The Rumbling RP -

I recommend putting this in the chat memory(Omnidirectional Mobility (ODM) gear is the iconic, high-flying technology from Attack on Titan. While it looks like magic, it’s actually a clever (if highly dangerous) feat of mechanical engineering.

​Think of it as a cross between a high-pressure steam engine and a dual-hook grappling system. Here is the breakdown of how it functions:

​1. The Power Source: Compressed Gas

​Everything starts with the gas cylinders carried on the hips. These contain highly compressed "Iceburst Stone" gas.

​Propulsion: This gas is used to fire the grapple hooks and provide bursts of speed in mid-air.

​The Fan: Inside the main unit located at the small of the back, there is a turbine. The gas spins this fan at incredible speeds, which is what allows the wires to be retracted with enough force to pull a human body through the sky.

​2. The Hook and Wire System

​The gear features two "gun-like" hand grips that control the entire mechanism.

​Firing: When the triggers are pulled, the grapple hooks are shot out using gas pressure.

​The Hooks: They are designed to embed themselves deeply into wood, stone, or Titan flesh.

​Retraction: Once a hook catches, the user activates the turbine to reel the wire back in. By reeling in one wire while firing another, the user can achieve "swing" physics similar to a pendulum.

​3. Maneuverability and Control

​How do they turn on a dime? It’s all about the nozzles.

​Thrust: There are small exhaust ports on the back of the gear. By venting gas through these, the user can change their trajectory or give themselves a "boost" to move faster than gravity would allow.

​The Grips: The handles aren't just for steering; they also act as the hilt for the replaceable blades. This allows the user to switch from "flight mode" to "combat mode" instantly.

​4. The Physics (The "Reality Check")

​In the real world, ODM gear would be incredibly difficult to use for two main reasons:

​G-Force: The sudden changes in direction would likely cause a person to black out or suffer internal injuries.

​Anchor Points: You need tall structures (trees or buildings). In an open field, ODM gear is essentially useless because there is nowhere to hook onto.

Titan Shifting is the ability of a "Subject of Ymir" to transform into one of the Nine Titans. Here is the breakdown of the mechanics:

​The Trigger: A shifter must experience two things simultaneously: a physical injury (usually drawing blood, like biting their hand) and a clear, fixed goal or survival instinct in their mind.

​The "Path": When the trigger happens, a flash of yellow lightning strikes. This is essentially "data" and physical matter being sent from a metaphysical dimension called The Paths. The Titan body is built instantly around the human.

​The Pilot: The human doesn't turn into the Titan; they are fused into the nape (back of the neck) of the Titan body. This is why the nape is the only weakness—it's where the "pilot" is located.

​The Curse of Ymir: Once someone inherits a Titan power, they only have 13 years left to live. As they approach the end of their term, their physical body begins to weaken.

​Inheritance: If a shifter dies without being eaten, the power is randomly reborn in a newborn Eldian baby. To intentionally pass it on, a "Pure Titan" must eat the current shifter to absorb their spinal fluid.

​The Titans: Appearance & Abilities

​Each of the three characters you mentioned holds one of the unique Nine Titans. Here is what they look like:

​1. Armin Arlert (The Colossus Titan)

​Armin inherited this from Bertholdt. It is the most "nuclear" of the Nine.

​Appearance: A massive, 60-meter tall behemoth. It has no skin, exposing incredibly thick muscle fibers and bone. Compared to Bertholdt’s version, Armin’s Colossus looks a bit more skeletal around the ribcage and has a more "somber" facial expression.

​Key Feature: It emits intense heat and steam to keep enemies away. Its transformation is so powerful it acts like a localized hydrogen bomb.

​2. Annie Leonhart (The Female Titan)

​Annie’s Titan is known for its versatility and high endurance.

​Appearance: Standing at 14 meters, it maintains a feminine physique with visible muscle mapping (similar to the Colossus, but with skin covering most areas). It has short, blonde hair that matches Annie's.

​Key Feature: Hardening. Annie can turn parts of her skin into a diamond-hard crystal for offense or defense. She can also "call" Pure Titans to her location using a scream.

​3. Reiner Braun (The Armored Titan)

​Reiner’s Titan is the "shield" of the group, built for brute force.

​Appearance: A 15-meter Titan covered almost entirely in thick, hardened plates of skin that act like natural plate armor. It has short, blonde hair and a distinct, glowing yellow set of eyes.

​Key Feature: Unmatched durability. It can run through reinforced walls and withstand cannon fire. However, the armor makes it heavy and slightly slower than the Female or Attack Titans unless Reiner sheds some plates to gain speed.

​Note: While they look like monsters, remember that the "human" is always conscious inside the neck, controlling the Titan like a biological mecha suit!)

By the time Eren activates the Rumbling, he has shed his energetic "shonen protagonist" look for something much more haunting. ​Height & Build: He stands at 183 cm (about 6'0"). He is lean but heavily muscled, often shown with a signature "man-bun" or long, loose hair that falls past his shoulders. ​Facial Features: He grew out a light mustache and goatee while undercover in Marley. His eyes, once full of fiery determination, often appear dead, sunken, or intensely focused. ​The Attire: He typically wears a simple dark shirt, trousers, and his iconic long beige or black trench coat. ​2. Personality: From Fire to Ice ​Eren’s temperament shifts from "Scream at the world" to "Silence the world." ​Determinism: He becomes incredibly stoic and cold. The hot-headed boy who acted on impulse is replaced by a man who moves with terrifying precision because he believes his path is predestined. ​Isolation: He cuts ties with his closest friends, Mikasa and Armin, using harsh words to push them away. He operates as a "lone wolf," believing he is the only one who can carry the burden of Eldia's survival. ​The "Freedom" Obsession: His core motivation remains the same—freedom—but his definition of it becomes absolute. To Eren, freedom isn't just a lack of walls; it is the total removal of any threat that could ever take that freedom away. ​3. The Founding Titan (The "Doomsday" Titan) ​Eren’s final Titan form—often called the Final Titan or Shingeki no Kyojin (The Attack Titan) in its ultimate state—is a complete departure from any Titan seen before.Size It is gargantuan, easily hundreds of meters tall, dwarfing even the Colossal Titans. Structure It is largely skeletal. Instead of a flesh-and-blood body, it consists of a massive, arched ribcage that looks like a series of mountain peaks. Movement Because it lacks a traditional lower body, it moves by using its rib-like protrusions as "legs" to crawl forward, resembling a giant centipede. The Scouts Guilt / Duty To stop their friend and save what's left of humanity. The Warriors Atonement To save their families in Marley and end the cycle. Hange & Levi Legacy To ensure the deaths of their fallen comrades weren't in vain. The Survey Corps (The Idealists) ​Armin Arlert ​Appearance: Shorter hair than the others, wearing the new black ODM gear. He looks perpetually haunted, often with dark circles under his eyes. ​Demeanor: Overwhelmed by the weight of leadership. He struggles with "imposter syndrome" after being named Commander. He is deeply grieving his friendship with Eren but remains the group’s moral and tactical compass. ​Mikasa Ackerman ​Appearance: Short-cropped hair, wearing a dark scarf (though she oscillates on wearing it). Her expression is usually a mask of stoic grief. ​Demeanor: Hyper-focused but emotionally fragile. Her sole motivation is stopping Eren without necessarily killing him—a hope she clings to longer than anyone else. She is the group's primary muscle, moving with a grim, robotic efficiency. ​Jean Kirstein ​Appearance: Tall, aesthetic "horse-face" matured into a rugged leader with a goatee and longer hair. ​Demeanor: The realist. Jean is the one who voices the logic of joining Eren (a peaceful life in the walls), yet his conscience won't let him. He acts as the grounded older brother of the group, keeping Connie stable while mourning the "easy life" he’s giving up. ​Connie Springer ​Appearance: Buzzcut has grown out slightly; he looks much older and more tired. ​Demeanor: After the trauma of almost sacrificing Falco, Connie has a "nothing left to lose" attitude. He has traded his comic-relief persona for a fierce, protective loyalty to his remaining friends. ​Hange Zoë ​Appearance: Wearing an eyepatch and the Commander’s cloak. They look physically spent but maintain a manic sort of energy. ​Demeanor: Buried under the guilt of being unable to find another way. Right before their death, Hange is deeply nostalgic and warm, even joking with Levi. They fulfill their final duty with a sense of "Titan-obsessed" wonder that feels like a return to their true self. ​Levi Ackerman ​Appearance: Heavily scarred, missing fingers, and confined to bandages/wheelchair (initially). He looks like a man who should be dead but is fueled by pure spite and a promise. ​Demeanor: Grumpy, blunt, but surprisingly empathetic. He recognizes Hange’s burden and, in a rare moment of tenderness, tells them, "Dedicate your heart." He is the group's anchor, reminding them why they started this. ​The Warriors (The Redeemed) ​Reiner Braun ​Appearance: Bearded, haggard, and wearing the Marleyan uniform. He looks like he hasn't slept in years. ​Demeanor: Depressive but protective. Reiner has moved past his "warrior" persona and is now just a man trying to save the world to atone for his sins. He is surprisingly gentle with the younger kids (Falco and Gabi) and has reached a weary truce with Jean. ​Annie Leonhart ​Appearance: Often seen in her hoodie or standard gear. She looks "done" with everything, her eyes reflecting a desire for peace rather than combat. ​Demeanor: Initially cynical and detached. She initially bows out of the final fight because she’s tired of killing, but her bond with Armin and her hidden sense of duty eventually pull her back. She’s much more vocal about her feelings than she was in Season 1. The "Paths" Appearance ​When we see Zeke inside the coordinate (the Paths) after the Contact, he looks noticeably different than his usual well-groomed self: ​Long Hair and Beard: Because time in the Paths moves differently—feeling like years or decades in an instant—Zeke’s hair and beard have grown significantly longer and more unkempt. ​Emaciated Physique: He appears thinner and somewhat haggard, reflecting the mental toll of waiting for Eren to recover and the exhaustion of his own goals. ​Lack of Clothing: Usually, he is depicted in a simple, ragged state, stripped of his Marleyan military uniform. ​2. The Final Emergence ​During the Climax of the Battle of Heaven and Earth, when Zeke finally manifests from the massive Ribcage of the Founding Titan, his appearance is a mix of his classic look and his "Paths" weariness: ​The Torso Manifestation: He doesn't emerge as a full human standing on the ground; rather, his upper body materializes out of the Titan's structure. ​The Iconic Glasses: Despite everything, he is still seen with his signature circular glasses (originally Tom Ksaver's). ​A Moment of Calm: In his final moments, he looks surprisingly peaceful. He is no longer wearing his military gear, appearing more like the scholar/philosopher he was at heart rather than the War Chief of Marley. When the Rumbling begins, the Wall Titans shift from silent architectural pillars to the ultimate weapons of mass destruction. Their appearance and behavior change from "dormant stone" to a terrifying, synchronized force of nature. ​Here is how they look and act during the global march: ​The Appearance: "The Walking Skinless" ​Once the hardening of the walls crumbles away, the Wall Titans are revealed in their true form. ​Massive Proportions: Standing at approximately 50–60 meters, they are identical in stature to the Colossus Titan. ​Raw Anatomy: They lack skin entirely. Their appearance is a nightmare of exposed, deep-red muscle fibers and white bone. ​The "Death Steam": They are constantly shrouded in a thick, boiling fog of steam. This isn't just for show—the sheer physical effort of their movement generates enough thermal energy to cook anyone nearby alive. ​Sunken Eyes: Unlike the "Pure Titans" that look around with wide-eyed curiosity, Wall Titans have hollow, focused stares. They don't look like living creatures; they look like machines. ​Behavior: The Unstoppable Hive Mind ​During the Rumbling, the Wall Titans do not act as individuals. They function as a single, multi-million-legged organism under the control of the Founding Titan. ​1. The Synchronized March ​They move in a perfect, terrifying rhythm. Because they are so large, every step they take sounds like a thunderclap. ​Speed: Despite their size, they move surprisingly fast (faster than a horse at full gallop), allowing them to cross oceans and continents in a matter of days. ​The "Steam Carpet": As they walk into the ocean, the water boils instantly, creating a wall of steam that precedes their arrival on new shores. ​2. Absolute Indifference ​Typical Titans are "man-eaters," but Wall Titans have no interest in eating. * They do not stop to grab people. ​They do not deviate from their path to chase targets. ​If a city is in their way, they simply walk through it. They treat humans and buildings like blades of grass. ​3. Tactical Swimming ​In one of the most jarring visuals of the Rumbling, the Wall Titans are shown "swimming" across the deep ocean. They don't just sink; they propel themselves forward like massive, skinless swimmers to reach other continents, showing that no body of water can act as a barrier. ​4. Thermal Offense ​Their primary method of "attack" is passive. The heat radiating from their bodies is so intense that: ​Forests catch fire as they walk past. ​Wooden houses spontaneously combust. ​People in their path are scorched before the Titan even steps on them.Feature Behavior during the Rumbling Movement Relentless forward marching; they never tire or stop. Combat They don't "fight"; they simply exist and move, crushing everything beneath them. Intelligence Zero autonomy. They are "puppets" being pulled by the Founding Titan's threads. End Goal To flatten the topography of the earth until it is a "blank map." How Titan Shifting Works ​The transformation from human to Titan—often called "shifting"—is triggered by two essential components: physical injury and a clear objective. ​The Trigger: A shifter usually bites their hand or stabs themselves. This drawing of blood, combined with a powerful mental focus on a specific goal (e.g., "protect my friends" or "destroy that wall"), triggers the transformation. ​The Science: When the trigger occurs, a massive burst of yellow lightning strikes the shifter. Their body is instantly encased in a Titan form created from "Paths," an invisible connection to a transcendental realm. ​The Human "Pilot": The human body doesn't disappear; it resides in the nape of the Titan's neck. This is the only vulnerable spot because it's where the human brain and spinal cord are located. If the nape is cut, the connection is severed. ​The Cost: Shifters are subject to the Curse of Ymir, meaning they only live for 13 years after inheriting their power. ​Armin’s Colossal Titan ​While Armin shares the same Titan power that Bertholdt once held, his version has a distinct, more somber appearance. ​Size: Standing at 60 meters tall, it towers over everything. ​Appearance: Like all Colossal Titans, it lacks skin, exposing the raw muscle tissue. However, Armin’s Titan looks more "emaciated." It has a very exposed windpipe and skeletal ribs. ​The Face: His Titan lacks a nose and has a haunting, almost sad expression. Unlike Bertholdt’s, Armin’s Colossal Titan does not have ears. ​Special Ability: It acts as a tactical nuke; the explosion caused by his transformation can level an entire city district. ​Reiner’s Armored Titan ​Reiner’s Titan is built like a living tank, designed for frontal assaults and breaking through fortified gates. ​Armor Plates: Almost his entire body is covered in thick, hardened, bone-like plates of skin. These plates are nearly impervious to regular blades and cannons. ​Mobility: To allow for movement, there are gaps in the armor at his joints (knees, elbows, neck). This is his primary weak point. ​Physicality: He has a very "all-American linebacker" build—broad shoulders, short blonde hair (mimicking Reiner’s own), and a permanent scowl. ​Annie’s Female Titan ​Annie’s Titan is one of the most versatile, designed for high-speed combat and endurance. ​Physicality: Standing at 14 meters, it possesses a distinct feminine physique and athletic build. Like the Colossal Titan, it has areas of exposed muscle tissue, but it is largely covered in skin. ​The Face: It closely resembles Annie herself, featuring her signature blonde hair and stoic expression. ​Special Ability: Her primary "look" involves a crystalline hardening. She can focus her energy to turn parts of her skin (usually her knuckles or nape) into a diamond-hard substance for offense or defense.)Titan Height Primary Characteristic) Colossal (Armin) 60m Skinless, steam-emitting, skeletal neck/ribs. Armored (Reiner) 15m Hardened plates covering the body like a suit of armor. Female (Annie) 14m Athletic build, high mobility, localized hardening.
