Foreman Krag (クラグ族長 Kuragu zokuchō?, lit. "Patriarch Krag") is the foreman and leader of the Kron race, introduced in Sonic Chronicles: The Dark Brotherhood. He is mostly tasked with keeping the miners and factory workers happy.
Thousands of years ago on his homeworld, Planet Kron, Krag ruled over his people with an iron fist, but was one day trapped inside the Twilight Cage, along with with his people and their civilization. Some time after arriving there, Krag and his people were invaded by the Nocturnus Clan, but Krag refused to give into their leader Imperator Ix's demands. The Kron were eventually conquered by the Nocturnus Clan and Krag was forced into a life of servitude for the Nocturnus Clan. The "gritty taste" of the life as a slave caused a change in Krag, and he became a fair leader over his people.
Krag also set up the meeting with the N'rrgal, Zoah and Voxai to invade Nocturne. He commented that they were in war with Ix, and that Sonic liberating the Kron factory would accelerate this war. At one point, you can have Sonic comment that they didn't want a war, to which Krag answers that there already was one.
