Tomas

 is a traveler wandering the Mojave Wasteland in 2281.

Background
Tomas approaches the Courier after getting into a Gunfight with Jacklyn who had been his traveling companion. It is implied that Jacklyn attacks him for his "Lucky Necklace" which turns out to be made of 7 Sunset Sarsaparilla Star Bottle Caps. Alternatively, Jacklyn may actually win the Gunfight and run over to you, saying how Tomas tried to kill her. She will have all nine Sunset Sarsaparilla Star Bottle Caps on her (the 2 she had initially and the seven from Tomas's Necklace).

Other Interactions
If Tomas survives the Gunfight between him and Jacklyn, he will rush over to the Courier. He will tell the Courier about his lucky necklace containing the Sunset Sarsaparilla bottle caps, and the Courier can obtain the bottle caps in a variety of ways:
 * If you have Terrifying Presence Perk you can get the necklace for free and not lose Karma.


 * A speech challenge may be passed in which he is convinced the bottles are bad luck, and gives them to the courier. Tomas may also be killed or pickpocketed for them, and looted for a low grade weapon and armor, as well as "Tomas's Journal".


 * Failing the speech challenge and demanding the necklace will result in Tomas turning hostile, giving the player free rein to take him down.


 * Just a curiosity: If you follow him (after winning that fight with Jacklyn), Tomas strangely disappear right in the center of Mojave Outpost. (Confirmed on Xbox 360)

Appearances
appears in Fallout: New Vegas.

Tomas's Journal
The last entry of the journal reads:

Things finally seem to be turning around. I made a nice bundle of caps turning in some scrap at the last town I passed, and now I have a new traveling companion. Her name is Jacklyn, and she's pretty cute. I'm not going to get ahead of myself here, but things are looking up! And to think I was actually beginning to doubt the power of my lucky necklace!
