Commander Hessler (へスラー指揮官 Hesurā Shikikan?, 1-45) is a sword-wielding field operative in black armor. Hessler oversees the attacks on Earth. He is a proud, easily irritated warrior. Though he encouraged Himley to fight alongside him, Hessler started to regret the decision when Girls 1 and 2 point out to him that his brother might upsurp him. Driven by the justified paranoia, Hessler mortally wounds his brother during their fight with Shaider and leaves him to die. After the death of Girl 1, Hessler heads to Eastern Island to confront Shaider as he make his way to ruins. Their duel transverses from Easter Island to the Fushigi Dimension where Hessler falls to Shaider's Shaider Blue Flash.
