 Have you ever heard the legend of Guest Zero? Also known as the Old Guest by most Roblox users. The legend states that Guest Zero was a very rare occurrence, or even a digital anomaly. Guest Zero's appearance has always remained the same throughout each sighting. It always resembled the appearance of a guest from 2010, a black art cap, gray shirt with the art logo, light blue pants, and white skin. The first report of the entity was in 2011, and it was apparently seen in Welcome to the Town of Robloxia. The entity was seen walking around aimlessly, and not really doing anything or interacting with other players. The entity's behavior was also strange, as it would always run away from players coming near it. No matter how much the players caught up, they couldn't seem to get closer to Guest Zero. It was also reported to have an effect on the players that the entity visits, mostly creating bad luck for the players in the game. So let's say a player was playing Disaster Survival, in the same server as Guest Zero, the disasters would be much more catastrophic. Anyway, many people dismissed the legend, due to Guest Zero's behavior being so consistent with each sighting, many people say that Guest Zero was just a bot, created by Roblox staff as a test for the best numbering system, but almost everyone knows this isn't true. Due to Guest Zero's effect on the games it visits. Below are the most popular sightings of Guest Zero in order of here. Town of Robloxia, 2011.
