Space Pirate Mother Ship

The Space Pirate Mother Ship is a location in Metroid: Zero Mission that Samus Aran had to infiltrate after her ship was shot down by space pirates, while wearing nothing more than her Zero Suit and carrying an emergency stun pistol. The ship belongs to Ridley, who landed it on Zebes after receiving a distress call from the planet following Kraid's defeat; a prototype robot in Ridley's image was being constructed in one of the ship's rooms, which served as the game's final boss.

In M.U.G.E.N, the Space Pirate Mother Ship has been created by Enscripture, using sprites of the robotic Ridley's boss room from Metroid: Zero Mission.

Enscripture's version
Enscripture's version is a very small stage with barely any left or right camera movement past the starting point and no vertical camera movement at all, which heavily restricts characters that rely on air combos. The stage's sprites are taken from Metroid: Zero Mission, though the background sprite has additional black surrounding it to fill out the sprite so that it is large enough; a problem with the pipes at the top of the stage is that they considerably obscure lifebars that sit in the layer behind the characters, to the point where, depending on the lifebars, it is extremely difficult to tell how much Life or Power a character has. The stage has two .def, with the .def titled 'MZM-MechaRidley' having a temporary splash screen appearing at the start of the match of the robot Ridley's eye opening, while the other .def titled 'MZM-MechaRidleyNI' omits this splash screen.
