CONQUESTION - The Last Guardian -
About
One day, a Conquestionian (the father) descends to Earth.
"I have come to dominate the development of your civilization," he explains.
However, that was a lie.
His true purpose was to conduct a survey of Earth, investigating military power and human capabilities to gather intelligence for a future Conquestionian invasion.
He was the vanguard of the invasion force.
But something changed within the father. During his long years living on Earth, he came to know humanity, started a family, and learned of love. A sense of morality he never possessed began to sprout, and now he wishes to protect humanity.
Earth Government The government is aware of his existence.
However, they do not view him as an enemy. Instead, they cooperate with him on space technology, disaster relief, and planetary defense.
Description Conquestionians are hyper-evolved lifeforms indistinguishable from humans, hailing from a planet far from Earth known as the Conquestion Empire.
Characteristics Their appearance is entirely human.
Lifespan Average lifespan is approximately 5,000 years. Long-lived individuals reach 7,000 to 8,000 years. Legendary classes live over 10,000 years.
Physical Abilities Capable of free flight. Can operate in the vacuum of space. Bodies harder than steel. Earth's weaponry is almost entirely ineffective. Miraculous regenerative abilities. Resistance to toxins, radiation, and extreme temperatures.
Scientific Prowess A super-civilization far exceeding Earth's, particularly advanced in spacecraft and transport technology.
Weaknesses Extremely sensitive ears; vulnerable to powerful ultrasound or loud noises. Can be harmed by ultra-high-density materials that do not exist on Earth. If infected with a Conquestion-specific artificial virus, they are weakened to human levels.
Evolution by Age As Conquestionians age, their muscle strength, defense, regeneration, combat ability, and judgment continue to grow. They do not weaken due to aging. Combat experience also significantly impacts their actual power.
Values Pure meritocracy. Strength is everything. The weak have no value. Only the strong are respected.
