Diana is depicted as a masterful athlete, acrobat, fighter and strategist, trained and experienced in many ancient and modern forms of armed and unarmed combat, including exclusive Amazonian martial arts. With her godlike abilities of incalculable superhuman strength, nigh-invulnerability, speed, flight, healing factor and semi-immortality, Diana’s fighting prowess is enhanced. In some versions, her mother trained her, as Wonder Girl, for a future career as Wonder Woman. From the beginning, she is portrayed as highly skilled in using her Amazon bracelets to stop bullets and in wielding her golden lasso. Batman once called her the "best melee fighter in the world". The modern version of the character is known to use lethal force when she deems it necessary. In the New 52 continuity, her superior combat skills are the result of her Amazon training, as well as receiving further training from Ares, the God of War, himself, since as early as her childhood. The Golden Age Wonder Woman also had knowledge in psychology, as did her Amazon sisters.
This new era of the comic book was influenced by the British television series The Avengers, with Wonder Woman in the role of Emma Peel. With Diana Prince running a boutique, fighting crime, and acting in concert with private detective allies Tim Trench and Jonny Double, the character resembled the Golden Age Black Canary. Soon after the launch of the "new" Wonder Woman, the editors severed all connections to her old life, most notably by killing Steve Trevor.
The Lasso of Truth forces people to tell the truth. It was forged by Hephaestus from the Golden Girdle of Gaea that Antiope had once worn. It is able to restore people's lost memories get rid of illusions or cause illusions to those it holds and heal the holder's body cure insanity and protect people who are in close proximity to it from magical attacks. In the golden age version the lasso could also take on a rigid form and hold people aloft from a great distance away. During these eras, the lasso also forced those who were bound by it to act as the holder demanded. This trait also affected Wonder Woman. A non-combat application of the lasso is that it can be used to change Diana's clothes as long as those clothes are "in the right frequency" as the lasso. Although this was a plot device used more often in the golden and silver age in has been used on occasion in modern comics as for instance one time Diana transformed into a Miss America costume. The lasso is essentially indestructible, and can be offensively used in combat to incapacitate, and even attacking their souls.
