Brown is vengeful ghost of the Crewmate originally seen in the background of Reactor in V3. It faces off against Boyfriend in the song Esculent. Brown is a typical ghost dead players turn into in Among Us, having a faded color from its actual body and with a dissipating tail at the end. It still wears the same toilet paper on its head. It wears small circular glasses on its cracked visor, and has a knife half embedded in its head. It reveals a large, realistic mouth in its up pose. Brown was designed and composed in the final days of the mod. Brown is very similarly designed to the scrapped "Dead Impostor", and by extension, Gold from Friday Night Funkin' Lullaby.
