T-elos is a battle android from the Xenosaga series of games. She was created by Roth Mantel, an alias of Kevin Winnicot, a former Vector scientist. She is quite similar to KOS-MOS, as they were designed by the same man, and is also the opposite in some features. T-elos has tasked herself with destroying KOS-MOS. She has similar abilities to KOS-MOS, as she can create weapons, although T-elos tends to rely on a blade on her left forearm, as well as a Phase Transfer Cannon that is inside her chest.
T-elos only appears in Xenosaga Episode III: Also sprach Zarathustra, although her name is mentioned several times in the other game. She also appears in both Super Robot Taisen OG Saga: Endless Frontier and Mugen no Frontier: Super Robot Taisen OG Saga EXCEED. Her appearance in Project X Zone has her paired up with KOS-MOS.
