Jayce, The Defender of Tomorrow

Armed with wit, charm, and his signature transforming hammer, Jayce lives to protect his native Piltover. He rose to prominence as an inventor, one whose magnetic personality and innovative creations brightened the lives of his nation's people. However, his technological marvels also attracted the attention of Piltover's enemies. Viktor, the machine-augmented scientist from Zaun, staged a deadly raid on Jayce's laboratory, barely impeded by the lab's meager security force. Viktor stole designs for an arcane power converter. Jayce feared that Viktor would create weapons of devastating power with the stolen technology. He implored the Piltover government to respond, but the officials were unwilling to support an act of aggression. Refusing to allow his own inventions to threaten the people of Piltover, Jayce decided to strike back against Viktor himself.
Jayce returned to his laboratory and began making preparations for his one-man attack. After an intense period of research, development, and hands-on testing, he emerged. He had created an array of powerful armaments, including his crowning achievement – the versatile, transforming Mercury Hammer. Armed and ready, Jayce began his assault, easily smashing aside Viktor's acolytes as they rushed to stop him. Jayce fought his way into the heart of the lab and confronted Viktor, forcing the Zaunite to flee. After destroying Viktor's prototype weapon, Jayce returned to Piltover where he was hailed as a hero. He reveled in the adoration, but he knew that his actions had provoked the nation's enemies. Now devoted to the defense of his people, Jayce is Piltover's best hope for a bright future.
