Fantastic

 is a man living in the Mojave Desert in 2281 and is working as a technician for NCR, hoverer it is obvious that his technical expertise is severely lacking.

Background
Fantastic was recruited by NCR, after they required technical experts for working at HELIOS one power plant. He claimed that he have both knowledge of solar power plants and "theoretical degree" in physics to get the job.

Interactions with the player character
You can either help him get the laser running for the NCR, or kill him and use it for yourself. If you get Helios running and send the energy where he asks you to he can later be found at the dam. Killing him may not result in hostile actions from people who witness it. If the player has the Wild Wasteland perk, when the player approaches Fantastic a small quacking sound will begin to emit, indicating the obvious fact that he is a "quack".

If the player chooses to kill the NCR in That Lucky Old Sun and leave Fantastic alive, when he/she returns Fantastic is wearing Legion armour and has killed the other scientist. If you talk to him he will say "Hey man, when in Rome".

If the player chooses to side with the NCR, Fantastic can be found at Hoover Dam. He gets a promotion to the position of "God Damn Dam God" in his own words.

appears in Fallout: New Vegas.
