flshback to literally the greatest fight in the whole series.
i hpe vegeta realizes that kaioken was a gambit and that , in there first fight, goku wasn't nearly strong enough to defeat him in single combat. a lot of Vegeta's loss that day was because the saiyan prince saw kaioken and assumed incorrectly that goku could reach that power level any time he wanted and for any duration of time. if Vegta hadn't wasted his strength on the moon ball, he'd have won quite easily
