Lio is the leader of Mad Burnish, a resistance movement against the experiments on Burnish. To the general public, his resistance is viewed as terrorism. Though he uses his abilities as a Burnish to burn buildings, he always leaves an escape route. He is adamant that Burnish should never kill. He is incredibly passionate about protecting those who cannot protect themselves. He's one of the most powerful Burnish, intelligent, and a reliable leader. However, his passion and abilities also lead to his downfall, as he will rampage due to his pain.
His and Galo's aggressive fighting styles are very compatible.
Lio is of slender build and relatively short stature. He has pale skin, and light green voluminous hair. His eyelashes and eyebrows are the same color. His eyes are pink, though often reflect purple and orange hues.
Lio wears a black leather jacket adorned with military-esque cords and belts. Underneath he wears a long-sleeved white shirt with frilled cuffs and a cravat. He wears a pair of cropped black gloves
His pants resemble sleek biker pants with built-in kneepads and multiple fastening belts. His shoes are black with two buckles.
The armor he creates with Promare is black, sleek, and tall, with stilted blade-like legs. His helmet's visor resembles jagged pointed teeth and ends in two horn-like flairs. In an attempt to appear more intimidating the armor is much taller and well built looking than he actually is.
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. He also appears to emit two horn-like flames from his head, resembling his armor.
Lio is first introduced during the prologue Lio-Hen, where he arrives to save the then lawless Mad Burnish from the Freeze Force. Following their rescue, Lio states that the Mad Burnish's thoughtless attacks are simply making life more difficult for the Burnish and if they go so far as to kill someone the government would crackdown on the Burnish ten-fold. When prompted for what they should do instead, he proposes they build a self-sufficient society away from humans. The former leaders of Mad Burnish agree to his plan and say they will follow him as their new leader.
