I love love love Tahu and don’t want him to die but I would really like to see Kopaka as the leader of his team or/and of other Toa because i have THOUGHTS
Agori leaders kind of think he’s a dick because he’s as stubborn as Tahu but twice as mean to other people trying to play politician with him. he once told a Glatorian to shut the fuck up in the middle of a resource allocation meeting
that being said, there’s something about Kopaka that the other Toa and Matoran really have faith in. he’s been Tahu’s right hand for a long time and now he steps up and never backs down when they need him to stand for them. he’s also a fucking ferocious warrior (and secretly cares really deeply for the people around him) and so he has the respect of just about every other Toa even before he’s leader.
Onua as his right hand because Onua softens Kopaka’s harshness but is just as steady as he is and is really reliable and good at making hard choices. Onua understands Kopaka well and is one of the few people who can keep up with his train of thought and anticipate what he needs.
I like to think an Ice Toa is a really unconventional choice for leader and people are always second-guessing him but he’s wild smart and has learned to listen to the people around him despite his pride
he rarely shows it but honestly it’s so much pressure on him to lead all these people. he feels like he’s not as charismatic or inspiring as Tahu and starts second-guessing his own decisions for the first time in his life because he’s bound to make mistakes no matter how hard he tries. sometimes he feels like it’s going to crush him. but he can’t let Tahu down. at one point, this probably causes him a legit mental break that he has to recover from
sometimes he wears the Hau in memoriam of his brother
he can be demanding but he’s honestly very hands-off with his siblings and lets them do just about whatever they want. they just learn to wait for orders in battles or tense situations and ask him questions when they’re not sure about something. they don’t really hide things from him because he gives them free reign. Gali feels like she needs a break and wants to go exploring for a week? he’s fine with that. bye. he trusts that she’ll make sure all of her responsibilities are taken care of while she’s gone. over time, they become more and more independent, but it’s because they trust so strongly in their unity that they know they’re never really alone in anything
in a battle - like a genuine, large-scale battle - nobody fucks with Kopaka’s orders. nobody challenges him. he’s savage and intelligent Onua is his strategist aid and so they always fucking win. Kopaka also kicks ass in most one-on-one fights he gets into as well. Gali always advised Tahu to stay out of one-on-ones, but at this point she’s angry and hurting and eventually she just tells Kopaka to go kick ass when anybody’s stupid enough to challenge him to a fight. since Agori are so used to the authority of duels, they respect this at least
all the others know that Tahu chose Kopaka to follow in his footsteps. from the moment Tahu takes his last breath, the others are looking at Kopaka to lead them.
he’s very responsible but also if he’s overwhelmed he WILL just get the hell out of there and disappear for days at a time. fuck anyone who tries to interrupt him when he’s like that. he misses Tahu and wishes he could talk to him again
the Av-Matoran absolutely adore Kopaka because he was the one who lead them in Karda Nui and Ko-Matoran think he’s the best ever. the Toa Mahri are completely loyal to him, the Toa Hagah love all the Toa Nuva, even Order members like Axonn and Helryx (is she still alive? bro I can’t remember. oh yeah she’s with Lewa but that Po-Matoran is going to try and kill her, right) think Kopaka is an adequate leader. he has a lot of strong allies
Kopaka finishes things Tahu started out of respect for the choices his brother made while he was here
people start rumors that Kopaka and Tahu really did hate each other even over all these years and that Kopaka’s just been waiting to lead. but Kopaka would have died for his brother to live. once he chose Tahu as his leader, he did not look back. this is one of the few rumors that gets to him.
he and Jaller start spending a lot of time together. Jaller sees Matoro in him and he sees Tahu in Jaller. when it comes time, Kopaka will let Jaller help him pick the Matoran who should inherit Tahu’s Toa stone
(and I love the other Toa Nuva too but if Kopaka was the last Toa Nuva I think he’d really become this legendary figure who’s so deeply respected by everyone and really trusted as a leader and advisor)
