Maybe make it so AFO reavealed the information to him, to turn him evil like Shigaraki. It would show that AFO was searching for info to destroy the hero society from the root.

Well since he is going to become a hero, it can't just happen without reason. However it's not late to make it that he found out that his parents were forced to adopt him by the goverment to make him a biological weapon. This woul give you a solid reason to change the whole story's direction.

and once the goverment found about this quirk they kidnapped him, made him absorb the power of the sun and turned him into a battery for their own benefit. The heros were unable to save him due to their position as civil servants. Then one day he freed himself and destroyed the world since he is a walking, reusable nuclear bomb.

Not gonna lie, I liked the honourable way he treated war. Even if it’s unrealistic.

I doubt it. The whole fanfic is centred around a guy that is obsessed with Tsukasa. It should be taken for granted that he will share everything with her.

As for this part, even if he knows that his siblings are way stronger than him it doesn't mean that he can take the risk. The fact that there are spirits of his level, he is unaware of makes it possible for his family to be attacked. He can't be sure if the fight would lead to complere erasure or just a period of separation until his siblings are reborn. He can't be sure that the spirit that will come back will be the one that was taken away. He doesn't have enough knowledge yet, which is ironic considering it's his concept. Plus internal fights can take place, he has seen Vaatu and Raava kill each other every 10 thousand years to decide the worlds fate. Just because Wan and Korra sealed Vaatu and I haven't shown them actually kill each other it doesn't mean it never happened.

Answers: 2) The fact that he is born with a complete concept makes him a concept-level spirit, however his inexperience and inability to utilise and understand his concept holds him back in the power department, effectively making him a baby holding a nuke. He has immense power but he is unable to use it. 3) I am planning to make him understand his powers through experience without spoon feeding him everything. 1) The concept-level spirits are indeed something akin to gods, however you must remember that Solon is only 100 years old. That makes him an infant that can influence the world itself. I have shown them as human like in order to use it as character development. In this story I aim to make spirits act with no care about infants, only humans care about kids. If the other concept-level spirits allow Solon to do whatever he wants without showing care they would have a emotionless spirit of their level that could potentially lead to catastrophic results. As such they teach him how to feel real emotions. As for the death part, for a spirit to come back millions of years are needed as well as a concept that is nessessart for the world to run. Solon is young, which means that time passes way slower for him in comparison to the others as such it’s less of fear of death and more like fear of separation.

Yes

Now imagine if the Hero Public Safety Commission knew about this power. They would make him a bological weapon.

So is this how he unlocks his real powers? Is the plot protecting the doctor because he is useful?

How about habing him help with searching for rick prime.

And this is how an type 9 immortal omniversal traveler with saitama’s strength was born.

I think he can control freely what he stops after all, he could touch Jogo freely but Jogo couldn't move his hand no matter what.

In my opinion they should be equal in power. But dust release would come on top in a fight since it's easier to use and doesn't need the six eyes to work. It's also better when you try to keep the fight contained since purple destroys everything in front of it while dust release provides controlled destuction.
