*NOTE* There are no power levels given after the Frieza saga, that's because scouters weren't used again, except for once very briefly after the battle on Nameck. If you see a list of power levels on the Internet that has power levels AFTER the Frieza saga, don't trust it. It's only speculation and opinion.
