Duck Hunt (ダックハント, Duckhunt), known in PAL regions as Duck Hunt Duo, is the name of a playable trio composed of the dog, a duck, and the off-screen hunter from the NES light gun game, Duck Hunt.
Throughout Duck Hunt, the goal is to shoot all of the ducks with a limited amount of bullets and time. By plugging a controller into the player 2 slot in the NES, a duck can be controlled to a limited extent by another player.
The hunter is the playable character in all versions of Duck Hunt and is supposed to represent the player. Accompanying the player is a non-playable scent hound, who flushes out the ducks for the hunter to shoot and picks up any ducks that are shot down by the player. If the player fails to shoot down any ducks, the dog infamously laughs at the player's misfortune before slinking back down into the grass. While the home console version does not allow players to shoot the dog, the arcade version, Vs. Duck Hunt, allows players to shoot the dog in the bonus rounds. However, successfully shooting the dog immediately ends the bonus round and yields no points.
In Super Smash Bros. MeleeSuper Smash Bros. Melee marks the debut of the Duck Hunt universe within the Super Smash Bros. series. The Duck Hunt universe is represented by a collectible trophy that consists of two ducks, and its description references both the hunter and the dog from Duck Hunt.
A concept similar to Assist Trophies was considered for Melee, with one example being the ducks from Duck Hunt flying around the stage and interfering with characters. However, the idea was scrapped due to developmental circumstances.
In Super Smash Bros. Brawl
Super Smash Bros. Brawl marks the second appearance of the Duck Hunt universe. Instead of a trophy, the Duck Hunt universe is represented with a sticker of a duck. Fittingly, the sticker can only be applied to the Ice Climbers, Mr. Game & Watch, Pit and R.O.B., all of whom are retro characters like the ducks and dog.
In Super Smash Bros. 4
Main article: Duck Hunt (SSB4)
Super Smash Bros. 4 marks the third appearance of the Duck Hunt universe, and most notably marks the debut of unlockable representatives for the Duck Hunt universe. Masahiro Sakurai stated that the inclusion of playable Duck Hunt representatives was influenced by that respective game's worldwide sales numbers, and his feeling that the Duck Hunt universe had not been viable for such representation until SSB4.
Much like the Ice Climber universe having been represented by its titular characters functioning as a playable tag team, the Duck Hunt universe's playable representatives also function as a team, albeit as a trio: the hunting dog and a duck fight together as a duo, while an off-screen hunter aids them by firing shots with the NES Zapper. Two of their special moves also reference other light gun games contemporary to Duck Hunt: their neutral special involves a metal can from the "Trick Shot" minigame from Hogan's Alley, while their down special involves the gunmen from the NES game Wild Gunman. Duck Hunt were the final newcomers to be officially revealed.
Duck Hunt are currently ranked 42nd out of 58 on the tier list, placing them in the F tier. Their multiple projectile specials make them capable at stage control and zoning, with Trick Shot being the most useful due to its remote controllable property. They also have a good air game, as their sweetspotted neutral aerial, up aerial and sweetspotted back aerial are capable KOing options, while their forward aerial is useful for edge-guarding. However, their KO potential is very inconsistent, due to having a very minimal number KOing options and their smash attacks' very awkward hitbox placements making them liable to fail at landing all of their hits. Their recovery move, Duck Jump, grants decent vertical distance, but minimal horizontal distance and is both slow and unprotected, which leaves them wide open to edge-guarding and forces them to use the dog's ability to wall jump more often than not. Their reliance on projectiles is also highly ineffective against characters who possess reflectors and especially Rosalina & Luma, who can completely nullify their projectiles with Gravitational Pull.
As a whole, Duck Hunt's weaknesses are fairly detrimental, and their unfavorable matchups against characters who can reflect or otherwise negate their projectiles have resulted in their tournament representation being unremarkable. Despite this, they have managed to achieve decent results at the regional level and even better results than several characters ranked higher than they are.
