Cronos

Cronos was an Imperial Senate Guard that served in the Galactic Empire's Senate Building Security. Around 19 BBY, an assassin breached the Senate Building on Coruscant, intending to kill Emperor Palpatine. However, Vex and the guardsmen Yuri Harkov, Denson, Vex, and Polk intercepted the assassin. He killed Cronos and most of the squad, excluding Yuri, who managed to overpower him.
