Movie
Description
Bertholdt Fubar is a central figure in the narrative, recognized initially as a quiet and reserved member of the 104th Cadet Corps, where he graduates with the third-highest ranking. His physical appearance is marked by his exceptional height, making him the tallest among his peers, with a slender build, short dark hair, and pale green eyes. This unassuming exterior, however, conceals his true identity as the holder of the Colossal Titan, a power that makes him one of the greatest threats to the civilization within the Walls.

His background reveals that he is not a native of the Walls but an Eldian from the Liberio internment zone in Marley. He was selected as a Marleyan Warrior candidate and inherited the power of the Colossal Titan. Alongside his childhood friends Reiner Braun, Annie Leonhart, and Marcel Galliard, he was dispatched on a mission to infiltrate Paradis Island. The objective was to reclaim the Founding Titan, a mission that began with the catastrophic breach of Wall Maria in the year 845, an act that resulted in immense suffering and the death of Eren Yeager's mother. The traumatic death of Marcel during their journey to the island, sacrificed to save Reiner from a mindless Titan, left a deep and lasting psychological scar on the group.

Bertholdt's personality is defined by a profound internal conflict. He is consistently described as having a weak will, being taciturn, and suffering from low self-esteem. His instructor noted his great potential but utter lack of initiative, and he tends to remain in the background, rarely acting independently. This passive demeanor initially leads others to perceive him as the least emotionally compromised of the infiltrators. However, this facade masks a deeply guilt-ridden and conflicted individual. He is acutely aware of the horror of his actions, and when confronted by his former comrades, the weight of his betrayals becomes evident. He is fiercely loyal to his fellow Warriors, particularly Reiner, for whom he acts as a grounding presence, and Annie, towards whom he harbors romantic feelings. His loyalty is so profound that the mere suggestion of Annie being tortured is enough to drive him into a vengeful rage.

Within the story, Bertholdt serves as a major antagonist following the revelation of his true nature. His role is intrinsically linked to the central mystery of the Titans and the world beyond the Walls. His actions as the Colossal Titan are the catalyst for the entire plot, first destroying the gate of Shiganshina and later breaching the gate of Trost District. For years, he lives a double life, training and bonding with the very people he is destined to betray. His key relationships are complex and tragic. His bond with Reiner is the strongest; they are inseparable, having known each other since childhood, and Bertholdt supports Reiner through his mental fractures. His relationship with his 104th classmates, especially Eren and Armin, is built on genuine camaraderie, which makes his betrayal all the more painful for both sides. Armin Arlert, whom Bertholdt considered a close friend, becomes his primary psychological adversary, using their shared history and knowledge of Annie to manipulate him.

Bertholdt undergoes a significant character development, shifting from a hesitant, guilt-ridden soldier to a more hardened and detached individual. At the Battle of Shiganshina, he sheds much of his former hesitation, resolving to complete his mission with a cold and ruthless efficiency. He rationalizes his terrible actions as an inevitable consequence of a cruel world, not a matter of personal fault. In this state, he declares his intention to kill all his former friends, displaying a chilling indifference that contrasts sharply with his former self. However, this hardened resolve ultimately breaks. Despite his power and determination, he is outmaneuvered by Armin's cunning strategy. After being forcibly extracted from his Titan form, his deep-seated terror of Pure Titans resurfaces. In his final moments, he reverts to a state of desperate, trembling vulnerability, begging for salvation as he is consumed by Armin's Pure Titan, an act that transfers the Colossal Titan's power to his former friend.

Bertholdt's notable abilities are exceptional. As a trainee, he ranked third in his class and was noted for his high skill with vertical maneuvering equipment. However, his true power lies in his Titan Shifting. As the Colossal Titan, he stands approximately 60 meters tall, making him the largest Titan encountered. His Titan form is distinctive, appearing skeletal and lacking skin, constantly emitting jets of scalding hot steam that serve as both a potent defensive mechanism to repel attackers and a means to rapidly dissolve his Titan body. His immense size grants him tremendous physical strength, capable of destroying the fortified gates of the Walls. Despite this power, his Titan form is incredibly slow and lacks agility, making it vulnerable to the swift maneuvers of skilled soldiers. His ability to transform and disappear almost instantaneously, generating a massive cloud of steam, makes him a uniquely elusive and devastating threat.
