If you mean warrior, she has never been possessed by one. Only by Tsubaki, a priestess in episodes 60-62. And by the baby under Naraku's orders in episodes 125 & 126, though he never actually possessed Kagome, only attempted to. And lastly in the first movie by Menomaru. You may have gotten the idea that she was possessed by a warrior from the first movie's trailer in which Kagome is seen fighting Inuyasha with a sword, but this does not actually happen in the movie.
