One of the many things I find funny and irritating is the slant of a lot of interpretations of Alecto's name (that it's about feminine rage)--on this here wlw internet in the year of our lord 2024, it's easily made to figure as rage against God, or rage against patriarchy, or religious oppression, and therefore an allusion to the idea that she's going to get her vengeance on John for betraying and oppressing her somehow, but like

John is the one who named her Alecto. He's the one who named her that. So, naming her "Alecto" is alluding to the embodiment of John's rage--their rage, since they are joined inseparably (John even explicitly says that when he first perceives her: "You wouldn't stop screaming. You were so scared. You were so goddamn mad").

He says of Alecto to Harrow, "In a very real way, you are [Alecto's] children". At a very surface level, Alecto is (depending on the text or tradition), one of the Furies--famously, in several surviving Greek tragedies, who punish Orestes for the crime of killing his mother. In fact, in Aeschylus' Oresteia, they declare that they are specifically bound to avenge matricide.

So the name "Alecto" alludes to the nature of John's mission and how he sees it.

It also implies that his divine rage, the rage that gives him power, the power that makes him divine, that he either represents or wants to represent, is feminine rage. He was chosen by Earth (which, Furies are sometimes the daughters of Gaia); he is her champion, however he's managed to fuck that up. Once the truth of that comes out, it becomes clear that all of his power comes from her.

And that's why you get statements from Tamsyn Muir like:

“[T]he God of the Locked Tomb IS a man; he IS the Father and the Teacher; it’s an inherently masc role played by someone who has an uneasy relationship himself to playing a Biblical patriarch. John falls back on hierarchies and roles because they’re familiar even when he’s struggling not to. Even he identifies himself as the God who became man and the man who became God. But the divine in the Locked Tomb is essentially feminine on multiple axes – I think Nona will illuminate that a little bit more."

So yes, he plays the role of Emperor and God and Teacher, with all of the things that implies. And I don't think it should be discounted. But he also is (and partly sees himself as) the chosen champion of a goddess, or what is for all intents & purposes for a human like him a goddess. He is her avenger, and while she sleeps, her avatar.

And I don't think we're meant to read him purely as a parasite who's taking advantage of her to gain power for himself, either. Or an oppressive, Kronos-like figure. Especially if you consider Palamedes' theory of the Grand Lysis, even if he was purely motivated by desire for power before (which I really doubt), there are parts of each in the other, now. What was clear and separate before is uncertain and interpenetrated. Is his rage his own, or hers? Is his mission of revenge his, or hers? If he wants power, is that his own selfishness, or her desire to survive?

And does it matter?

God I fucking hate Olaf the snowman so fucking much holy shit. Holy shit, every frame he's in, every scene, every gif, every jpeg, he's got this painfully vacant, stupid as shit, fuckass look on his stupid lumpy face. Absolutely no part of his ugly as sin piece of shit character design is endearing. His stupid fucking legs? Who the hell makes a snowman with legs. His dumb flaily fucking twig arms? His shitty, lumpy bastard head? The three thousand percent unnecessary dumbass shitass fucking SNOW BUCK TOOTH that no snowman has EVER FUCKING HAD IN tHE HISTORY OF GOD'S GREEN FUCKING EARTH? God, I hate him. I hate him so much. So FUCKING much. Every time I see a stuffed toy Olaf or an Olaf gif or a shitty goddamn commercial, it ignites my primal rage response and I'm overcome by the need to punt this shitty little homunculus into the fucking sun. "Bhurr blur, I'm Olaf the fuckshit snow fucker, I like warm hugs". Fuck you. Fuck you fuck you fuck you fuck you fuck you. You look like Tow Mater summoned a patronus. Your dumb fucking twig hair makes your whole shitty head look like a hairy skin tag. I hate your dumb fucking lumpy carrot nose and your stupid, empty googly eyes and your over-the-top goofy ass upbeat asshole personality. Any scene he's sad it invokes all the wrath and fury of a spoiled child having a meltdown over a chocolate bar in a w*lmart checkout line. And I know its irrational. That's the worst part. I know he's just a shitty fucking side character in a stupid fucking children's movie, I know it doesn't matter, I know I shouldn't care. But that's part of the problem. The part where no matter the might and fury of my hatred, the locus of my homicidal intent is alltogether inconsequential. I find myself laying awake in the dark in the early hours of the morning consumed by the spirit of Wrath itself, all the force and might of a flaming hurricane directed at a bottle of piss in a ditch by the highway. The absurdity of it all burns me to my core. What better things could this energy be directed towards? And yet my disdain for this stupid, useless, insubstantial failure of endearing character design utterly eclipses the intrigue of all other pursuits. I hate him. I hate him on a level of my mind reserved for the worst of the world's array of sinners, and I can't even begin to justify it. Shitstick the snow dick is, for all intents and purposes, the animated corpse of all of humanity's saccharine pretenses- every condescending, passive-aggressive statement of meaningless upper middle class suburban drama distilled into a single, hateable form. The fucking. Fuck. I have no words. There is no cuss or epithet in any language that can encapsulate the height of the emotions I am experiencing. God, I hate him so much. I hate him so, so fucking much. I want to light his ugly little dumpster body on fire. I want to graphically beat him to death with his own stupid fucking nose. I want to punch him to death. You know that weird feeling you get, when you see a picture of something so cute you find yourself overcome with the bizarre, inexplicable urge to squeeze it? It's EXACTLY like that, except instead of cuteness it's disgust. The wordless knowledge that his existence as a fictional work is evidence of all the failures of mankind. I find myself possessed by the will of a Holy Angel gone rogue with the belief that God has made a mistake, and I alone must correct it. This is the trial by which Samael himself fell from grace. This wild, meaningless rage. A thousand blades of shining steel cast with inhuman force in the direction of a plastic grocery bag floating on a breeze. What horrors must I have committed in a past life to be plagued by this torment now? I must Unmake this fictional snowman

[the-fallen-blue]

I've been seeing a lot of discourse about the Murderbot casting, to the tune of "Wells says she imagined it as brown"/"the narrator of the audiobook is a man"/"the writing just sounds female, the types of things it notices and cares to mention and the way it puts its sentences together is how a woman would"/"it's canonically agender wtf"/"agender people can look masculine you asshole"/"it's supposed to look big and average that means white male"/"that's your own cultural bias in play and evidence says the average in its universe is brown"/"that's your bias in play there's no ironclad indication what the average is in the Corporation Rim"/"here's every single canon description of Murderbot it has no canon physical attributes other than Tall it could be played by literally anyone Checkmate Atheists" etc etc etc and it all just... misses the point?

No one is annoyed with Skarsgård!MB because "white dude" isn't canon.

They're annoyed because written Murderbot presents a level of identification and recognition for them that "white dude" does not.

Or, in other words: it is difficult to imagine a level of abuse more profound than not having the freedom of your own literal thoughts, consigned to a cripplingly limited and cruel social role from which any deviation is met with brutal pain. And it is all too easy to imagine a demographic who are presumed violent, hostile, and inferior, good only for labor and violence, who must be controlled and denied and unpersoned for the good of the rest. The lines aren't hard to draw, here; Murderbot is deeply relatable to many people who are not (visibly masculine) white men, specifically because they are not (visibly masculine) white men. Because they share with it the experience of oppression, marginalization, and being known on sight as wrong, being punished for the slightest deviance. Because it is not just another in the long boring line of ten thousand thousand grizzled white space marine heroman types; it is the thematic opposite of that.

And yeah duh obviously you can look like a boilerplate white dude and still suffer plenty of oppression, but film is a visual medium. Character design is a crucial part of its language, especially when a specific character is the only example of its type available to the audience. It is a shorthand that the audience will understand as a reflection on the wider setting. Which means that casting Skarsgård is, whether they meant it or not, a subtle statement that the ultimate bigotry in Murderbot's universe is against and about conventional white dudes.

Or in other other words, you cannot refute complaints about Skarsgård!MB with ~canon~ because canon has nothing to do with it. It's a thematic inconsistency, a failure to understand the not the story's text, but its subtext and its place in the wider cultural conversation of sci-fi (or at least to accurately translate those meta considerations to the satisfaction of a decent segment of the audience).

Like you can still yell about how bullshit you think that is if you want. Casting's not that deep or it's an important queer metaphor to pass and still struggle or people have no inherent 'right' to representation or whatever else. I'm not telling anyone what to say or believe. But just understand that that's what you're actually arguing with (or for, for that matter), is all I'm saying.

Some notes for this time around!! I played around a lot more this time with poses and zooming in and out and I'm honestly super proud of how it turned out :DDD Coloring took a long while so it might not be feasible to continue doing this amount of rendering for every comic I do,,, but we'll see, I'll continue to experiment with it I guess

I tried my best this time around to use the color blue sparingly to show Tage's shift in personality from generally warm and amicable to just cold and ruthless when fighting. You can see that blue thaw out a little with the victory pose he does and when Ace checks if he's injured. Also the colors for Ace's little reminiscing panel are borrowed from the 1015 luffy/roger dream segment because I always think of it when I think about the three of them as kids...... the colors of the sunrise,,,

I also for some reason had Such A Clear Image of how I wanted the beat up marines to look. One of those very nice moments when what you envision lines up well with what you end up drawing haha

I think I forgot to draw sabo's ponytail more often than I forgot to draw his neck scars this time,,,

Wet Beast Wednesday: sea urchins

As I continue the slow grind of covering every living group of echinoderms for this series, it was inevitable that I would eventually encounter the only echinoderm I've actually studied. Sea urchins are among the most iconic of marine invertebrates, but many people just think of them as part of the scenery. I'm here to show you that there's more to these creatures than just being spiny lumps on a rock.

(Image: a purple sea urchin (Strongylocentrotus purpuratus) being held in someone's hand. It is a round, globular animal with a dark purple color. Light purple spines emerge from it all over its body, with the longest being around the middle. End ID)

(image: a long-spined sea urchin (Diadema savignyi). It is a black sea urchin with spines longer than its diameter. End ID)

Urchin is an old-fashioned word for hedgehog, and sea hedgehog is a fitting name for these round, spiny animals. Sea urchins tend to be fairly small, with a diameter of 3 - 10 cm (1 - 4 in), though some species have very long spines that make them seem larger. The main body of an urchin is round and enclosed in a (usually) hard shell called a test made of calcium carbonate. The test is covered with a slayer of skin and muscle that controls the spines and small, pincer-like structures called pedicellaria. Within the test are the internal organs. As with other echinoderms, sea urchins are radially symmetrical as adults, with five segments arranged around the center like pizza slices. The two main body holes are found on the top and bottom of the animals where the segments converge. At the bottom is the mouth and at the top is the anus. Each segment also has a hole near the anus used to release gametes and one will have a larger pore called the madreporite, which is used to control the amount of water within the urchin's body. The mouth is a unique structure known as Aristotle's lantern, consisting of five tooth-like structures (one for each body segment) that interlock together and sharpen themselves. Behind the teeth is a rasping tongue.

(image: a close-up of an urchin's mouth, showing the Aristotle's lantern. It is a hole surrounded by a fleshy lip. Five spade-shaped teeth are emerging from the edge of the hole. End ID)

Internally, most of the body is taken up by the digestive tract and water vascular system. The digestive system lacks a stomach, with the esophagus attaching directly to the small intestine. The digestive tract forms a loop as it passes through the body. The water vascular system uses seawater to form hydrostatic pressure that moves the tube feet. All starfish, urchins, and sea cucumbers have tube feet, small, transparent, tentacle-like structures they use for movement. Tube feet are hollow and retracted into pores on the skin normally. To be used, they have to be inflated with water, which makes them stick out of the body, where they can be controlled with muscles. Tube feet end in suction cups that can be used to grab into structures around them. Seawater drawn in through the madreporite serves as the source of pressure needed for the tube feet to function. In urchins, tube feet cover the body and are used for locomotion, moving food to the mouth, and moving objects on or off the body. The main body cavity is filled with circulatory fluid that uses special cells to move oxygen and nutrients around the body. The nervous system is simple, consisting of a central nerve ring around the esophagus that branches into nerves that connect to the rest of the body. Urchins have no eyes (except for the family Diadematidae, which have eyespots), but are sensitive to light. The gonads are usually small, but during mating season they can swell to fill much of the body cavity.

(Image: a drawn diagram showing a cross-section of a sea urchin, with the different organs and body parts labeled. End ID. Source)

Sea urchins are found in oceans worldwide, from intertidal zones to the deep sea and the tropics to the poles. They are bottom-dwellers who feed primarily on algae, which they scrape up with their teeth. However, they will also take a variety of food, including carrion, aquatic plants, and other slow-moving or sessile animals like sponges, polyps, bivalves, worms, and sea cucumbers. Urchins can play a key role in regulating algae populations through their ecosystems, but they also rely on predators to keep from overeating necessary algae. Famously, California's kelp forests were almost destroyed by urchins eating the kelp after their primary predator, sea otters, were driven to near extinction. Urchin's primary defense against predators is their hard tests and spines. As most of the edible portion of the urchin is within the test, predators have to get through both layers of defense first. The spines are hollow and each can be moved independently of each other, allowing them to be positioned toward a threat. Many species contain venom within their spines as an added layer of defense. This venom is rarely dangerous to humans, but can cause swelling and painful reactions. Another layer of defense is the pedicellaria, which are good at removing small animals and parasites from the skin. The flower urchin, Toxopneustes pileolus, has modified its pedicellaria into flower-like structures that extend beyond the spines and can deliver a sting that can be fatal to humans.

(Image: a flower urchin. It is a pinkish urchin covered with flower-like structures that extend to the length of the spines. It has placed some bits of shells on top of it. End ID)

Sea urchins possess distinct males and females, though the differences are internal, making it impossible to tell which is which based on visual examination. During mating seasons, the gonads swell as they generate gametes. Urchins tend to reproduce in groups at synchronized times (possibly correlated with the phases of the moon in shallow-water species) to maximize the possibility of fertilization. When ready to mate, the gametes are squeezed to empty their contents through the genital pores and into the water column. Sperm must find egg in the water to fertilize it. Most sea urchins provide no parental care, but in some species, the female will retain the eggs in her spines to protect them. The eggs hatch into bilaterally symmetrical larvae called plutei that drift with the plankton. As they develop, a section of the larvae will develop into a radially symmetrical adult rudiment. This piece will eventually break off and become the juvenile urchin while the rest of the larva dies. Because echinoderms start out as bilaterally symmetrical larvae, we can infer that they developed from bilaterally symmetrical ancestors and the radial symmetry of adults is a more recent development.

(image: a series of photos showing the embryological development of a sea urchin from a single cell to a cluster of cells, to a bell-like structure, to growing several arms, to the eventual adult developing and breaking off. End ID. Source)

Fossils show that the oldest sea urchins had large, club-like spines that they walked on, with the modern spines being a later development. Most of those urchins died out with the dinosaurs, leaving the pencil urchins of order Cicaroida as the only living members. All other living urchins are Part of the clade Euechinoidea. Amongst them, there are still some oddballs, known as the irregular urchins of clade Irregularia. These urchins have moved away from radial symmetry, with less symmetrical segments and the anus and mouth moving from being on the top and bottom to being on the sides in the heart urchins. Heart urchins have gone from bilateral symmetry to radial symmetry and are now going back to bilateral symmetry. Heart urchin mouths don't have an Aristotle's lantern. Instead, they use strands of mucus to capture food and cilia to pull the strands back inside. Sand dollars, also known as sea cookies or sea biscuits, are also in this clade. These are flattened urchins with short and very fin spines that resemble velvet. They are burrowers who spend much of their time buried under sand and as such are rarely seen alive. The name sand dollar comes from their tests, which are similar to old dollar coins and can often be found washed up on beaches. While still radially symmetrical, sand dollars also have a secondary form of bilateral symmetry, with a distinct front and back end that often look different. Irregular sea urchins also tend to have fewer gonads and associated pores than regular sea urchins.

(image: a red pencil urchin (Heterocentrotus mamillatus) nestled among coral. Instead of spines, it has a series of long, thick, red clubs. End ID)

(image: a purple heart urchin (Spatangus purpureus). It is an urchin elongated on one direction and with a few rows of long spines amongst short ones. On the surface facing the camera is a large hole that could be the mouth or the anus. End ID)

(image: a group of irregular sand dollars (Dendraster excentricus) partially buried in the sand. They are round, flat animals with a velvety covering of tiny spines. The are sticking out of the sand. End ID)

Sea urchins have been known to humans for as long as people have lived near the ocean. Stings can occur when people step on them and can cause pain and irritation, but are rarely medically significant. That being said, some people can have allergies to the venom, which could be a big problem. Spines left in the wound should be removed, as they can continue injecting venom. Urchins are a food source for people around the world, specifically the gonads, which are the only meaty part of the animal. The gonads are often marketed as roe or corals and can be eaten raw or cooked. Urchins are also used as a model organism in embryology due to the interesting and well-studied nature of their larval development. Urchins are vulnerable to pollution, habitat loss, and over-predation. Ocean acidification due to climate change poses a major threat to them, as it reduces the quality of their tests.

(image: tow sea urchins served as food. They are upside-down with the bottoms removed. The gonads are visible within as five orange, spongy structures that take up most of the body cavity. End ID)
