An unidentified person, presumably human, who kidnaps a Mogadorian and tortures it for information. He later contacts They Walk Among Us newsletter to tell them information that he finds.
The Caller has information on some of the Garde, correctly stating that Numbers One, Two and Three had been killed, Number Seven had been trailed in Spain and Number Nine had been in South America. The editors at the newsletter posted a small article about the given information but decided to write more detail about it on the next issue as it was printing day.
Before the editors could call their source back for more information, the Mogadorians arrived to thwart them. The editors speculate the their source, the caller, was found and killed. The caller had a Columbus area code.
