Later, the Hulk and Spider-Man turned up in Liberty, and Col. Tremens and the army tried to kill both them and Woodgod. Woodgod escaped and returned to the Pace farm, using David Pace's notes to teach himself how to read. Using Pace's notebooks and equipment, Woodgod began genetic experiments using the methods he had discovered and created the sentient half-humanoid half-animals of human intelligence that he called the Changelings. He resisted a coup by the murderous Changeling Leoninus. He soon left the Pace farm and found a valley in the Colorado Rocky Mountains where he established a community for the Changelings, and became the Lawgiver of the Changelings.
