This is Scalus, Toa of Iron. He is a simple Inika build, and I never had much of a backstory for him. All I had was that he was on the same team as Umbrus.
He was always easily angered as a Matoran. He was not going to be chosen by the soon-to-be Turaga, but the Matoran they, chose, Ferrak, did not want to have the job, so he threw the Toa stone he was given down a mine shaft.
Scalus was at the bottom. He found the stone, with a message saying "journey to the temple of heroes past to achieve your destiny," and thought it was intended for him. That's all I ever created for him.
Underneath the Av-Matoran Body. I improved a little over Umbrus by filling in the center cavity.
