes. Build tension since Goku and Vegeta aren't there, when the Z-Fighters didn't even try to invite someone who is within the same league as them in 17, nor other powerful fighters like 18. That and Piccolo having trouble against his own fighting style really doesn't make 73 look dangerous so much as making Piccolo appear as a mediocre fighter.
