The Romans, and to a lesser extent, the Greeks, always had one person who had the most power, a Figurehead if you will, nearly every government had this, regardless of what type of government it is.

Julius Ceaser was the Ceaser in Rome and carried much power, but he focused on conquering land so every one was okay with, except the people who killed him.

Chancellor Palpatine was the head of the old republic in it's dying decade, while traditionally the Chancellor has little direct power, Palpatine granted himself emergency powers during the war. Only to serve his own agenda

Darth Vader was the face of the Empire, and while he did wield enormous power, he was really just a pawn to the Emperor.

The Ethereals, over many years, amassed an army of different alien species from sectoids to cyberdisks, they are the ultimate leaders of the cllective, but there are hits of a higher power.

The One Earth government had many high ranking metahumans, from wonder woman to yellow lantern, but all authority was beneath the high counciler, Superman.

The Romans were very skilled in a specific area. Animal warfare. Among all other advancements, this was the most terrifying one. They fed prisoners and criminals to lions, tigers, lampreys, even herbivores like bulls. Anything they could get their hands on. There are many examples of animals being used to incite terror and death in one's enemies.

Head crabs: Terrible creatures from Xen that can wipe out a settlement in a few hours, used by The Combine as a bio weapon against rebels, until it backfired horrendously. these little monsters can latch  onto your head and burrow their 'beak' into your skull, turning you into a zombie under it's control, while you are still alive.

Chryssalid: A nightmarish, insectoid creature, used as a mindless terror weapon by the Ethereal Collective. The are almost impossibly fast, have razor sharp claws and pincers, and turn their victims into zombie hosts for their offspring.

\A Hunter: Origin and species unknown, Can't tell if it is organic or cybernetic, armed with razor sharp fangs, powerful legs that can crush your skull, and energy weaponry implanted on it's head. Used by the combine in order to kill even the most unkill-able of people.


A Xenomorph, the deadliest thing we know of. They were created by some civilization as a bio weapon. That culture is gone, but these remain. You can't hide from it, can't outrun, and is immensely hard to kill, even with high powered weaponry. the deadliest weapon, their 'workers' find a host and implant an embryo, and 48 hours later a full grown Xenomorph violently bursts from the hosts chest.

This week the only new topic that we could conceive was ‘weapon comparison.’ Which is ridiculous given that the romans used medieval weaponry, spears, axes, sword, metal shields, while the cultures I have been researching use far more advanced weaponry, ranging from modern weaponry, Projectile weaponry and gunpowder based grenades, (the UNCS and Xcom), While others use a wide variety of energy weapons ranging from Plasma (The Alien collective,the combine ) to Tibana gas based lasers (The empire, The CIS, The Galactic republic) to Crystal based energy blades (The Jedi, and the Sith). 
Even their armor is vastly difference, The Romans use standard metal armor, which is still a good method, Xcom uses it, the CIS uses it, however, just metal is outmoded now. The Empire and the old republic use a special plastic like polymer for their armor. The Combine and the Ethereal collective use some element that doesn't occur naturally on Earth. The UNSC and the Combine use basic Kevlar and other modern materials. Megacorp use a mix of titanium alloy and nano-technology and electrical currents to redirect damage. Much more complicated than normal metal.

A sword.

A UNSC gunpowder based projectile weapon

A Heavy Plasma rifle, Used by the Ethereal collective and later Xcom

A Tibana gas based blaster rifle. Used by every star wars military.

The Overwatch Standard Issue Pulse Rifle (OSIPR): a dark energy/pulse-powered assault rifle manufactured by the Combine.

Lightsabers. Laser swords based on focusing energy through a lightsaber crystal. naturally comes in blue and green and can be synthetically grown in red.

Greek armor

The MJOLNIR armor, (the Spartan armro) an advanced, and expensive, suit providing protection against everything except drowning.

The phase I armor. Effective and recognizable, with an easy rank  denotation system relying on arm and helmet color, but bulky and uncomfortable.

The Phase II armor, more comfortable and easily modified for specialist troopers.

Storm-trooper armor. Cheap and easy to mass produce.

Basic Xcom body armor, easily obtained, but weak compared to the enemy's. essentially a bottom tier armor for Xcom.

Xcom's top tier armor, A complicated and advanced piece of armor that actually increases one's Psycic abilities, while decreasing the affect of enemy Psi attacks.

Basic Combine soldier armor, relying on thick padding and materials,  Primitive, yet effective

Carbonox armor. The best Megacorp has to offer to a consumer who needs an expensive advanced military grade armor. use thick plating and nano-technology to negate 90% of all damage received, regardless of the source.

So far the Romans seemed to show a typical representative democracy, each region (Planet, State, Universe, Etc,) elected a representative to represent them in a 'Grand council' of sorts, to vote on bill in advantage of their region. A common government type, used in the Galactic republic, The CIS, The Federation and to an extent the Galactic Empire, but underneath the Romans showed a world of deceit and backstabbing. A rotting core hidden underneath a beautiful mask. This is surprisingly common in representative democracies, with the Galactic republic in its final days succumbing to corruption. Some however, like the Empire, Didn't try to hide. They already ruled galaxy, what did it matter?

Recent research has shown that the Romans had a circular population density, meaning that they were most dense in the center in Rome and nearby cities, and consistently getting less dense the further away it was. This form seems like it would very common, but surprisingly, there were not many examples of this, only The Galactic republic, the Galactic Empire and the Federation. But there were few examples of a different population density, some had equal spread, such as the Borg, most had no rigid population chart. However, this is not as much they had a unique population density as it was not enough information. The Combine for example, only have one documented territory, as no one has traveled to their other territories and returned, with the exception of members of the Combine themselves, and they aren't very talkative about this. Others, like free Polaris and the Solana governments have no population density charts that have been released.

The Roman Empire ruled through militaristic strength, which is basically ruling through fear. Literally dozens of governmental bodies have done this, including but not limited to, The Galactic Empire, The Combine, Hydra, The Sinestro core, (literally) The One Earth government, , The Skrulls, the Agorians, Marcone’s Criminal empire, Tachyon’s Empire, Sauron’s Army, The Hutts, Certain areas of the Kree, The Kerchu, the Helghast,  the Covenant, and to an extent, The Blarg and Dreadzone. While this was mainly an excuse to write down a large number of fictional governments, they all rule through fear, like the Roman Empire. However, they don’t all do it like the romans. The Romans mainly relied and having a huge military and using that as its weapon of fear. This was also used by the Galactic Empire, Tachyon’s government, the Blarg, the Skrulls and Dreadzone. Others used Police brutality, like the One Earth government, Sinestro core and the Combine. Some used the fact that they could just make you one day ‘disappear’, namely the Hutts, and Marcone’s criminal empire. Others were just plain bloodthirsty, like the Agorians, The Kree, and Hydra.

Recently I have begun studying the similarities and influences of Greek and Roman culture. so far I have mainly focused on one society. The Old Republic. They are surprisingly similar to ancient Greece and Rome. First, politically, both were representative democracies, focused mainly on senatorial representation, with one main political leader selected from within the senate. Military is a mix between Rome and Greece. They do rely on the method of having large numbers of organized troops, who make up for individual weakness with numbers and organization, namely, clone troopers. However, they also use the Greek method of having a relatively small number of incredibly skilled warrior, such as Spartans, most notably I the republic with the Jedi and certain clone commandos. Actually, almost every military has an 'elite' commando.

An Urk-Hai: a tougher and smarter breed of orc. Were saruman's Shock troops during the 'ring ars'

A Predator: One of the greatest hunters known to anyone, able to hunt anything from a Xenomorph to a Basilisk Leviathan

A Cyberdisc: A advanced and surprisingly organi robotic warrior, armed with advanced energy weaponry, grenade launcher and thich armor makes this one of the toughest and deadliest soldiers in the Ethereal collective
