Near the point at which you start is something resembling a twig embedded into the ground. While standing on top of this twig, you are completely immune to Metroid Prime's shockwave, it's only (common) attack. The only things that can hurt you are the short range lunge attack and spawned Metroids, which fall easily anyway. Curiously, while standing here, Metroid Prime will not change emission spectra without laying a pool of Phazon, which helps the fight along considerably.
