Here is Ultrio, the warrior of vengeance.
Bonus: From now on I would like to provide the most influential song I listened to while building each of my mocs! This moc was mostly inspired by this song:
Ultrio lives in a universe were the Toa are corrupted, and have taken complete control over Mata Nui Island
Him and his friend were making an ultimate weapon to fight against the fierce Toa, but they had been found out, and the Toa attacked their lab.
Trying to protect his brothers, he equips The Mass Armor, the project they had been working on. Having it on increased his strength by tenfold and morphed his body. He tried to reach his friend in time, but it was too late. The Toa had killed his orange companion, and now wears his mask on his chest to honor him.
From that day he promised to avenge the deaths of so many matoran.
Ultrio prefers hand-to-hand combat, but when it's needed he will draw his sword and fight with full force.
Let me know what you think ^^ He's still my first ever MOC so I apologize for any newb building tactics.
