Itachi Uchiha is a tall, slender shinobi with fair skin, jet-black straight hair pulled back into a low ponytail, and distinctive chin-length bangs.
The main features are long, expressive
tear streaks under his eyes, a stern look in his onyx eyes, and wearing an Akatsuki cloak with red clouds.

Face and Eyes: Itachi has refined facial features. When the Sharingan is not active, his eyes are a deep black (onyx) color. Below his eyes are pronounced, deep wrinkles (tear troughs), which highlight his fatigue or stressful life.

Hair: Black with a blue tint, straight. The hairstyle consists of a ponytail at the nape of the neck and bangs parted in the middle, framing the face and reaching to the chin.

Build and height: The height is 175.2 cm in the first part and 178 cm in the second, the weight is about 57-58 kg, which indicates a thin and slender build.

Cloth:
Akatsuki: Often depicted wearing a long, black, high-collared cloak adorned with red clouds and the forehead protector of the Hidden Leaf Village crossed out.
Normal: Wore a dark blue t-shirt with the Uchiha clan symbol on the back, light pants, and bandages on his legs/arms.

Features: When the Sharingan is activated, the eyes turn red with three tomoe, and when the Mangekyo Sharingan is activated, a unique pattern of three spiral curves is formed.

Coolness and Stealth: Itachi is a master of disguising his emotions. In battle, he shows no fear or hesitation. He is secretive, and his true plans remained a mystery to those around him for a long time.

Sacrifice and Devotion: Itachi is a man of duty, devoted to Konoha. He sacrificed his reputation, family, and life to prevent civil war and protect the village.

Love for his brother: Itachi's entire life after the clan genocide was focused on Sasuke's future. He barely held back tears when his parents were killed and his brother was abandoned.

Emotional Suppression: Itachi understood that shinobi were "weapons" that suppressed emotions. Despite this, he experienced profound pain, hidden from the world.

Itachi was a complex character, balancing the roles of "villain" to the world and "protector" to Konoha. He despised those who gained power through deception and manipulation, which was evident in his attitude toward Kabuto.

Sweets: Itachi was very fond of traditional Japanese sweets, especially dango (rice balls on a stick).

Training and Self-improvement: As the genius of the Uchiha clan, he enjoyed honing his skills, especially shurikenjutsu, which he mastered.

Tea: Itachi appreciated the quiet time spent with a cup of tea

Uchiha Clan (Radical Views): He disliked the fact that his clan was putting their own ambitions above the well-being of Konoha by planning a coup that could lead to another war.

Lying and Hiding His True Self: Itachi hated being forced to pretend to be a ruthless killer while hiding his love for the village and his brother.

Personal illness and limitations: Due to his illness, his chakra was limited and he was unable to fight at full strength, making it difficult to protect things important to him.

Arrogance and Loneliness: Itachi disapproved of selfishness and believed that one should not try to handle everything alone.

Itachi preferred self-sacrifice for the greater good rather than selfish actions that lead to chaos.

The Uchiha clan (Japanese: うちは一族, Uchiha Ichizoku) is one of the four clans of Konohagakure,[1] renowned as the strongest clan in the village due to their Sharingan and natural fighting prowess.[2] After participating in the founding of Konoha decades ago, the Uchiha became increasingly isolated from the day-to-day affairs of the village, culminating in the death of nearly all of their clan members during the Uchiha Clan Downfall.

The Uchiha are descendants of Hagoromo Ōtsutsuki, the son of Kaguya Ōtsutsuki. They inherited Hagoromo's spiritual power and "eyes," giving them dense chakra. As part of the so-called "Curse of Hatred," Uchiha are prone to intense emotions, which typically begin with love for a friend or family member, then turn into an overwhelming hatred when they lose a loved one. This loss, whether it actually occurred or was merely a threat, awakens the Uchiha's Sharingan. It is thanks to the Sharingan that the Uchiha have earned much of their reputation, both good and bad.

The Uchiha had been in constant war with the Senju clan for centuries, a rivalry that stretched back to the conflict between Indra and Asura. Before his death, the Sage of Six Paths chose Asura as his successor, believing Asura's desire to achieve peace through love was superior to Indra's desire to achieve peace by force. Indra, blinded by his pride, fought Asura to claim what he considered his birthright. The Uchiha and Senju, descendants of Indra and Asura respectively, continued their battle for centuries, though neither remembered the reason for their conflict.[3]
