Trivia
Guest 666 is based on the iconic Roblox myth of the same name that gained fame through its rumoured frequent disruptions and hacking of Roblox games, as well as being featured in a popular YouTube animated series made by 0bliviousHD. The myth said that Guest 666 had admin powers in any game it joined, also having the ability to chat (something regular Guests couldn't do).
The myth said that Guest 666 had admin powers in any game it joined, also having the ability to chat (something regular Guests couldn't do).
Guest 666, 1x1x1x1 and John Doe were in the game Forsaken, before being added to Steal a Brainrot. But it's not from Forsaken, but instead an iconic myth. This led to controversy among the Steal a Brainrot community, with Forsaken players saying that Sammy copied Forsaken. This is false as Guest 666, 1x1x1x1 and John Doe were BOTH made before Forsaken and Steal a Brainrot were released. Sammy was simply catering to old Roblox.
