Sylvester McCoy became our seventh Doctor bringing another change of pace.  He started out as quite comedic with a ready quip, even in difficult situations.  But his personality gradually became darker and almost secretive. We have met Sylvester on several occassions and he is always really sweet and funny. He was our Doctor from September 87 to December 89 with 42 appearances over 3 seasons. He also appeared at the beginning of the 1996 film.
