Well the plan was for him to join forces with Raditz as soon as he got there, but because of how diako attacked him, he threw that out the window, as why wouldn't Raditz a member of the same species act any differently? Also I don't remember who but someone got stuck with Diako cause the person never followed up after Josh left.

That would be me. I already decided I'm going to post today because I'm tired of being stuck.

Anyways, there are plenty of options to avoid having too few villains to go around. Apart from my suggestions involving Saibamen and Movie Villains, these are also possible solutions:

1. The Frieza Force is an army spread about the entire galaxy. Just because we only see a fraction of it in the show doesn't mean we can't incorporate more of it to provide a larger force for us to deal with on Namek.

2. The Androids/Cell Arc... I won't lie, this one's going to be difficult to deal with. There aren't any underling type enemies to speak of apart from Cell Jr, and those didn't show up until the actual Cell Games. Until then we're just going to have to decide ahead of time who's going to be the most useful in defeating Androids 16 through 20. I think my suggestion involving the movie villains would be most useful here, since we could then throw in 13, 14, and 15 in addition to the main 5.

3. The Buu Arc had me stumped for a while, since the closest thing Buu gets to underlings is splitting himself up into Mini Buus. But then I remembered something crucial... and that is Dabura. His role in the actual show is short and he ends up (much like many characters) criminally underused. But Dabura is the King of the Demon Realm, which suggests that he naturally has his own army of demonic servants and warriors, right? So what if Babidi not only employed Dabura but also Dabura's army along with him?
