Illfang the Kobold Lord was the boss of the 1st Floor of Aincrad in Sword Art Online. He is a giant humanoid kangaroo with fiery red skin, sharp yellow teeth, glowing paradise pink eyes, long ears, a arrow blue stripe in the middle of its body and wears a lucador mask on its head with two spikes.
Background[]
It took a mouth to find the boss, as the players were having a hard time finding the boss room. Beta testers, including Kirito, also had difficulty finding the boss room. Illfang the Kobold Lord was slain by Kirito, who gave the final blow to the boss, and received the last-attack bonus item, Coat of Midnight.
