The Invisible Plane was a creation of Diana's during her younger years on Paradise Island. She created it to be an improvement on her mother's planes which would be shot down in Man's World. The result of her innovation was an invisible plane that could fly at terrific speeds silently and not be detected by hostile forces. Initially, it was portrayed as being transparent.
The American theme of Diana's costume was explained by Pérez in the Challenge of the Gods storyline in which Diana engaged in a series of trials arranged by Zeus as punishment for refusing his advances. Diana met the spirit of Steve Trevor's mother, Diana Trevor, who was clad in armor identical to her own. Trevor revealed that during World War II she had crashed on Themyscira while on duty as a U.S. Army pilot. She blundered into an Amazon battle against Cottus, a multi-armed demon, at the portal to the underworld. Trevor was drawn into the battle, although she was armed only with her side arm. She wounded the beast before suffering a mortal blow, allowing the Amazons to reseal the portal.
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.
Voiced by Vanessa Marshall. A movie where an alternate version of Lex Luthor travels to the mainstream universe to ask the JLA for help regarding the alternate version of Lex's universe. The Crime Syndicate of America runs their world through intimidation and blackmailing the USA's president (Slade Wilson). Wonder Woman's counterpart is Superwoman, and she equals Wonder Woman in every way.
When Diana returns she takes on the persona of Diana Prince, now a secret agent and member of the Department of Metahuman Affairs. She is partnered with Nemesis and the two report to Sarge Steel. Her first assignment is to retrieve her sister Donna Troy, who has been kidnapped by several of her most persistent enemies; their powers have been augmented by Circe. After this is accomplished, Diana takes back the title of Wonder Woman.
