Boss's headquarters is a location in New York City in the Teenage Mutant Hero Turtles Adventures comic series. It is the lair of one of the city's most dangerous kingpins of crime, The Boss. The area the Boss uses as his office has a desk and some filing cabinets, while the remainder of the building is an abandoned warehouse. After having April O'Neil kidnapped, the Boss leaves a ransom note for the Turtles directing them to the warehouse. It is a spacious area with steel supports and thick walls. Several rooms connect to the warehouse space and there are at least two entrances from the outside. The Boss and his thugs stand near one entrance, waiting to ambush the Turtles, but they come in behind the villains. After making short work of them, the Turtles demand to know where April is being kept. The Boss tells them she's in the next room, which is where they find her tied to a chair and gagged. April attempts to warn them that the Boss rigged a trap - the opening of the door tripped a device that began filling the room with a deadly gas. The Turtles get April out of the room and then take the Boss and his thugs to the police.
