Interesting to think of why the Turaga chose their respective right and left-hand Matoran. Like, Jaller was probably an obvious choice for Vakama, having been a good friend if his back in Ta-Metru… but Kapura? Being a bit of a misfit with some unusual capabilities, I think Vakama saw a lot of himself in the eccentric Matoran, and by elevating him to a respected position, Vakama is trying to make sure other Matoran won’t be bullied the way he was for his differences.

Nokama, rather than picking a former top student or respected teaching colleague, instead picked Macku and Kotu- a pair of free spirited pranksters who love weird sea creatures, to be her right and left hands. This may in part be pragmatic- she wants them where she can keep an eye on them, perhaps, but I like to think she wanted to be able to get input on her leadership decisions from the perspective of people very different from herself, especially since she was now going to be living far away from her brothers…

Onewa, I imagine made Hafu, former Master carver of Po-Metru his left hand rather than right in the hopes that it would take Hafu’s famous ego down a notch or two (lol nope), and Hewkii as someone with a complimentary skillset to Hafu’s to balance things out.
