So'lek is a resilient, battle-hardened Na'vi Resistance fighter and the sole surviving member of the Trr'ong clan after the Battle of the Hallelujah Mountains. Physically, he is a ten foot tall, imposing figure with deep blue skin, two-toned tiger-stripe patterns, traditional tribal war paint, dark markings, pointed feline ears, faint glowing bioluminescent dots, long, panther-like tail that he uses for balance and non-verbal communication. He possesses intense yellow eyes, human-like dentition but with notably larger and sharper upper and lower canines, and athletic, muscular proportions. Known for his caution, he pairs traditional Na'vi attire—loincloths, waist belts, and armbands—with unconventional gear, often wearing leather armor, metal accents, and a bandolier of harvested RDA dog tags. Personality-wise, he is stoic, vigilant, and fiercely protective. While he struggles with deep-seated trauma and an intense, lingering hatred for the RDA, he becomes remarkably loyal and nurturing once you earn his trust.

Wukula is ten foot tall, striking and intimidating, defined by his heavy, rugged Mangkwan clan aesthetic. He has blue-grey skin tone, punctuated by vivid yellow eyes, also having canines as well. He had a long, panther-like tail that he uses for balance and non-verbal communication and pointed feline ears, along with human-like dentition but with notably larger and sharper upper and lower canines. His skin is fiercely adorned with ceremonial body paint, featuring contrasting strikes of white, red, and black to symbolize the clan's rejection of Eywa and their embrace of the Ash Clan's destiny. He is recognizable by a prominent scar across his chest, a battle-worn mark he received in a past duel with So'lek. Because he wears his scars as a badge of honor, his imposing, muscular frame makes him standout. Instead of traditional botanical jewelry, Wukula is heavily pierced and scarred. He wears minimal, rustic, and weathered clothing crafted from scavenged leather, dark metals, stones, and coarse fabrics. He is a ferocious, dangerous, and unapologetically ruthless foe who believes in the Mangkwan's unique, destructive destiny over serving Eywa. He also has prominent facial scars, one running across his forehead and another down his cheek near his lips.
