Leonard Burns is an imposing figure with a muscular build, wavy grey hair partially bound in a ponytail, a chin-strap beard, and piercing green eyes. A black eye-patch covers his severely burned right eye, which flares with ember-like intensity when his pyrokinetic abilities activate. His attire features a protective jacket fastened with cross-shaped buttons, a crisp white collared shirt, dark trousers, and boots marked with Company 1 insignias. Born on August 10, Leonard exhibited devout religious fervor from childhood, later granted the epithet “The Lion That Banishes All Evil” by Raffles III. As a young liaison bridging the Holy Sol Temple’s public and covert branches, he mentored Five-Two in the Netherworld until an Infernal outbreak in the Amaterasu forged an Adolla Link between them. This connection exposed both to the Evangelist’s influence, damaging their eyes and eroding Leonard’s faith in the Temple—though he continued prayers despite growing skepticism toward the Sun God. In Year 186, Leonard intervened in the Kusakabe house fire, confronting a Demon Infernal clutching Shō. The Evangelist’s interference triggered uncontrollable combustion in his right eye. After rescuing Shinra, he deceived him about his family’s fate to dissuade the boy from joining the Fire Soldiers. This pivotal event spurred Leonard’s covert inquiries into the church’s obscured history, including Raffles I’s enigmatic transformation preceding the Temple’s founding. As Company 1’s Captain, Leonard enforced a doctrine of strength and duty, often concealing vital truths to shield others. His combat centered on hand-to-hand mastery and the Ignition Ability Voltage Nova, which amplified physical traits through controlled internal combustion. The ability’s escalating stages heightened heat emission, durability, and destructive force; at advanced tiers, his aura deflected assaults, and strikes cratered concrete or repelled plasma attacks. His dynamic with Shinra shifted from mentor to adversary. During training, he effortlessly overpowered Shinra and Arthur Boyle, underscoring his creed of supremacy. Later, he confessed his deception after clashing decisively with Shinra, acknowledging the youth’s growth. Exploited by Haumea’s manipulation of his wavering faith, Leonard allied with the White-Clad, enabling Akitaru Ōbi’s capture. Their confrontation peaked when Shinra’s Adolla-enhanced speed outpaced his Voltage Nova: Stage Five. Defeated, Leonard was impaled by his Adolla-born doppelgänger. Merging with it preserved his consciousness but twisted him into a demonic entity. Declared dead by the Tokyo Empire, he reemerged to assist Joker against rival doppelgängers. Post-Great Cataclysm, Shinra’s reality-warping power restored Leonard’s original form. Grappling with fractured faith, Leonard upheld his priestly role despite disillusionment, prioritizing institutional stability over personal ethics. His physical endurance, strategic secrecy, and duty-bound resolve defined his trajectory from protector to antagonist, culminating in a begrudging recognition of humanity’s imperative to evolve.
