The gesaw rat was a small quadrupedal rodent from the moon of Carreras Minor. Gesaw rats had thick blue hides, and fed on power.
Several inhabited Ania Solo's junkyard. One scared Solo's friend Sauk, who was unfamiliar with the species. Several others later fed on the remains of SD, who had been destroyed by Darth Wredd who was posing as Imperial Knight Yalta Val.
