In the celestial paradise of Themyscira, two twins were born. One was the heralded daughter, Diana, known to the world as Wonder Woman. The other, a son, Orion, was neglected and overshadowed by his sister's glory.

Orion harbored no resentment towards Diana, but craved recognition. He sought solace in ancient texts and cosmic lore, eventually uncovering legends of a fearsome being known as Galactus.

The reclusive twin vanished from Themyscira, setting out on a journey across dimensions to seek Galactus. A newfound sense of purpose guided his path.

Galactus, the Devourer of Worlds, was intrigued by Orion's audacity and bravery. The cosmic entity saw potential in him and crafted him into a herald.

Orion's form altered to mirror the cosmos he now represented. He held the power to navigate galaxies, and warn civilizations of Galactus's impending arrival.

In his remote admiration for Diana, Orion was reminded of his duty to protect life. He used his newfound power to subtly save planets, earning him the label of 'traitor' amongst Galactus's other heralds.

Despite the whispers of betrayal, Orion continued his secret rebellion. His cosmic powers giving him the ability to seclude worlds from Galactus's relentless hunger.

Orion's actions eventually led to a confrontation with Galactus. An epic cosmic battle ensued, shaking the very fabric of the universe itself.

In the midst of the cosmic clash, Diana felt a disturbance and was drawn to the conflict. She bore witness to Orion's heroism, standing against the godlike Galactus.

Orion held his own against Galactus, but he was outmatched. Just as Galactus was about to unleash a lethal blow, Diana swooped in, deflecting the attack.

Aided by her long lost brother, Diana fought with unwavering determination. Together, the sibling duo matched Galactus's formidable strength.

The cosmic standoff fueled Orion's resolve. He merged his cosmic energy with Diana's divine might, creating a force capable of repelling Galactus.

Galactus retreated, realizing the combined force of the twins was a threat he couldn't underestimate. In defeat, he pronounced Orion free of his service.

Diana reveled in their victory and looked upon Orion in a new light. She marveled at his transformation from an overlooked sibling to a cosmic defender.

Orion, for the first time, felt truly seen by Diana. However, he knew his journey as a cosmic guardian was just beginning.

Orion bid Diana a heartfelt goodbye, now bearing the weight of his cosmic responsibilities. He promised to protect innocents across the universe, just as she did on Earth.

Diana watched as her brother disappeared into the cosmos. She vowed to his retreating figure that she would no longer let him be forgotten.

Back on Themyscira, Diana spoke of Orion's heroism. The Amazons, moved by his sacrifice, pledged to honor the once neglected twin.

The sun set on Themyscira, casting a golden hue over the paradise island. In the heart of the cosmos, Orion watched the same sunset, finding solace in the shared sight.

Orion continued his tireless journey across the cosmos, maintaining his silent vigil. He was no longer the neglected twin, but a guardian of galaxies, a cosmic beacon of hope.

Diana, on Earth, fought for justice and peace. She remembered Orion in her battles, drawing strength from his valiant stance against Galactus.

The siblings, worlds apart, carried their bond with them. Their shared courage and desire to protect life united them across the cosmos.

Orion's tale became a beacon for all neglected beings, proving that obscurity could be transformed into strength. He shone brightly in the cosmos, a testament to the power of resilience.

The tale of the neglected twin and the renowned Wonder Woman spread, serving as a reminder that all had the potential to be heroes, regardless of the shadows they might dwell in.

Orion and Diana's shared legacy lived on, inspiring generations. They stood as a testament to the strength of siblings, the power of resilience, and the unyielding spirit of heroes.
