Damaged Quadraxis

From Wikitroid, the Metroid wiki

After Samus defeats the first form of Quadraxis the four legs drop to the ground. The legs no longer serve any function other than providing tactical data to the Shielded Head Module via an antenna that can only be targeted by the Echo Visor. Once Quadraxis's Shielded Head Module is defeated, it is revealed that the four legs also hold Spider Ball tracks
