Real World / Sword Art Online / ALfheim Online / Gun Gale OnlineEditEdit

During the past of «ALfheim Online» and «Gun Gale Online», Tartarus's avatar was the same in both games having a sliver and black armor with black wings, a red sword with a red gem on it and his face with a lions mouth and a red gem on the center of his forhead.

In «Sword Art Online», his appearance changes completely calling it the "Transfiguration Ara" in witch his sliver and black armor body was covered in a golden armor suit with green gems on his chest and a green gem replacing his red gem on the center of his forhead. His wings were changed into a long red and blue cape and his eyes were replaced with six red eyes.


Tartarus's is a cold hearted leader believing that one(s) with power can only survive in the real world and that only one can lead everyone in online to balance judgement and order. He pretendes to care about his follow Nexus Яeverse members and tricking or controling them into doing full on damage to there opponents showing no mercy or pity.


Born on September 17, 7007,  Tartarus Abyss/Chrome Changer was a scientist at Z-Gala Industries, humanity's accelerated to evolution leading to a better and peaceful society.
