Fuegoleon Vermillion

Fuegoleon is a tall man with purple eyes and long, straight vermillion hair. His hair is neatly combed to the back while leaving his long fringe combed to the left in a wavy hairstyle. One of his notable features is the red markings around his eyes. Another one is a diamond-shaped mark of similar color on the center of his forehead. Additionally, he also wears a pair of red earrings. During his fight with Licht, Fuegoleon loses his right arm, and it is later replaced by one made of fire.

Fuegoleon's attire consists of a white tunic which is covered by a dark blue shirt with long sleeves and high collar. The shirt is decorated with gold-colored fabric with vertical stripes design on its edges, collars, and along the sleeves. In order to keep the shirt together, he wears a purple sash around his waist. Moreover, he wears white trousers and black high boots with similar design as his shirt. On top of his attire, he wears a long red cape.

As a member of the Crimson Lion squad, Fuegoleon wears the squad's signature robe that only covers his torso. His squad robe has similar color as his personal robe. The robe has gold intricate designs at the lower front edge and complemented with a scarf of similar red color. Additionally, a pair of gold-colored ropes are protruding from between the scarf and the robe at the front and a purple stone is decorating each end. Lastly, the squad's insignia is located at the center back of the robe.

Six months after the elves' attack, Fuegoleon wears a similar high-collared shirt but with a clover pattern on the left side of his chest. A leather belt holds the shirt closed more, and his grimoire pouch hangs off the left. His squad robe has scalloped edges and gold trim; the trim along the bottom forms clovers.

As a boy, Fuegoleon has short hair and wears a dark, short-sleeved shirt with a light-colored design along the edges and up the sleeves.

Fuegoleon is a fair person that judges people from their true worth rather than their social status. This side of him is seen when he is defending Asta from the House Silva's oppression by reasoning with them that Asta was brought by Julius Novachrono, which means that the Wizard King has acknowledged his worth. Furthermore, his act also shows his view of justice where he would not stand and stay silent when someone is being oppressed regardless of the reason or the status of the perpetrator.

Fuegoleon has also been shown to have a charismatic personality that translates to his leadership ability. He is able to quickly take charge of a situation and deploy orders accordingly, such as giving several Knights orders after shortly being informed that the Royal Capital is being invaded. Fuegoleon is also very calm and collected in dire situations. He is capable of analyzing and finds his opponent's weaknesses, even while defending against a barrage of attacks.

Moreover, Fuegoleon is a wise man with a no-nonsense mentality where he would immediately scold anyone that loses focus in an important situation. His wisdom can be seen when he is willing to consult Noelle Silva after she was humiliated by her siblings, regardless of her reputation within the noble community.

Lastly, as a noble, Fuegoleon is still a prideful man where he could easily be angered by the slightest hint of impoliteness, such as when Nozel Silva is giving him a condescending remark and when he admits to himself that Yami was more perceptive than him when it came to Asta.
