Gepple is one of the four scientists of the planet of Primus. Though he spends most of his time bickering with his fellow scientists, Gepple can be more level-headed of the three. Gepple is shortest of the four scientists and could be just as cowardess.
Gepple is the famous inventor of sticky substance, known as "Gepple's Goo". Gepple's Goo proved to be quite useful in keeping Flogg's Mutants from using the tubes, that lead to the underground city of Onnor.
- Gepple was voiced by Don Brown in the "New Adventures Of He-Man" cartoon series.
- Gepple only appeared in the "New Adventures of He-Man" cartoon.
- As the cartoon series goes on, Gepple and his fellow scientist appear far lesser than he did in the begining.
