Suggested by Destroyer Roshi is one of the most unlikable characters in all of DBZ. That being said, he is still a DBZ character so he won’t be going down very easily. He can destroy whole planets in a snap while Manda couldn’t destroy a town in that time. Manda would get speedblitzed on all sides and wouldn’t even have time to launch a single attack. He’s simply outgunned. Master Roshi wins.
