In the first half of 2009 I would have continued the story in the MU, and have 24 sets
The story would be that 6 matoran have decided to go rgue and try to fight back Makuta in the southern reagion unexplored previously, There would also be 6 new toa who would defend what was left of the MU and the OoMN. As well as having 12 skakdi warriors who would fight against this new team of toa.
6 Independent Matoran who are on a mission to explore the southern land masses to try to find a safe place to rebuild, or to fortify from the Makuta Teridax and try to fight him back.

When Mata Nui crashed down onto Bara Manga he had rebuild himself and was followed by Click (who would be in the Mata Nui ser) he would get the attention of Mata Nui and Mata Nui would then put click on his shoulder. But unbeknownst to Mata Nui he is actually being stalked by a Zesk, Mata Nui then stumbles to Volcanus when we is questioned at the gate, but it eventually let in by Raanu, believing that the battle that would soon occur in the arena would help calm down Mata Nui from his panic.
In 2010 the six matoran have met up with a young rogue skakdi, 4 more matoran, and 1 new toa. together they would travel farther down to the south and would get into a scuffle with 6 Skakdi Warriors, but the goup would outright slaughter the 6 skakdi and continue on.
