First, I'd like to say that I find it really odd that people don't like Wapol's fruit. Wapol threatened repeatedly to basically eat everything that could ever inflict pain EVER and use it all. Can you imagine that? He could've given Crocodile a run for his money! Besides that, he could rearraange his bone structure and organs - not just to make him skinnier, probably. Anyone else ever watch the old Pokemon cartoon with Ditto in it, how it alwaysa had an incomplete face but everything else was perfect? Dress Wapol up and the only giveaway is the jaw!
… Which, you know is a pretty big giveaway, but still.
Next, about Ace. I think we need to trust Oda with him. I thought that Enel sounded too much like Crocodile at first, but when he turns into the big God beast... And all the gold melting, all of the chemical terms and everything... Not to mention he could read people's freaking MINDS! Ace will definitely have some polish and finesse, knowing who the author we're talking about is.
I agree that Blueno is more a specialized Devil Fruit than anything else, but I still think he's an amazing fighter because of his fruit. Even in a toddler's body, if he weren't so cocky, he could stomp all that oppose him just by keeping them closed in trap doors so they couldn't move and just punching them until they went down - no matter how many hours of sraight punching that would be. Also, the revolving door to the face that he did to Luffy was amazing. What if he just kept it spinning forever?
Finally, Foxy. Foxy constantly says that a game is different than a fight, which is completely true. If you slapped a Noro Noro Beam onto Luffy, would it work? No, not at all, because Luffy's lifestyle calls for constant beat-ups, straight up with no tricks. Foxy's lifestyle is all about the Davy Back Fight... and a slightly rigged one, too. His power perfectly suits his lifestyle, when you consider the Davy Back games. It's perfect for the Donuts Race, and considering the cannon choosing the arena is rigged to fire at his own ship, with traps designed for the Noro Noro beam, it's perfect for that, too. Just like Doa Doa is made for assasins, Noro Noro is for... Foxys?
Next, about Alvida. Hers is amazing just because you can't touch her. Every attack will slip off her, except maybe Logia fruits. Maybe. And even then Crocodile's is useless because it's a bunch of small solid things. There are some things that are designed to make fire just slip right off, mostly used on stuntmen, and so Alvida could be so slippery even Ace couldn't hit her. The only ways I could see her being defeated is if Smoker covered her in smoke and made her die of asphixiation, Aokiji completely froze her solid, Enel fried her to a slippery crisp (maybe this one wouldn't even work), or seastone.
Whew. That was a mouthful. I'd just like to say that I don't mean to attack anyone's opinions here - this is just why I disagree and just my reasoning. That said, I think the most useless power is Laboon's. The power to hit yourself against a rock cliff day after day without stop until some kid paints on your head? Laaaaaaaaaaaaaaaaame :laugh:
Of course that was a joke, but my point is that really none of these powers are that lame... Unless they're supposed to be. I guess I just can't decide, because the only characters in this entire series that I've ever not liked were Mr. 7 and Ms. Father's Day. Don't ask why.
