CM Punk started out as a self taught background wrestler before transitioning into a star on the independent scenes in the early 2000’s. He would sign with WWE in 2005 and would go onto become a world champion, most notably beating John Cena to win the title at Money in the Bank 2011. An outspoken attitude and clashes with management would lead to Punk become disillusioned however, and he left WWE in 2014. Though he briefly fought in the UFC, he returned to pro wrestling after debuting with All Elite Wrestling in August 2021.
