|Out of Stargate universe information
The mastadge was a vegetarian domestic animal living on Abydos.
On Abydos, Doctor Daniel Jackson first encounters a mastadge and notices to Colonel Jack O'Neill that this animal has a harness. Yet, when he feeds him with a 5th Avenue candy bar, the mastadge is scarred and runs away in the desert, dragging Jackson by his leg. Later, the animal, is quiet, liking Jackson.
- The mastadge is supposedly extinct as Abydos has been destroyed by Anubis in 2002 (SG1: "Full Circle").
Behind the scenes
- The voice of the mastadge has been performed by Frank Welker.
- When Daniel Jackson is dragged by the mastadge in the desert, it was actually a dog with a miniature mastadge costume who has been used to run and drag a puppet looking like James Spader. For the full scale version, horses were used with skeletons and hairs.
