Wonder Woman gets a little jealous with Supergirl's arrival, believing she is trying to catch everyone's attention. When she realized that Supergirl is actually a better superhero because she looks up to Wonder Woman, they became friends and Wonder Woman helps to train Supergirl. She is among the heroes to battle against Granny Goodness and the Female Furies. She is voiced by Grey Griffin.
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.
I thought George's one "mistake" in rebooting Wonder Woman was making her only 25 years old when she left Paradise Island. I preferred the idea of a Diana who was thousands of years old (as, if I recall correctly, she was in the TV series). From that angle, I would have liked to have seen Diana having been Wonder Woman in WW2, and be returning to our world in the reboot. Not having that option, I took the next best course, and had Hippolyta fill that role.
Wonder Woman continued to use the plane for super speed, outer space, and multi-dimensional transport up until the unpowered era of Diana Prince. When Wonder Woman resumed superpowered, costumed operations in 1973, she continued to use the jet as before, but did glide on air currents for short distances. At one point, Aphrodite granted the plane the power to fly faster than the speed of light for any interstellar voyages her champion might undertake. Thanks to tinkering by gremlins, the Plane even developed intelligence and the power to talk. The plane proved a good friend, eager to help his "mistress" and her loved ones in any way possible. It got along especially well with Steve Trevor.
One of the events that led to Infinite Crisis was of Wonder Woman killing the villain Maxwell Lord in Wonder Woman (vol. 2) #219. Maxwell Lord was mind-controlling Superman, who as a result was near to killing Batman. Wonder Woman tried to stop Superman, Lord (who was unable to mind control her) made Superman see her as his enemy Doomsday trying to kill Lois Lane. Superman then attacked Wonder Woman, and a vicious battle ensued. Buying herself time by slicing Superman's throat with her tiara, Wonder Woman caught Lord in her Lasso of Truth and demanded to know how to stop his control over Superman. As the lasso forced the wearer to speak only the truth, Lord told her that the only way to stop him was to kill him. Left with no choice, Wonder Woman snapped Lord's neck and ended his control over Superman. Unknown to her, the entire scene was broadcast live around every channel in the world by Brother Eye. The viewers were not aware of the entire situation, and saw only Wonder Woman murdering a Justice League associate. Wonder Woman's actions put her at odds with Batman and Superman, as they saw Wonder Woman as a cold-blooded killer, despite the fact that she saved their lives.
