Twice-Told-Tales: Alexander the Great - Ally or Adversary

The pivitol year was 331 B.C.E., in an event known as the Battle of Arbela. On both Earths One and Two, the Grecian leader Alexander the Great led his forces into battle against King Darius of Persia along with that monarch's army. Yet on each world, time travelers journeyed back from the 20th century, with the intent of influencing the past to further their future agendas. These twin time masters were Rip Hunter of Earth-One and Per Degaton of Earth-Two.

Rip Hunter and his crew of Jeff Smith, Bonnie and Corky Baxter retrieved an ancient tablet once possessed by Alexander that allegedly revealed the location of Atlantis. However, as they were unable to decipher the bottom line, they quartet piloted their time sphere back to 331. After aiding Alexander and his minions, they were given guidance and where they might find the missing information in another earlier era.

Per Degaton and his minions sought to deprieve the 20th century of all modern technology except that which they themselves possessed, and ascertained the pivitol year to change such history was in 331 during this key battle. Degaton and his forces aided the Persians in their onslaught against the Greeks, and a new timeline resulted in the time tyrant's victory. However, Green Lantern retrieved his Justice Society teammates from the future, and brought them back to the time of Arbela when they allied with Alexander's legion in defeating the Persians. The main future timeline was restored to normal.

While Alexander was treated as an ally by the Justice Society, when he had been brought forward in time with fellow world conquerors by Doctor Doome, the Grecian lord acted as a criminal. Utilizing a batallion of robots, Alexander was thwarted by the Ace Archers known as Green Arrow and Speedy, who along with their partners in the Law's Legionnaires helped track down and defeat the five tempermental tyrants of the past. 

On Earth-One, that Green Arrow in his identity as Oliver Queen purchased an ancient iron statute known as the Emperor Eagle, originally bequeathed to Alexander shortly before his death. This led Arrow and fellow Justice Leaguer the Batman into conflict with the Joker and Two-Face, who stole the statue for the ruler of the country where it originated.
