With the beginning of the third season, further changes were made to target the show at a teenage audience. The title theme was re-recorded again to give it a disco beat, the use of the robot 'Rover' was increased for comic effect, and episodes began to revolve around topical subjects like skateboarding, roller coasters and the environment (Feld also gave Wonder Woman a "skate-boarder's" uniform, which was also capable of use for training in any "extreme sport" in which she participated). Teenagers or young adults were commonly used as main characters in the plot lines. Eve disappeared from the cast although she is mentioned once or twice. Episodes during this season showed Diana on assignments by herself far more often (particularly outside of Washington DC), and Steve Trevor had become Diana's boss and was seen less. Wonder Woman was also allowed to become a bit more physical in the third season and could now be seen throwing the occasional punch or kick. The writers also came up with several unusual ways for Diana to execute her spinning transformation, the most notable instances occurring in the episode "Stolen Faces" in which Diana makes the change while falling off a tall building, and the season two episode "The Pied Piper" in which she changes while strapped into a spinning chair. Diana also exhibited other powers, particularly in the episode "The Deadly Dolphin", in which she is shown communicating telepathically with animals (reminiscent of the "mental radio" from the comics, which was never shown on the series) and generating bursts of an unknown form of energy to scare away a killer shark. In the final episode produced, the writers attempted a "relaunch" of sorts by having Diana reassigned to the Los Angeles bureau of IADC with a new supporting cast. Though done in anticipation of a fourth season, the revamp was seen only in one episode ("The Man Who Could Not Die"), which set up an assortment of new supporting characters. These included Dale Hawthorn, Diana's new IADC boss, Bret Cassiday (Bob Seagren), a genetically enhanced man who was indestructible (the titular character of the episode), as well as a streetwise youngster named T. Burton Phipps III who inexplicably is allowed to hang out at the IADC. Also added to the cast was a chimpanzee who, like Bret, is also indestructible. This episode was actually the last to be produced and would have
