Operation: Argyranthemum more commonly called Project: Argyranthemum and occasionally called The Super Knight Project was a secret project within the upper echelons of the Imperial Knights organization within the Empire. The Operation was highly illegal by Galactic standards, but the project supporters justified it by believing that Rules and Laws would have to be broken to bring about a better Galaxy in the future.

Project: Argyranthemum subjected volunteers within the Imperial Knights to a series of operations consisting of skeletal grafting, chemical injections, and cybernetic implants such as the Ocular Enhancement Implant. Many of these operations were derived research from the Blue Sun Artificial Force User project captured by Norn Dukai The skeletal grafting made the subjects bone much harder, and more difficult to break. Steroid and Chemical injections increased muscle density and strength. And the implants enhanced sight and hearing.
