Mental's Horde is the name given to the forces that are controlled by Mental. They are incalculable in number and very dangerous, capable of overrunning every planet they attack. However, they generally lack tactics and often just charge into enemy lines of fire, meaning they lose enormous casualties in the process. This does not appear to obstruct them, however.
Mental's Horde is an extremely large army that consists of an unknown number of various species, most likely in the many thousands, which is possibly why Mental always manages to defeat any species he encounters. He also recruits primitive races in order to bolster his ranks; he has created agreements with creatures such as the Aludran Reptiloids, so they can work for them in exchange for magical powers to use on their targets. Mental has even tampered with the evolutionary paths of some creatures so he can mold them into troops for his purpose.
Mental is the last of the Hum-Tah, a race of extremely powerful rulers of large, intergalactic empires. His predecessors had peacefully and wisely ruled the empires, but Mental was different. For some reason, he became dedicated to wiping out all intelligent life. He destroyed the empires, then disappeared for thousands of years. In between these cycles of war, he would lie dormant and deactivate his forces, leaving some behind to detect any sign of intelligent life. When he detected them, he would awaken and activate his forces.
He uses several methods to coerce races into working with him. In the case of the Aludran Reptiliods, he offered them magical combat abilities. In other cases, such as the Zorgs, he simply paid for massive amounts of disposable troops. This isn't to say that Mental has no intelligent creatures working with and for him, however. Ugh-Zan III and Ugh-Zan IV appear to be intelligent enough to be considered as Generals in Mental's army, and Mordekai the Summoner was able to properly use and research magic.
Other than deploying troops onto planets such as Earth with the use of Alcor Class Warships, Mental is able to teleport his forces directly to any desired location, whether it be in Cairo, on an island, or deep underneath the Great Pyramid. Mental will usually teleport and deploy his forces in order to stop Sam whenever he is near his objective.
Not only is Mental capable of teleporting his forces at a specific location, he can also teleport them back onto a warship. An instance of this is when Sam fights a warship in Cairo. After defeating the warship, any troops that survived the battle are immediately teleported back onto the warship.
As part of his scheme to wipe out intelligent life, Mental and his alien horde stop at nothing short of genocide in order to maintain control.
An instance of this is when Mental discovered the Ellian species, who had came across the remains of the old empires once ruled by the Hum-Tah and pieced together who Mental was. Before they could do anything, Mental returned and destroyed them, then disappeared soon afterwards.
Mental's armies on EarthEdit
The Mental WarEdit
- Main article: Mental War
During the 22nd century, Mental discovered Earth, and, as the planet harbored intelligent life, he deployed hundreds of Alcor Class Warships, each carrying hundreds of thousands of vicious alien creatures, as part of his scheme to wipe out the human race. This lead to a three-year conquest that had driven humanity almost to the point of extinction.
In a last-ditch effort, the world leaders turned to their last chance: the Time-Lock, a recently excavated device supposedly capable of granting a single person the ability of time travel via an inter-dimensional portal. Through it, that person could reach a pivotal point in time and alter events of the past. But as the device laid dormant, they had to first discover a means to activate it.
During the conflict humanity took massive casualties, though the exact number of this is unknown. It's possible that, due to military forces having lost or struggled to fight off against the invaders, the deaths were in the many millions. During the final stages of the war, it's clear that humanity had lost. Most or all of the inhabitants of Cairo had been wiped out by Mental, and it seems that all that was left was a small group of Earth Defense Force soldiers posted somewhat near Cairo. The humans had placed their last hope on the Time Lock, which was something that Mental seemed to be unaware of.
Many propaganda posters could be found throughout Cairo and other settlements throughout Egypt, so that Mental's forces assured their influence on Earth and remind its residents of their presence, as well as tempting surviving humans to join their cause. There were two varieties of posters, one features a Beheaded Kamikaze, while the second one showed a Gnaar.
Mental shows no remorse towards the human race, and sends its alien hordes to eliminate any intelligent life that stands in his way. Of course, the human military forces fought back against the alien invaders and tried to repel their attacks. But, they were no match against Mental's superior technology and the sheer number of his forces, and were eventually overrun by them.
As a result of the heavy casualties that humanity suffered, many cities became abandoned and there were little to no signs of life. Abandoned cars and other vehicles littered the streets, many houses and other buildings had been destroyed or reduced to rubble by the warships' scorcher beams, and the numerous supplies of ammunition and armor, as well as barricades in Cairo indicated that the city had recently become under siege by Mental's forces.
Finishing off humanityEditDuring Sam's journey to power up the Time Lock, Mental staged a final attack on the Earth Defense Force's headquarters, completely wiping it out. Now that the last bit of resistance had been taken out, Mental prepared to finish off humanity once and for all, by hurtling the Moon into the Earth. In this timeline, Mental managed to finish off humanity, just like all the other species that encountered him.
Mental utilizes both technology and magic in order to achieve his goals. The diversity can be seen in his army, where he uses cyborgs, executed enemy soldiers raised from the dead, reanimated skeletons of long extinct races, trained war animals, clones, creatures made out of pure magic, robots, mercenaries, or even plain vehicles.
For instance, when Mental found the Aludran Reptiloids, a race of four-armed reptilian creatures from the Aludran system, they agreed to join his army, and in return, gave them magical powers that allows them to conjure homing projectiles from their hands.
To bolster his ranks even further, Mental has gone as far as to tamper with the evolution of certain species, such as the Fiendian Reptiloid Demon. These creatures were once simple, lizard-like organisms from Fiendia Prime, until Mental found them and crossbred as well as mutated them through several generations, until they were reinforced with a titanium skeleton, which increased their endurance, thus making them formidable opponents.
Mental's hordes consists of all kinds of creatures, including cyborgs, soldiers or mercenaries, vehicles, creatures made out of magic, and many more.
The majority of Mental's forces are made up of soldiers or light units. They are often equipped with advanced weaponry, such as laser or plasma rifles and other standard-issue firearms, while some are not very intelligent or organized.

Most of the cybernetic or robotic creatures that are part of Mental's forces have gone through extensive artificial or manufacturing processes, or were grown as biological mechanisms in Mental's bio-tanks. Some of these organisms have had their genome programmed to give them biologically grown mechanical parts.
- Cucurbito the Pumpkin: A genetically engineered humanoid wearing overalls, uses a chainsaw and has a pumpkin for a head.

He was the first great prototype of Mental's Necromechanoid Project, and was created from sewn-together parts of massive beasts, such as Highlander Aludran Reptiloids. Inheriting the resilience of these corpses, Raahloom is incredibly tough and most standard weapons can barely make a scratch on his body,

- Tank Bio-mechanoid: A mixture of leftovers from a Sirian slaughterhouse, a caterpillar mount, and Plasma Cannons for hands. The mount allows it to travel on many types of terrain, making it useful for many different types of environments.
- The General: Modified Bull Soldiers that have a Tank Bio-mechanoid's lower body. This combines the Bull Soldier's rocket launchers with the Tank Bio-mechanoid's maneuverability, which makes it a deadly foe.
- Tyrannosaurus: A large, blue mechanical Tyrannosaurus-like enemy that is similar in appearance to the T-Mech. Its only attack is to launch missiles at the player.
Creatures and wildlifeEdit

- Cerebull: A bull-like creature that will charge towards its target and ram into them with their horns.
- Devil Stallion: A strange creature that is a mixture of DNA of horses and Aludran Reptiloids. Being a hybrid, the Reptiloid DNA within the Devil Stallion's genes enables it to breathe fire, making it quite powerful. In addition, it was given a pair of wings in order to fly. To top it off, Mental's researchers gave it an undying loyalty to Mental and cast some black magic on it in order to make it more resistant to enemy attacks.
- Evil Ferdinand: A variant of the Sirian Werebull that is black in color and behaves similar to the normal variant, though he is stronger and leaves a trail of fire behind.
- Flying Kleer: This type of Kleer is basically a winged Kleer skeleton armed with a blunderbuss.

- Gnaar Baby: Smaller and weaker version of the Gnaar.
- Hatchling Antaresian Spider: A newborn Antaresian spider. As they are hatchlings, their jaws and exoskeleton are underdeveloped, thus they can be killed easily by squishing them under one's foot. They can bite at close range, or fire balls of acid from glands in their tails from a distance. Alone they are not a threat, but a pack of them can be dangerous.
- Heliopora: Large creature that fires laser beams from the sides of its body.

- Hound: Small creature with horns that rams into its target.
- Hopper: Frog-like creature that bounces towards its target to attack.
- Juvenile Antaresian Spider: Larger and more dangerous than the hatchlings, a juvenile already has developed jaws and exoskeleton, and are more resilient to gunfire than the hatchlings. As they are much bigger in compassion, they can't be stomped on, but it is possible to rip their carapace apart, which kills the juvenile instantly.
- Juvenile Sirian Werebull: A small and weaker variant of the Sirian Werebull, though they are genetically programmed with the same ferocity and temperament as their normal counterparts.
- Killer Plant: A hostile cactus that will fire a rocket at the target. It does not move.
- Kleer Skeleton: An undead skeleton of a being from an extinct race from the planet Kleer, of Alpha Canis Majoris. They will charge towards their target, and leap out to attack with their sharp claws. At closer range, they will repeatedly slash at them. From further distances, Kleers can conjure twin chainballs one after another in a single direction towards the target.
- Lizard: A strange green creature often found swarming in packs and spawn from eggs that are thrown from sewer pipes or fall from trees. Sometimes they can also be hiding in crates. They will bite at the target if they get too close.
- Marsh Hopper: A small, greenish frog-like alien originating from the planet Rigil Kentaurus. They are social creatures, and live in large groups, but have a suicidal instinct to protect their territory. In all-devastating havoc, they will attempt to leap at an enemy and explode by over inflating themselves. Upon exploding, toxic slime from within their intestines splashes the target.
- Mental's Pet Hamster: A large, hamster-like creature with multiple eyes. It has three pairs of legs and a segmented body which resembles that of a caterpillar.

- Queen Hopper: Large frog-like creature that leaps into its target to attack. Can also spawn Toad Hoppers from its body to aid in the fight.
- Reeban Electro-Fish: An aquatic animal from the planet Reeb. When it spots an enemy, it fires a bolt of electricity from the light attached to its head. The bolt will disorient the enemy upon contact. This makes the Electro-Fish very dangerous in groups, as a constant barrage of lightning will constantly disorient the enemy, making it difficult for the victim to fight back.
- Reeban Tooth Fish: Like the Reeban Electro-Fish, these creatures are from the planet Reeb, though they can only bite their target instead of using electrical attacks.
- Sandwhale: A very large, aggressive territorial creature. It is unknown how they were transported to Earth or if they are even associated with Mental's horde, but it is suspected that they were accidentally brought to Earth in microscopic larvae state from a desert planet in Gamma Pegasi. They appear to mostly feed on sediments or minerals, though if its territory is disturbed, they are able to swallow a heavy assault tank whole, without chewing. These creatures are so well protected by their thick scales that there are no known ways to kill one short of nuclear weapons.
- Shielder: Strange creature encased in a shell. It will damage the target if it comes into contact with the Shielder.
- Sirian Werebull: The Sirian Werebull behaves much like an ordinary bull. It is a strange mixture of Sirian and cattle DNA. Its two attacks consist of ramming the target, or if they are not fast enough, it will attempt to gore the target with its horns, causing more damage than a ram would.
- Slug: A slug-like creature that uses two 'hands' to move around. Its only attack is to get close to the target and melee them.

- Toad Hopper: Small creatures spawned by the Queen Hopper.
- Tooth Fish: Water creature that chases after the target and bites them.
- Vertigo: Large red creature that spins and fires projectiles at the same time.
- Vuvuzelator: A strange living pile of pancakes that has forks for legs and vuvuzelas sticking out of it. When it gets close to the target, it will begin playing loud music, which hurts the target as long as it is within its music radius. When its health has been reduced to 0, it will start playing its vuvuzelas and play them at a higher pitch until it explodes.
- ZumZum: A large hornet-like creature. It has two attacks: spawning ZumZum Jr.s and shooting projectiles at the target. It will also charge at the target to try and sting them.
