Nico di Angelo's power is beyond comprehension.

I doubt that in the Last Olympian Percy was far into Nico to described everything he was doing, considering he was fighting off the army himself and trying to slow down Luke (Kronos) from getting to Mount Olympus. As for Nico's participation, I don't think he was going all out, considering that epic quote Percy gives Nico afterwards, the whole showing up to battle with an army of undead soldiers your everyones friend!

Now we also know their is a time skip between then and the Son of Neptune, so that would also increase his powers even more. Percy and Annabeth only saw a few things that Nico could do, and even Percy seems to be freaked out at times by him. I think Annabeth also mentioned something like that. So yeah, Nico is underestimating his powers, I mean he's the son of Hades, god of the undead, king of the underworld. Also the famed Ghost king who is he kidding. He's beyond strong. I'm more interested in how Hazel and the others will describe his fighting style will it be Greco-Roman or just Greek?

I also enjoy the fact that we don't get a POV from him, I mean he's always been mysterious why start telling secrets now!
