She is able to astrally project herself into various lands of myth. Her physical body reacts to whatever happens to her on the mythical astral plane, leaving her body cut, bruised, or sometimes strengthened once her mind and body are reunited. She can apparently leave the planet through meditation and did this once to rescue Artemis while she was in Hell.
Diana is a very kind, loving, compassionate, and strong-willed person, who, while initially somewhat naive, has become all the wiser through her time in Man's World. An outspoken egalitarian, she fights for what she believes in and generally for the betterment of mankind through love and mutual understanding, as taught to her by her mother and fellow Amazons. Growing up, Diana also proved herself headstrong and determined to do what she wanted, such as training in hand-to-hand combat under her aunt Antiope's tutelage despite her mother initially forbidding it. In this way she is quite stubborn; if she believes something is the right thing to do, then she will do it - as evidenced by her attempt to leave Themyscira without her mother's permission and insistence in attending Ludendorff's gala despite Steve telling her not to. Alongside her kindness and compassion, however, Diana was also a very naive idealist when she first arrived in "Man's World", blindly believing that all men were corrupted by Ares and that the World War I Central Powers would simply abandon their sinister ways if she killed him. This blind naivety also translated to explicit indignation whenever she was treated with disrespect due to her status as a woman, such as when she was ignored by members of the War Office. Alongside this, Diana also voiced her opinions rather bluntly upon her arrival, such as when she perceived Etta Candy's job as Steve Trevor's secretary to be akin to slavery (which earns Diana Etta's admiration). Despite her outspokenness and behavior in Man's World, however, Diana remained caring and compassionate, as demonstrated by her initially rocky relationship with Charlie and willingness to step into No Man's Land to save the village of Veld.
As her injuries healed, Wonder Woman and her friends spent some time on New Genesis. She spoke to Highfather, who agreed to let her return to Earth. As soon as Diana and her friends returned to Earth, Orion decided to go with them. Arriving to London, they realized the First Born had wrecked the entire city and killed Lennox. The First Born summoned an army of hyena men to kill the intruders but Ares arrived to help Wonder Woman in the fight.
Steve Rose in The Guardian criticized the film for failing to explore the material's potential for "patriarchy-upending subversion". Peter Travers of Rolling Stone criticized the film's over-reliance on exposition: "Wonder Woman is hobbled by a slogging origin story and action that only comes in fits and starts. Just when Gadot and director Patty Jenkins...are ready to kick ass, we get backstory."
"Gas was intended to win the war. On that much Wonder Woman is absolutely right." said David Hambling in Popular Mechanics. Rachel Becker of The Verge stated that despite the scientific liberties of using a "hydrogen-based" chemical weapon as a plot device, the film succeeds in evoking real and horrifying history. "First off, mustard gas is such a horrible, terrifying weapon, it doesn't need to be made more potent. But if you were a chemist bent on raining destruction on the Allied forces, you wouldn't do it by replacing the sulfur atom in mustard gas with a hydrogen atom. You'd know that sulfur is the linchpin holding together this poisonous molecule."
At the end of Infinite Crisis, Wonder Woman temporarily retires from her costumed identity. Diana, once again using the alias Diana Prince, joins the Department of Metahuman Affairs. Donna Troy becomes the new Wonder Woman and is captured by Diana's enemies. Diana then goes on a mission to rescue her sister, battling Circe and Hercules. Diana defeats the villains, freeing Donna and takes up the role of Wonder Woman again. Circe places a spell on Diana, which renders Diana into a normal, powerless human being when in the role of Diana Prince; her powers come to her only when she is in the role of Wonder Woman.
The demon Neron engaged Diana in battle and managed to kill her. The Olympian Gods granted Diana divinity and the role of the Goddess of Truth who started to reside in Olympus; her mother Hippolyta then assumed the role of Wonder Woman and wore her own different incarnation of the costume. In Wonder Woman Vol. 2 #136, Diana was banished from Olympus due to interfering in earthly matters (as Diana was unable to simply watch over people's misery on Earth). She immediately returned to her duties as Wonder Woman, but ran into conflicts with her mother over her true place and role as Hippolyta seemed accustomed to her life in America. Their fight remained unsolved, as Hippolyta died during an intergalactic war. Themyscira was destroyed during the war, but was restored and reformed as a collection of floating islands. Circe later resurrected Hippolyta in Wonder Woman Vol 3 #8.
Perhaps due to her Amazonian background, Diana greatly respects other noble selfless warriors, as evidenced when she attended Superman's funeral in Smallville and spoke of how he had been much more than a soldier (adding to what Batman said about Metropolis burying an empty casket). As a result of her great posthumous respect, she was, therefore, more than willing to aid Batman in honoring the heroic death of Superman, by helping round up the metahumans from Lex Luthor's files to form a team of superheroes (later known as the Justice League) to protect the world from the imminent mysterious alien invader Steppenwolf and his Parademon minions after Superman's death left the world vulnerable.
