First Story Synopsis
Steve Trevor and Wonder Woman spend the day watching a number of professional athletes compete in their fields and amaze at their skill. At the end of their date, Steve Trevor points out that Wonder Woman is the greatest general athlete in the world and entertains how exciting it would be to see Wonder Woman compete against herself. Wonder Woman quashes this notion, telling Steve she uses her talents for truth and justice only, not for exhibition. Just then Queen Hippolyta calls Wonder Woman back to Paradise Island.
Flying her invisible jet back to her homeland, Wonder Woman learns that it now time for the annual contest to prove that she is still worthy of the title of Wonder Woman. She manages to win both challenges: racing a group of chariots by hopping in a sack, and swimming across a length of ocean against a group of motorboats, while being weighed down with a boat anchor. With the competition complete and Wonder Woman’s title secured, Diana meets with Professor Alpha in the Amazons lab.
The Alpha reveals her new Dimension X transporter that can teleport people into and out of Dimension X. Wonder Woman agrees to help test it out and is transported to Dimension X. Just then she is suddenly transported back, and to the shock of everyone, with another Wonder Woman. This Wonder Woman explains that she is from Dimension X, and tells all assembled that she is far superior to her counterpart in this dimension and offers a challenge to see which one of them is truly worthy of the title Wonder Woman.
A series of tests are organised to see which of the two Wonder Women was the most skilled. The first test would come to see who could remain on top of a gushing geyser. The Wonder Woman from Dimension X manages to win the competition by maintaining her balance on it’s crest while doing a hand-stand. The next competition was to see who could put out a series of giant candles out the fastest. This contest is won by Earth’s Wonder Woman, who puts out all the candles by walking on her hands.
The next challenge would take place in Dimension X, and when the two transport to that world, the Wonder Woman of Earth is shocked to find that her Dimension X counterpart lives in a fairy-tale world. Before they can get to the castle where the third challenge is to take place, they are attacked by an army of giants. The two Wonder Women pool their abilities together to drive off this invading force of giants. However, it is Earth’s Wonder Woman who comes with a solution to defeat their foes: Uprooting a giant tree, she bends it into the shape of a boomerang and tosses it. Unprepared for such a weapon the giants are all knocked out.
Thankful for her counterparts assistance the Wonder Woman of Dimension X is about to lead her Earthen counterpart to the castle when the boomerang comes back. When it threatens to strike the Dimension X Wonder Woman, Diana takes a dive and knocks it out the way. Back on Earth, Queen Hippolyta is worried about her daughters progress and Alpha turns on a view screen to see what is happening in Dimension X. They are delighted to see a ceremony where the Wonder Woman of Dimension X is crowning Diana and proclaiming her as the true Wonder Woman of both worlds.
