Whom Do You Consider The Greatest And Most Memorable Characters In All Of Cinema ?

Kong! Kong! Kong!

Howard Rourke in the movie The Fountainhead.
There are many better than the one I'm going to name like Kikuchiyo from The Seven Samurai(1954) or Jaguar Paw from Apocalypto(2008), but I'm going to go with Jordan Belfort from The Wolf of the Wall Street(2013) only because I've been re-watching this at a time of personal financial crisis. Might edit this post later when all is well haha.
