Ugly John is a mutant in the Marvel Universe. The character, created by Grant Morrison and Frank Quitely, first appeared in New X-Men #114 (July 2001).

Within the context of the stories, Ugly John is an Australian mutant possessed of three faces. Ugly John is rescued from the giant mutant-hunting robots known as the Sentinels by Cyclops and Wolverine of the X-Men. En route back to Westchester, the X-Men's X-Jet is shot down by more Sentinels over Central America. Captured by Cassandra Nova, the genetic twin of Professor Charles Xavier, Ugly John is to be executed but the attempt fails. To ease his suffering, Cyclops shoots John with an optic blast.

U-Go Girl (Edie Sawyer), is a mutant in the Marvel Universe, a member of X-Statix. The character, created by Peter Milligan and Mike Allred, first appeared in X-Force #116 (May 2001).

Within the context of the stories, U-Go Girl can teleport herself and others (in a radius of five feet) across the globe, although this process is physically draining. Edie becomes pregnant by a young drifter when she is fifteen, and her parents decide to raise the girl as Edie's sister rather than daughter. Edie's power of teleportation fully manifests when she first looks at her daughter's face and feels a powerful urge to "get away." She teleports to Los Angeles. Edie struggles as a waitress and an actress until she becomes smitten with X-Force leader Zeitgeist and decides to try out for the team. She perfects her "aim" with her teleportation and comes up with the codename "Tele-Girl"; she becomes U-Go Girl after she accidentally flashes a crowd during her team tryout and someone screams, "You go, girl!"
