Haxus

Haxus is a Galra Soldier which is under the command of Sendak and one minor villain in Voltron: Legendary Defender. His personality is largely unexplored due to his death at the hands of Pidge and Rover, but he exemplified the Galra code, in which the only way to stop a Galra soldier is for them to triumph or die. He can definitely be identified as a devoted soldier and clever infiltration specialist due to cloning the access codes from Rover and implanting them into an unchanged Galra drone.
