@WorldEater: Gohan still takes this.
Gohan, before going super saiyan 2, was higher than Vegeta's 'Super Vegeta' form. That form was much more powerful than 18. 18 while not being very serious, still did fairly well against both of them. They having the advantage over her by knowing who she was too.
The apes are kinda angry and are thinking they want a planet all to themselves.
