human
(Star Wars vs. 40k) Is there any chance that the Empire could defeat the Imperium in an all out war?

It seems to me that the 40K universe doesn't ever lose, so is there a chance for the Galactic Empire to defeat only the Imperium? i feel like it would be a great fight regardless of the victor.

The Imperium's Space Marines would completely devastate the Empire's Stormtroopers. Stormtroopers are clones of Jango Fett, and that's about all they have going for them. Space Marines are something else entirely. Here's a list of the genetic implants that a Space Marine is given in order to become a Space Marine. I've taken it right off the Wikipedia page:

1	Secondary heart -	This simplest and most self-sufficient of implants allows a Space Marine to survive his other heart being damaged or destroyed, and to survive in low oxygen environments. Not just a back-up, the secondary heart can boost the blood-flow around the Space Marine's body.

2	Ossmodula - 	A small, complex, tubular organ, the ossmodula secretes hormones that both affect the ossification of the skeleton and encourages the forming bone growths to absorb ceramic-based chemicals that are laced into the Space Marine's diet. This drastically alters the way a Space Marine's bones grow and develop. Two years after this implant is first put in the subject's long bones will have increased in size and strength (along with most other bones), and the rib cage will have been fused into a solid mass of bulletproof, interlocking plates.

3	Biscopea - 	This small, circular organ is inserted into the chest cavity and releases hormones that vastly increase muscle growth throughout the Space Marine's body. It also serves to form the hormonal basis for many of the later implants.

4	Haemastamen - 	Implanted into the main circulatory system, this tiny implant not only increases the haemoglobin content of the subjects blood, making it more efficient at carrying oxygen around the body and making the subject's blood a bright red, it also serves to monitor and control the actions of the phase 2 and phase 3 implants.

5	Larraman's organ - 	A liver-shaped organ about the size of a golf-ball, this implant is placed within the chest cavity and connected to the circulatory system. It generates and controls 'Larraman cells' which are released into the blood stream if the recipient is wounded. They attach themselves to leucocytes in the blood and are carried to the site of the wound, where upon contact with air they form a near instant patch of scar tissue, sealing any wounds the Space Marine may suffer.

6	Catalepsean node - 	Implanted into the back of the brain, this pea-sized organ influences the circadian rhythms of sleep and the body's response to sleep deprivation. If deprived of sleep, the catalepsean node cuts in. The node allows a Space Marine to sleep and remain awake at the same time by switching off areas of his brain sequentially. This process cannot replace sleep entirely, but increases the Space Marine's survivability by allowing perception of the environment while resting. This means that a Space Marine needs no more than 4 hours of sleep a day, and can potentially go for 2 weeks without any sleep at all.

7	Preomnor - 	This is essentially a pre-stomach that can neutralise otherwise poisonous or indigestible foods. No actual digestion takes place in the preomnor, as it acts as a decontamination chamber placed before the natural stomach in the body's system and can be isolated from the rest of the digestive tract in order to contain particularly troublesome intake.

8	Omophagea - 	This implant allows a Space Marine to 'learn by eating'. It is situated in the spinal cord but is actually part of the brain. Four nerve bundles are implanted connecting the spine and the stomach wall. Able to 'read' or absorb genetic material consumed by the Space Marine, the omophagea transmits the gained information to the Space Marine's brain as a set of memories or experiences. It is the presence of this organ which has led to the various flesh-eating and blood-drinking rituals for which the Astartes are famous, as well as giving names to chapters such as the Blood Drinkers or Flesh Tearers, both Chapters born from the Blood Angels. Over time, mutations in this implant have given some Chapters an unnatural craving for blood or flesh.

9	Multi-lung - 	This additional lung activates when a Space Marine needs to breathe in low-oxygen or poisoned atmospheres, and even water. The natural lungs are closed off by a sphincter muscle associated with the multi-lung and the implanted organ takes over breathing operations. It has highly efficient toxin dispersal systems.

10	Occulobe - 	This implant sits at the base of the brain, and provides hormonal and genetic stimuli which enable a Space Marine's eyes to respond to optic-therapy. This in turn allows the Apothecaries to make adjustments to the growth patterns of the eye and the light-receptive retinal cells - the result being that Space Marines have far superior vision to normal humans, and can see in low-light conditions almost as well as in daylight.

11	Lyman's ear - 	Not only does this implant make a Space Marine immune from dizziness or motion sickness but also allows Space Marines to consciously filter out and enhance certain sounds. The Lyman's Ear completely replaces a Space Marine's original ear. It is externally indistinguishable from a normal human ear.

12	Sus-an membrane - 	Initially implanted above the brain, this membrane eventually merges with the recipient's entire brain. Ineffective without follow-up chemical therapy and training, but with sufficient training a Space Marine can use this implant to enter a state of suspended animation, consciously or as an automatic reaction to extreme trauma, keeping the Space Marine alive for years, even if he has suffered otherwise mortal wounds. Only the appropriate chemical therapy or auto-suggestion can revive a Space Marine from this state. The longest recorded period spent in suspended animation was undertaken by Brother Silas Err of the Dark Angels, who was revived after 567 years.

13	Melanchromic organ - 	This implant controls the amount of melanin in a Space Marine's skin. Exposure to high levels of sunlight will result in the Space Marine's skin darkening to compensate. It also protects the Space Marine from other forms of radiation.

14	Oolitic kidney - 	In conjunction with the secondary heart this implant allows a Space Marine to filter his blood very quickly, rendering him immune to most poisons. This action comes at a price, however, as this emergency detoxification usually renders the Space Marine unconscious while his blood is circulated at high speed. The organ's everyday function is to monitor the entire circulatory system and allow other organs to function effectively.

15	Neuroglottis	 - This enhances a Space Marine's sense of taste to such a high degree that he can identify many common chemicals by taste alone. A Space Marine can even track down his target by taste.

16	Mucranoid - 	This implant allows a Space Marine to sweat a substance that coats the skin and offers resistance to extreme heat and cold and can even provide some protection for the marine in a vacuum. This can only be activated by outside treatment, and is common when Space Marines are expected to be fighting in vacuum.

17	Betcher's gland - 	Consists of two identical glands, implanted either into the lower lip, alongside the salivary glands or into the hard palette. The gland works in a similar way to the poison gland of venomous reptiles by synthesizing and storing deadly poison, which the Space Marines themselves are immune to due to the gland's presence. This allows a Space Marine to spit a blinding contact poison. The poison is also corrosive and can even burn away strong metals given sufficient time.

18	Progenoids - 	There are two of these glands, one situated in the neck and the other within the chest cavity. These glands are vitally important and represent the future of the Chapter, as the only way new gene-seed can be produced is by reproducing it within the bodies of the Space Marines themselves. This is the implant's only purpose. The glands absorb genetic material from the other implanted organs. When they have matured each gland will have developed a single gene-seed corresponding to each of the zygotes which have been implanted into the Space Marine. These take time (5 years in the first case, 10 in the latter) to mature into gene-seed. The gene-seed can then be extracted and used to create more Space Marines.

19	Black carapace - 	The most distinctive implant, it resembles a film of black plastic that is implanted directly beneath the skin of the Space Marine's torso in sheets. It hardens on the outside and sends invasive neural bundles into the Space Marine's body. After the organ has matured the recipient is then fitted with neural sensors and interface points cut into the carapace's surface. This allows a Space Marine to interface directly with his Power Armour.


Due to implant 8, the Omophagea, if the Space Marines kill one Stormtrooper and eat him they'll know everything about every Stormtrooper because they're all clones of the same guy.

Due to implant 16, the Mucranoid, if you manage to blow up an Imperium ship the Space Marines can still push themselves through the vacuum of space, land on the hull of one of the Empire's ships, and then implant 17, Betcher's gland, allows them to spit on the hull and corrode it. Also, when you think you've actually killed a Space Marine it could be that they're in suspended animation due to implant 12, the Sus-an membrane.

The Imperium has this one in the bag.

**TL;DR** - Space Marines would eat one Stormtrooper and understand how they all operate. Space Marines can float through space and spit on Star Destroyers to open their hulls.
