T-elos is the antagonist in Xenosaga III, one of Monolith Soft's games before becoming one of Nintendo's subsidiaries. Due to a partnership between Nintendo and Bandai Namco, she appears in some of Monolith Softs more recent work even after the buyout.
In Xenoblade Chronicles 2, T-elos appears as a Rare Blade. She can grant tremendous power to her Drivers, Rex, Nia, Zeke, or Mòrag, and their allies. T-elos uses the Dark element, wields a Greataxe, and acts as an Attacker in battle.
