Theresa Chasar (Doom 3)

Theresa Chasar was one of the few female UAC employees in Doom 3. According to her PDA, she was involved in research with other UAC scientists on the Plasma gun. She was also friends with Dr. Elizabeth McNeil. Being one of the few women on Mars, she was forced to put up with a considerable amount of unwanted flirting from her male co-workers, particularly her boss Lloyd Renstrom. This had its advantages though, as her colleagues were always eager to assist her in her work.

During the Enpro level, the player can hear a female voice crying. When the player enters Theresa's office where she is sitting, a cutscene takes over in which Theresa pleads for help before abruptly turning away with a demonic snarl. Before the Doomguy can do anything, however, a Lost Soul suddenly tears itself out of Theresa's head, ripping out her spinal cord, and attacks the player.

Many more Lost Souls are encountered during the game, although this is the only time when one is seen to originate from a living human. How exactly the Lost Soul got to be inside of her in the first place is not known.

Weapon Research
''This is the audio log of weapon analyst Theresa Chasar, dated November 3rd, 2145. I am pleased to report that the preliminary tests on the ammo storage in the new Mach 3 Plasma Gun has far exceeded our expectations. We've realized a full 50% gain in the storage capacity of ammo packs as a result of utilizing techniques engineered in the Alpha Labs molecular compressor. I believe with the ongoing compaction research we will reach our goal of 3 times the plasma storage currently available in standard ammo packs.''

''I would also like to mention that all of the employees here at EnPro Plant have been very helpful and quite eager to accommodate all of my requests. For security reasons I've locked the Plasma Gun and the extra ammo in Locker 063 with the door code 972. End of log.''

Theresa,

''Please take a few minutes in the next day or so to create an audio report based on your plasma storage findings. The board is looking forward to hearing about your accomplishments.''

''As you know, security has been tight lately with all the accidents and as a result we can't be too careful. Please make sure you lock up your test weapon and add the cabinet code into your report.''

Great Job,

Lloyd

Your Work (11-05-2145)
Theresa,

''Hope you like your new office. I think you'll find it much easier to concentrate on the plasma gun project without those dweebs in engineering drooling all over you. How pathetic, right?''

''Anyway I'll be down there from time to time if you ever want to talk or get something to eat. You're probably sick of hearing it, but I think seeing you every day is more valuable to me than any amount of money I've gotten from working here. Believe me, being a supervisor I make a lot!''

Your pal,

Lloyd

''I know what you're talking about, when I was still there I felt like I was the only woman surrounded by a bunch of drooling men. I miss the work but I don't miss that place, I feel like I'm lucky to be out of there.''

Keep your eyes open for trouble; I don't trust some of the executives up there.

I can't wait to see you back on Earth when your research is completed.

Your Friend,

Liz

Liz,

''Lloyd has really outdone himself this time. He's moved me into the office next to the trench in Enpro. Does he really think by moving me to the most remote office on this wretched base that I'll be more attracted to him? Wait...it might be working. Being isolated for this long is getting to me. I'm a chatter-box whenever I get the chance to talk to a real person.''

Ok, I've got to get back to work.

Trivia

 * Theresa is the only female character to be seen in Doom 3.
 * Many players mistakenly believe that Theresa's head tears itself from her body and transforms into a Lost Soul (in part due to the Lost Soul's face having a vaguely female appearance). However, if one views the cutscene in slow motion, they will see that the Lost Soul actually bursts out of Theresa's head. Also, when gameplay resumes, if the player looks at her corpse closely, it's clear that her head, although badly destroyed, remains attached to her body.
 * Theresa is named after the sister of Tim Willits, the co-owner of id Software.
