Metal Slug 8 (Lord Moogoo)

The Martians do not appear in the game, but appeared in an opening cutscene where they left general Donald Morden after finding their alliance with the rebel army unreliable.

At the end, a cutscene shows that they have been found to be working with the Ptolemaic Army on an alien planet, seemingly creating a new hybrid alliance. It seems like the Ptolemaic Army is also offering them reliable protection from remnants of the Invaders from Metal Slug 6.

Metal Slug 9 (Lord Moogoo)

The Martians had joined Ptolemaios to help protect themselves from the Invaders, who had seeked revenge after their defeat. The aliens were enraged to see Morden appear, knowing how many Martians they lost under his leadership. They, however, were backstabbed by Ptolemaios, who actually helped the Invaders.

However, the Martian leader, the Professor and Percier, along with some heroic Martians decided to break free from their oppressive leader, Ptolemaios. By letting Morden escape, they all teamed up to destroy the Elder One.
