"It's called a 'Mouse Hole'. Cuts through anything, really. I designed it a year ago and submitted it for testing, but it never reached distribution."
"Top agents always hog the good stuff."
Leo Fitz and John Garrett[src]

The Mouse Hole is a laser-cutting device capable of cutting through almost any material. It was created by S.H.I.E.L.D. agent Leo Fitz, and though it was not mass-produced, it has been developed for high-ranking agents.



Created by Leo Fitz, the Mouse Hole never went to production for field agents.[1]

HYDRA Uprising

Mouse Hole WS

S.H.I.E.L.D. Director Nick Fury used a Mouse Hole to escape from his destroyed vehicle during an assassination attempt by the Winter Soldier.

Maria Hill later used a Mouse Hole to free Captain America, Black Widow and Falcon from a HYDRA assassination squad.[2]


Around that same time, Fitz used a Mouse Hole to affect the escape of his team from the Bus when Victoria Hand sent a kill-squad aboard the plane, falsely believing that Coulson and his team were HYDRA sleeper agents.[1]

Chase of Carl Creel

Lance Hunter got stuck in a S.H.I.E.L.D. SUV after it was flipped by Carl Creel. Melinda May planned to use the Mouse Hole to get Hunter out of the car, but he told her to continue the chase for Creel. Before leaving, May gave Hunter the Mouse Hole which he used to escape from the SUV. After escaping he was caught by soldiers from the United States Armed Forces.[3]

Search for the Kree City

The city that matched the Words of Creation was found underground. Alphonso Mackenzie used the Mouse Hole as a cutting tool to make an opening to a 100 foot shaft leading down to its entrance.[4]
