Bvstmnt - mutagen-disseminating machine
The mutagen-disseminating device is a machine created by Baxter Stockman and the Foot Clan in the movie Batman vs. Teenage Mutant Ninja Turtles. It was built at the behest of Ra's al Ghul and Shredder, who had made a deal that required a method of spreading mutagen and Joker Venom across Gotham City.

Stockman was responsible for the actual construction of the device, which required several pieces of experimental technology from multiple companies, including a cloud-seeder from Wayne Enterprises. The machine's construction was delayed due to the cloud-seeder being hidden on a Wayne Enterprises ship, but Stockman was able to complete construction shortly after obtaining it.

The Ninja Turtles and Batman broke into Ace Chemicals in order to stop Ra's al Ghul and Shredder's plan. During the fight, the device activated and began flying upwards, with Donatello and Michelangelo clinging to it. Michelangelo's efforts to turn it off only caused it to mix the Joker Venom and mutagen, and accelerate its ascent.

Fortunately, Michelangelo soon discovered that he could damage the device, and began breaking different parts of it. It soon overloaded and exploded, and the flaming wreckage crashed into Ace Chemicals, where it knocked Shredder into a vat of Joker Venom.
