UTK/SO/UTK2 Main characters

Derek Stiles

(Age: 26) (born 1992) - Derek Stiles is the main character and a surgeon at Hope Hospital (and later, Caduceus USA). He is just beginning to realize his potential. Dr. Stiles is a laid back type of person, and didn't take his patients seriously until Angie came along. Derek is a "descendant" of the Greek god of medicine, Asclepius, and is gifted with extreme concentration, an ability referred to as the "." In the first two games of the series, Derek fights against the deadly G.U.I.L.T. strain of viruses. He desires to help people because his father died of an illness when he was young (And later, by remembering a doctor telling him that he can't operate on his father). In Trauma Center: Second Opinion, he becomes Dr. Weaver's patient after being infected by Kyriaki and Paraskevi after an operation on a patient.

In "", Derek and Angie make a brief appearance in one of the later cutscenes in the game, notably as representative of Caduceus Japan (the end of UTK2 suggests his transfer), and assist Markus Vaughn and Valerie Blaylock in the last Challenge operation of the game, in which the player must treat simulated patients that are infected with not only Stigma, but GUILT as well.

Nozomi Weaver

(Age: 29) (born 1989) - Nozomi is introduced during the 'Z' episodes of Trauma Center: Second Opinion. Originally a doctor in Japan, her ability to use the Healing Touch made her known as the Devil Doctor because of its supernatural effect. Oddly she has the initials of NW like Derek has DS. NW is probably referring to Nintendo Wii, the only playable console for Trauma Center: Second Opinion. She lost her license in Japan before Delphi gave her a new name and had her work to help those they infected with GUILT that they wanted to use for further tests. She is playable in the 5 'Z' episodes, and the 4 operations during Chapter 6 and the X episodes. Her healing touch differs from Derek's, allowing her to raise a patients' vitals by receiving "Cool", "Good", or "OK" ranks in her actions, although in the 7th X mission against Savato, where using the Healing Touch to stop time completely is required to complete the operation, she discovers that she can use it the same way as Derek. After Delphi is found and eliminated, she offers samples of immature GUILT viruses to work for Caduceus Europe in exchange for her freedom. Eventually, her real name in the North American version is revealed to be Naomi Kimishima.

Angie Thompson

(Age: 21) (born 1997) - Angie Thompson is a young nurse that works as Derek's assistant. She is part German and was raised by a very well-educated family. She may seem a bit critical at times, but she is truly trying to help Dr. Stiles work to his full potential. Angie is also a smart thinker when it comes to medical situations. She usually can keep a grip on things, but occasionally gets caught up in the moment. Despite not being impressed with him early in the first game, she has been shown to harbor romantic feelings for Derek Stiles, with a relationship strongly implied at the end of UtK2.

UTK/SO/UTK2 Secondary Characters

Hope Hospital staff

Mary Fulton (age: 39) (born 1979) - The senior surgical assistant for Hope Hospital. She is a nurse whom helped Derek learn the basics of surgery. She moved away from Hope Hospital, where Angie took her place. Mary is seen later in the game, wondering if Dr. Stiles is alright after seeing footage of his operations on tape.

Robert Hoffman (age: 62) (born 1956) - Dr. Hoffman was an exceptional surgeon who stopped practicing in his 40's after a problem, which is never fully explained in the games (though it hints that he failed a major operation using the Healing Touch), where it is referred to as "the accident". He's now the director of Hope Hospital. He is also gifted with the Healing Touch but seems reluctant to talk about it. After the death of Richard Anderson he becomes the head director of Caduceus USA. Later in the game, after an outbreak of GUILT, he returns to surgery and uses his Healing Touch, which is described as being able to make his surgery amazingly quick. This implies he holds the same Healing Touch as Derek. In the last mission of Trauma Center: Second Opinion, he is operated on by Stiles and Kimishima after being infected by a stronger Savato strain. During Under the Knife 2, Dr. Hoffman continues his work as the head director of Caduceus USA. He sends Derek back to Hope Hospital when Derek loses his Healing Touch realizing that Derek may be going though the same thing he went though.

With the help of Dr. Stiles, he created the cure for the Tetarti (Τετάρτη) and Pempti (Πέμπτη) strains of GUILT, and helps him defeat Paraskevi.
