Rebel Infantry: Present throughout the entire series, excluding Metal Slug 5. General Morden's loyal troops are equipped with rifles, pistols, knives, machetes, grenades, bazookas, mines, drop shots, rockets and fire crackers. In graphical terms, they have more sprites and variations than other enemies. We can encounter with them in many aspects: from the future, in space, on water, or can even be prisoners.

Those are some soldiers of the Rebel Army. Here they demonstrate a few of their attacks:


Some soldiers that have been captured or otherwise incapacitated:

Frosty rebel141

The Amadeus Infantry. (only appears in the Final Mission of Metal Slug 4):


The Future Rebels. (only in Metal Slug 7/XX)


The Ptolemaic Army. (only in Metal Slug 5):


Allen O'Neil: Known as "The Immortal" of the Rebel Army. He's the most powerful of all soldiers in battle. He usually attack you from the ground, but also can attack you from the air. Equipped with a M60 Heavy Machine Gun, grenades and a knife, he can be a real nightmare.


There are also some other characters based on O'Neil:

Allen O'Neil Jr: The son that follows the example of his father in Metal Slug Advance.


O'Neil Robot: An android impersonator of O'Neil. Only in Metal Slug 4.


Sword-Wielders: This type of enemy covers many units with different traits and many sources, but they all have 2 things in common: They use swords as their main weapon, and have their unique attacks for each group. These are the Arabians, the Pirates, and the Hunters.

Arabians: (عرب) Seen in Metal Slug 2 and Metal Slug X. They are allies of the Rebel Army. Some fight on foot and strike quickly while others ride camels and others throw swords.

Pirates: Seen in Metal Slug 4. They work indepently and attack a civilian cargo ship. Some carry guns.

Mummies: From Ancient Egypt come the walking corpses known as mummies. Like the zombies, they were disturbed during excavations by the Rebel Army and now rise. In Metal Slug 4, the Rebel Army controls the curse and uses it to turn the amusement park staff into mummies. They are basic slow-moving mummies, present in Metal Slug 2, Metal Slug X, Metal Slug 3 and Metal Slug 4 (When you take the underground path). Come in a few varieties:

Regular: Most common and less dangerous. Their only attack is a poisonous breath move that transforms you into a mummy. If you are already "cursed" and they breathe on you again, you'll die. Of the 3 types, those are the easiest because their attacks are short and they walk slowly, making them easy enough to avoid.


Drop shot: Distinguished from the previous type by its colour (this mummy seems to be off-white, while the previous kind is beige), they rarely move, and their only attack is to drop a cursed orb that turns you into a mummy. Be careful when they appear in groups.


Scarab-spewing: The most difficult mummy to fight. It is in a greenish colour and like the previous one, usually doesn't walk. The danger is in its attacks: The scarab they spits up will follow you continually until you destroy it, and will cause instant death upon contact. Even if you destroy the mummy, the locust will still follow you.


Dog: A variation of the basic mummy design. Dog-mummies are similar to beige mummies, except that they move faster and jump as well. Their attack consists in a "cursed" bark with the same effect as the beige mummy's breath.


Bats aren't technically mummies, but they can also transform you into a mummy. They appear in Metal Slug 2, Metal Slug X, and Metal Slug 3. Bats carry around a tar containing a cursed liquid that they will dump on you to turn you into a mummy. The bats from Metal Slug 3 will kill you upon contact. There is also another more peaceful type of bat present in Metal Slug 2, X, 3, 5, 6 and 7/XX that rarely attacks and doesn't carry any jar. Some of them are golden coloured and give points to the player if picked up.


One of the people of the haunted house that comes out in Metal Slug 4. It is just a human which will only pretend to attack you. If you attack him, the human will stop acting like a mummy and shiver in fear. But when the real mummies attacks him, he will also become hostile and attack you. Only appears in Metal Slug 4.


Mutated Soldiers: An experiment created by Rebel Army, possibly on war prisoners. They are mutated creatures that can crawl quickly on the floor and walls. They attack by exploding when near the player. They appear in Metal Slug 2 and Metal Slug X. Very similar to the Hopper Mechas.


Martians: Also known like "Mars People", are cephalopod-likes alien invaders who ally with the Rebel Army (they provide some of their technology for the creation of a small number of Rebel machines and weapons). They appear in Metal Slug 2, Metal Slug XMetal Slug 3Metal Slug 6 and Metal Slug XX. There are 3 different kinds based on color and weapons:

Gray: The normal infantry of martians.

Brown: One level up. They are more dangerous than grey martians, also more damage resistant.

Mars people (cafe)Mars people cafe (disparando)

White: The highest rank martians. Their advanced attacks in addition with their high damage resistance makes them very dangerous. However, they are seen only a few times, and not in large groups.

They are also present in mini-UFO's that fire single laser shots. The black UFO is more powerful and resistant than grey UFO. Only grey martians and brown martians drive it. 


Another type of UFO that doesn't need a driver to fly and attack. They are very fast in their moves and attacks, but they usually fly away after the attack. These UFO's are seen only in Metal Slug 3Metal Slug 6 and Metal Slug XX.


Note: You can see mini-UFOs in some levels of Metal Slug 1, Metal Slug 2, Metal Slug 3, Metal Slug X, and Metal Slug 6. Just watch the sky. Also one of them appears as a cameo during the final credits of Metal Slug 7/XX.

Chowmein-Conga: Large mutated crabs that appear in Dr. Moreau's Island and in an underground cave full of mutated bugs. They attack with toxic bubbles and their pincers. Only appear in Metal Slug 3.

It needs to charge up before shooting, warning the player of the incoming attack with the flashing red light above it. This one also appears in Metal Slug 3 and Metal Slug 7/XX.


Man Eater: Another experiment of Rebel Army. Moving predatory plant that eats the player. They will sometimes turn into a taller plant that will spit out a seed. The seed will either kill the player on contact or hit the ground and grow into another Man Eater.   Maneater020
