Melissa (Fallout: New Vegas)

 is a Great Khan living in the Mojave Wasteland in the year 2281.

Background
Melissa is a member of the Great Khans. Her and two other Khans are awaiting a Chems shipment at the Great Khan Encampment above Quarry Junction.

Melissa has a New Zealand accent, so it is possible that her deceased mother (who is mentioned by Chomps Lewis) has a New Zealand background, as Chomps mentions that Melissa has a lot of her mother in her.

 * There is no way of completing the "Oh my Papa" quest if you speak to Melissa first and do the "Don't Make a Beggar of Me" quest. It does not matter if you turn her in, or if you give her the chems, the very act of completing the quest makes her dissapear. The "Oh my Papa" quest the marker will still point at the Great Khan Encampment but she will not be there.
 * If you are playing on the PC you can use console commands to fix this glitch (type: PlaceAtReticle 00e595c in the console to spawn Melissa at Great Khan Encampment) but if you playing on the 360 you are screwed out of completing yet another quest. Happens on PS3 as well.
 * Another way to make her appear again is to use the commands:::
