Description
Prince Lars Ul Metallicana rules the kingdom of Metallicana as older brother to Sheila Metallicana. Standing 186 cm tall and weighing 66 kg, he shares identical physical traits with his sister. His personality is defined by bravery and fearlessness, exemplified when he defied the forces of heaven alongside the Sorcerer Shoguns despite expecting death. Lars maintains a brash, blunt rivalry with Dark Schneider, tempered by mutual respect forged in their battle fifteen years prior to the series.

Fifteen years before the main story, Lars fought Dark Schneider during the latter's near-global conquest. Facing defeat, Lars summoned the 500-meter mechanical Dragon Knight Proto I—originally crafted by Europa's Ten Wise Men to combat the god Anthrasax—and fused with it. This fusion amplified his spiritual energy, enabling him to kill Dark Schneider. However, using the Dragon Knight against a target other than Anthrasax incurred an extradimensional curse. His soul separated from his body, trapped as a light-blue baby dragon, while his physical form remained imprisoned within the Dragon Knight. His disappearance was widely mistaken for death.

As a dragon, Lars sought a Dragon Knight successor. Ninja Master Gara of the Four Heavenly Kings discovered and kept him as a pet. Despite their past enmity, Lars observed the resurrected Dark Schneider, who remained uniquely able to understand him in this form. The curse broke when Anthrasax destroyed the Dragon Knight just before Dark Schneider could merge with it, expelling Lars' original body and restoring his humanity. He later revealed to allies like Geo that the Dragon Knight was not a holy artifact but the source of his curse.

During the Battle for the Ark at King Crimson Glory, Lars fought genocidal angels using his dragon warrior powers. He stood as the last defender after the Sorcerer Shoguns and Samurai fell, ultimately slain by higher-ranked angels. The Adam of Light later revived him, leading Lars to recognize it as the Messiah and identify Kall-Su as the prophet Elijah—a revelation he conveyed to the dwarf king.

Lars possesses dragon blood granting immense strength rivaling Dark Schneider. His primary weapon is the holy sword Heavy Metal, capable of destroying angels. Key techniques include Bisecting Rupture (a bisecting sword strike), Dragon Mode (amplifying draconic energy), Dragonic Magnum (dragon-energy projectiles lethal to higher beings), and Instant Death Earth and Sky Hell and Heaven Strike (his angel-destroying ultimate technique). His most potent ability, One Hundred Times Dragon Mode, multiplies his power a hundredfold by channeling inner dragon energy.

Trivia notes: His birthday is September 24th, commemorating the Battle of Shiroyama. His name references Metallica drummer Lars Ulrich. He is the only core character from the manga's first part whose original human form never appeared in any anime adaptation (though his baby dragon form did). His character design inspired the Sacred Order of Holy Knights uniforms in the Guilty Gear franchise.
