Night-Night Gun

"Whoa, whoa, whoa! Watch it, that's the Night-Night Gun!" "Well, it's on my stuff, it doesn't work and there's no way we're calling it the "Night-Night Gun."

- Leo Fitz and Jemma Simmons

The Night-Night Guns are a prototype tranquilizer rifle and pistol set designed by S.H.I.E.L.D. scientists Jemma Simmons and Leo Fitz.

Use
"The bullets work. Non-lethal, heavy stopping power, break up under the sub-cutaneous tissue--" "Oh, with a dose of .1 microliters of dendrotoxin. I'm not Hermione. I can't create instant paralysis with that."

- Leo Fitz and Jemma Simmons

Basically a miracle born of engineering and bio-chemistry, these custom tranquilizer weapons—or as Agent Fitz likes to call them “The Night-Night Gun"—is the perfect tool for stopping someone without killing them.

The rifle fires non-lethal bullets with heavy stopping power that break up under the subcutaneous tissue (or skin). From there, the bullets deliver a tiny amount of dendrotoxin, incapacitating the target long enough for them to be secured and without any harmful side effects in the process.

The Night-Night Pistol utilizes eight .45 caliber cartridges in a semi-automatic firing mode with a therapeutic dose of the dendrotoxin.

Rifle History
Agent Grant Ward used the rifle to tranquilize the unstable Michael Peterson.

Pistol History
"We're gonna have this new 'Night-Night' pistol working in no time, okay?" "Great. One thing. We're not calling it that." "Told you." "Yes, we-- Yes, we are"

- Leo Fitz, Grant Ward and Jemma Simmons

Phil Coulson used the pistol variant to knock out Akela Amador in her hotel room.

Coulson later attempted to use it to non lethally take down Chan Ho Yin, but all of the rounds were destroyed by his flames, necessitating a more lethal course of action.

Simmons used the Night-Night pistol to incapacitate Agent Jasper Sitwell at The Hub.

Melinda May used the Night-Night pistol to sedate Hannah Hutchins during an "Index Asset Evaluation and Intake" report in Utah that had grown tense.
