Pica is one of the most underrated characters in the entire series where people have to talk out of your their ass and literally ignore the obvious manga panels to downplay him
Attack Power
-One casual punch form the Golem that wasn't even as big as the final Golem launched the town and created shockwaves that span the majority of the island and those shock waves sent all of the Marines (who he wasn't even aiming at), Zoro, Luffy and Law flying
-He has extremely lethal spikes that nearly killed Chinjao, Harjudin and a few other grand fleet members
-In the split seconds he turned the entire architecture of flower hill creating spikes all over it
His attack power makes ever commander look like trash forget about Veteran level
Defense
-King Punch was supposed to be strong enough to defeat even an emperor yet Zoro told Elizabello it would be useless against Pica as he would quickly regenerate
-Zoro can bust a fucking mountain yet had to find Pica at he right spot by lifting him in the sky to finally take him out
-Luffy used his strongest one shot G3 attack and all it could do was break Pica's face
Range
-Pica's range spans across the entire Island
Speed
-Pica is exceptionally fast inside his golem
-Even his own Golem's speed is underrated as his punches create island wide shockwaves that Zoro and Luffy couldn't out run. His spikes were so fast, Chinjao couldn't react to them and nearly died
CoA
-His CoA was given similar portrayal to Vergo in Vivre Card
-Is one of the only two characters in Manga to have Full Body Haki
Portrayal
-Pica took 1080 pound cannon to the face and was fine seconds later yet Killer got one shot by one of Zoro's weakest 3 sword attack while Zoro was missing his strongest weapon
-Viola said it is all over once Pica showed up yet didn't nearly show that level of fear for Diamante who I consider Veteran level. Pica himself called Diamante pathetic trash.
-Doffy had so much confident in Pica that he didn't even stop him when he said he will go fight Fujitora. People over wank Vergo for Doffy having confident in him.
-Zoro vs Killer was such a one sided slaughter, even with Gyukumaru's interference and Zoro missing his strongest weapon and his main fighting style got low mid diffed showing if Zoro actually had Shushui and it was 1v1 Killer would get low or no diffed.
-Zoro vs Hawkins was a one sided slaughter as well where Hawkins lost his good card to casual 2 sword Zoro and his fight with only defensive Zoro resulted in him dying twice. In a serious fight, ISDS would probably take all 10 of his lives considering how massive a gap is between a casual Zoro slash and ISDS and Kizaru's light speed kick took two lives while simple laser took one life
-Pica on the other hand basically required Zoro to use all his Base arsenal and even need Orolumbus' help.
Pica in Dressrosa shits on any Veteran level characters like Page One, Daifuku, Oven etc no or neg diff
Sanji, Vergo, Judge, Killer and Hawkins who I consider YC4 level don't stand a chance and get low or mid diffed
Inurashi, Ashura Doji, X-Drake, Nekomamushi who I considering YC 3.5 also loose mid/high diff
I have seen Cracker's entire offense and from what Jack has shown, YC3 don't seem to have answer for dressrosa Pica either. But I will give Jack the benefit of the doubt that in hybrid form he can do some damage and defeat Pica
I'd say Pica is between Inurashi and Hybrid Jack.
