WARNING: Mafia idea approaching!
MU MAFIA: The South
While the Makuta and their Rahkhshi were exploring the southernmost land of the Matoran Universe, conquering and killing the natives, a few Toa of Ice, all of whom wore the Great Kanohi Mahiki, planned a rebellion against their Makuta invaders. The Toa crept slowly into the Makuta's camp, transforming themselves into Makuta with their mask powers. However, a Makuta sentry spotted them. Easily outnumbered, he attempted to flee. With a swift blow from a Rhotuka Spinner, the sentry fell, his body limp and lifeless. The Toa, now fully disguised, walked up to the corpse. One of them pulled out his Toa Tool, a hammer. He gathered all the strength he could muster and smashed the sentry's mask. The Makuta sentry wore a Great Kanohi Rode. The only Rode available to the other Makuta.
Standard Rahkhshi: The basic Villager unit.
Standard Makuta: Another basic Villager unit, but less common than the Standard Rahkhshi. (xSR>SM)
Rahkshi Sentinel: A Rahkhshi with higher quality armor and weaponry compared to the Standard Rahkhshi. Each night, the Rahkshi Sentinel can select a player to protect from Mafia assault. (x1)
Suletu-bearing Makuta: A Makuta who bears the Great Kanohi Suletu. Each night, he can activate his mask power to read a player of his choice's thoughts, revealing their role. This Makuta is more secretive than others, and therefore cannot share his findings. (x1)
Makuta Raid Leader: The leader of the traveling Makuta. He needs two Mafia assaults to kill. (x1)
Mahiki-bearing Toa of Ice: The basic Mafia unit. (x3)
Deceptive Toa of Ice: A Toa of Ice with a lower level of Light than the other Toa, making him more deceptive and treacherous. He can avoid only one execution. He smashed the sentry's Rode. (x1)
So those are my ideas. Not sure if this'll actually be a thing or not (considering I didn't ask permission).
