Dude he simply was an static huge target, completely harmless, anyone can land a hit.
Landing a hit is absolutely useless unless you can smash that Golem lol.
How many characters can do so? Certainly not the Tobi Roppo.
Besides, this isn't what I'm talking about - that's his ultimate Golem Form.
Pica too showed insane control when Luffy, Law, Zoro were invading the castle and also vs Zoro.
He also has full body Haki lol, just as Vergo.
Watch Pizarro also be a static Huge target in his all out form, which will be miles smaller than Pica's.
He's a Mid Trio fight like Franky's or Robin's or something. M3 even from Post TS are stronger than current Mid Trio & very likely after Power Up to beat BBP as well.
Meanwhile Pizarro this chapter says he wont engage in battle to not wreck the entire town, all while he moves around quickly like someone who has a pretty good control of his DF.
He literally made one small move from inside the castle to outside.
