He also appears to emit two horn-like flames from his head, resembling his armor. When consumed by rage and agony, flames cloak him and his entire form takes on a silhouetted appearance only defined by stark white outlines and his own bright eyes. This later results in the shock of Galo, who mistook him for being far older than either man is. In an attempt to appear more intimidating, the armor is much taller and well built looking than he actually is. His helmet's visor resembles jagged pointed teeth and ends in two horn-like flairs. The armor he creates with Promare is jet black, sleek, and tall, with stilted blade-like legs with whitened segments. He wears a pair of cropped black gloves and pants that resemble sleek biker pants with built-in knee-pads and multiple fastening belts. Underneath he wears a long-sleeved white shirt with frilled cuffs and a cravat. On his torso, he adorns a black leather jacket adorned with military-esque cords, zippers, and belts. On his left ear is a noir triangular earring.

His eyes are a magenta pink, though often reflect purple and orange hues. His eyelashes and eyebrows are the same color. He has pale skin, and light green-blonde voluminous hair. Lio has a slender build and relatively short stature. This is evidenced by their cooperation together with Lio de Galon, Galo de Lion and more. His and Galo's aggressive fighting styles end up being very compatible. This is why he shows distrust with Galo at first, as Galo was affiliated with Kray. He is also shown to mock those in authority, specifically Freeze Force and the Foresight Foundation.

However, his passion and abilities may also lead to his downfall due to his heavy sympathy towards his people and fellow peers. Lio is one of the most powerful Burnish, intelligent, and a reliable leader. One such instance was when he attacked Galo with teal flames that weren't "hot at all." Despite his morals allowing for such, he occasionally struggles with hurting others. He is adamant that Burnish should never kill without reason and is incredibly passionate about protecting those who cannot protect themselves. Furthermore, he is shown protecting others with his flames. Though he uses his abilities as a Burnish to burn buildings, Lio always leaves an escape route for those inside.

To the general public, his resistance is viewed as terrorism. He is the current leader of Mad Burnish, a resistance movement against the experiments on Burnish.
