The series follows the adventure of Cole Evans, who had been staying with a tribe in a jungle for many years, as he tries to find his destiny in the fictitious town of Turtle Cove. He encounters the Animarium, a place that many believed to be a fairy tale. He joins four others who had a common path to become the new leader of the Wild Force Power Rangers.
The Animarium is an island that floats in the sky. It is shaped like a turtle and is the home of the Wild Zords and Princess Shayla, the Rangers’ mentor. (It is unclear how the Rangers travel between the Animarium and the Earth surface, but in one of the last episodes Merrick and Kite are teleported onto the Animarium, so presumably they used the same teleportation throughout the rest of the series.)
The Power Rangers use their powers to defeat the forces of the Orgs, led by one Master Org. As Cole was fond of other animals, he was shocked to discover that the Orgs were literally heartless horned monsters. As the series continues, he finds out the truth about his real parents: his parents, Richard and Elizabeth Evans, were professors at Turtle Cove University, along with a family friend, Viktor Adler, a human reincarnation of the original Master Org. When they were sent to the jungle for research, they discover the remains of Master Org, in which a jealous Adler consumes in order to exact revenge on Richard, who had proposed to Elizabeth before he could. However, Adler goes insane, and kills both Richard and Elizabeth. For a while, their newborn son, Cole, was also presumed dead.
In addition to the annual team-up episodes, Power Rangers Wild Force also had a special episode commemorating it as the tenth incarnation, Forever Red, by having Cole team up with the nine Red Rangers before him, (in order of incarnations, Jason Lee Scott, Aurico, Tommy Oliver, T.J. Johnson, Andros, Leo Corbett, Carter Grayson, Wesley “Wes” Collins and Eric Myers), in order to prevent the remaining generals of the Machine Empire from unearthing and reactivating Lord Zedd’s zord, Serpentera, which had been left buried on the moon.
