Ambassador Dennis Crocker

 is the ambassador of the Mojave Wasteland for the New California Republic in 2281.

Background
Crocker is the NCR ambassador to the Mojave area. He was given this position because he supported president Kimball during the election. 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 treaty of New Vegas.

Interactions with the player character
When the courier arrived at the New Vegas Strip for the first time, you will receive a letter from Crocker delivered by an NCR soldier. In the letter he requested that you come speak to him at the NCR Embassy. If you go and see him, he will ask that you help the NCR in taking control of the region. He will first ask you to act as the representative of the NCR and get the support of the Boomers in the quest Things That Go Boom. After you finish the quest Volare! and have become idolized by the Boomers, you can speak to Pearl and ask her for support during the Battle of Hoover Dam. Once it is done, you can return to Crocker and tell him that the Boomers are now on NCR's side.

Afterwards he will give you the quest King's Gambit and ask you to stop the attacks against NCR civilian settlers on Freeside. If you haven't used your favor from G.I. Blues yet, you can use it to ask The King to stop the violence and finish the quest easily in a diplomatic manner. If that isn't an option, you will have to return to Crocker and tell him that the Kings are unwilling to stop the violence. He will then give you authorization to get support from the NCR military by either asking Colonel Moore at Hoover Dam or Colonel Hsu at Camp McCarran. If a violence solution was taken, you will have to apologize to Crocker in order to get your award. But in either case, the attacks on NCR civilians will stop.

Once both quests are completed, Crocker will tell you that he no long have any task for the courier and ask you to Colonel Moore at Hoover Dam for more missions.

In the quest King's Gambit, after learning from Rotface that Pacer has a Jet addiction, return to the embassy. After telling Crocker this information, you'll have a special dialog option for Wild Wasteland, which causes Crocker to shout "DAMN IT, I'M AN AMBASSADOR, NOT A DOCTOR!" This is likely a reference to Star Trek.

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. This has been a bug in the game and you can no longer complete quests with the NCR because Crocker disappears permanently.(Bug is confirmed in the Xbox 360 and PS3.)

It is however possible to spawn the Ambassador if he disappears permanently using the following command:

''player.placeatme 112640 ''

Sometimes if you punch him then hold square he will get up from his chair, start spinning and then get in the floor. If you talk to him he will come back but when you say goodbye he will get in the floor again (Experienced on PS3 version).
 * When the player has idolized status with the NCR, Crocker greets the player with "It's good to see such an outstanding citizen of the NCR. What can i do for you, my friend?" The subtitles however read: "It's good to see such an outstanding hero of the NCR."
