Telethia, the Endbringer

Telethia, the Endbringer is a Tyrant in Xenoblade Chronicles X. It is one of the only two Telethia encountered in the game and is revered as a local deity by the inhabitants of Mira. Two version of the enemy exist, the first on appears at level 99 at the Divine Roost in Noctilum during the "The Nopon Heir" mission and must only loose 5% of its HP to complete the mission's objective. The other version is found at the same level and at the same location but is not exclusive to any mission and has different drops and stats. This version must be defeated during one route of the "A Fateful Choice" mission. Defeating it as part of the mission will not count towards segment recon.

In Game Description
"This giant indigen circles the skies of Noctilum, making its home in the giant trees there. It's rather unpredictable, and has even been known to assist BLADEs."

Trivia

 * Telethia, the Endbringer is the strongest enemy in Xenoblade Chronicles X.
 * It doesn't activelly try to harm Humans but it is hostile toward other life forms like the Orpheans.
 * This may be due to the fact that Humans are just remotely controlled androids in this game and the Telethia are known to hunt and destroy organic life exclusively unless machines are getting in their way or conflict with their goals.
