It was more of an idea that popped into my head when I came up with the funerary rites pitch. I thought it might be a good jumping off point to figure out how to give Tahu and Kopaka some form of common ground.
Norio/Narmoto’s father is not a Toa, nor would it make sense for Toa to be revered outside of maybe a few spiritual castes at the time the story takes place. I mostly drew him with a bulky armored look to get a feel of the character.
Maybe his father’s efforts against the Vako are what push Narmoto to drive one into Ihu years later(at least in the sense that Narmoto won’t back down against the beast) Another idea I considered was what if King Matoro sacrifices his life to save Narmoto in the conflict and Prince Izotor came too late thinking that the Mangaian killed him? Perhaps Kualus could’ve been involved in some assasination plot trying to take advantage of the chaos?
EDIT: One more thing I think needs clarifying, if there was confusion about Norio being a possible Turaga of one of the five Mangai regions, in this universe the term is a title for a ruler rather than a subset of the Matoran species. Here, I get the impression that the Turaga are governors of Mangaian city states akin to feudal Samurai lords, though with less emphasis on bloodlines and more on fighting prowess
