Portal

Portals are dimensional anomalies found on Aether in Metroid Prime 2: Echoes. Due to the dimensional instability caused by the impact of a Leviathan, Light and Dark Aether often overlap in places. This can cause areas where matter can travel from one to the other. These portals can lead both ways or may be one-way path. Regardless, in their natural state, the portals are too unstable for anything to safely pass through. They can be stabilized by dark or light energy, depending on the type of portal. Energizing them in this way temporarily allows any matter to safely pass through. The Luminoth created large devices around some of these portals, which allow one to energize the portal by interacting with the controls. Samus requires the Light Beam and the Dark Beam to travel freely through these portals. A strange portal can also be found underneath the Great Temple in the Hall of Honored Dead. This dark portal is constantly energized, and scans indicate that it is unable to be traveled. The equivelent portal on Dark Aether is covered in Phazon. When Samus escapes the collapsing Dark Aether, she uses this portal as both sides are now free of obstructions.
