After the departure of Thomas in 1983, Dan Mishkin took over the writing. Mishkin and Colan reintroduced the character Circe to the rogues gallery of Wonder Woman's adversaries. Don Heck replaced Colan as artist as of issue #306 (Aug. 1983) but sales of the title continued to decline. Shortly after Mishkin's departure in 1985 – including a three-issue run by Mindy Newell and a never-published revamp by Steve Gerber – the series ended with issue #329 (February 1986). Written by Gerry Conway, the final issue depicted Wonder Woman's marriage to Steve Trevor.
The Crisis on Infinite Earths crossover of 1986 was designed and written with the purpose of streamlining most of DC's characters into one more-focused continuity and reinventing them for a new era, thus Wonder Woman and Steve Trevor were declared to come from the Earth-Two dimension, and along with all of their exploits, were erased from history, so that a new Wonder Woman character, story and timeline could take priority.
Ares told Diana that he had been imprisoned by the other Gods of Olympus and bound in chains that were secured by Aphrodite through the power of her love. He also told her that years ago, Phobos and Deimos had implanted false memories of Themyscira into her mind, and these had caused her to imagine aspects of her past that had never happened in reality. Meanwhile, Phobos and Deimos entered Themyscira and battled with the Amazons. Diana knew what she had to do, and called Ares to unite her with Phobos and Deimos. He teleported them to her, and using her Lasso of Truth, Wonder Woman bound them through the power of her unconditional love for them, as Aphrodite had done to Ares. With the twin gods defeated, Diana attempted to leave Ares' prison along with Veronica and Izzy, however Izzy's essence had been attached to the realm and could not return to Earth. Izzy was forced to either live out the rest of her days in the prison or live in Themyscira as an Amazon for eternity. She chose the latter and Veronica said goodbye to her daughter. Diana was briefly reunited with her mother, for the first time since she left the island.
Since her attack on Veronica Cale, Cheetah had been captured by Cale and held in the basement of Empire Industries, where she was being experimented on by Doctor Poison. Cheetah suddenly dropped into a coma, before waking and massacring Empire Industries' staff, while screaming about the return of the so-called 'Dark Gods'. She attempted to kill Cale once again, but was restrained due to the timely intervention of Wonder Woman. Steve Trevor informed Diana that all over the world, people had begun acting strangely and warning of the Dark Gods. As she flew through the skies of Washington, she was suddenly attacked by a deranged Supergirl. After a lengthy battle, Wonder Woman was able to defeat Kara and restrained her in the Lasso of Truth, which knocked her unconscious. Jason returned after learning from the Fates that the armor that had been gifted to him by the gods was originally created for Diana, but had been mistakenly given to Jason after Zeus' death. It also allowed Jason to channel the power of any member of the Greek Pantheon, though he could only use one god's powers at a time. Jason began to explain his discoveries to Diana, but they were interrupted by a group of giant monoliths appearing in the sky, which began to activate. As soon as the siblings began to investigate, Wonder Woman was taken by a pair of Star Sapphires who needed her assistance due to an emergency on Zamaron. As Diana was forcefully teleported, Jason was left alone before the activating monoliths.

Although the Amazons were back to normal, Hippolyta was still a statue, and Hera could not restore her back to life. Zola wanted to leave the island, but Diana told her she and her child were safer with the Amazons. Diana addressed the Amazons and declared her intentions to end the Amazons' isolation and that every Amazon must protect Zeke, a male child.
Wonder Woman experienced significant changes from the late 1950s through the 1960s during the Silver Age of Comic Books. Harry G. Peter was replaced by Ross Andru and Mike Esposito in issue #98 (May 1958), and the character was revamped as were other characters in the Silver Age. In Diana's new origin story (issue #105), it is revealed that her powers are gifts from the gods. Receiving the blessing of each deity in her crib, Diana is destined to become as "beautiful as Aphrodite, wise as Athena, stronger than Hercules, and swifter than Mercury". Further changes included the removal of all World War II references from Wonder Woman's origin, the changing of Hippolyta's hair color to blonde, Wonder Woman's new ability to glide on air currents, and the introduction of the rule that Paradise Island would be destroyed if a man ever set foot on it.
The Silver Age format for comic books also did not generally favour a lot of story arcs, or at least, not memorable ones. In this period though the character did undergo some consistent changes as she battled a variety of common foes including Kobra, but the changed format gave her the ability to develop more as a character. The silver age stories of Wonder Woman can be broken into a few general arcs – the depowered stories (in the mod girl phase), undergoing tests to re-enter the Justice League of America, a golden age story about her work during the Second World War, her adventures as an astronaut for NASA, the hunt for Kobra, and eventually the return of Steve Trevor and the internal politics of working at the Pentagon. The most famous story which she was involved with at this time was “For the Man Who Has Everything”, a story focused on Superman, but also involving herself and Batman. The first major story arc which she was part of was Crisis on Infinite Earths, which also ended her silver age appearances.
