Graphon Narmolis

Graphon Narmolis, a shape-shifting criminal, was on the Shadow Proclamation’s most wanted list. From the planet Speldron he arrived on Earth, where, assuming the identity of a cool pencil, gained an influence over the schoolgirl Janie who he sought to use to hide his whereabouts.

Unfortunately for him he was tracked by the Eleventh Doctor and Amy Pond to Janie’s school where the Doctors mind, resistant to his psychic influence, enabled his recapture. . (DWAM: Pencil Pusher)
