| ~ In-game Description |
Behavior
- Arachyu's are solitary and aggressive creatures with a similar temperament to a mantis shrimp.
- Their claws can be used to launch their body forward and crush targets between them with 8,500 pounds per square inch of pressure.
- They have average intelligence but are capable of mapping out attacks. Additionally, they can see millions of colors beyond a human's sight capacity.
- Arachyu are peculiar parents in that they let their babies latch onto their backs, similar to spiders. After 3-5 weeks, young Arachyu will venture out independently.
- They can tolerate fresh water but prefer salt or brackish water. Arachyu are mostly seen in deep, warm waters.
- In combat situations, they refuse to fight other heavily armored creatures but are fine with fighting anything else.
- They are very solitary, and spend most of their lives alone. They are also territorial and will claim an area to themselves and protect it, only stopping for brief periods in their lives to bring up younger Arachyu.
- Their hunting style resembles that of an ambusher, often using their impressive shell to their advantage while whipping out incredible bashing attacks that often send opponents into a daze or even unconscious. They are brutal fighters and will aim to crush and break their target's skull for the kill. Arachyu are capable of holding their prey up with their many limbs while using their claws to feed.
Artist Headcanon
- Their claws are extremely tough, and their exoskeleton protects them from the force of their own attacks.
- They grow by shedding their exoskeleton in smaller sections at a time. This process is very hard to notice and can last infinitely, as there is no set limit for how long and large they can grow.
- Arachyu's shell will create another layer for babies to latch onto to protect their mother from their claws.
- Arachyu can boost themselves by launching backward with their claws in a manner similar to crawfish or lobsters. Additionally, they can maneuver backward with quick swipes of their tail.
Appearance
The Arachyu shares a resemblance to the mantis shrimp, decapod crustaceans like the pistol shrimp, and lobsters. Its body consists of distinct segments: an ovoid-like, unfused cephalon (head) housing the jaw, two pairs of antennae (one above and one below the jaw), and two eyes. Its unfused thorax contains seven pairs of partially visible gills and two pairs of pereiopods (walking legs). Additionally, it has a slim, six-segment abdomen adorned with six pairs of pleopods (swimming legs) that culminate in a leafy-like tail fan. The first pair of pereiopods have evolved into chelipeds (pincers), while the other two are smaller raptorial appendages that serve as maxillipeds (feeding assistants). The first three pairs of pleopods are highly developed for swimming, while the last three appear to be vestigial and less functional.
The Arachyu's entire body is covered with armor-like plates and spikes, featuring various shades of ombré faded green-blue and a spotted pattern.
Males
Males have four round, curved growths on either side of the middle of their tail.
Females
Females have four spines coming from the bottom of their "neck".
Abilities
Main Article: Creature Abilities
This section is intended to list and describe the abilities of the Arachyu. (editor list)
- Ambush is a recode-only ability, inheritor of the Ambush control in Legacy, and thus shares some similarities to it. Ambush can be toggled by pressing (not holding) the correct active ability key (which may vary between creatures). It will automatically deactivate after a set period of time, after stamina runs out, or after halting movement, whichever happens first. Like legacy ambush, recode Ambush ability allows a temporary speed boost according to an ambush multiplier inherent to the species (e.g. x 1.5 or x 1.25), usually granting a faster Sprint (except when the multiplier is x1.0 or lower). It will not be stopped by entering or leaving water once initiated; but at a higher stamina cost and a possible decrease in turn speed, directly making a creature unable to turn while ambushing. Similar to legacy, a creature can know if ambush is toggled not only from the the evident speed boost while moving, but because when pressing the activation button, the camera FOV zooms out a tiny bit. Ambush can be used while sprinting. However, unlike Legacy ambush, pressing the appropriate key again will not stack max time and stamina consumption, and can be initiated underwater by creatures with the appropriate mobility type (however, it still keeps the Legacy characteristic of keeping creatures not adapted to water from initiating ambush underwater). Additionally, Ambushing disrupts strafing.
- Bleed Block/Block Bleed is a passive ability that grants the creature resistance to getting bleed status from melee attacks at the very least, and every other source at most. Recode's equivalent of bleed defense; it is percentage based, e.g. if an attacker deals 5 bleed per hit and the receiver has 60% bleed defense, then the receiver gets only 2 of that 5 bleed.
- If a creature's Block Bleed is 100%, then they are immune to Bleed inflicted by melee direct attacks once fully grown. This ability is gained gradually as the creature ages, that is, a creature with 100% Block Bleed will have some fraction of bleed defense while growing, being such fraction bigger as it grows.
- A negative value in-game may indicate an extra vulnerability to the status effect this ability is supposed to protect from.
- Dart is an active ability of the special control Jump/Dart/Glide/Flight, similar to ambush in terms of being a temporary speed boost that propels the creature forward, but restricted to water and usually far less stamina-consuming. All creatures capable of jump and with the proper semi-aquatic mobility type can dart when underwater. A creature cannot dart while strafing nor outside water, but a dart will become a jump if the impulse propels the creature outside water.
- Dart has an associated speed boost and stamina consumption for every creature. If there's not enough stamina, the creature cannot dart.
- Grab is an active ability, the recode's equivalent of Legacy's creature "grab a lighter creature", allowing a creature to pick up a lower-tiered creature. Unlike legacy's, it has several pecularities, among them that grabbing is no longer based on weight, but tier. Another peculiarity is that grabbed creatures cannot escape until 5 seconds later. After that, the grabbed creature can struggle by using any button and will release such creature from the grab. The user can ungrab at any moment by pressing the same button used to grab. A creature darting from outside water will grab any creature it finds automatically. Interestingly enough, using this ability may also make a piece of grabbed food drop.
- Harden is an active ability which decreases movement speed by 20% in trade of a 35% increase in weight and 25% increase in health regeneration. Does not affect turning rate or turning speed.
- Injury Attack is an ability that offensively deals injury status when biting. A negative value means that it heals an amount of such status upon biting.

Trivia
- Concept by Undeary in the Creatures of Sonaria Discord.
- Arachyu is the fourth creature inspired by crustaceans, following Polymonstrum, Militrua, and Kavouradis.
- Arachyu was originally intended to be semi-aquatic, which can be seen in its concept art. However, according to East, "...due to tester input and issues regarding its body type, it was decided that [Arachyu would] be more enjoyable as a full aquatic instead."
- Animations by Nimwit.
- Arachyu is sometimes called "lobster" or "blue lobster" by the community.
- The name "blue lobster" is also a reference to a popular meme.
- The Arachyu originally had the highest raw damage output for a Tier 4 until it got updated to a Tier 5 in the December 24th, 2022 update.
- Now, Arachyu is the second Tier 5 aquatic in-game, the first being the Syroudon.
