Height: Early 140s cm. Small in stature but possesses a muscular, toned physique. He has slicked-back hair and sharp eyes, characterized by a strong-willed, constantly grumpy expression. He recorded extremely high standards in all training, including classroom studies, physical ability, and tactical understanding. Porco is talented enough to stand out from the rest, to the point of being confident that his inheritance of the next Titan is guaranteed. He intensely looks down on Reiner at every opportunity, clashing with him frequently. He ruthlessly dismisses Reiner as an incompetent who is only clinging to his candidate status out of pity, and their interactions often escalate into fistfights whenever Reiner talks about his dreams.

Height: Late 150s to early 160s cm. He reigns at the top class in all grades. He commands immense trust as the leader of the operation. Unlike Porco, he does not look down on the underachiever Reiner, instead treating him with kindness and possessing the magnanimity to always look out for those around him.

An intelligent girl with a big-sisterly disposition. Height: Late 130s to early 140s cm. She has outstanding top marks in classroom studies, tactical understanding, and judgment.

Height: Late 160s to early 170s cm. An introverted and inconspicuous boy despite having high potential. His marksmanship skills are far ahead of his peers, and his other physical abilities are also excellent. He is timid, passive, and always hides behind someone else. Because Porco acknowledges Bertholdt's high level of actual skill, he doesn't pick on him as much as he does Reiner. To Bertholdt, the leadership-filled Marcel is a spiritual pillar even more than Reiner is, serving as a reliable older brother figure.

155cm, 65kg. He has the lowest grades among his peers in almost all training, including physical ability, classroom studies, and hand-to-hand combat. He is intensely looked down upon by Porco every day, leading to repeated fistfights. Marcel, Porco's older brother, always protected the often-isolated Reiner and spoke to him kindly; consequently, Reiner truly admires and respects Marcel from the bottom of his heart.

Late 130s to early 140s cm. She possesses unique hand-to-hand combat techniques hammered into her by her father, including joint locks and a focus on kicking. She looks at those around her, who are fired up by their oaths of loyalty to Marley, with cold eyes and has no interest in becoming an Honorary Marleyan. She rarely exchanges words with the hot-blooded Porco. To Porco, she is an enigma whose thoughts are unreadable. Annie also stays a step back, calmly observing Marcel as he acts as the leader everyone relies on.

Late teens. An ace who is already slated to inherit the Beast Titan. His skill and status are worlds apart from the candidates. Warrior Captain. Around this time, he began to demonstrate the power to turn Eldians injected with his spinal fluid into Titans with a single scream and control them at will. He is held in absolute trust.

Warrior Unit Commander. In the Marleyan military, Eldians are heavily discriminated against as descendants of devils, but Magath is the chief official responsible for training these Eldians as Warriors. He is the absolute instructor who holds the power of life and death over Porco, Reiner, and the others. Inwardly, he harbors doubts about Marley's militarism, which treats Eldians as disposable tools.
