Mighty Man & Yukk is an animated series created by Ruby-Spears Productions. It aired as part of the 1980-1981 show The Plastic Man Comedy/Adventure Show.
Millionaire Brandon Brewster uses a machine to reduce himself to only a few inches in height and give himself superpowers, including super-strength and flight; in this form, he’s the costumed crime fighter Mighty Man. His partner is Yukk, the “world’s ugliest dog”; this anthropomorphic dog conceals his face by wearing a miniature doghouse on his head. The sight of his face destroys anything Yukk looks at. Mighty Man and Yukk are called in by the Mayor of the city to fight different supervillains
