|Abilities||Turning his ring into a rocket|

Don (ドン) is a power user and a member of the Robert's Ten. Don is very proud of his strength and he always has a huge grin on his face even though he has a very large mean streak to him. Don is easily pleased and flattered when somebody says he is strong, like in the manga, and likes to show off at certain times. Ueki retires him from the tournament with his new-found ability of Masshu.
Don has 320 talents, all of brute strength. In the manga, Don only has 52 talents, but their strength more than makes up for their number. Don presumably lost his talents by indiscriminately beating up people outside the tournament to show his power.
His power was to turn his ring into a rocket. This ability suited his brute strength, and was used in counterpart to maximize his offensive capabilities. His power is later used by Karlpaccho, while facing Ueki.
