Kimbleye Why is sirfetch'd pure fighting type you might as? Well it's simple. If you look at other pure fighting type pokemon they tend to be human-like manlets.
So it follows logically sirfetch'd is a human like manlet wearing a duck suit.
@SuperGideon Diogenes just straight up throwing a pokeball into the centre of the Gym where Plato is challenging upcoming pokemon master wannabes and a Sirfetch'd coming out of Diogenes' pokeball and him yelling "BEHOLD, PLATO'S MACHOP"
