Super Ground Quake
Super Ground Quake is the final Staff Upgrade in Star Fox Adventures, obtainable from the Magic Cave of Walled City. It is a more powerful variant of the original Ground Quake, and supersedes it in the C-Stick Inventory when obtained (although it is still recorded in General Pepper's report).
The Super Ground Quake is essential for defeating the RedEyes, because an ordinary Ground Quake attack is not powerful enough to defeat them. When Fox uses the Super Ground Quake, it creates a large orange shockwave on the ground. Fox also charges the Super Ground Quake in midair a bit longer before unleashing the attack. Performing the move depletes almost half of the last Staff Energy Meter upgrade, which is more than what is used by the Ground Quake.
Even though it is more powerful, the Super Ground Quake is about as effective at defeating Kalda Choms as the Ground Quake.
