The Mother Ship was recognizable for its purple, enormous and bulky appearance, coupled with relatively short, sturdy wings. Along with areas built into the ruins of Chozodia, a docking bay was constructed containing Space Pirate Fighters. When ships entered or left the Mother Ship, a door in the front would open, resembling a mouth or beak.
The Mother Ship housed the incomplete Ridley Robot, a safeguard created in Ridley's image in order to protect the ship in his absence. This Robot was connected to the Mother Ship and its destruction caused the triggering of a three, five or seven minute (depending on difficulty level) countdown to the destruction of the Mother Ship as well. After Samus' escape, the ship's interior started to glow red (which could be seen through the ship door) and the ship fell apart with an explosion, leaving it a scorched wreck.

The Mother Ship is not present in the original Metroid game, but rather in the extended ending in the remake, Zero Mission. Following the defeat of Kraid on Zebes, Ridley receives a distress signal from the planet in the ship's bridge and changes course, heading straight for the planet. By the time Kraid's killer entered Ridley's Lair, the Ship had landed, and Ridley made his way to his chamber.
Once there, he was surprised to see the challenger was Samus Aran, whose mother and father had been killed by him in her early years on their home of K-2L. Now a young woman, Samus had become a Bounty Hunter and was sent to destroy the Metroids and Mother Brain. Ridley attacked Samus, but she prevailed and left him severely wounded.
Following the defeat of the Mother Brain, Samus escaped Zebes but was shot back down to the planet. Without a choice, Samus undertook the "foolish" task of infiltrating the Mother Ship, armed with only her Paralyzer (her Power Suit had been destroyed in the crashing of her Gunship). Samus escaped the Mother Ship and encountered the Ruins Test, which she completed. Rewarded with a Fully Powered Suit, Samus returned to the Mother Ship and slaughtered any and all Space Pirates in her way with her newly-enhanced weapons. She finally confronted the Ridley Robot and destroyed it, then escaped the exploding Mother Ship in a hijacked Escape Ship.
The destruction of the Mother Ship would seem to imply that the remains of the ship would be re-explored by Samus during the events of Super Metroid, known as the Wrecked Ship. However, the Wrecked Ship is known to be of Chozo origin, and in Zero Mission when exploring an expanded Crateria Samus will enter a section of it which has a close resemblance to the Wrecked Ship. Additionally, Yoshio Sakamoto dismissed the possibility of both ships being one and the same - during Zero Mission Samus passes through an area that appears to be outside the Super Metroid Wrecked Ship in Crateria, whilst the Mother Ship has not yet landed.
In the Metroid Manga it is again seen as Ridley's flagship, fighting against the Federation Army Special Ops Battleship Vixin IV. Midway though the battle it tried to warp to Zebes but is stopped by Adam Malkovich in the Vixin IV, knowing that if it makes it to Zebes it would effectively put an end to Samus' Zero Mission. Eventually, Ridley is able to make it to Zebes with his ship, but Samus was nevertheless able to defeat him and eventually destroy the Pirate vessel.
In Metroid Prime: Episode of Aether, Samus destroys a Pirate vessel that was attacking a transport and passenger ship, and reports that the "Space Pirate Mothership [has been] eliminated."
