A gang boss on Sigma Iotia II who competes with Bela Oxmyx and kidnaps Kirk to get his own share of Federation weapons.
Jojo Krako is a boss of one of the territories on Sigma Iotia II and Bela Oxmyx's chief rival. In A Piece of the Action, he is just as eager as Oxmyx to get Federation weapons, and when he learns about the visitors he kidnaps Kirk.
Kirk escapes and, with Spock, forces the bosses into a deal. Krako becomes Oxmyx's lieutenant in the planet's new unified syndicate, which Kirk hopes will lead to genuine government. He was played by Vic Tayback.
