They were seen in a single story arc, in which they captured Spiff on the planet closest to Star X-351. They brought him to their spaceport for transport to labor camp; when Spiff's valiant escape attempt failed, he was brought before the "Zogwarg Queen" (in reality his mother). The Zogwargs were seen riding rocket scooters to catch up to Spiff's emergency jetpack. The Zogwargs appeared as giant worms with tentacle-like arms but no legs, a shelled torso, a perpetually gaping jaw, no eyes and a single antenna on top of their head.
