"Nuva" There is little left of the mind this former Toa once had. He was subjected to experiments which grotesquely increased his physical strenght and size - from which he mockingly got named "Nuva". This beast-like being now roams the lands, uncontrollable and relentless.
Iselia Having mostly known the icy caverns of Iconox, the reformation of Spherus Magna gave the unique opportunity to restart one's life - one that Iselia swiftly took. She would eventually settle in a dominantly Matoran village which overlooked the gigantic remains of the robot that came from the sky.
Lotuva Leaving the sands of the coast behind him, Lotuva met with the other chosen Matoran at the dune's summit. Here, he and the others would embrace their destiny and become the new Toa. Thanks to @bobthedoctor27 for sending me the red Pakari!
Tilira The past laid behind her but the unforgiving claws of guilt yet bind her. Tilira was once a proud member of a Toa-team of six, who were all decevied by a terrible trap. She was the only one to return from these shadows - and ever since that day never spoke a word about her former brothers and sisters. It seems that the truth of these events lie sealed within her mind.
Bima Av-Matoran captain of the guard. Name in reference to ToWFF member Bioniclemaster724.
Vokayu Unlike the rest of the rookie Toa team, Vokayu did not participate in the choosing trials they faced as Matoran, as she was specifically selected as a successor by one of the former Toa. Unfortunately, she thus feels like an outsider, lacking the bond of familiarty the other Toa have formed during their challenges.
Piolok The long years as a Toa of Air have left their mark on Piolok. While the Matoran of his kind are energetic and outgoing, the Turaga mostly keeps to himself and his laboratory in the great swamp.
