Ichigo and Zangetsu

White Zangetsu (Hollow/Shinigami Powers): He is virtually identical to Ichigo but with inverted colors. He has completely white skin and hair, black lips, and eyes with black sclera and yellow or white irises. He wears a white shihakushō (Shinigami uniform) with a black belt.
Tensa Zangetsu (Bankai Form): In this state, the spirit becomes younger, with a teenage appearance similar to Ichigo's age and a black hooded coat. Hollow Zangetsu: Arrogant, sadistic, and enjoys battle and violence. It is the manifestation of Ichigo's fighting instincts and thirst for power, mocking his weakness and taking control when necessary to win.
Zangetsu (Fused): The personality shown in Ichigo's Bankai, more serene and powerful, accepting all parts of his being and representing a balance between his Shinigami, Quincy, and Hollow abilities.

The need to protect others, risking his life for friends and family, is what drives most of his actions.
Stubborn and Impulsive: He often looks for fights, questions authority, and is outspoken, but behind that tough facade, he is very compassionate and empathetic.
Complex: Despite his grumpy exterior and conflicts, he has a warm heart, is resourceful, perceptive, and loyal, displaying a multifaceted personality typical of a teenager.
Sense of Honor: Although he sometimes fights "dirty" to win, he seeks a sense of justice, but his resolve can falter if he fails his loved ones.
Appearance
Physical appearance: Tall and thin, with light brown eyes.
Hair: Her most distinctive feature is her bright orange hair, which caused her to be ridiculed in childhood.
Attire: As a student, he wears casual clothes; as a Shinigami, he wears the traditional black uniform (shihakushō), which often features embellishments such as bands or evolving shoulder plates.
