Final Fantasy X-2/Machina Maw

Rikku's special dressphere. To activate this dressphere you must traverse the entire garment grid you're using during a battle and then the command will come up the next time you do a dressphere change. This means that you control only Rikku, but you can control the Left and Right wings to attack as well - it's just like fighting with three people.

Aquiring the Sphere
You can find it at the Oasis in Bikanel Desert in Chapter 2.
