I feel like a lot of fanon tends to miss what seem to be three pretty crucial things about Teru, and it's weird because they are easy to miss, but they're also so important that without them he's very superficial. it's part of why he gets so yassified almost every time he's adapted (see: manga into anime into fancontent)
one is that this kid is smart. on my first watch of his debut arc I assumed he was psychically cheating to be one of Black Vinegar's top students. now though I don't think so: firstly, I'll admit, because he doesn't actually seem to have a way to do that except blackmailing other kids for answers or something; but secondly because throughout the series he's just good at figuring stuff out. he picks up complicated psychic techniques more quickly and frequently than anyone else, including Mob. he was the one who almost beat Shimazaki. he figured out that Psycho Helmet was Dimple from the fact that he was a spirit who knew Teru's name, not a lot of info to go on. he draws conclusions in the somewhat haphazard but very clever way a detective does.
two, he's motivated so much by anger. this one's something of a hot take but it's so there to me that I can't leave it out if I'm Teruposting. before meeting Mob yeah he thought he was special and important for having powers but he was also extremely lonely and subconsciously mad at everyone else for not having them. he's the only one who has to deal with Claw he's the only one who has to live alone because his powers make it dangerous for his parents, he's the only one strong enough to be the shadow leader. he'll do it because he's the Protagonist but god he's gonna be pissed the whole time. it's not what he wants (we only get to see what he wants later with Mob and Reigen and everyone else) but it's all he has for a long time. seventh division shows the intersection between I Should Be Satisfied Now Teru and I'm Better Than These Guys Teru very nicely
last and kind of most important is his thing for Mob. I absolutely believe ONE wrote Teru to be queer and he definitely had or has a crush on Shigeo, but I also think that at least part of said crush is him misconstruing his adoration and the pedestal he's put his friend on. until after the Confession Arc, the two of them getting together would be really tricky and probably not good. Mob still feels bad about what he did at Black Vinegar for most of the rest of season one, and the only reason Teru changed in the first place was because of the cavernous gap in power between the two of them. until he declares Shigeo his rival and realizes that he has faults and any destruction he causes isn't perfectly righteous, Teru can't love him.
there's as much to his character as there is to the other main characters, and I get the easy appeal of the flattened version of him but when he's flanderized into this sparkly gayboy who's also sad sometimes, it makes me sad.
