King Cold's ship is presumably his base of operations. While the ship was searching through Namek's remains for Frieza, King Cold broke his ship's window (causing one of his men to fall into space's vacuum). When the captain discovered Frieza, they brought him to the ship and took him to King Cold's planet, where King Cold's top men built Frieza's cyborg body parts, thus Mecha Frieza was "born".
They land at Northern Wastelands, and order their soldiers to begin the attack. However, a mysterious youth unexpectedly shows up. After the young Super Saiyan kills both Frieza and King Cold, he blows the ship up with a powerful God Breaker.
