Vegnagun

An oversized, dangerous and extra-powerful machina in Final Fantasy X-2. It is hidden underground Bevelle, and is said to be able to destroy Sin. It's also the main goal for Shuyin to obtain, for with it, he can get rid of his image of what Spira truly is: a corrupted world of violence. Vegnagun has a mind of its own, can be activated by a magical piano attached to it with a special key melody, and is separated in parts such as Legs, Head and the such.
