Icerax

As a Matoran
Icerax was a very wise Matoran on Metru Nui, often studding with Nuju. When Nuju got his Toa Stone he came to him and asked if Icerax wanted it he said "No, its your destiny to become a Toa." Icerax was put into a Matoran Pod and saved by Turana. While on Turana Nui he studied everything he could. When the skill contest came he won, Matoran say he won because he knows every thing.

As a Toa
In Voya Nui he froze all of the Piraka, but they broke out and he and his team failed. While on Karda Nui he fought off most of the Makuta there and found out about the Codrex, and the Keystones. He told the Toa they should break it incase different Toa needed them, and so they did. They later left and after they found out Teridax ruled the MU he decided they should go to a pocket dimension. They were standing on a clif and he noticed Tidrax standing there he jumped on him, but Tidrax caught him and desolved him, killing him.

After Life and Legacy
While the Toa were in the Pocket Dimension Rena and Nero made an ice axe in honor of Icerax, they also made a patch of land covered with ice and named it after him. Stories about him were told about him to the Matoran describbing him as a brave, heroic, and courageous Toa who, in the end, sacrificed himself to protect everyone from Teridax.
