Plate

Plates are items found in various Mega Man games.


 * In Mega Man 5, there are 8 plates: M, E, G, A, M, A, N, and 5. Each one is in a different Robot Master stage.  When you get all of them, you unlock Beat, who can assist you in Wily's fortress; notably, against all 4 Dark Men.


 * In Mega Man 6, there's four plates to collect: B, E, A and T. You gain those plates after defeating Tomahawk Man, Yamato Man, Knight Man and Centaur Man passing through the correct doors.


 * In Mega Man 7, there are still four plates that you collect: R, U, S, and H. Like Mega Man 5, each one is in a different Robot Master stage.  When you collect all of them, you unlock Rush's Super Adapter function.


 * In Mega Man IV, there are 8 plates: B, E, A, and T are in the first four stages, and collecting them allows you to use Beat as before. W, I, L, and Y are in the second four stages, and they are required to access Dr. Wily's fortress.
