Gate Guardians (Earth-4001)

"Although this is not a sea creature, I am the one best suited to comment on it. Gate Guardians are vicious little cowards, hiding behind a false front so they can attack at will. It is bad enough the Visorak came to Metru Nui without bringing these foul creatures with them."

- Rahaga Gaaki

A Gate Guardian is a large Rahi that projected an image of a smaller vision of itself while keeping its real form invisible. They were an ally of the Visorak. They walked on two legs and had two heads, one on each side of their body. Enemies often exhausted themselves trying to bring down the small Guardian they thought they were looking at, never knowing their true opponent was hidden from them.
