Wildrun was the first Red Wolf from around 1760. He drove the Sioux from the planes while trying to secure a place for the Cheyenne to live. He claimed to be the human son of Owayodata, the Wolf God. He was picked by Kang to be a member of his Anachronauts, the greatest warriors of all time. Since Kang was the only person to ever defeat Wildrun, he pledged his loyalty to him.
He was the only Anachronaut to survive their battle with Immortus' forces.
