In place of the human race that degenerated physically, these artificial humans became the new normal of the Red World. Their real nature are clones created from the genes of various superior humans (well known geniuses and heroes) who existed in the past.
While they are artificial humans who resemble those people, they also have their memories, so they are practically the same person as the original. In addition, their already excellent genes have been further improved, allowing them to break through the limits of humanity.
Although their clothes and weapons conform to the depictions in myth and legend, these reproductions are powerful weapons jam packed with every technology possible, to reproduce and exaggerate their roles as heroes.
