Sinbad Jr. and his Magic Belt

Sinbad Jr. and his Magic Belt is an American animated series made by Hanna-Barbera for the American International Television division of American International Pictures, which originally aired in syndication from September 11, 1965 to May 28, 1966.

Sinbad Jr. is the teenage son of Sinbad the famous sailor, and he traveled the world in his single-masted sailboat seeking adventure and wrongs to right, fighting such villains as the big, black-bearded Blubbo and the mad doctor Rotcoddam. Sinbad Jr. gained the strength of 50 men whenever he tightened his magic belt, causing the diamond-shaped buckle to flash like lightning and temporarily transform him into a mighty muscleman.
