An Extremely large and powerful machine
in the game Final Fantasy X-2. Vegnagun is considered to be Bevelle's most powerful "Machina". The machine was designed 1,000 years before the events of
Final Fantasy X-2. It was thought to be able to destroy Sin. Vegnagun has a mind of its own and is considered extremely dangerous which is why it was sealed beneath Bevelle. In the game Shuyin sought to control this great weapon.
Vegnagun is composed of a torso, legs, tail,wings, and head. It's entire body slighty resembles that of a moth's, only that it's head is
different in shape and has horns on it and it has a
long tail at the end of it's body. Once Vegnagun begins to fire it's primary weapon it's lower jaw drops and a long barrel comes forth from within it's torso, looking like
the barrel of a giant gun, thus where it gets it's name, Vegnagun.
