Wild Gunman is Duck Hunt's down special move in Super Smash Bros. for Nintendo 3DS / Wii U. The dog pulls out one of the five titular gunmen from Wild Gunman, which each have different properties, such as damage output and speed of firing. Attacking them momentarily stuns them, and if they take 5% damage or more (each gunman has 5 HP), they won't fire at all.
The gunman with the red scarf is the weakest gunman of the gang; the skinny gunman has better range with his shots; the gunman with the black suit can fire shots that send opponents flying at a horizontal trajectory; the gunman with the sombrero fires shots that have a fire effect, but he has the worst range of the five gunmen; the leader of the gang fires the quickest.
Each gunman appears at least once during a match, but when all five have appeared, the gunman that spawns when using this move the sixth time and beyond will be chosen randomly for the remainder of a match.
There are also two customizable variants of this special move:
Quick Draw Aces speeds up how quickly the gunmen can fire. Their shots deal slightly more damage, but have less range, and the shots deal less knockback as well. The gunmen also have only 1 HP, and will not fire at all if they're damaged by any kind of attack.
Mega Gunman summons a giant gunman who can withstand more damage than normal; the gunman's HP is increased to 40. However, the gunmen take longer to fire, and their shots deal slightly less damage than normal.
The five Wild Gunmen also appear in Duck Hunt's Final Smash, NES Zapper Posse.
