GB is a Gameboy EXE created by user @MarcoJurez19. He is based off of Mario's appearance in Super Mario Land 2: 6 Golden Coins. He is specifically from a Bootleg pirate copy of Super Mario Land, but his true origins are unknown. He likes to play with his victims, who dare play his game. He can even manifest in his players head, and come into the real world, however mostly chooses not to, as he believes limiting himself makes things more fun.
