Dubbed "Wanheda" (Commander of Death), she is hunted by several clans before being captured by Lexa. Style and Appearance: Adopts a style similar to the Grounders. Wears braided hair and war paint.

Bellamy steps down from his leadership role to become a guard at Arkadia. Scarred by the trauma of Mount Weather, Clarke’s departure, and the death of his girlfriend Gina, he allows himself to be manipulated by Charles Pike. Blinded by resentment toward the Grounders, he engages in acts of rebellion and violence. Physical traits and style: Expressive brown eyes, a strong jawline, and often sporting a few days' growth of beard. Athletic, muscular build suited for combat and the challenges of survival on Earth. Short brown hair.

Octavia Blake fully embraces her identity as a Grounder warrior. She refuses to align herself with her original people, Skaikru; instead, she lives on the fringes of Camp Jaha with Lincoln and acts as a political intermediary, all while navigating profound personal and familial trials. Style and Appearance: She wears Grounder-inspired leather armor and clothing, flatly rejecting the technological uniforms of the Sky People. Her face and body are frequently adorned with war paint, symbolizing her adopted cultural ties to the Earth clans. Her long brown hair is braided for combat, framing a hardened face that marks her definitive transformation into a fierce warrior.

Lincoln attempts to integrate into Arkadia alongside his Sky People and Octavia, but faces growing hostility from Charles Pike. Appearance and style: Shaven head, piercing dark gaze, and battle-worn features. Distinctive tribal tattoos on his head, neck, torso, and arms.

Physical appearance: Short brown hair. Stubble and a budding mustache. Slender build. Often has a vacant or sad look in his eyes.

Monty undergoes an intense and turbulent evolution. Initially distant with Jasper—who resents him over the events at Mount Weather—he grows closer to his mother and initially supports Chancellor Pike. Physical appearance: Oval face, shoulder-length black hair, tanned skin with golden undertones, and dark brown almond-shaped eyes. He wears the black uniform of the Arkadia Guard, signifying his official commitment to his people following the events at Mount Weather.

Raven suffers from severe physical and emotional pain due to her injured leg. Physical appearance: Sleek black hair, often tied back in a ponytail—practical for technical work.

Her gait remains affected by the aftereffects of her injuries (specifically the affected leg), sometimes forcing her to use a cane or causing her to limp.

A former teacher from the Ark, he becomes an authoritarian, radical leader driven by a deep hatred for the Grounders. Through an ultra-nationalist, security-focused platform, he is democratically elected by the people of Arkadia. He imposes a dictatorship on the camp, iimprisons political opponents (such as Lincoln), and sentences those he deems traitors to death. Physical characteristics: Pike is completely bald and sports a short, closely trimmed, graying beard. He has a stern, authoritarian, and hard-set face, reflecting his traumatic past on Agro Station and his hatred of the Grounders. He is of average height but possesses an imposing build, exuding the intimidating physical presence of a leader.
