Housemon

Housemon is a minor villain, a minion of Puppetmon and the hideout of Puppetmon.

Digimon Adventures 01
After Puppetmon knew he was going to lose, he had one final trump card. His own mansion turned into a monster made of wood. It seemed to be unstoppable monster because the Digimon's attack had no effect on it. It had only one weakness, Puppetmon. If Puppetmon dies so does housemon. When Puppetmon made his escape, MetalGarurumon and Matt appeared out of nowhere. He thought that MetalGarurumon was working for him and ordered him to attack the DigiDestined. MetalGarurumon refused and killed Puppetmon. Doing so destroyed Housemon as well.

Trivia
It's unknown if Housemon is it's real name, it could be just a nameless robot.
