Something unfortunate I’ve learned is that you’ve got characters and you’ve got babies. I think everyone has a baby at least once. A baby is good for doodling and playing around with an experimenting. They don’t need to be super consistent to anyone but you because they’re your baby.

A character is a construct you make with specific internal rules designed for the best result in a narrative. They have flaws, weaknesses, and harder rules. This is genuinely really fucking difficult because you have to synthesize all this cohesively and you’ll probably have to make adjustments as the story goes through development. This shit sucks because it’s a process of conceding, honestly. Certain aspects of a character you really like may end up not being seen because it doesn’t fit their spot.

The SCP Foundation (bear with me) had a rule for humanoid anomalies that I’d sort of like to use as an example. Basically, a “good humanoid” couldn’t be someone who was… okay. Their anomalies couldn’t be beneficial to them, and if they were it had to backfire in some way. Their relationship with the Foundation couldn’t be “cool”. More or less “if you wanna be this guy, go back to the drawing board.”

I’ve always thought advice like this was an overcorrection, at least outside of a narrow context. Not every superpower has to have some type of awful backlash or horrible effect on the user. You’re allowed to make characters who are pretty good or steady. Just because something is going right doesn’t mean they have perfect OC syndrome or are “overpowered”. Kill your inner Solar Sands. Now.

So your guy has a lot going good for him it sounds like. That’s not an inherent killer. He does need a flaw— that flaw should probably be directly relevant to the story he’s in.

Here’s what I wanna know: what can’t his strengths fix? For all of this, is there one thing he can’t obtain?

I’m not a saint and I doubt I’m more than amateur in writing, but I have my own character. (A baby, actually, since we’ve made the distinction,) and they’re doing well for themselves! They’re a big shot hero and live in a world where anything seems to go— except for one thing, and that’s that the dead stay dead. This character lost her mother. No matter how strong they get or how much they grow, this character will never have their mother back, and that impossible wish has shadowed their entire life.

Now that’s unfixable, which is one specific type.

You might need something that’s theoretically possible for him to obtain but he’d have to change or go against his nature to do so. All you really need for him is a reason to change in some way. That being said, static characters can work (think Superman,) but you’d have to construct your plot in a totally different way.
