Phineas and Ferb: Legends with The Dark Knight by AceOfKnaves reviews
Two worlds meet for the first time. Three freinds are separated, on three different sides of the battle lines, in Gotham City. Phineas' sanity hangs in the balance. Isabella is finally brave enough to make a move on him, with the help of a new friend. And Ferb finds someone who talks almost as little as he does? Romance later on. Rated T for for possible disturbing elements.
