The Covandu are a liliputian species in the Old Man's War universe, the tallest only measuring an inch, but otherwise very similar to humans. Their aggression in colonizing planets is similar to humans' as well, sometimes causing conflict. One human colony was taken over by Covandu when it was abandoned due to a virus (which did not affect the Covandu). After developing a vaccine, humans returned to take it back by force.
They are gifted in the arts, specifically poetry and drama.
