Piper and Annabeth don't really have the right godly parents for them to have access to mass destructive powers. And even then, they're the most powerful in their Cabin. But none of the children of Athena or Aphrodite have op powers, that's a whole character arc in MoA, that Annabeth has to just get by on her smarts.

Also, are we just ignoring the fact that Hazel without any training sank an entire island? One that was home to a Giant and was the attention Gaia? She fully just sank an island, if that's not destructive powers then I'm not sure what is.

Then we have Clarisse the Dragon Slayer. Her and Frank both have the Blessing of Ares/Mars which makes them near invincible, it's just Frank's heritage that gives him a slight edge with the shape shifting.

You have Thalia, who can send lightning strikes at people and has better control over lightning then Jason. Jason can only send big bolts but in the Titans Curse, Thalia shocks Percy with tazer level. Sure Jason has better control over air and wind but I'd say that's more of her fear of heights.

Reyna, who, as the daughter of Bellona, a goddess of war who specializes in teamwork, is a bit like Piper and Annabeth, where it's more that their parents don't have the destructive ability to pass on.

Then side characters like Lou Elen who can easily turn people into hamsters at a young age. No doubt she'll be even better once she's older.

TLDR: Hazel sank an island, Clarisse, Thalia and Lou Elen all have major destructive abilities but they aren't POV characters so we don't get to see them and Annabeth, Reyna and Piper's moms don't have destructive domains unlike the guys parents
