Edgar is a character in the HD Universe appearing as a phone contact in Grand Theft Auto V and Grand Theft Auto Online.
Edgar is an unseen character in GTA V and GTA Online, the only way you can discover his existence is through dialing an number otherwise unspecified in the game. Dialing the number 611-555-0146 into your phone in single player or online, will give you the following message:
"This is Edgar, call back some other time."
Edgar has a slight accent and seems to be middle aged. It is unclear at this time if Edgar was a cut character, or if he is a character planned to appear in future DLC.
