Before Crisis on Infinite Earths there were two Wonder Women: the first one lived on Earth-Two; the second, on Earth-One.
Aphrodite, the goddess of love and beauty, blessed Diana with great beauty and a loving heart.
Pallas Athena, the goddess of wisdom and war, granted Diana great wisdom, intelligence, and military prowess.
Athena's gift has enabled Diana to master over a dozen languages (including those of alien origin), multiple complex crafts, sciences and philosophies, as well as leadership, military strategy, and armed and unarmed combat.
She can mimic voices, although it is more difficult for her to mimic a man's voice.
In the television series, her magic belt allowed her to retain her powers when she was not on Paradise Island; removing it weakened her.
With the inclusion of Wonder Girl and "Wonder Tot" in Diana's back-story, writers provided new explanations of her powers; the character became capable of feats which her sister Amazons could not equal. 1) #105 reveals that Diana was formed from clay by the Queen of the Amazons and was imbued with the attributes of the Greek and Roman gods by Athena — "beautiful as Aphrodite, wise as Athena, swifter than Hermes, and stronger than Hercules."Wonder Woman's Amazon training also gave her limited telepathy, profound scientific knowledge, and the ability to speak every language known to man and beyond. Although Wonder Woman's mythos was returned to its original interpretation between 19, new abilities were added: super breath, the ability to blow jet streams or transform water into snow, which apparently came from Hercules; ventriloquism; imperviousness to extremes of heat and cold; the ability to ride the air currents as if flying, even sensing air updrafts with her fingers; telepathy, including the ability to project images; microscopic vision; the ability to vibrate into another dimension; the ability to bestow wisdom to other beings; the ability to throw her tiara with such skill it could stop bullets; and others, according to the Encyclopedia of Comic Book Heroes.She has been observed assisting in preventing large chunks of the Moon from crashing onto the Earth, supporting the weight of bridges, or hefting entire railroad trains.Although sometimes stated as possibly being physically weaker and slower than, for example, Superman, Diana's superior warrior training more than makes up for it, along with strength drawn from the earth itself, she is able to overpower beings such as Supergirl, and hold her own against beings such as Superman and Captain Marvel and on some occassions, even beating them in combat.She was able to make a coin into a bridge with her strength, or drill through a mountain within seconds, as well as hurl spaceships with enough accuracy she could bowl over a whole fleet. She was even able to flip straight over while nearly paralyzed, and split a tree falling on her with her Amazonian boots.Kanigher showed Wonder Woman as a preteen able to lift whales, push a ship away from a whirlpool, and also as a toddler able to blow so hard on her birthday cake that she sent it into orbit.She is durable enough to survive the rigors of space until she runs out of breath.
