Telethia

Telethia are an enemy species in Xenoblade Chronicles and Xenoblade Chronicles X.

Xenoblade Chronicles
Pure-blooded High Entia turn into Telethia if they come in contact with high concentrations of ether.

Story
The first Telethia seen is the Sani Telethia where it saves Shulk and the party from Metal Face, before meeting up with its handler, Alvis.

Xenoblade Chronicles X
There is one Telethia that resides at the top of the Divine Roost in the northern heights of Noctilum:. It lives inside the gargantuan plant in the middle and makes a large circle around that area regularly.

During the events of, three Tainted Sphinxes are about to attack Elma, Lao, and their team. Suddenly, the Telethia comes to save them by snatching one, dropping it from the sky, and then smashing it into the ground. It then takes out the other two, destroying them without mercy before regarding Elma and her team. Eventually, it flies back into the sky, leaving the team to wonder if it was helping them or just toying with them.

The Telethia is also known for their guardian etherscales, which are part of an ancient Nopon remedy that Cross and L are tasked to get during the mission The Nopon Heir. While they only manage to damage it slightly, it decides to give them one without destroying them, perhaps because L claims it can read the hearts of those it sees and judge their worth.

Description
''Said to be Mira's guardian and culler of unclean lifeforms, the Telethia is also known as the "Ruler of Fates." It is rumored to have mind-reading abilities that make it virtually invincible--a theory strengthened by the fact that is has never been defeated in combat. As if that wasn't enough, the creature's vast wings also have the ability to amplify and manipulate ether in the surrounding atmosphere.''
