Supermen of the Old West: The Super-Sire & the Super-Chief

Flying Stag was a young member of the Wolf Clan, who aspired to be the supreme chief of the Iroquois nation. However, some of his rivals conspired against him, and trapped him in a pit. Therein, Stag found a meteorite that imbued him with superhuman abilities and made him think he had seen a vision of Manitou, whom he served and whom he believed directed him on a mission to protect their people while keeping his identity secret. 

As Saganowhana, which in English is translated as Super-Chief, Stag was a fearless fighter while concealing his true identity in a mask. Eventually, Super-Chief was thrusted from his old west era into the 20th century of his native Earth-Two during the Crisis on Infinite Earths. What became of him after assisting several other time displaced champions following this tale is unknown. His old west story mirrored that of an ancient Kryptonian’s a universe away.

Var-El was the great-grandfather of Earth-One's Superman, and a prominent scientist of his native planet Krypton-One. When he discovered the means of traversing vast tracks of interstellar space through a dimension of universal energy storage. Ending up stranded in the old west of the 1800's on Earth-One, Var-El lived his life assimilating to this new civilization while adapting to his new superhuman powers under Earth’s yellow sun and lighter gravity

Eventually, he was discovered by the Orgon, an adversarial alien race intent on assimilating knowledge from other species. Escaping them, Var-El met up with a time travelling Professor Hyatt, who had himself journeyed to Var-El's era alongside the Atom and Superman. After this adventure, Hyatt secretly smuggled Var-El to the 20th century, although the elder Kryptonian once more had to face a renegade yellow-skinned Orgon, whom he sacrificed his life to vanquish it.

In an alternate timeline, a young Clark Kent encountered remnants of Kryptonian technology within the Kawatche Caves, guarded by a local Native American tribe residing outside of Smallville's town borders. A mystery man from the stars mentioned a future of Naman who would protect their world, with a powerful extraterrestrial rock left behind.

A Kryptonian individual spoke through the technology, which mirrors how Flying Stag gained his meteor rock with powers and a mission. And in fact, it was later revealed that a Kryptonian Crystal in the 20th century which absorbed a portion of Kal-L’s powers and persona had traveled backward through time into the era where Flying Stag found it, making him in effect a human-Kryptonian hybrid and thus relation of Superman himself!

This makes him his world’s version of Var-El, with indications that Manitou and the meteor were Kryptonian in origin.
