a "Charlie's Angels-like" character who is heard but never seen. Diana and Steve would go out and work the field while Joe assisted from the office. The Atkinson character was dropped after the ninth episode of this season, and Steve was given a promotion, becoming IADC Director, and Diana's boss, in the process. This promotion for Steve Trevor meant that Lyle Waggoner was seen less in subsequent episodes for the remainder of the series' run. In this season, the computer IRAC (Information Retrieval Associative Computer), more informally known as "Ira", was introduced: its first appearance is in season 2, episode 1, where Diana introduces her Diana Prince identity into its records, over IRAC's protests. Ira was the IADC's super-intelligent computer, who deduces that Diana Prince is really Wonder Woman, although he never shares this information with anyone, except Diana herself. Saundra Sharp joined the cast as Eve, Steve's assistant (the job held by Diana at the start of the season). Towards the end of the season, in the episode "IRAC is Missing", a small mobile robot called Rover was added for comic relief. An offshoot of IRAC who performs duties such as delivering coffee and sorting mail, Rover speaks with a high-pitched voice, occasionally makes "Beep Beep" sounds and, like IRAC, is aware that Wonder Woman's secret identity is Diana Prince. A more subtle change concerned Wonder Woman's intonation. In the first season, a mild version of the Mid-Atlantic accent, synonymous with the Golden Age of Hollywood, was used. For the second (and third) season, Wonder Woman's intonation sounded Southwest American, reflecting the region where Lynda Carter herself was born and raised (Phoenix, Arizona). Whether this change was done for the purpose of modernizing the series is unknown. The theme song was re-written to remove references to the Axis, reflecting the series' new present-day setting, and the action depicted in the opening's animated comic book panels was similarly updated. Beginning with the episode "The Man Who Made Volcanoes", the opening title sequence was changed again to an instrumental and more traditional "action scenes" opening. The animated stars used before and after commercial breaks were dropped. The producers of Wonder Woman generally maintained her no-kill policy, although there were exceptions: In the episode "Anschluss '77" she is forced to destroy a clone of Adolf Hitler. Another episode made reference to a villain who was believed drowned following a previous unseen encounter
