A YJA Moment - The First Infinity Guantlet

 Long before Thanos forged his begun his crusade for the Infinity Stones, there was another powerful force that attempted to unite the stones and elevate themselves to godhood.  A force that came from an outer rim world known only as Triterra.

Many great civilizations rose and fell upon Triterra - some possessing great technology, others skilled in the arcane arts.  They uplifted animals into humanoid forms and attracted near-by aliens to immigrate.  By the time the Enshrouded One had come to power, the empire is in decline, which much of the population living in small settlements.

The Enshrouded One, the undead warlord known only to a few as Mumm-Ra, had been resurrected by the mysterious Ancient Spirits of Evil in order to complete the profane task of seeking out the Infinity Stones.  Forging the Gauntlet of Plun-darr, Mumm-Ra sent his elite force, the ThunderCats into the cosmos to collect them.

Leo, the leader of the ThunderCats realized that with the Stones and the Gauntlet the Enshrouded One would become a virtual god and no one would be able to stop him.  He set in motion a plan to collect a group of heroes to fight Mumm-Ra in secret, while the ThunderCats publicly sought out the stone.

In his travels, Leo recruited C.C. Batson, the original Captain Marvel; Emiya Shirou, the Crimson Archer;  Interstellar lawman Thad Bak, The Space Ghost; Noran Radd, the Silver Surfer; and GCPD officer Jim Corrigan, host to The Spectre.  

Leo and his secret allies managed to locate the Stones, taking them back to Triterra and using them to defeat the Enshrouded One and sealing him within his Black Pyramid fortress.  

Victorious, the team decided to protect the stones from anyone who tried to collect them.  Each taking a Stone, the heroes parted and spread out throughout Known Space.  Leo took possession of the Space Stone, mounting into the hilt of his weapon, turning it into what would be later known as the Sword of Omens.
