Ok, this is stupid to even mention. The handgun looks nothing like the Mark 23. It doesn't even have ANY basic resemblance to the gun. I see nothing that reminds me of the Mark 23.

Samus's gun also looks nothing like the taser not even a passing resemblance Excalibur01 10:41, 2 September 2012 (CDT)

Fictional Weapons

Handgun

Blaster pistols are used by Fox McCloud ,Falco Lombardi, and Wolf O'Donnell's heavily modified version; Fox and Falco's versions are fitted with underbarrel non useable laser sights, Wolf's heavily modified version has a underbarrel mounted bayonet(!).

Fox and Falco side by side with their modded H&K Mark 23s.

"Can't let you do that Starfox" Fox and Wolf get into a classic Mexican Standoff with their two Mark 23s.

Nintendo Super Scope

Yeah you read that right the Nintendo Super Scope from your childhood is in the game as a laser rifle. The Scope Primid enemy in adventure mode uses a modified version of it.

Cracker Launcher

The Cracker Launcher is a rocket launcher that fires fireworks up to 20 times. While fictional itself it appears to be modeled after a M136 AT4 but with some features missing such as all the markings are replaced with a simple up arrow and missing its sights and changes include its massive decrease in size, enlarged barrel and exhaust port, and a wider body in general.

Only in a Nintendo game can a child hold and fire a rocket launcher.

Zero Suit Samus's Taser

While in her Zero suit Samus uses a weapon that is a combo of a taser, a whip, and a blaster.

Peanut Popgun

Diddy Kong uses the Peanut Popgun from DK64. The Peanut Popgun is true to its name as it fires Peanuts instead of actual ammunition. You can even eat the the fired peanuts which Octacon and Snake have a humorous conversation about:

Snake: "Otacon, there's a chimpanzee here wearing a Nintendo hat."

Otacon: "That's Diddy Kong. He's Donkey Kong's partner. Not only is he lightweight, he can use a wide range of weapons as well. He can fly using those barrel jets on his back, and he can shoot nuts with his Peanut Popgun."

Snake: "Peanuts? As in the ones in the little shells? Are you serious?"

Otacon: "Wait, here's the best part. You see them lying on the ground after he shoots? If you pick up some of those peanuts, they'll restore your health a little."

Snake: "Hmm. Edible ammunition, huh... Times sure have changed."
