this is a plain arena with no obstacles. You can have 2-on-2 fights here.

Concept of the 2-on-2 Battle Arena:
When you come in here and you see someone else here that you want to partner up with, ask them to be your partner for that fight. If they say yes, then you can be partners. if they say no, then find another partner. When there is another set of partners that want to challenge you (or you want to challenge them) then the battle will start. You and your partner will help each other defeat the other team. You CANNOT attack your partner.

You can also have 2-on-1 fights here, but the same rules apply.
