Rachel Foley

Why is this happening, why me?

Rachael was an agent of the of the United States Federal Government's anti-bioterrorism taskforce F.B.C. (Federal Bioterrorist Commission); she and her partner Raymond Vester were sent into the Queen Zenobia to investigate.

Queen Zenobia
In 2005, Rachael with her partner Raymond Vester was sent to the Queen Zenobia to investigate. Nothing much was known what Rachael was doing while Raymond was following the steps of Jill, Chris, Keith and Quint. While Rachael was new to the FBC, she never knew what horrible things would eventually happen to her.

Rachael was maybe sent to get the T-Abyss or she was sent to get the vaccine so that Morgan would be able to hide the virus.

Transformation
Found you...

Transformed into an Ooze, she attacked B.S.A.A. agent Jill Valentine. She fled after taking heavy damage and Jill was forced to hunt her down in order to retrieve a key Rachael had acquired before mutating. Eventually Jill and fellow agent Parker Luciani seemingly killed her for good.

However, Rachael somehow survived the encounter and frequently attacked the duo as they explored the ship (which greatly annoyed Parker). She was invincible to gunfire but could be stunned long enough for them to escape.

The mutated Rachael was presumably destroyed permanently when the Queen Zenobia exploded.

When fighting Rachael, it is a good idea to bring along a Magnum or Rifle (with charging capabilities if the player has one.) as they do the most damage to her. However, a shotgun is also recommended. When "killed" on subsequent encounters, she drops Illegal Custom Parts for weapons that can be retrieved by the player by walking over her body and pressing Y or ZR.

Trivia

 * An interesting addition to Rachael is her long blonde hair being constantly over her eyes.
 * Her mutation is unique as when she fully transforms, her right arm appears to be severely deformed and a huge hole opens up on the top of her head. A long, thick tongue-like protrusion comes out of her head. Her hair cover most of her body. With time, it is possible she may have become a Sea Creeper. However, she cannot go through doors and when fighting her, she blurts out phrases like "It hurts" and "killed".
 * It is unknown how long Rachel survived her 'last moments' as when Jill found her, she was speculated as dead. However, as you progress through the game, you find out Rachael wrote down her final moments, thus surviving after Jill left:I was forced on this mission. I had no desire to come here for a job that could get me killed. At any rate, stage one is complete. I got the key for the freight lift. Now I can access the bilge. This ship was used as the base of operations for the terrorist attack on Terragrigia one year ago. I found the UAV in the ship's foredeck that was used to disperse the virus. Finding the UAV was good; getting attacked out of nowhere by an ugly monster was bad. I knew this mission would suck from the moment I took it. My head feels like it's going to split open. I lost an eye already. It's hard to see. I feel like crap. Arms are starting to feel weird too. My right arm split into two. Blood all over my body, can see my bones. need doctor bad.
 * Rachael is the only unique character to be unplayable in Raid Mode.
 * While the official Japanese website spells her name as "Rachel", other publications use "Rachael".
 * Rachael does not appear in the Mercenaries 3D demo version, she is instead replaced by a generic male named Richard.
 * She is slighty similar to both Nemesis and Mr. X due to the fact she appeared a numerous amount of times after Jill seemingly kills her; upon defeat, she'll drop items.
 * In the first encounter, it is possible to "kill" Rachael before meeting back up with Parker in the Cafeteria where she attacks the player for the last time on that part of the ship (the place with the Trish Soda machine that still has power).
 * Rachael seems to have been playable in earlier versions of the game. In "Jessica's Report" Rachael can be seen swimming and being attacked by a Sea Creeper.
