Gira

Gira was a red-haired male Human Jedi Knight assigned to guard a handful of Padawans who survived the Great Jedi Purge. When Darth Vader captured him, Gira agreed to submit to Vader on the condition that the younglings were spared. Vader betrayed Gira and had the transport containing the Padawans blown up. Disgraced, Gira used his lightsaber to suicide.
