Since it's about time to do so. Here are my personal guesses to who will win. Bolded is victor. Brackets is my vote (subject to change.)
01. Buggy vs (Rayleigh)
Buggy'll take it easy. Personally I think Rayleigh is one of the most coolest chars in the series. Besides. I like the Dark Night more than the Joker.
02. Dragon vs (Enel)
easy choice. Enel has a huge following and is pretty much awesome. Dragon is about 70% hype really. Still awesome tho.
03. (Garp) vs Going Merry
Finally Merry goes up against a real char. I love Merry but I love Garp even more.
04. Smoker vs (Arlong)
It'll take a lot for me to vote Smoker. However I'd imagine he'll win due to the badass vote.
05. (Ryuma) vs Whitebeard
Boring Swordsman vs Whose Ya Daddy
I thought WB to be all hype and no deliverance. Ryuuma was....well Ryuuma wasn't much better. He had another omake however. Which was nice. Never gonna vote WB unless he goes up against Croc or Zoro
06. (Kuma) vs Sengoku
Sorry Sengoku. While having an awesome Goat(and a Goatee) Kuma is just so much better
07. (Chopper) vs Gun Fall
Do I really need to say why?
08. Bon Kurei vs (Crocodile)
Bon was awesome and beat Sanji. As well as being an all-around awesome dude.... Croc was awesome back in Arabasta but I thought he sucked so much since. He has the fangirl vote however so he'll win.
09. (Robin) vs Bellemere
Tragic Past vs Tragic Past. Robin has the Mugiwara vote and the hotness vote.
10. Moria vs (Shanks)
Moria is just that damn awesome. However Shanks is hugely popular. Would love to see an upset tho.
11. Norland vs Bepo
Don't know. Don't care. Only match I care so little for either char that I'm not voting in. I guess....Bepo?
12. Magellan vs (Luffy)
Luffy. Easy choice. While Magellan is just downright awesome. I can't go against Luffy. The best one to knock out Croc or WB from winning
13. (Hiriluk) vs Hannybal
Another one of downright awesomeness. It's gonna pain me to kick out Hannybal but it's for Chopper's Mentor/Santa. How can I vote against Santa!?
14. (Roger) vs Brook
Roger, while giving us One Piece plot. Also spawned us Ace. Brook has been nothing but awesome since introduced.
15. Mihawk vs (Zoro)
16. (Nami) vs (Usopp)
Love them both to bits. While I'd love to see another girl get to round 4 I don't want Usopp gone either
There. That wasted a good 10 mins.
