As the legend goes, Ulysses was a caveman who witnessed a meteorite fall from the sky. Going to investigate it, he met an alien creature guarding a huge gemstone. Attacking the gem, Ulysses caused it to shatter into many pieces when he hit it with his spear. One of the shards embedded itself in his sternum, merging Ulysses with the Bloodstone itself.

The stone changed Ulysses, granting him immense power. Now Ulysses was immortal with many other abilities including superhuman speed, agility, strength, stamina, senses, and psychic abilities -- not to mention an immunity to vampires. Ulysses took his new skillset and hunted monsters over the centuries. Eventually, the Bloodstone was removed from his sternum and all of his years caught up to him, causing him to die.

However, the Bloodstone did not remain in one piece long after Ulysses's death, it shattered into several shards. The villains believe that the skeleton can help them track down the pieces to reassemble the Bloodstone and bring back its immense power for the one who wields it.

Luckily, as the group of bad guys chat about their master plan, another thief is eavesdropping on their conversation. Diamondback, a villain with a crush on Captain America, is discovered and attacked by the gang. They lock her in the crate with part of Ulysses's skeleton and toss her in a dark pit, thinking that is the end of their problems.

However, Diamondback had a communicator which allows her to contact Captain America. The hero makes his way through skeletons and ancient booby traps to find Diamondback locked in the crate. She quickly tells him the whole story as they go to Avengers Island. To help find the Bloodstone shards, Ulysses's skull is equipped with a compass to point the way.

The duo first travels to the deep jungle of South America. Traipsing through the dense foliage, Captain America and Diamondback are taken prisoner by an anachronistic group of Incas. The pair are drugged and taken back to a temple to be human sacrifices on the order of the shaman who wears a mask with a Bloodstone shard in it. Captain America is strapped to a wheel of death and sees that the villains he is after are also prisoners of the Incas. The Incas are defeated when Captain America and the villains work together, but Zemo manages to get the Bloodstone piece away before Captain America can stop him.

The next location is in a plane wreck at the bottom of the ocean where Captain America must battle giant sharks as well as the villains. Although the bad guys get the shard, Diamondback tussles on the surface with Zemo and manages to steal two pieces that he already had. In an ancient Egyptian pyramid, Cap and Diamondback move through snake-filled pits to find the next piece. Diamondback is grabbed by a mummy who also seeks the Bloodstone to resurrect himself. He agrees to keep the villains off of their trail if they promise to bring him the restored Bloodstone.

Even Captain America's villain Crossbones joins the hunt for the Bloodstone, competing against Zemo. Still, Zemo is able to combine the shards and make the Bloodstone whole again. Hoping to restore his father, Zemo instead brings forth an interdimensional being that they all must work to remove the Bloodstone from.

Recently, the Bloodstone has made a reappearance in the Marvel Universe in Deadpool. Ulysses's daughter, Elsa, has the stone embedded in her hand but it is killing her. When she tells Deadpool of her fatal issue, his solution is simple. He pops the Bloodstone out and pushes it into his own chest to fight a monster queen. Though Captain America found the Bloodstone on his Indiana Jones adventure, the relic may change the future of Deadpool and his current monster kingdom.
