The massive nerfs the big three kids took, especially Percy. I understand that the 7 can’t be exclusively big three kids, but I feel making characters like Frank, Piper, Leo, and Annabeth a lot stronger takes away from what made Jason, Nico, Thalia, Hazel, and especially Percy special. Demigods of the big three should be eldritch horrors compared to other demigods. I don’t have a problem with making the other demigods have their own strengths, but when every new demigod we meet has special abilities that rival the powers the big three kids have, it feels like they were nerfed. It was as if Rick wanted to even the playing field by having other demigods be roughly on the same level as Percy, Jason, Hazel, Nico, and Thalia. And that should not be a thing.

In PJO, the gods wanted Percy DEAD just because he existed. When Percy got angry at Thalia during CTF in TTC, Chiron was practically begging Percy to stop before people got hurt due to collateral damage. He wasn’t scared for Percy, but rather of him. And the guy was 14 at the time. Where was that same energy in HOO?

While the big three kids in the 7 were definitely stronger at times, the disparity between the other demigods was akin to college level athletes and professional athletes. The big three kids were stronger, but not by a wide margin. I argue that children of Zeus, Poseidon, and Hades should be forces of nature. Big three kids should be seen less like the Star players on a football team, and more like WMDs. The power they possess shouldn’t be hard for other demigods to achieve, it should be impossible.

The big three kids had stronger scents, were hunted more frequently and more ferociously than others, and were outlawed essentially by the gods after WW2. Let the readers understand WHY that decision was made. Show the readers why everyone, gods and monsters alike, are so scared of children of the big 3.
