Danger Mouse

Danger Mouse (Also called "DM" by Colonel K and "Chief" by his assistant) is an antromorphised mouse and is known through out the series as the greatest secret agent in the world, a secret agent so secret that even his codename has a codename. He wears a white body suit with a titanium alloy red badge (which saved him on a couple of occasions) with the initials DM in yellow.

He also wears a black eye-patch over his left eye but it is not revealed how - or if - he lost his eye. Although he is seen with two eyes in 'Custard' after being zapped by an alien, he is seen with only one in 'The Four Tasks of Danger Mouse'. However he is called on more than one occasion 'a one eyed white mouse', hinted that he may have lost his eye.
