Teenage Luigi is Luigi as a teenager, appearing in an upcoming Mario & Luigi title. It is known that he, along with Baby Luigi and Young Luigi, will interact with the current, older Luigi. Teenage Luigi, along with his brother, is a freshman at the Brooklyn Plumbers Academy (a reference to The Super Mario Bros. Super Show! episode "Plumbers Academy"). He would later appear in the R.O.B film, as one of the several alternate universe characters that appear in the film.
