Dream Fencing

Dream Fencing is an unlockable Dream Event in Mario & Sonic at the Olympic Games. It is very similar to normal Fencing, except this version more closely resembles one-on-one fighting games, as the characters now have health bars and the goal is to deplete the opponents health completely and defeat them, rather than simply scoring a certain number of hits. Also, the competitors can now use "special moves" which are unique for each character. Four players duke it out in a tourney tree-style competition aiming for the top three spots. This is just like Dream Table Tennis, regular Table Tennis, and regular Fencing.

When a player uses a special move, a character's icon of the top part of their face flashes across the screen and they unleash an attack that can only be blocked if the opponent strikes the player while he or she is charging the attack. It's possible to knock the player out of the arena which will make them take some damage. If an opponent if forced to back up as far as they can go, the other player can use a special move and blast them out of the stage. If the knocked off player still has enough health left, the fight will continue with both players set to their starting positions.

DS version
Much like regular fencing, in the DS version, the player slides the stylus at the opponent to hit them. Sliding up will block a strike from the opponent. However, if the opponent blocks the player's strike, the player must slide the stylus back and forth across the screen quickly to recover. To use a special move, the stylus must be slid down. If there are no special moves charged up, the special move will not work. In order to move, the player uses the D-pad.
