Duck Hunt (character)

Duck Hunt (known as Duck Hunt Duo in the PAL localization, and individually referred to as Dog and Duck) is the name that refers to both the playable dog and duck fighters in Super Smash Bros. for Nintendo 3DS / Wii U. They are two major characters from the NES video game they are named after, Duck Hunt. Besides premiering as playable characters in Super Smash Bros. for Nintendo 3DS / Wii U, the duo has also made other crossover guest appearances with the Mario franchise in other instances, mainly in the WarioWare series.

Super Mario Bros.
Though not appearing in the game itself, Super Mario Bros. was re-released multiple times, bundled with other games within the same cartridge. Two releases included a copy of Duck Hunt: 2-in-1 Super Mario Bros./Duck Hunt and 3-in-1 Super Mario Bros./Duck Hunt/World Class Track Meet.

WarioWare, Inc.: Mega Microgame$!
In WarioWare, Inc.: Mega Microgame$!, a microgame called Duck Hunt appears, and has overall the same gameplay as the original NES game, this time having the player uses the Game Boy Advance controller to shoot ducks.

WarioWare: Twisted!
A Duck Hunt microgame similar to the one from WarioWare, Inc.: Mega Microgame$! appears in WarioWare: Twisted!, this time using the Game Boy Advance cartridge's tilt sensor to aim.

WarioWare: Touched!
While the dog does not appear in WarioWare: Touched! at all, the original sprites of the ducks are occasionally released from the ball in the microgame Clawing for More after clearing it.

WarioWare: D.I.Y. Showcase
The Duck Hunt microgame returns in the WiiWare game WarioWare: D.I.Y. Showcase, and utilizes the Wii Remote's motion controls.

Tetris DS
Gameplay of Duck Hunt can be seen on the Nintendo DS's top screen in stage 19 of Standard Marathon mode in Tetris DS, where the dog and duck make a cameo. The dog also appears as a sprite on the touch screen during this stage.

Super Smash Bros. for Nintendo 3DS / Wii U
Duck Hunt appears as unlockable playable characters in Super Smash Bros. for Nintendo 3DS / Wii U. Unlike other duo fighters, the dog and duck are a singular fighter. Their moveset generally consists of moves based around the NES Zapper and its games, such as their smash attacks, which involve a Zapper being fired three times.

Duck Hunt's neutral special move is Trick Shot, in which the dog kicks a can from Hogan's Alley. Their side special move is Clay Shooting, in which the dog throws out a clay pigeon from Duck Hunt. Their up special is Duck Jump, in which the duck flies up while carrying the dog, and their down special is Wild Gunman, which spawns one of the five titular gunmen to attack. Their Final Smash is a shootout of characters from some NES games that have used the Zapper: Wild Gunman, Hogan's Alley, and Duck Hunt.

In terms of customizations, Duck Hunt is the only fighter who can use the Collar and Feather equipment to increase defense and speed, respectively. The duo can also use the Zapper equipment for attack, which references their game origins.

A Duck Hunt-themed stage simply called Duck Hunt also appears in both games. In the stage, the sprite versions of the dog and the ducks appear.

Palutena's Guidance

 * Pit: I don't want to fight that cute dog!
 * Palutena: Oh, you won't. You'll be fighting the dog AND the duck.
 * Pit: So...if I win...
 * Pit: is duck on the menu for dinner?!
 * Palutena: Let's take things one step at a time, Pit. These two may seem like a duo, but they're actually a trio! Together, they're known as "Duck Hunt."
 * Pit: So where's the third team member?
 * Palutena: Listen, just be careful. You could get shot out of nowhere.
 * Pit: A mysterious sharpshooter, eh? Well, that does make things more exciting!

Trivia

 * The Duck Hunt microgame in WarioWare: Touched! bears the Duck Hunt title, but instead of featuring the iconic dog and ducks, it uses clay pigeons from Game C in Duck Hunt.
 * Duck Hunt is the only playable character in Super Smash Bros. for Nintendo 3DS / Wii U to break the fourth wall in their trailer.
