Competitors such as McDonald's and Wendy's have attempted to create burgers similar to the Whopper, often nicknamed a Whopper Stopper during the development phase.[19] Wendy's created the Big Classic with similar toppings but served on a bulkie roll, while McDonald's has created at least six different versions, including the McDLT,[20] the Arch Deluxe,[21] and the Big N' Tasty.[22][23]
