Gedd

Gedds are apelike aliens that live on the same world as the Yeerks. They were the first species to be mentally dominated by the Yeerks. They are primitive, barely sentient creatures with an odd asymmetrical feature in their biologic design; they have one leg that is longer than the other. Because of this, they will often have one arm on the ground, acting like another leg. Only low-ranking Yeerks still have Gedd hosts, higher ones prefer to control a Hork-Bajir, Human, or Taxxon. When speaking, Gedds roll their R and S letters.
