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.
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.
Receiving a signal from Chief, she infiltrates Ludendorff's base. She and General Ludendorff fight each other where Diana kills him. Thinking that killing Ludendorff would solve the problem, she gets confused when she sees the German soldiers loading the weapons onto the planes thinking that humankind is corrupted and it doesn't deserve her help.
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.
Indomitable Will: Wonder Woman has tremendous determination and strength of will. She refuses to ever give up, even when placed against seemingly insurmountable odds. Hence, despite the Germans invading Themyscira having far superior firepower, despite the extreme danger of German firepower in-between World War I trenches, despite having to fight the stronger and seemingly unstoppable Doomsday, despite having to battle the mighty Ares right after witnessing Steve Trevor's death, Wonder Woman promptly rose up, overcame her negative emotions, and kept on fighting, persisting until she eventually managed to gain the upper hand. Indeed, her indomitable spirit gave a renewed hope to the Wonder Men and inspired them past the point of purely monetary interests, with Chief resolving to no longer be neutral in the war and believing her story of the Olympians, Sameer finally admitting his passion for acting, and even the depressed Charlie struggling with PTSD finally beginning to sing again for the first time in years. When humanity's inherent potential for evil was revealed to her by Ares, Wonder Woman, while initially taken aback, ultimately rejected the prospect of alliance with Ares against them, even if that were to mean missing out on "paradise" on Earth, and instead courageously confronted him as the god killer. When seemingly beaten by Ares (who was only growing more powerful from her violence, rage, and hatred) and overcome by the weight of his words and the devastation of Steve's death, Wonder Woman recalled his great love for and undying belief in her, and was thereby able to muster enough willpower and love to overcome her violent emotions and defeat Ares. While mostly stepping away from superheroism for 100 years (emotionally crippled at her inability to save the Belgian villagers and Steve, and by seeing the ensuing "century of horrors"), Wonder Woman didn't entirely lose hope, and it was fully reignited again when she witnessed the self-sacrificing death of another selfless superhero, Superman (who combined the phenomenal godly might of Ares with the self-sacrificing morality of Steve Trevor), giving her enough faith to help Batman found the Justice League. During the League's battle against Steppenwolf's forces, Wonder Woman was able to inspire confidence into the inexperienced Flash and Cyborg, assuring them that they wouldn't need to fight the Apokoliptan invasion alone.
While Superman watched out for Zod, Diana visited the deserted Themyscira to speak to her mother, still a clay statue. In her absence, a demon from Tartarus had escaped from its prison and roamed free on the island. Wonder Woman destroyed the creature and sealed the gates to Tartarus with her lasso. Leaving the island, she received word from Batman that Superman was engaging Zod and Faora in battle. Reaching Superman’s side, Wonder Woman steadily overwhelmed Faora until Zod threatened Superman’s life. Wonder Woman was forced to let the criminals go.

Superhuman Senses: Wonder Woman, due to her demigoddess physiology, has all of her senses superhumanly enhanced, much like those of Superman. This allowed her to clearly see Steve Trevor from miles away when his plane crash-landed near Themyscira. While talking to Bruce Wayne outside his lake house, Wonder Woman was able to spot Cyborg behind a tree spying on them.
