A Watcher resembles a small theropod dinosaur, possibly an alvarezsauroid due to their reduced forelimbs. Watchers are primarily deployed in groups around herds of small terraforming machines such as Striders, Grazers and Lancehorns.

A Watcher’s optical sensor array or “eye” is its sole tactical weakness, and its size and position make it a highly vulnerable target
