After being fired, Kane traveled the U.S., having many different jobs, including a job as a special agent and bodyguard for Theodore Roosevelt. Kane was also involved in the invasion of Cuba. After that Kane is set to hunt for The Wild Bunch and ends up collaborating with Butch Cassidy and Sundance Kid instead of arresting them. Kane's health began to decline, and in 1910 he supported and fought with Pancho Villa during the Mexican Civil War. It was here that he met his unknown son, "Diablito", Paco Galàn. Together they traveled to Europe where Diablito became a famous matador. Later, Kane traveled back to America where he was again reinstated as a U.S. Marshal.
