Doctor Olsen was a physician who lived and worked in Southern California during World War II, a competent enough surgeon who was nevertheless outclassed by Dr. Sam Sabuki. A bigot in addition, Olsen naturally welcomed his rival's removal from the hospital staff and the community too when all Japanese-Americans were interred during the war. His envy was such that, when the Invaders brought a severely injured Toro cross-country for treatment, he kept mum about Sabuki and his whereabouts, which Bucky had to be alerted to by Olsen's reluctant aide, Nurse Gimble.
Even as Toro's life slipped further away, Dr. Olsen refused to even consider allowing Sabuki to operate, and angrily dismissed Gimble when she attempted to reason with him. Thankfully, Toro was kidnapped from the hospital shortly thereafter, thus allowing Dr. Sabuki the opportunity to save his life.
