So  overzen and I iterated some more on the old, fat superhero idea, and came to a concept for a gadget-based superhero called Dober-Man. He's got treats for the good dogs, and a butt-kicking for the villains!

ALT TEXT: A drawing of an older, fatter superhero called Dober-Man. He wears a black body suit with a brown panel running down the center of the torso and inner thighs. He wears a black cowl and cape, much like DC Comics's Batman, though in his case it's in the shape of a doberman, complete with cropped ears and two patches of brown right above the eyes. The reverse of the cape is gold, as well as his belt, the trim of his gloves and boots, and the doberman insignia on the belt. Finally, he has several pouches on his belt, as well as a holster on his left side with a bone-shaped boomerang.
