Nike is a flier who first appeared in the third book Gregor and the Curse of the Warmbloods. She is the princess of the fliers, being Queen Athena's daughter. In Gregor and the Marks of Secret, she plans to bond with Howard after his first bond, Pandora dies. She is white and black striped. She has a running joke with Boots about the fact that they are both "pincesses." In Gregor and the Curse of the Warmbloods, she substitutes for Ares as Gregor's flier. She is injured when the group is attacked by plants in the jungle, but refuses to take any pain medications, believing they will muddy her thoughts. Like Howard, she harbors a deep disdain for the shiners.
