KL-E-0

KL-E-0 (or Kleo) is character and potential merchant appearing in Fallout 4.

Background
KL-E-0 is an assaultron with female AI that resides in Goodneighbor and acts as a merchant. She owns the store called Kill or be Killed which is located directly next to Daisy's Discounts. She sells a legendary missle launcher: Partystarter.

If KL-E-0's terminal is hacked, it's revealed that she has a contingency to kill several members of the Goodneighbor community, if the need arises.

Her plan to eliminate the Neighborhood Watch is to wait for a super mutant or raider attack, planting high explosives at key areas of the defensive perimeter, and - post detonation - relocating immediately due to Goodneighbor's vulnerability. Her contingency for Daisy is to shoot her with a laser from long range, as she is too close to Kill or be killed to outright assault her without raising suspicion. Her contingency to kill Bobbi No-Nose is to wait until night and sneak into the hideout they're working in, dismantling the lights and then killing one by one. Her plan to kill Whitechapel Charlie is to pay off one of his associates to do the dirty work for her.

Her contingency to kill John Hancock is to eliminate his bodyguard Fahrenheit first by strangling her in her sleep, and lacing all of the chems within the Old State House with poison. She understands that collateral damage may be possible but considers losses acceptable without too much disruption to her business.

KL-E-0 seems to hold a certain amount of respect for Magnolia, considering her a fellow working girl and willing to give her a chance before sudden termination. Her contingency consists of burning down The Third Rail as a warning, should she resist after that, a simple clean shot to the head would be the outcome. She has a holotape named Join The Railroad (a faction in The Commonwealth). Whether or not she actually supports The Railroad is unclear.

Other interactions
Robotic Expert perk allows hacking into her system and turn her into normal assaultrons. It will suspend her trading function temporally, and can return to normal trader after shutdown/activate while still following around in Goodneighbor like a third companion.
