Yiolu

Yiolu is a Toa of Fire and Great Supervisor of the City of Junctus Prime. He was Head Doctor of the Medical Team sent to Karda Nui and became team leader of the Toa Junctus after Destros' resignation.

Creation and Mata Nui
Like all Matorans, Yiolu was born from Protodermis a long time ago, created by the Great Beings. Afterward, he was sent to assist in the construction of Mata Nui's Robot, and when it was over, he was sent, like the majority of the Matorans, to Metru-Nui

Metru-Nui
There, Yiolu accomplished his dream since he was born ; he became the best doctor in the entire city. Asked for everywhere, his talent prevented him from social interactions. He became an introvert for everyone in the city. However, being a celebrity, that didn't bother him, as people wanted to meet him, he didn't needed to go to them.

The Great Cataclysm
Yiolu sensed something wrong with Turaga Dume's order since the beggining. He tried to resist the Vakhis and ask questions to people next to him, so the Vakhis had no other choice but to use their Staffs of Obedience on them. They went to sleep, only waking up when the Toa Metru saved them.

The Island of Mata Nui
Waking up with amnesia, and being a natural introvert, Yiolu rapidly became an outcast in his village of Ta-Koro, althought his medical skills were somehow valuable to Turaga Vakama from time to time. The Matoran was angry to his very nature, and wanted this to be finished. However, by accident, he made a friendship with Le-Matoran Kualt while travelling to Le-Koro to heal someone. Shortly after, he met Toa Tahu, and then disappeared from the Island.

The Order of Mata Nui
Recruited for his medical talent, Yiolu first was intimidated by the other five Matorans summoned (Haikiu, Pykus, Destros and Rakama, althought since he was already friend with Kualt, it was fine), he rapidly adapted this newly formed team to their mission. Yiolu formed a plan of the team : while Haikiu, Pykus, Kualt and himself heals people, Rakama and Destros (sometimes Pykus when no surgery needed) cover them. Also, he outsmarted all of his trainers on basic medical and fight trainings. When they were sent to Karda Nui after their training, it was however not Yiolu, but Destros who was putted in charge, but Yiolu didn't care. His tips were still balancing Destros' decisions. When they began jumping from edges to edges of the battlefield and Matorans began to call them "heroes", Yiolu knew his work would never end. They continued giving medical care to the fighters until the Reign of Shadow began.

Reign of Shadow
During this dark time, Yiolu and his team (they began calling themselves "Junctus") were always on the run from Makuta's hunting parties. During that time, a terrible trauma rendered Destros unable to speak, which obliged him to resignate as a leader and put Yiolu in charge. Yiolu enabled a strategy of guerilla from now on ; ambush and cutthroat. It worked, and all Makuta finished to be on the run from them

The Battle for Bara Magna
During Teridax's invasion, the Junctus team stumbled upon a dark portal emanating dark energies. HWen they crossed it, they were inside a corridor full of Rakshis. Fortunately for them, the Rakshis were unagressive due to their programming. When they found their way out, tthe team went to heal Order's members and Toa from across the biggest battlefield ever saw. When they saw the fall of the Great Spirit, the team was full of grief, for he sacrificed everything for them, including his own life.

The Sacrilege
After 1146 years, the Junctus team decided to investigate Mata Nui's Robot to see if there weren't any valuable components left. While exploring it, they saw a strange phenomenon : ghost looking exactly like them. Moments later, they arrived at the center of the thorax, where they found a spirit form of Mata Nui, which told them of a Prophecy about a possible Apocalypse and the return of Teridax. As the last words of the Prophecy were said, energy began to be blasting from the Robot, and the spirit form of the Matoran used that energy to go into their physical counterparts body. It created a new team of Toa ... the Toa Junctus.

When they began repeating the Prophecy, very few listened. The act of going into the "sacred relic" was a sacrilege ; when they went for the North, following their Prophecy, the Toa had meager force to stop a dark threat, coming with the northern wind ...
