Zappa was a 23rd century Zakarak man.
Biography
By 2266, Zappa commanded a contingent of Zakarak spacecraft. Kilima of the fifth dimension and Kalik were two of his associates.
In 2266, when Zappa's ships visited planet Alpha Z-21, they detected two Starfleet officers on the surface. Leader Zappa plotted to capture them. He and Kalik served as a distraction while Kilima tried to capture them with a net. But Captain James T. Kirk and Lieutenant Commander Spock fought back. During the struggle, Zappa raised his zakaram sword and threw it at Kirk, but it accidentally struck Kilima in the back. Zappa then dodged as Kirk and Spock threatened him with phaser blasts at his feet. Conceding defeat, his team fled the area aboard a stolen Alpha Z-21 spacecraft. (TOS comic: "Colouring Book")
