Guest 666 is a Robloxian who was shunned by the community because of the dark myth surrounding them, which claimed they were a dangerous hacker. Their life changed when they met Noob, eventually forming a romantic bond. At first, their relationship was filled with games, parties, and joy. Over time, however, Guest 666 became increasingly erratic, resorting to injecting themselves with scripts for strength. This created a growing rift with Noob, culminating in a tragic and violent breakup. Cursed with their name from the moment of their existence, he had managed to find solace in Noob. Someone who saw them for they were inside, but that ideal reality would not last. Guest 666 will viciously rip and tear through any obstacle in his way, feasting on the bloodshed and carnage to empower his abilities. Guest 666 has some resemblance to their origin, but their design is quite different. Guest 666 has a pitch-black head, a black cap with a red brim with an "R" on it, and "Roblox" written across their torso and arms. Their hands and claws are a bright red with a black outline seemingly made out of solid material to resemble chains, their horns are bright red and lyre-shaped, his legs are unguligrade, and their hooves have a red "flame" effect. They also have a large dark red "mane," and a bright red tail with the Roblox logo at the tip of it. Most of Guest 666's body has the metal texture, and their kneecaps are spheres with a metal rim above them. Guest 666 also has a red face, with a large mouth that makes a creepy smile, black teeth, and wide, red, seemingly bleeding or bloodshot eyes.
