The mini for the original Stargate movie is the mini-Mastadge. They first appeared at the Stargate Official Fanfiction University, where they were used as beasts of burden by the staff, and serve as security alongside the local Wraith population. The campus sometimes has a Mini-Mastadge Kickball Tournament. The first student the minis catch tackling a canon character is the kickball.
Each of these minis wears a leather collar with their name inscribed on it. Mini-Mastadges don't smell as strongly as actual Mastadges, but are much more vicious, being said to hunger for fan flesh.
The Mastadge is an animal that lived on the planet Abydos. They are swift, four-legged animals with keen senses of smell. They are adapted to the desert ecosystems of Abydos, with shaggy fur protecting their bodies from the cold of night, and the ability to breathe during a sandstorm. They have been domesticated by the planet's people as beasts of burden, and farmed for their fur and meat.
