These are the Attack On Titan Vanquish Arcs that have happened so far in our lore.

Cloak Arc Edit

A mysterious organization nicknamed, "cloaks" attack important figures in the military and government of Humanity. They claim their goal is to save Humanity from itself. They end up kidnapping the SLC, gamingfeva and are forced to retreat after a rescue attempt is made ending the cloak arc. The leader of the cloaks, Omega, turns into a titan clad in armor, but, he's ultimately defeated by mrchar, who also has the power to turn into a titan.
