Directly after being sculpted from clay, several Olympian gods granted attributes to Diana.
Granted by Demeter (Goddess of the Earth). Diana is literally as strong as the Earth because of her link to the planet granted to her by Demeter. She is said to be "stronger than Hercules". Wonder Woman is as strong as Superman himself and able to physically outmatch other beings such as Supergirl.
Granted by Demeter (Goddess of the Earth). Diana possesses a high resistance to damage and magical attacks. Her resistance to injury is not quite as great as any of the above mentioned metahumans. However, due to her vast threshold for pain and her amazon ability to heal at a superhuman rate, this easily makes up for the difference. She has withstood considerable bludgeoning damage in the form of hand to hand combat with metahuman opponents such as Superman and Captain Marvel. She has considerable resistance to human weaponries, though this is not absolute; Bullets can cause minor to moderate injury, but never life threatening.
Granted by Hermes (the Messenger God). Wonder Woman is capable of unassisted flight by gliding on air currents.
Granted by Hermes (the Messenger God). She is able to think, react and move at superhuman speeds. According to Flash, she can easily keep up with him if he is at regular cruising speed (but not at top speed).
Granted by Hermes (the Messenger God). Wonder Woman's reflexes are far beyond the limitations of the finest human athletes. She has been able to react to a barrage of gunfire from multiple opponents at once unharmed. Batman noted that her reflexes are superior to that of Superman.
Wonder Womans's agility is far beyond that of even an Olympic level athlete, as is her balance and coordination.
Wonder Woman can last a great deal of time in any fight and with virtually anyone. She has held her own in combat with foes as powerful as a Doomsday clone. She doesn't tire out, as her body produces no lactic acids in her muscles.
Enhanced Healing Factor
Granted by Demeter (Goddess of Earth). Like the Earth, Diana is constantly renewing herself, allowing her to quickly heal mild to moderate injuries at an amazing rate. Her normal regenerative abilities allow her to recover from injury within seconds to minutes. She possesses an incredible immunity from poisons, toxins, as well as disease.
Oneness With Fire
Granted by Hestia (Goddess of the Hearth). Apparently making her a focus of truth.
Granted by Athena (Goddess of Wisdom). "The Sight of Athena" apparently grants her increased insight. For example, Diana can often detects others' emotions, and is now so fully immune to Doctor Psycho's illusions that she usually is not even aware of what illusions he is attempting to project.
Granted by Artemis (Goddess of the Hunt). Ability to communicate with all forms of animals (including dinosaurs) and her presence alone can bring a raging beast to a calm standstill. She is also able to directly command wild animals when needed. She used bald eagles to distract Superman after defeating him in battle once.
Granted by Artemis (Goddess of the Hunt). Eyesight, hearing, taste, touch and smell.
She also possess the "Hunters Eye" which allows her to always hit her mark. She can see to far greater distances than any normal human. After a short period of blindness, Athena bound her own vision to her champion, not only restoring her sight, but granting her further insight as well.
Enhanced Sense of Smell
On occasion, Wonder Woman can literally leave the planet through meditation. She did this to rescue Artemis when she was in hell, and has even conversed with the Greek Gods on occasion.
Hand-to-Hand Combat (Advanced)
Diana is the finest warrior ever born among the Amazons of Themyscira. She is a master of armed and unarmed combat, proficient with nearly every weapon ever made (especially the bow and the javelin) and the exotic martial arts styles of the Amazons. Batman once remarked that Wonder Woman is the best melee fighter in the world.
Wisdom of Athena
Granted by Athena (Goddess of Wisdom). Diana possesses great wisdom and intelligence, though the degree varies from author to author. She is among the smartest and wisest members of the Justice League of America, along with the Martian Manhunter and Batman.
Diana has exhibited heightened proficiency with languages, being able to speak her native Themysciran, Ancient and Modern Greek, English, Spanish, Portuguese, French, Mandarin Chinese (she expressed "difficulty" with the tones of Cantonese during an interview with Lois Lane), Russian and Hindi. Plus, through precise muscle control, she can mimic other people's voices for short conversations (on the telephone). It is more difficult, for her to mimic a mans voice than another woman's voice.
Master Tactician and Strategist
Granted by Athena (Goddess of Wisdom). Diana is an accomplished strategist and tactician, trained in the arts of leadership, persuasion and diplomacy, and possesses a great deal of courage as well. She is a gifted leader.
Expert pilot. Can fly the Invisible Jet with ease.
Diana is an expert at using her tiara as a boomerang.
