The Great Commander is a Boss opponent in Star Fox for the SNES.
The Great Commander is a sky-blue and white striped ship. It is able to shoot plasma and has several laser turrets. It will later transform into a more humanoid form and later a more "beastial" form.
To start the battle, the Great Commander fires multiple lasers at you whilst it appears on-screen. It will then begin a form of "jousting" - constantly flying by you and attempting to shoot. The aim is to shoot all the turrets on top.
