The Demon Lord of Madness, Baytor arrives on earth and becomes a bartender at Noonan's bar; eventually running the joint once its owner Sean Noonan is killed.
His dialogue consists 99% of "I am Baytor!", he is a bit of an enigma (which is just what one would expect of an entity with the title of Demon Lord of Madness). Baytor does, however, have occasional lucid moments wherein he actually says something else, something that is usually relevant to the situation in which it is spoken. Most notably, Baytor speaks a quiet "so long, boys" to Tommy "Hitman" Monaghan and his pals when they leave the bar for the final time; though only speaking when they were just out of earshot.
Baytor can project a white liquid on their enemies, which causes them to dry and shatter and he is immortal.
