Two Metroid theories.

Posted by Litbut

Since Metroids canonically have four internal nuclei, I think the nuclei are assigned a mandible, as for the big one, it probably allows them to float and drain energy.

Metroids were designed by the Chozo and drain energy. The X are energy based lifeforms.

So, I think the Chozo designed the Metroid to seek and drain any energy life form they could find, when the Chozo and Metroid weren't part of the human race in physical form or research. But, I do also think they were designed to not drain life forms with a Chozo signature, and that's also why they drain everything they encounter, as far as Samus is concerned, maybe the Chozo didn't think to give her a Chozo signature, hence why the Metroids even go after Samus in the first place, mainly because her Chozo blood doesn't give off or give a complete Chozo signature. What do you think?

Well first of all, the metroids weren't "designed" by anything. Metroids came from the Metroid Queen, who was born by the designers at Nintendo. Afterwards, the space pirates captured and tried to use the metroids as weapons.

Quoting The body of a Metroid consists of a thick gelatinous membrane, resembling a jellyfish, which contains a set of four red, raspberry-like, quadripartite nuclei. They have two pairs of mandibles, one for gripping their prey and the other for extracting its life energy. In early stages of their development, Metroids hover in the air. Metroid Prime 2: Echoes explains that they defy gravity by using kinetic energy that they store in their body. These larval Metroids are the ones most often encountered in the Metroid games.

Metroids are vicious predators with no natural enemies. Once attached to their prey, they are very difficult to dislodge and will otherwise drain their victim completely, killing it. They are known to finish their victims in a matter of seconds. They have an endless appetite and will feed on any and all living creatures they come across (chozo's included), with the single exception of their own species and phazon infused creatures. This immense threat is compounded by their invulnerability to most forms of weaponry. They have only one real weakness: an extreme sensitivity to cold temperatures. Once their membrane is frozen it can be shattered by concussive weaponry (such as missiles), killing the Metroid.

In their natural life cycle (as seen in Metroid II: Return of Samus and the end of Metroid Fusion), Metroids gradually metamorphose to take a somewhat reptilian form, growing a hard organic shell, a head, and limbs. The shell removes their weakness to cold temperatures, but most forms retain a section of weak, uncovered membrane, making them vulnerable to attack. The only known forms with complete shells are the Metroid Queen and Metroid Prime. The egg-laying Metroid Queen appears to be the only form in which Metroids can normally reproduce. As they grow, Metroids also gain the ability to project bolts of static electricity and spit their toxic saliva as attacks.

In Metroid Prime 3: Corruption, it's noted by the Space Pirates that Metroids evolve differently depending on what planet they are exposed to, such as the Hunter Metroids encountered on Tallon IV (Metroid Prime). When mutated by Phazon, Metroids gain various odd qualities. (See Phazon for notes on Phazon-mutated Metroids.) Exposure to beta radiation causes them to asexually reproduce by dividing, much like a cell undergoing mitosis.

The Metroids live on a mysterious energy that they drain from their victims. What this energy is is unknown, as the victim loses no bodily fluid but perishes nonetheless. As of Metroid Prime, this energy is referred to as life energy. Metroids are stated to be energy-based organisms and increase in mass as they drain energy. Metroids can also feed off the energy used by Samus's Power Suit, which will protect Samus herself as long as it is active.

Besides draining life energy from victims, Metroids also have the ability to transfer stored life energy into another lifeform, healing it, as shown in Super Metroid.

Actually, according to the manga, the Chozo designed the Metroid as a final effort to stave off the upcoming X invasion. At their massive evolutionary rate, they would soon become powerful aggressors. Metroids are their antithesis, but before Metroid could be finished, the Space Pirates attacked and unleashed the incomplete version of Metroid. This is the Metroid we know.

And Samus has Chozo DNA in her, so technically she would have a Chozo signature. The Chozo were going to give the Metroid a limiter to attack only the X, but the Space Pirates intervened before this measure was introduced.

be prepared for a wordy post...

What if the Metroids were actually just draining heat from your body? If they have extremely sensitive veins in their fangs, as we'll call them, and the fangs were kept at a frigin temperature due to the powerful heat-absorbing of the veins inside of the fangs, then any time they touched something with the fangs, it would cause immense pain to the prey and a massive amount of heat would be transferred (by the natural laws of science) from the prey to the Metroid's fangs, which in turn would be sucked up instantly by these mysterious veins and sent to the upper half of the Metroid.

Now here's the interesting part: if a Metroid did run on heat, all kinds of things would fall into place. Metroids go for the head, latching onto what is actually the greatest loss of heat in the human body. In 2d Metroid games, they go for the upper half, which is still the most prominent half for heat, since heat rises. That's another thing: heat rises. Metroids are like Jellyfish balloons, no? And they expand and grow as they gain more "energy." So what if that energy actually went into inflating the bubble that is their upper half? And what if that's how they fly, like a hot air balloon? They do seem to drift around. Well if heat is their primary transportation method, wouldn't that mean extreme cold could stop them dead in their tracks? Ahhhh, the true weakness: ice! Metroids kept at lower temperatures seem to be less hostile, a lack of mobility maybe due to deflation?

If cold is the Metroid's true enemy, doesn't it make sense that it's always seeking heat?

EDIT: forgot to mention, this would also explain the lack of markings. As for turning to dust, well, I think the prey would only "freeze" if they were covered in water when this happened.
