The Death Flower is a giant space station shaped like a flower. It was built by the Empire. The Death Flower can shoot giant rays of ungoodness that can destroy an entire planet! Bob attacked the Death Flower once. Unfortunately, his spaceship was blown up and he had to use his self-destruct button to destroy it (It was the first Bob).
The Death Flower did belong to Darth Flower (before it blew up).
Mr. Robot was killed in the explosion (supposedly).
