For those of you who have not heard, Highlander is a movie/tv franchise where these ancient people battle one another throughout time and the rule is; there can only be one. That means these men must battle each other and the only way to kill one another is by chopping off the head and to do that, you gain their power.(they are not really good movies, but it is a cool idea). So what I propose would make an awesome idea is to have a dark jedi who has learned this ability to absorb other's force powers and abilities unto himself and grown stronger. He/she goes throughout the galaxy killing force users becoming more powerful as he does. I think that if there was this hidden prophecy and there could be this jedi who is on the grayside who learns of it and falls to darkness as he tries to kill gain this power. He goes off on his own, telling everyone that he is going into exile to meditate and learns how to do it. So now we have this dark jedi roaming the galaxing battling and beheading non-jedi force users(so as not to draw attention to himself by the jedi) and gaining their powers so that he can become the strongest jedi in the galaxy. As he goes along he gains more and more power, which we know that power corrupts and starts taking out lesser known jedi. This could escalate and eventually we have him battle like 5 jedi at the same time and kill them all and I'm not sure of the climax, but he ends up getting beheaded himself I think, but then the jedi who kills him becomes corruptible. Tell me what you all think!
