Dark Force, the main opponent of most Phantasy Stars, is an embodiment of hatred and evil that threatens the Algol system from millenium to millenium, and has had various forms to draw from since his first appearance. He is the Profound Darkness' most powerful servant. Many times he was defeated, many times he has returned. It seems that the battle against Darkness in Algol shall never end, and Dark Force will always return, calling the world to darkness... as he did several times.
