The Zeps are beings appearing in the animated series The New Adventures of He-Man.
Zeps are creatures living in Nordor. They look small and fuzzy, but they actually are androids, and able to become bigger ferocious beasts.
The New Adventures of He-Man
The Zeps' first major appearance was The Gift, where they are the titular gift given by Flogg to the people of Primus as a peace token, but this is actually a trap, as the Zeps take their bigger forms and help Flogg take over Primus.
The Zeps remain part of the Mutant army throughout the episodes of the Mutants having control of Primus, until the Scientists of Primus find out that mud can short circuit the Zeps.
