How did Emma deal with the villains past Raditz?

Considering Kami tells Goku that North Kaio is stronger than Emma and Kaio tells Goku that Nappa and Vegeta are stronger than him.

My guess is that it was similar to what was shown in filler. Enma was able to transport them to hell without getting physical before they could attack, seeing as how none of them were out of control enough to immediately start a commotion other than Boo. He may have even done so as soon as they got in line at the Check-In Station for additional safety.
