Porco Galliard, nicknamed Pock, was an Eldian Warrior from Marley's Liberio Internment Zone. He appeared as a young man of medium height and slender build, with gray eyes and blond hair styled in an undercut, typically wearing military attire and the mandatory Eldian armband. He was the younger brother of Marcel Galliard. Years before the Paradis Island Operation, Porco was a leading candidate for the Armored Titan. During Warrior selection, he openly criticized Reiner Braun as untalented and motivated only by a desire for Marleyan approval, punching him in an altercation stopped by Marcel. Porco continued mocking Reiner. In 843, when Reiner received the Armored Titan instead of him and Marcel inherited the Jaw Titan, Porco angrily confronted Reiner but was forced to apologize by Marcel. He remained on the continental mainland when the Warriors departed for Paradis. After the Warriors' return in 850, Ymir—who had consumed Marcel and gained the Jaw Titan—surrendered. Marley transformed Porco into a Pure Titan to consume Ymir, granting him the Jaw Titan. Through Ymir's memories, he learned her history and motives but gained no insight into Marcel's experiences or death, deepening his resentment toward Reiner, whom he blamed. Porco's Jaw Titan possessed a muscular build, an armored face, fingers, and knuckles, with deep-set eyes, a heavy brow, and long blond hair. Cog-like hardened skin replaced its lips, and it typically moved on all fours. Its primary strength was its powerful jaws, capable of shredding metal and stone. During the Fort Slava battle four years later, Porco initially remained on standby due to anti-Titan artillery. After Gabi Braun disabled an armored train carrying the artillery, he transformed, shielding Gabi and Falco Grice from machine gun fire. He then breached enemy defenses, destroyed railways, and eliminated anti-Titan cannons to protect the deployed Armored Titan. He coldly dismissed Reiner's gratitude afterward, stating his actions preserved Marley's military asset. Personality-wise, Porco displayed combat bravery but harbored bitter arrogance, especially toward Reiner. He excessively trusted his Titan abilities, leading to shock when confronted by the Survey Corps' tactics. Despite his abrasiveness, he deeply cared for fellow Warriors, reacting with panic and rage when Pieck or Zeke were endangered. This loyalty and impulsiveness often led to recklessness, like charging Eren Yeager in fury upon learning of Bertholdt Hoover's death. At the Liberio festival, Porco and Pieck were lured into confinement by a disguised Marleyan soldier, preventing transformation. After escaping with the Panzer Unit's aid, he joined the battle against Eren's Attack Titan. Ambushing Eren's Titan from behind, he attempted to bite through its nape but was thwarted when Mikasa Ackerman severed his jaw muscles. Amid the chaos, he witnessed Zeke's apparent defeat and Armin Arlert's emerging Colossal Titan, fueling his rage-driven assault. In his final moments, while used to break the crystal protecting Lara Tybur, Porco accessed Marcel's memories. He learned Marcel manipulated the Warrior selection to ensure Porco inherited the Jaw Titan, recognizing his brother's lifelong protection. Accepting this, Porco declared his superiority over Reiner before sacrificing himself to save Falco, allowing Falco to inherit the Jaw Titan.
