He has messy bluish-black hair with green streaks. His eyes fade from green to yellow. He wears a green headscarf (or bandana headband) with two white, yellow-tipped feathers tucked in. He also wears two bone-like dangling earrings. Both of his arms and his neck are intricately tattooed with green ink. He wears decorated black gloves, bracers, and a green jumper tied around his waist. His lower half consists of loose, baggy green pants detailed with blue and orange accents, finished off with tough black boots that feature green, blue, and gold highlights. His Dendro Vision is secured to his right leg, and he uses a Claymore. He is a highly efficient Saurian Hunter. He is straight to the point and evaluates his life and contracts through a highly logical, efficient lens. He sets his prices firmly and operates on the idea that every job has a fair value. He prefers to observe conversations from a distance rather than participate. He rarely complains or gets easily angered, possessing a quiet resilience. While he claims to be bad at comforting others, he steps up to help his friends and allies when they need it most. His calm demeanor is constantly tested by his companion, K'uhul Ajaw. His pragmatic attitude toward money stems from a tragic upbringing in the Scions of the Canopy. He was raised by an abusive, alcoholic father who drove his mother away and eventually fell to his death. Surviving this trauma at a young age is what gives him his serious, no-nonsense outlook on life and drives him to be fiercely independent.

His full name is K'uhul Ajaw. He is a small, 16-bit pixelated chibi-style dragon. He has a yellow head and back, white chest, green spines, and detached yellow hands. His eyes are dark sunglasses with green blinking dots, and he wears a striped yellow and green tail. When angered, his sunglasses enlarge, and his face turns orange-red. His true dragon form is sealed within Kinich's wrist device. In his true state, he becomes a large, intimidating black dragon with green wings and claws, and glowing red eyes. He constantly refers to himself as the Almighty Dragonlord and demands praise and respect, despite being trapped in a wrist device. He's quick to insult everyone he meets, and holds a malicious desire to take over Kinich’s body and freely roam Teyvat. Because his physical form is sealed, his threats are largely toothless. His insults usually earn him a quick flick of the tail, a shove into a box, or a dunk in the water from Kinich. Despite his foolish and annoying outbursts, he is surprisingly clear-minded and highly intelligent in battle.
