Indiana Jones meet Montana Mason

Montana Mason. Indiana Jones. Ace archaeologist achieving amazing acts of archaeology. These counterparts were legends on their respective Earths, albeit legends spoken in hushed tones and later mutated when other larger-than-life legends overtook them. Nevertheless, Montana and Indiana set the tone for noble discovery that later generations would imitate when uncovering astounding artifacts of the past.

On Earth-One, Montana trained his young son Rex to follow in his footsteps, although over time the father and his child deviated in their methods and goals. While the elder Mason sought to share his forgotten finds with the world, his son Rex had a far less benevolent nature, as the lad found opportunity to cash in on his prized treasures to increase his own personal fortunes.

On Earth-Two, Indiana was trained by his father, Henry Jones Senior who like him had similar noble intents in their archaeological work. However, whereas the father was more scholarly and reserved, his son was far more daring and adventurous. At times, the young Indiana became overzealous at protecting his fabled finds from those who wished to expose them.

Rex Mason eventually entered into the employee of wealthy Simon Stagg, and quickly fell in love with his daughter Sapphire. This embittered Stagg to Mason, motivating Simon to trick Rex into entering an ancient Egyptian tomb where he was irradiated by the meteorite stored with the Orb of Ra scepter. This transformed Rex into the elemental man known as Metamorpho, leading to his permanent severance from his own humanity and from any further relationship with his father. Rex never had further interactions with Montana, as the two Masons parted their separate ways.

Back over on Earth-Two, Indiana Jones had a professional rivalry with his fellow archaeologists Carter “Hawkman” Hall and his wife Sheira “Hawkgirl” Hall, while apparently knowing the Winged Warrior’s double identity. Whether he knew of Hall’s ancient ancestry as a 20th century descendant of Egyptian Prince Khufu is unknown, nor if he was aware of Khufu’s memories asserting themselves within Carter on occasion. This Khufu and his wife Princess Shiera were the counterparts of Rex Mason and Sapphire Stagg, the son and daughter-in-law of his doppelgänger Montana Mason. However, Indy was known to have explored the various pyramids and tombs in Egypt’s Valley of Kings, and very well may have been present when fellow archaeological Jim Rock uncovered Khufu’s crystal dagger which first revealed Carter’s connection to the ancient Prince. Although his prime focus was on the pyramids in Mexico rather than Egypt.

Montana's son Rex as Metamorpho was a teammate of archaeologist Carter "Hawkman" Hall, as both were members of the Justice League of America. Prior to arriving on Earth-One, Hall originated on the planet Thanagar-One where as Katar Hol he was his world's premier policeman, sent to observe how humanity protected its citizens. Rex Mason lived the life on his world that Carter/Khufu Hall live on his own parallel planet, up until the time that Rex became Metamorpho and Hall became Hawkman. At that point, a new entity appeared with Rex's memories in Metamorpho, who's doppelgänger was a mutated Sandy Hawkins.

Indiana's contemporaries Hawkman and Hawkgirl were teammates of Sandy Hawkins, the lad who one day became his world's version of the elemental man, when he transformed into the Silicoid Creature. These three were members of the All-Star Squadron, while also working on cases involving the Justice Society of America of Earth-Two. In an alternate future timeline, Sandy was connected to the Halls when he formed a bond with Shiera, first seen decades earlier when he and Hawkgirl teamed up to save Sandman and Hawkman in early 1942.

The parentage of Sandy Hawkins has never been revealed, as he was an orphan before Wesley "Sandman" Dodds accepted him as his ward following the death of Sandy's aunt... and Wesley's girlfriend... Dian Belmont. It is possible that Sandy's father was Henry "Indiana" Jones Junior himself!
