With some maneuvering, he and Tron take over the MCP and kill sark, proving they're the most badass guys in the mainframe.
En route, Tron encounters the MCP's henchman, sark, and the two battle it out cyberstyle.

"shirt, body garment of linen or cotton for either sex," late Old English serc "shirt, corselet, coat of mail," surviving as a Scottish and northern dialect word, from Old Norse serkr, cognate with Old English serk (see berserk). But Gordon lists it as a loan-word from Latin sarcia; other sources are silent on the point. Cf. also Lithuanian sarkas "shirt," Old Church Slavonic sraka "tunic," Russian soročka, Finnish sarkki "shirt," all of which perhaps are from Germanic.
