Doc Vega was not born with a human name. In the Alpha Centauri Empire, individuals are identified by structured codes rather than personal names. His native identifier is V15-3491, a designation that reflects the orderly, highly civilized culture from which he came.

​

Before arriving on Earth, V15-3491 served aboard an Alpha Centaurian exploration vessel assigned to monitor Earth and its inhabitants. The mission was not one of conquest or infiltration. The Alpha Centaurians were observing a young and volatile world from a distance, attempting to better understand humanity, Earth’s biological diversity, and the planet’s place within a wider galactic context.

​

That mission ended in disaster.

​

In 2009, the Alpha Centaurian vessel was attacked by ships created by the Galactic Expatriates, a dangerous villain group made up of renegade aliens with ambitions far beyond piracy. Their goal was to commandeer the Alpha Centaurian ship, use it as an orbital base above Earth, and eventually enslave Terrans for their own demagogic purposes.

​

The Alpha Centaurians resisted, but the attack crippled the vessel. Instead of becoming a platform for the Galactic Expatriates, the ship crashed into the Rio Grande River. The crash killed nearly the entire crew. Only a dozen or so survived, most of them badly injured. The Galactic Expatriates escaped unharmed and began scavenging the wreckage for weapons, technology, and anything they could exploit.

​

GUARD’s Astroguardians arrived before the Expatriates could fully loot the ship. A battle followed, and the Astroguardians drove the attackers away. Afterward, they discovered the surviving Alpha Centaurians in the wreckage and tried to save them.

​

That rescue attempt became one of GUARD’s most painful early lessons in alien medicine.

​

GUARD doctors did everything they could, but they did not understand Alpha Centaurian physiology or the biological needs of the other alien lifeforms aboard the vessel. Despite their best efforts, most of the survivors died from injuries that Earth medicine could not properly treat.

​

V15-3491 was severely injured, but he survived long enough to witness the effort. He saw the frustration, urgency, and sincerity of the GUARD medical personnel trying to save his crewmates. They failed, but not because they lacked compassion. They failed because Earth lacked the knowledge.

​

That distinction mattered to him.

​

When he recovered enough to communicate, V15-3491 explained the Alpha Centauri Empire’s peaceful intentions and practices. He shared information about his civilization, the races known to the Empire, and the renegade alien groups that formed much of the Galactic Expatriates. His testimony gave GUARD some of its most valuable early intelligence on extraterrestrial political and biological realities.

​

He also delivered a warning.

​

Before the crash, the ship had sent a “ship compromised” message back to the Alpha Centauri Empire. The message was intended to prevent rescue attempts from falling into enemy hands. It did not explain the full situation. The vessel’s logs had been jettisoned toward the Empire to provide evidence of what had actually happened, but those records would take approximately ten years to arrive.

​

Until then, Earth could be misunderstood.

​

From the Empire’s perspective, Earth might be classified as a hostile planet until the logs proved otherwise. V15-3491 understood the danger of that misunderstanding. He also understood that Earth was not ready for alien medicine, alien diplomacy, or alien biological emergencies.

​

Rather than leave, retreat, or simply wait for the Empire, he chose to help.

​

V15-3491 volunteered his knowledge and healing abilities to GUARD. Because of his extensive understanding of alien physiology and his rare biological healing capabilities, GUARD leadership recognized that he was too important to assign only to field heroics. Although he could logically have joined ASTROGUARD or the Astroguardians, the Director of GUARD kept him closer to the Executive and Medical structure in case the Alpha Centaurians returned or formal contact became necessary.

​

GUARD Medical then created a new specialized subdivision: ACARE — Alien Care.

​

V15-3491 became its founding director.

​

Under the human-friendly name Doc Vega, he helped transform GUARD’s alien medical capacity from emergency improvisation into structured xenomedical readiness. ACARE exists because of what happened after the Rio Grande crash. It exists because good intentions were not enough to save his crew. It exists so that the next alien patient, refugee, survivor, prisoner, diplomat, or stranded traveler is not treated as an unknown object, but as a living being with rights, biology, culture, and dignity.

​

Doc Vega also adopted the informal codename Ack-Ack, a choice that surprised many GUARD personnel. After seeing an Earth comedy involving Martian invaders, he found the sound funny and selected it for himself. The name stuck, partly because it showed that the disciplined Alpha Centaurian healer was willing to embrace Earth culture on his own terms.

​

Today, Doc Vega stands as one of GUARD Medical’s most important figures. He is a healer, survivor, diplomat, scientist, and living bridge between Earth and the Alpha Centauri Empire. His mission is simple but enormous:

make sure GUARD never again loses alien lives because it did not know how to save them.
