Reptilicus Hunter

From Wikitroid, the Metroid wiki

Reptilicus Hunters are creatures from Metroid Prime 3: Corruption.

They are a specialized variant of the Reptilicus warriors. They are Reptilicus that have been mutated by phazon, giving them powers that a normal Reptilicus doesn't have. They have all the abilities of a Reptilicus plus the ability to turn invisible. They are found on Bryyo. They also have the ability to warp short distances.

Until you get the ice missiles and the X-ray visor, the easiest way to deal with them is to go into Hyper Mode. However once the X-ray visor is collected you can see them when they are invisible, and the ice missile will slow them down or freeze them leaving them vulnerable to attack.
