So I wanted to implement an antagonist character into a story of mine. His thing is that he's a withered scientist that built himself a power armor to sustain his life. He was a major player during a war and when he was mortally wounded, people opened up his armor and found a mummified corpse, leading people to believe he died. In reality he transferred his mind into a computer long before and he's spent several decades slowly rebuilding himself. This character sounds a lot like Voldemort or Sauron and I'm afraid people will think this is cliche. What do you think?
