[@NacNak]I don't think there will be enough of those Saibamen to go around. Piccolo said that each person would have to take four on, and I'm tracking that there are "12 Saibamen." But the amount of characters actually at the scene is about 9 people, which is about 32 would need to be summoned if not more, and yes, I included the NPCs. Unless people were also meant to be fighting the Saiyans alongside fighting the Saibamen.

Usually when there's a boss battle that has hordes of minions, I wouldn't even put a number to them because people tend to kill way more minions than there are on the battlefield lol. You'll say there's 12 and everyone fights 4, which there will be about 36 enemies in result unintended.
