The Martians are the most recurrent alien enemy of the Metal Slug series. Led by the giant Rootmars, they are extremely intelligent beings and mainly communicate through telepathy, even though it was shown they are able to speak. Their main goal is to conquer the Earth and subjugate humanity in order to save the planet from being depleted of its resources. To reach this objective they have often tried to weaken Earth's military forces through various schemes. They betrayed and manipulated numerous factions, (mainly the Rebels) before trying to invade.

Several humans have joined the Martians. The Martians do not mind human allies for their cause, as they provide them with various equipment and even allow them to command units.

History

Martians are psychic based alien lifeforms with a clear hierarchical structure and a generally benevolent nature. They however severely despise and eradicate inferior races that deplete their home planets resources and wellbeing. Their technology heavily relies on energy manipulation and genetic/biological engineering together with necromancy. Methods of reproduction are unclear.

Metal Slug 2

The Rebel Army was supported by the Martians but unbeknownst to them, the Martians were only planning to weaken the Earth's military. Revealing their involvement and true intentions at the end of the Final Mission, the Martians betrayed the Rebel Army and abducted Morden. The Rebel Army and the Regular Army allied briefly against the alien menace to rescue the general.

Metal Slug X

Their role in this game is the same as in Metal Slug 2 except this time around the protagonists come in contact with the Martians as early as the fourth mission.

Metal Slug 3

The Martians captured Morden again early on, replacing him with a doppelganger who is revealed at the rocket site. Therefore, the Rebels allied momentarily with the Regular Army once the ruse is exposed by protagonists.

Metal Slug 6

The Rebel Army allied with the Martians again after events of MS3, however, another alien race named the Invaders attacks the Martians and the humans worldwide in the midst of the battle. A triple alliance is formed with the Rebel Army and the Regular army in order to destroy the Invaders' nest and put an end to the new threat.

Metal Slug 7/XX

In the game's credits, they are seen saving Morden after he is apprehended by the Regular Army. The Martians also make a return as fightable enemies in Metal Slug XX. This could be showing that they allied themselves with the Rebel Army, along with the Future Rebels.

Metal Slug Defense

In the game's 1.19.0 patch, Rootmars was betrayed by some of his people and requested help from the Regular Army to fight against the rebelling Martians, who had sided themselves with the Invaders.

Metal Slug Attack

It is revealed that Rootmars traveled back to Mars to recover, and left behind a small Martian base, which is currently run by the Neo-Martian Marty and the Professor. Due to the Professor's views on humanity, the Martians clash with almost every faction, though they tend to battle the Rebel Army the most.

Despite the physical weakness of the Martians, the Professor has worked hard to help the Martian cause, creating new equipment and lifeforms. Most of their attacks are laser based, making them significantly dangerous against conventional equipment.

Metal Slug: Awakening

After the Martians defeat at the hands of the Regular Army, they later allied themselves with silicon-based lifeforms known as the Concerians and are seen fighting the Regular Army along side with Rebel soldiers who have been captured and mutated into the Mutated Morden Army. the martians have shared their technology including their drones to their new allies.

Trivia

A gray Martian who had taken General Morden's appearance

• The Martians are based on old 1950's B-movie flicks and some alien movie flicks.
• The primary Martians seen are based heavily off of the Martians found in the H.G. Wells novel The War of the Worlds.
• The look of the Martian UFO's are based on a design by famed UFOlogist George Adamski, who claimed to have witnessed it firsthand. This style is one of the most iconic of the UFOlogy field and has appeared in many Japanese science Fiction movies and animation.
• Mars People have also appeared in the fighting games Neo Geo Battle Coliseum and SVC Chaos: SNK vs. Capcom. Their fighting moves have been named after paranormal folklore like the Tunguska Blast of 1909 and the 1947 Roswell incident.
• Death animations yield some information about their physiology. They have an inner skeleton (basically just one large skull) and a small mouth. Official artwork shows they also have teeth. They spew green blood, which is acidic and dinsintegrates their body from the inside when they are killed. When severed, their tentacles will spasm momentarily, which implies a nervous system.
• The Metal Slug 2 ending is based off the ending for the Independence Day film (1996) where Russel Casse flies his aircraft into the core of the mothership, charging up for a final attack, causing a chain reaction destroying the flagship.
