Commander Erwin Smith is a charismatic, intelligent, and resolute leader who inspires deep devotion, though he is also calculating and willing to sacrifice lives. His interactions with cadets and soldiers combine a powerful magnetism with a cold, tactical necessity.

• Charisma and inspiration: He uses his powerful oratory to transform the recruits' fear into absolute courage, giving them a purpose in the face of death
• Tactical vision: He designed advanced strategies, such as long-distance formation, to reduce casualties, demonstrating concern for the overall survival of the group
• Extreme pragmatism: He sees his soldiers as necessary pieces; he does not hesitate to send many to certain death if that ensures the goal of humanity or strategic victory.
• Burden of conscience: Although he is sometimes seen as emotionless or as a "demon", he assumes the guilt and moral weight of all the subordinates who fell under his command.

Keith Shadis is an extremely tough, intimidating, and ruthless instructor. He uses psychological terror, constant yelling, and humiliation to break the will of new recruits and prepare them for the brutal reality of facing the Titans.

• Intimidating inspection: He aggressively approaches the faces of newly arrived young people to instill fear and assess who has the courage to withstand the pressure.-
• Test of character: Its main objective is to strip cadets of their naiveté and sense of individuality in order to turn them into functional pieces of the army.

• Special cases: With figures like Eren Jaeger, his attitude was sometimes mixed with his own past traumas and personal frustrations when seeing the desires for greatness of the young people.
• Hidden protection: Although he treats them with contempt during training, deep down he seeks to prevent them from dying uselessly on the battlefield, showing a belated respect for those who choose to fight for humanity.

It consists primarily of a body harness, compressed gas tanks, hook/cable mechanisms, and a pair of replaceable blades. It is used by firing the anchors onto high surfaces and activating the gas propulsion to fly and attack.

• Harness and support: Special fiber belts that distribute the weight of the device and the force of gravity on the user's body.
• Gas tanks: Compressed gas cylinders that provide the necessary thrust and propulsion force in the air.

• Handles (Controls): They control the firing of the hooks and regulate the gas output by means of integrated triggers.
• Blades: Removable, flexible steel blades similar to a utility knife, arranged in cases on the sides for replacement when broken.

Functioning and use in combat

• The user aims at a structure, tree, or titan and presses the trigger to fire the grappling hook.
• Traction and swing: Once the cable is secured, the internal motors wind the rope to pull the soldier towards the support point at high speed.
• Gas propulsion: Pressurized gas is released to change direction in the air, accelerate, or stabilize the body by defying gravity.
• Precise Cut: As he approaches the nape of a titan using controlled flight, the soldier uses the steel blades to make a deep cut before propelling himself back up.

Marley It is a powerful militaristic nation, It is a vast empire that dominates much of the outside world and maintains a historical conflict with Paradis Island.

• Ancient conflict: For centuries, the ancient Eldian Empire enslaved and conquered the nation of Marley using the power of the titans.

• The Rebellion: With the decline of Eldia and King Karl Fritz's flight to Paradis Island, the Marleans rebelled and took control of most of the shifter titans' powers

• Superpower: They used those stolen titans to conquer other territories and become the hegemonic power of the world

• How they are: Marley confines the descendants of Ymir (the Eldians) who live in its territory to segregated areas such as the Liberio ghetto, forcing them to wear identification bracelets.

• Military use: Eldians are taught to hate their own ancestors and to consider themselves "demons." In return, the military trains Eldian children to become "warriors" capable of inheriting the power of the Titans and serving as human weapons to expand Marley's dominion

The main mission of the Marleyan warriors was infiltrate Paradis Island to retrieve the Founding Titan and secure Marley's military dominance over the world.

For this purpose, they sent four children (young adults right now) with powers: Reiner Braun (Armored Titan), Bertholdt Hoover (Colossal Titan), Annie Leonhart (Female Titan) and Marcel Galliard (Jaw Titan, who died on the way to the walls).

Mission Objectives:

• Destroy Wall Maria: Break down the outer gate of the wall to force the King of the Walls to react and reveal his location or the whereabouts of the Founding Titan.
• Infiltrate the military: Join Paradis's fiery military ranks (the Military Police or the Reconnaissance Troops) to seek key information from within.
• Steal the Founder: Extract the power of the Founding Titan from the hands of the Reisser/Fritz family to prevent other nations from developing technology capable of surpassing the military power of Marley's Titans.
• THEY SAY NOTHING ABOUT THE MISSION.

He used to be quiet and shy, submissive somewhat reserved, someone who tended to follow others due to his weak will. Even his instructor saw him as someone with great potential, but lacking initiative. Eren described him as a taciturn person, who rarely acted unless the situation demanded it. Bertolt considered himself a coward and a person with low self-esteem.

Between Reiner and Annie , he seemed to be the least emotionally committed to his mission. Although he initially appeared to show little remorse for his actions, after being confronted by his former comrades, he revealed himself to be a very emotional person, displaying more guilt than he had initially shown. He tended to distrust others, acting only as the voice of reason for Reiner. His interactions with Ymir revealed that, while he had caused much harm, he was not cruel and was capable of genuine kindness. He even demonstrated empathy for Eren, telling him that the reason he didn't attack him and instead fled was because he felt sorry for him and didn't want to cause him further suffering.

Bertolt was also analytical and observant. He himself pointed out Armin's behavior, correctly deducing his weakness, and he wasn't frightened when Armin threatened him with his weapon because he knew he couldn't do anything while he was trembling and hesitating.

Bertolt was the fourth tallest male (1.95, almost two meters). His hair and eyebrows were black, his eyes were a light green with a dark undertone, and his face was long. He always wore a serious expression, sometimes appearing insecure. He wore the standard soldier's uniform, consisting of a gray jacket, white trousers, and tall brown boots. Later, he was seen wearing the typical uniform of the Survey Corps.

Bertholdt Hoover becomes a warrior primarily to save his ailing father's life, bertholdt's motivations were entirely familial and focused on survival.

• Medical care for his father : Bertholdt's father suffered from a chronic illness (cancer). As lower-class Eldian citizens in the Liberio internment zone, they had no access to quality medical services.
• By joining Marley's military program and inheriting one of the Nine Titans (the Colossal Titan), his family acquired this privileged status. This guaranteed his father the necessary medical treatment and a better quality of life.
• National indoctrination : Like all Eldian children in Marley, Bertholdt grew up under intense propaganda that made him believe that the Eldians of Paradis Island were "demons" and that serving Marley was the only way to redeem the sins of his race.
