It becomes a queen
When a pawn reaches the other side of the board it can be exchanged for any other piece except a king. The choice is not limited to pieces that have been captured. This means that a person can get another queen for every pawn that reaches the other side and have several queens at the same time.
Reaching the end of the chess-board is only significant to the pawn who then can be promoted to any chess piece other than the King .
Nothing happens. Only pawns accomplish anything by reaching the other side of the board.
