Erutan

Erutan is the guardian of the Earth and the mentor of the Guardian Gem Rangers.

Biography
Erutan's origins are unknown, but he lived on a secret island in the Atlantic Ocean. Upon being awoken in the modern day, he was horrified by the extent of pollution. Noticing a teenager freeing a dolphin from a net, he retrieved the Guardian Gems and sent them out to find others like him and grant them enough power to improve the situation. The first chose the dolphin rescuer, Walter, who began fighting as a Ranger. He noted the potential of another teenager, Ralph Knight, and when he managed to get his gem, told him to help Walter by becoming the White Ranger. Ralph only stayed long enough to solve the immediate problem, and Erutan had to drag him away from a conversation with Minamata to deal with a fire.

Afterwards, the two headed to the base, where Erutan tried to explain how fate had chosen Ralph for this job. Ralph accepted it, said he worked alone, and left before anyone could stop him. Erutan brought him back to make him talk in private. He explained that he and Walter had more in common than Ralph thought, and insisted despite Ralph's arguments that he'd be a good member of the team.

Personality
Erutan is typically nonconfrontational, trying to talk people into what he wants rather than force them.

Talents and Abilities
Erutan can apparently project himself anywhere, including into the minds of his Rangers.
