No, that's Kaido. This is not a universal thing.
Zoan Ulti is much stronger than Base Ulti and has more raw power than even her Hybrid form.
Zoan Page One is much stronger than Base Page One (Base Pay Pay has no notable combat ability feats to speak of).
Base Queen has done nothing impressive. All of his notable attacks have been in Zoan.
Base Jack wasn't impressive either, but he's less clear cut.
It was the same for Lucci, he used a single attack in Zoan form. However he fought quite a while in human form against Luffy.
Jack fought toe to toe with Inuarashi in Zoan form, when Nekomamushi arrived and slammed him into the ground, Jack reverted to his human form. Many evidences pointing toward Zoan form being the weakest form.
In Ulti's case, its more advantageous to use a bigger body to immobilize your target.
No, her Best feat is oneshotting a Tobi Roppo:
There's no indication that the Calamities are capable of that, especially not in their Base forms.
Do you keep the same energy with Apoo one shotting Luffy then?
I disagree. Jabra cannot defeat Daz Bones. Kaku would be able to if he could cut steel, otherwise no.
Daz Bones' own bounty was 75 million anyways.
That's a pretty wild take, you might bring hell upon yourself if Sanji fans see this.
Kaku is significantly stronger than Jabra.
I think i previously mentioned to be in agreement with that.
Alabasta Crocodile's bounty was frozen at 81 million. Oda said that it might be double that if the Marines had been aware of all the scheme
The Marines must know how dangerous he truly is if they offered him a Shichibukai position, so easily more than double.
