Karna

Serving as the Lancer-class hero in the Great Holy Grail War of Fate/Apocrypha, this powerful warrior was initially brought into the conflict by one of the Red Faction's puppet Masters. Although his origins lie with the Red Faction's forces, he eventually shifts his allegiance to become a key Servant under Shirou Kotomine. His presence on the battlefield remains a defining force throughout the intense struggle between the Red and Black factions.
