Timmy and Francis is the relationship between Timmy Turner and Francis Callahan.
Francis hates Timmy as much as Chester and A.J., and mostly bullies him. He was also beaten up by Timmy on several occasions. One day, Timmy, Ivan and their fairies travel back in time to see how and why Francis is who he is today. In a way, the two feel sorry for Francis on how rough his early childhood was and has been requested to do one interpretive dance with him, yet they still remain enemies.
