Ambassador Dennis Crocker

Dennis Crocker is the ambassador to New Vegas for the New California Republic in 2281. His full grandiose title, according to the note written to the Courier, is "Ambassador Extraordinary and Plenipotentiary."

Background
Ambassador Crocker began his political career as a mayor in NCR sometime before 2261, and worked his way up through the ranks. He was the head of Kimball's campaign for his successful run for NCR council, which he attributes to why he has his current position. Crocker is a strong believer in diplomacy and hopes to unite the Mojave Wasteland under the NCR peacefully. However, his work has made very little progress since Mr. House refused to even meet him in person after signing the New Vegas Treaty.

Ambassador Crocker is the third successor of the title of ambassador to the Strip following Susanna Edith, and is in his seventh year of Ambassadorship in 2281. He keeps himself busy with the day-to-day paperwork and aiding the NCR police in keeping troops in line on the strip. Though he hopes for the annexation of New Vegas, he has little hope for success and believes his predecessors expected too much of Mr. House in this area. Crocker believes once the Legion is no longer a threat to the Mojave, negotiations may be able to proceed at a better pace.

Quests

 * Things That Go Boom: Crocker wants you to start diplomatic ties with the Boomers. After finishing the quest Volare! and becoming idolized by the Boomers, they can speak to Pearl and ask her for support during the Battle of Hoover Dam. Once it is done, they can return to Crocker and tell him that the Boomers are now on NCR's side.
 * Kings' Gambit: Crocker will ask the Courier to stop the attacks against NCR civilian settlers in Freeside.

Other interactions
When leaving the Lucky 38 after speaking with Mr. House, the Courier will receive a letter from Crocker delivered by an NCR trooper. In the letter, he requests that they come to speak with him at the NCR Embassy, agreeing to pardon them of any crimes they may have committed against the NCR up to that point.

Appearances
Dennis Crocker appears only in Fallout: New Vegas, and is mentioned in Lonesome Road if the player character has high reputation with the NCR.

Behind the scenes

 * Dennis Crocker was originally intended to be a Caucasian male, however, due to an error, a non-Caucasian voice actor recorded his lines. The character's appearance was altered accordingly.
 * The golden yellow flower on the left pocket is a California poppy, the state flower of California.

Bugs

 * If the Courier waits in the Embassy at night when Ambassador Crocker isn't around, waiting for him to appear in the morning/afternoon, he will not appear in the building. All you have to do is take your player and exit the Embassy and re-enter for the Ambassador and his secretary to appear in the Embassy. He will not always reappear though, sometimes disappearing from the game permanently.
 * On the PC, this can be corrected by opening the console and entering, followed by.
 * Alternately, open the console and enter
 * Upon completing "Things That Go Boom" if you become idolized by the NCR a random MP will act as the male assassin for one who does wrong towards the NCR. He will complete his line and then attack you. Killing him does not cause infamy.
 * When the Courier would like to know more about the NCR when having a negative reputation(merciful thug), the spoken text is not the same as the text on the screen.
 * In the subtitles it says the hero of the NCR while he says citizen of the NCR.
 * While receiving the quest Kings' Gambit if the Courier asks about the other option besides assassinating Pacer, Ambassador Crocker will suggest the Courier "integrate" with the King, when the subtitles say "ingratiate."
