Aidan Thanatos

(also known as Theta Tau Omega Sigma or ΘΤΩΣ) Aidan Thanatos is an Omega-Class Entity residing in a plane of existence known as Space-Time Six, at the identity coordinates Theta Tau Omega Sigma, and is a primary character in Legend of the Ultimate Sword. He is not a native of ST6, but is/was a Zet named Thanatos who ascended to Omega-Class along with his five siblings as a result of repairing a kaleidoscopic reality fracture.

Powers and Personality
Aidan Thanatos is the essence of the noble warrior, the self-sacrificial quality of a great leader, and the face of death in battle. His Avatars are one and all absolute masters of hand-to-hand combat, bladed weapons, and practically any technological weapon they lay hands on.

Aidan Thanatos has a unique continuity-quirk, in that any Avatar he possesses will at some point be retconned into having been Thanatos the Zet the whole time. On top of their already impressive abilities, Avatars retconned in this way will gain all the strength and powers associated with the original Thanatos, making them even more formidable in battle. Because of these retcons, no Avatar of Aidan Thanatos ever suffers from Code Samson.
