Baku Baku also made Wapol almost unbreakable.
I liked Mr. 4, I kind of liked the concept of a baseball themed villain being a serious threat. And Lasso was pretty cool.
Mr. 3 was very competent with his ability, but you have to admit, if I was at a superhero meeting and my ability was the power over wax, I wouldn't bring it up.
Most disappointing? Well, it can go both ways; the power itself, and the way it has been applied. A while ago I would've said Ori Ori, but I kind of like it now. I disappointed in Ace's fruit, because it gave a boring character a really boring, unoriginal, and overpowered ability. I also thought Mr. 2's fruit was kind of stupid. Satori's LOL BALLS power was just a waste of time.
But I think the worst is Pearl. All he does is run around like the big flaming homo he is.
For most diappointing application, I'd have to say Mr. 5's Bomu Bomu fruit. I really like this fruit; it's in my top 3, but all Mr. 5 did was get bitchslapped around. I liked the idea of him doing shit like flicking boogers and firing his breath, but… he was just kind of a filler villain.
