Spaceball I was a ship owned by Planet Spaceball and commanded by Dark Helmet. It was a spoof of Darth Vader's personal Star Destroyer, The Executor, as well as the Death Star. It was extremely long. (After the prologue of Spaceballs finished, it took almost two minutes for the camera to finish panning across Spaceball I.) In addition to some of the rooms usually found in a spaceship, it held a shopping mall, a three-ring circus, and a zoo. Hundreds of people were on its crew. The ship was usually regarded as evil. It had the ability to transform into Mega Maid, a transformer. After much use, Lone Starr pressed its Self Destruct Button, so it exploded. Most of the crew escaped the explosion. However, President Skroob, Dark Helmet, and Colonel Sandurz did not. They ended up crashing on the Planet of the Apes.
Spaceball I was eleven kilometers in length.
