First of all! Nemesis is kind of biotec weapon
created by Umbrella corp. and you probably know that. I asked myself who he really was,too, but then I started to slippin`.
I realize, that fact of who became, or who nemesis was in his past is absolutely something that we don`t have to take care of.
Nemesis was created to wipe all members of S.T.A.R.S. (in the game) and we all can see that. In the movie, we can see it, too, but they have presented him in so different designe & I think that they wanted to make some difference whit him in the movie and in the game, and don`t get that two thing twisted if you want to resolve the problem in your head, becouse movie came out after fiew yers from the game`s poped up and executive producer of the game planned to make a change.I played all parts of game till the RE Nemesis and I didn`t see anything about project Nemesis. The only people who know something about, who Nemesis really was, is CAPCOM tim members and that`s where we are going to stop are discussion.
P.S. If the fact of ``unknowning`` roots of Nemesis, drives
you crazy, just make your own story and enjoy in your own imagination.***
