Git is a large, muscular gray lab rat in the film Ratatouille.
Ratatouille
Git was presumably subject to science experiments that gave him increased strength, his sheer size eclipsing all other rats.
He is first seen helping Remy board a makeshift boat Django was in to escape from the old lady, but is unsuccessful, as Mabel fires on the spatula he is holding and causes him to lose his grip on it. Later on, when Remy is reunited with the rest of the clan, Emile told Git and his friends about Gusteau's. Remy is reluctant, but concedes when Git intervenes and does so, only to see more and more rats coming to Remy to ask for food.
When Remy gets into an argument with Linguini for denying him credit, Git notices this and jokingly states that Linguini is like a "fluffy buddy" of Remy, and joins the remaining rats to steal from the restaurant, only for them to all be evicted by Linguini, eventually leading to Skinner capturing Remy, who pushes Emile out of the way. Emile contacts Django, who brings Git to dislodge Gargoyles and smash open Skinner's car trunk, allowing Django and Emile to rescue Remy. Git would later be assigned to tenderize meat. After capturing the Health Inspector, the rats tie him up and throw him into the freezer, with Git closing the door shut.
After the closure of Gusteau's, Git now hangs out at La Ratatouille, showing baby rats his muscles.
