Battle Arena
Battle Arena is an online mode that allows people to battle with each other in an arena. In the Battle Arena, a room can be created for friends to join. When joined, players must first choose a character before being displayed on the arena. If one wants to switch characters, they must leave the arena before doing so, although this places them to the end of the line. The rules in the Battle Arena are pre-set by the creator of the room. Once the creator leaves the room, the room closes and everyone is automatically kicked out.
In the Battle Arena, players are represented by tokens. Tokens can be placed in the ring to start the fight, the waiting area to wait in line, or the spectator stands to spectate the match.
Battle Arenas created by friends are visible on their friend lists. People who aren't registered as friends can still join other player's Battle Arenas, however they would need to search for the Arena ID. Furthermore, Battle Arenas can be set with a password so that only those who have the password can enter.
This is the only online mode where spirits can be used.
