The man-sized, 400 lb xeemus are mean-spirited, aggressively stupid avians that accost any humanoids they encounter.  They love shiny trinkets and weapons, and rob travelers unlucky enough to enter their territory.

Quite dexterous, a xeemu can wield 1 weapon (via prehensile feet) in combat. However, the unique resonances of energy-based melee weapons (vibro-swords, warp-field maces, etc.) drive them into a panic.

Xeemus produce live young, and carry their hatchlings in abdominal pouches.

Mutations:  Aberrant Form (Pouch, Prehensile Feet), Increased Balance, Neural Telekinesis, Phobia (Energy HTH Weaponry) [D], Teleport
