Hola amigos!
Setting a personal record with actual started threads here, let's see if 5 low class Saiyans, none of whom could take a Saibaman in a fight, can take down one whistling madman.
Step 1: Default match. The Saiyans don't start with anything in particular except for their relatively useless Saiyan armor from that period. And a box of Pop Tarts. Because who doesn't like Pop Tarts.
Step 2: If Yondu is too much for them (and he may well be), they can start off in Ozaru form.
Step 3: If they are too much for Yondu in step 1, let's make this take place in, oh, Xandar's capital city, they start off 2km apart. Yondu wants their Pop Tarts. They know he's coming for them (Pop Tarts are worth 50K units each in spaaaaaaaace), but don't know where he is or what he looks like. There is no moon.
The ball is now in your courts, gentlepeople.
