Mereagros, who rules over the Altria system as its king, possesses an impressive charisma that allows him to wield absolute power over the forces of the Iron Tribe. He believes he has every right to do anything he wants, simply because he is in charge. After gaining control of Age through cunning political tactics, Mereagros leads his troops into battle against the Bronze and Silver tribes with reckless abandon, relying solely on Age for victory. Following this triumph, he attributes it entirely to his own strategic prowess.
Mereagros's inflated ego often causes him to make impulsive decisions that put both himself and others in danger. For instance, he orders the destruction of an entire planet just to eliminate an enemy fleet, despite knowing that Age will be caught up in the explosion. His disregard for his troops' lives eventually leads to a confrontation with his sister Dhianeila, who removes him from command and replaces him with Nilval.
