NGL, pretty awful "double speak." Talking about a "BIG TURTLE" and saying he's never fought a "prefect one like me" while referencing KILLER BEE and YAGURA, the two people who are famous just for being PERFECT jinchuriki. As a completely ignorant outsider, I'd come away from this knowing he's a perfect jinchuriki of the 3 tails with basically no thought needed.

I just realized that the jake jake no mi + a giant + hasshouken = Sengoku's Buddha fruit

Her hair's probably platinum blonde, which is basically white

He's not tricking the stone, he's gaming the hatsu.

C. Baldur's already strong, what he needs is a qualitative change in power (e.g. Odinforce) rather than some quantitative increase. Absorbing the power and divinity most likely wouldn't make a dent in his chances against Odin or similar characters.

Also for fire, just ignite the whole area the villains are in on fire instantly like he did to the second floor in the combat training. If his fire also has any explosive force you could spark tiny explosions next to an enemy's ear to burst their ear drums and destroy their balance with minimal effort. For water you can just surround the enemy's head with water and flood their lungs so they drown. They can't rip it off, so the only way to deal with that would be to move fast enough to escape it, which they likely couldn't do if you'd lifted them into the air. For earth he needs to be more comfortable moving through the earth and also moving others through it. Sinking someone into the earth up to their neck like kakashi did in naruto would be extremely effective. Quicksand, sinkholes, bogs(with water), and sinking or raising the ground where you opponent is about to step to throw them off balance would also be useful.

Just use wind to lift the Nomu off the ground. Without something solid to leverage its strength against, and with no means of long distance attack or flight, it's helpless.

Set a negative multiplier and he can heal himself

Has Ren learned Shunko yet? I thought the only reason he didn't use it was Khorne.
