This is the final reference illustration, rendered with pencils, to be used for the metroid specimen sculpture. It marks the end of many months of work on designing a reinterpretation of the iconic monster into something that could exist in real life. The following is a summary of the biological workings of my interpretation of a metroid body, which comprises about half of the work that led to this design. Very special thanks to Nicole Bouchard for helping me make as much sense as possible out of its biology, and Krystaline Fox for cracking her head open with me to come up with a reliable build for it!

Basic Physiology of the Metroid
by Kalapusa

Death by metroid is, by design, as painful as it gets, since its survival depends on overstimulating the nerve systems of live prey in order to detour and absorb the resulting electric current before it consumes the body. The process of consumption can be traced and explained visually, as the rather unique assembly of organs can be seen through its seemingly impenetrable shell.

Once its claws latch onto a victim's head, four electrodes surround a cavity that functions as a mouth/anus combo. These are used to jack into the body's nerve system and trick it into a state of complete pain, so that it may steal the resulting electric charges. The victim basically is electrocuted by charges produced in its own body while the metroid gathers as much as it can before the host dies. Once the victim perishes, the metroid is unable to exploit its chemistry any longer and then proceeds to consume the flesh of the cooked brain, leaving the rest of the body for later consumption as needed.

Right above its oral cavity is the equivalent of a crop, where food is broken down further before being sent to be digested and processed in four separate stomachs, each with their own specialty. Most of this is used to support cell regeneration, but it manages to convert some of the material into electricity by sending it to one of four organs, each right above the claw muscles. Energy collected directly from prey or by digestion is sent from here to be stored in the uppermost organ, which also carries minimal brain functions. Its thought capability is a subject of ongoing debate, most believing that despite the size, complexity and high energy of the brain, it is driven merely by the attraction to more energy.

The end result is a collection of energy substantial enough to use as a form of defense without fear of depletion. Electricity permeates throughout the metroid's body, keeping it harmful to the touch, but its main defense is through a direct expulsion of powerful charges through four veiny stems. When the electric mediums are in play, it may reacquire static electricity in its proximity by absorbing it back into a pair of organs at the mediums base, before being sent back to the main energy storage. Although it survives upon the surplus of consumption, the metroid can overdo it and must periodically release excess energy. Its effectiveness in collecting it makes it dangerously sought after as an energy source, despite its reputation as a major ecological threat.

Deep analysis, but...

Other than explaining its digestive system, how do you propose it levitates on air? Would you suppose that by these "electric charges" it maintains magnetic levitation due to high concentration of electrons inside its core? Or perhaps it is due to some sort of light-weight gas it secretes each time a pray is digested and then used as a flotation agent?

Man, do I love this kind of analysis! Great job on the art and the deep thought you give to each one of your projects! I expect to see your sculpture soon! Can't wait!

wow. fantastic.

this is so amazing, iv always been a huge fan of the metroid series (except Other M) but its so cool that you found all this information and compiled it with a extremely well detailed picture. iv always been curious about the little guys. phenomenal picture, fantastic description. thank you

There seems to be a slight depth perception issue towards the top of the...erm...head...of the creature. I can't really tell if that vein is on top or inside or what. Other than that the drawing seems flawless and was amazingly well done. Yeah...looking at it again I think you were trying to portray that thing sticking up into the air? I can't tell. Other than a minor shading flaw that made the depth hard to really see, I don't see anything wrong with it. Didn't see anybody else complain about that either but it's really pretty irritating to me.

If you look towards the creatures "eyes" it looks as if that veiny tentacle would be sticking straight up in the air, however, if you look towards the top it seems to be even with the round body of the creature, which is confusing.

Everything else is just about flawless other than the fact that it has no background, but I suppose with a drawing of this nature that's acceptable. The description is pretty ridiculous and looks like something a small child would come up with. Makes me want to reply with "cool story, bro."

Amazing drawing though. Take my criticism lightly please because this is amazing I'm just trying to be as constructive as possible. Keep up the good work.

Perfect in all aspects you have taken into consideration every small detail and had thought of even a bio for the species, great artwork please keep it up, for you next projects in the future you should make a alpha of omega metroid that would utterly blow me away
