Delta

Delta is the leader of Metro City's Anti-Robot Robot Squad, a division of the Metro City Police dedicated to fight crime caused by robots. He is a stubborn but passionate officer and an ally to Astro Boy. Delta first appears in the 2003 series episode "Robot Hunters", and also appears throughout the Akira Himekawa manga series.

Appearance
Delta is a bipedal humanoid robot. He is especially tall and strong in stature, built as a typical strongman-style utility robot. He is covered in armour that also serves as his regular uniform: a blue jacket with wide shoulderpads, white bodysuit, navy blue boots, and gret utility belt and detailing.

Delta's face is angular and humanoid, made of grey metals, and mounted securely to his neck. His eyes are yellow signal lights; they can either light up when needed, or scan and analyze his surroundings.

Personality
Delta is a true lawful good. He is stern and serious, having been designed to follow the law at all times, but he is still quite compassionate. When Astro first meets Delta, he is surprised to hear how strongly Delta believes only his squad is qualified to fight robot crime. Delta also immediately shoots down Astro's attempts to help them. This turns out to be because of Delta's instincts to follow the police rules, as well because of his pride as the squad leader.

Inspector Tawashi regularly works alongside Delta in the series. Delta regards Tawashi as his ally and colleague, but dislikes Tawashi's occasional derogatory remarks about robots.
