The Doom Ship is King Koopa's giant warship. Koopa and his evil children used it numerous times to invade the Mushroom Kingdom. It is featured throughout the entire The Adventures of Super Mario Bros. 3 series.
like the Koopa Airships in the Super Mario videogame franchise, the Doom Ship was equipped with a huge amount of artillery and Warp Pipes, it's architecture has a segmented wooden exterior, and it's bow has both a metal spiked ram and a gargoyle-like feature beneath it, sculpted like Koopa's head in an iconic way. This aerial fortress also possessed a trait not seen in any games featuring Koopa Airships, the ability to teleport to other different locations.
- It was alternatively spelled "Doomship".
- According to the bonus disc on the Shout! Factory DVD set, the Doom Ship itself was designed by Koopa's son Kooky von Koopa (Ludwig von Koopa in the cartoon version).
