Jimmy Sanchez

Private Jimmy Sanchez was a sniper that helped Sgt. Nathan Hale and Cpl. Dashiel find the only inhibitor which was crucial for the Sentinels survival.

Pvt. Sanchez first appears 30 miles west of Billings, Montana with the United States Army as they fight off the Chimera, the battle is going well when Sanchez is approached by an unknown officer who tells him to report to an installation in Keystone, South Dakota. Sanchez points out that Keystone is in Chimeran Territory to which the officer replies "not all of it".

Sanchez does go to Keystone and finds the base it is there that he meets Cpl. Dashiel, having heard that Sgt. Hale was a Sentinel he starts calling him a "Half blood creep" only for Hale to enter the room. Hale tells them that he specifically requested both Sanchez and Dashiel only for Sanchez to interrupt by saying that the mission was suicide after Hale tried to persuade Sanchez into doing the mission Sanchex then insults him for being half Chimeran to which Hale responds: "I didn't ask to become a Sentinel and you didn't ask to be here but like it or not we're infiltrating the conversion center near Salinas and extrating Dr. Silbermann before the Chimera find the new inhibitor."

Sanchez with no choice of declining joins them but still in the mission call Hale a "Stink" to which Cpl. Dashiel replies "Part Stink" Hale then says that the Chimera were there to which Sanchez seeing the place deserted disagrees only to have to run into cover and the Chimera ambush.

After defeating the Hybrids and Grey Jacks the three follow some Grims and Carriers to a conversion center, after entering the conversion center through a sewage pipe they find a room full of Spinner pods. Hale opens one to find Dr. Silbermann who tells him to get the inhibitor then kill him just as they are about to they are attacked by Spinners who manage to infect Sanchez and mortally wound Dashiel. Hale who manages to kill all of the spinners turns around to see Sanchez who comments about being able to feel the virus inside of him, Hale gets the inhibitor and plans to inject it into Sanchez to save him but upon realising this Sanchez tell him not to think of it he then comments about how good the Sentinels are and that the U.S. really needs them he then tells Hale to kill him before he turns Hale agrees by saying: "There's enough monsters in this world. I won't let you become one of them."
