If you look closely at what Wahl says while he is about to fire his magical cannon (can't remember the exact page as of this moment), you will notice that he says something along the lines of: "I am the greatest Machias of all, master Wahl!" So yeah; kinda proves that he is a machine as well.

Hope that helped you. ^_^
