Duck Hunt

Duck Hunt (known as Duck Hunt Duo in European languages, and individually referred to as Dog and Duck) is the name that refers to the playable tag team of a hunting dog and a duck in Super Smash Bros. for Nintendo 3DS / Wii U and Super Smash Bros. Ultimate. True to their team name, the dog and duck are from the Nintendo Entertainment System video game Duck Hunt. In addition to their appearances in the Super Smash Bros. series, the dog and variants of the duck have made other crossover guest appearances within the Mario franchise in other instances, mainly within the WarioWare series.

Super Smash Bros. for Nintendo 3DS / Wii U
Duck Hunt appear as unlockable newcomers in Super Smash Bros. for Nintendo 3DS and Super Smash Bros. for Wii U. Although they fight as a duo, Duck Hunt do not truly adhere to the tag team archetype first used by the Ice Climbers and perpetuated by Rosalina & Luma. This is due to the duck's own hurtbox being directly next to the dog's hurtbox at almost all times. Duck Hunt's moveset largely consists of moves based around the NES Zapper and games that use it, particularly Hogan's Alley and Wild Gunman, while incorporating physical attacks from both the dog and duck.

For their stage entrance, the dog leaps into an 8-bit sprite of grass with the duck on his back before they both rise from the grass while the dog performs his signature laugh. Duck Hunt's standard special move is Trick Shot, in which the dog kicks a tin can from Hogan's Alley forward that can be subsequently fired at with the Zapper. Their side special move is Clay Shooting, in which the dog throws out a clay pigeon from Duck Hunt's Game C that will then explode upon being fired at by the Zapper. Their up special is Duck Jump, in which the duck flies upward while carrying the dog. Their down special is Wild Gunman, which spawns one of the five titular gunmen to attack. Lastly, their Final Smash is NES Zapper Posse, which consists of a flock of ducks from Duck Hunt ramming the opponent into a field before the gunmen from Wild Gunmen fire at them and the cutouts from Hogan's Alley.

In regard to character customization, Duck Hunt are the only fighters who can use the Collar and Feather equipment to boost their defense and speed, respectively. The duo can also use the Zapper equipment to boost their attack strength, which is another reference to their home game. 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, even if Duck Hunt themselves are fighting on the stage. In addition, Duck Hunt are the only playable characters in Super Smash Bros. for Nintendo 3DS / Wii U to break the fourth wall in their trailer.

Super Smash Bros. Ultimate
Duck Hunt return as unlockable veterans in Super Smash Bros. Ultimate. For their transition, Duck Hunt received noticeable improvements to their moveset and the dog can run faster, although they are now noticeably lighter. The dog is also much more vocal, as he barks and yelps in a number of instances instead of solely during their star KO animation. Along with several other characters, Duck Hunt retain their victory theme from the previous game, albeit sped up.

Duck Hunt reappear in Banjo & Kazooie's announcement trailer "Best Friends", with a similar role to King Dedede in the King K. Rool announcement trailer, "The Rivals".

 * These two were the stars of the NES launch title Duck Hunt, way back in 1985. This goofy dog would chase down any ducks hit by the Zapper accessory, but wasn’t shy about laughing at missed shots. In Super Smash Bros. for Wii U and Nintendo 3DS, these two work as a team to fight. Quack! Bark? Both!
