Wii U Pro Controller
The Wii U Pro Controller features two analog sticks, a D-pad, A, B, X and Y buttons, the L and R shoulder buttons, and two Z buttons (labeled ZL and ZR) next to the L and R buttons, respectively. Alongside the shoulder buttons are clickable analog sticks. In the center are + (Start), - (Select), Home, and Power buttons. This controller is one of several compatible with Super Smash Bros. for Wii U.
The Wii U Pro Controller has only been made officially compatible with the Wii U, as it was not made forwards compatible with the next-generation Nintendo Switch console. However, it's optional wired connection allows the controller to be plugged in to other devices like a PC, making it unofficially compatible with games on those systems.
Standard Controls (Super Smash Bros. for Wii U)
The Wii U Pro Controller has the highest latency out of all usable Smash 4 controllers barring the Nintendo 3DS, experiencing lows of 75.36ms (4.5 frames) and 93.7ms (5.5 frames). This makes it up to a frame slower than a Wii Remote or GameCube controller in some situations.
In competitive play
Excluding the GameCube controller, the Wii U Pro Controller was the most popular controller in Super Smash Bros. for Wii U. It effectively replaced the Classic Controller due to being more easily accessible for new players at the time, though some did not convert due to swearing by its lower latency. Its flexibility of being wired or wireless without the need for an adapter and being shaped more like an industry standard controller also made it enticing, though some complaints like the stick placement were prevalent.
