Giant Spaceship

The giant spaceship was the headquarters and mode of transportation of the Dark Matter Thieves. The ship possessed incredible firepower, capable of destroying the majority of A-City in an instant. It crashed after Saitama shattered its power source. The ship was salvaged by Bofoi, who is now trying to use it to develop new technology.

Appearance
In the manga and anime, the ship is shaped like a tooth. In the manga, the ship is colored Steel Black, in the anime it is Purple. The ship was massive in size; it was large enough to cast a shadow over the majority of A-City and was able to destroy 99.8% of the city with a single shell bombardment directed downward.

Trivia

 * In chapter 33 of the manga, Saitama is seen walking through a maze-like section of the spaceship. The drawing used as the map here is called "Papa's Maze", an incredibly detailed labyrinth created by Kazuo Nomura.
 * According to Genos' notes, the size of the Dark Matter Thieves' ship is 9,230m x 15,024m.
 * Murata stated that it takes around 4 hours to draw one panel of the spaceship (round up to 6 hours when including the sketches) as a fun fact on his stream. He did not let his assistant handle this part and he kept redrawing.
 * The ship is made from a special metal alloy not found on Earth.
 * The ship is so resistant that it didn't fall even after a series of Saitama's "normal punches".
