Battle Spot allows players to participate in randomly selected battles, not unlike Global Battle Union's Random Matchup. The battles can be done in Free or Rating mode.
Wonder Trade lets players trade Pokémon with each other but the player doesn't know what the other player is going to give them in return. Therefore it can be considered to be a 'blind swap' in that the players do not know what they are getting back.

Global Trade Station
The Global Trade Station is not a new feature but it is unique in Pokémon X and Y due to the fact that it can be accessed anywhere rather than just being able to be accessed in Pokémon Centers like in Generation V. What is new to the GTS is that players can now ask for Pokémon which have not been registered in their own Pokédex.
O-Powers can give power-ups, increase/decrease chances of things happening, and can be shared with other players. They are similar to Entralink Pass Powers but O-Powers can also be shared by a nearby player as well as the original user.
