Incorrect Predictions: 2 (05, 07)
Maybe I'm not so bad a this after all.
! 10. Shackey vs. Marco (Both popular characters, but Marco has a very awesome ability)
11. Calgara vs. Usopp (Poor Calgara gets pitted against a Straw Hat in Round 1)
12. Going Merry vs. Kaku (Could be close, but Merry has sentimental appeal that's tough for Kaku to beat)
13. Crocodile vs. Rob Lucci (Croc is very popular here)
14. Ivankov vs. Doma and Monkey with a Gun (I don't even remember who Doma is)
15. Chopper vs. T-Bone (I suppose there's an "anti-Straw Hat" voting block, but I think they're not as large as they sometimes seem)
16. Iceburg vs. Ace (Ace's death ruined what chances Iceburg might have had)
17. Red-Hair Pirates vs. Gecko Moria (Except for "Pwngoat", nameless people rarely do well)
18. Hancock vs. Kureha ("Recentness bias" plus a large Hancock fanbase plus some clever Hancock campaigners in the prelims)
19. Mihawk vs. Momonga (I predict at least half the Shichibukai will win their Round 1 matches)
20. Nojiko vs. Gun Fall (For reasons I believe we're forbidden to discuss)
21. Pwngoat vs. Marshall D. Teach (Could be close, but when you strip away Pwngoat's silly meme, what's left?)
22. Norland vs. Hiking Bear (Does HB even count as a character?)
23. Cricket vs. Drake (Supernovas tend to do well, and Drake did decently against Nami last year)
24. Vista vs. Magellan (Magellan has more memorable personality and abilities)
25. Thousand Sunny vs. Kid (Sunny is a Straw Hat, after all)
26. Tom vs. Smoker (Both very popular, but I think Smoker has more fanatical supporters)
27. Buggy vs. Foxy (Similar kind of character, but Foxy is generally considered annoying while Buggy seems to have a lot of fans)
28. Gaimon vs. Whitey Bay (The Whitey Bay campaigns have already begun)
29. Clash of the Titans: Stronger vs. Banchi in 3-D (Banchi has some very vocal supporters)
30. Mr. 3 vs. Duval (Mr. 3 is just too popular)
31. Enel vs. Kuina (Haven't seen many devoted fans of Kuina)
32. Bon Kurei vs. Yasopp ((Almost) everybody loves Mr. 2)
33. Franky vs. Luffy (Last year's winner is unlikely to lose so soon)
34. Yokozuna vs. He-Man (He-Man is just a face and a catchy nickname, not an actual character)
35. Sanji vs. Shiryu (Am I underestimating the chance of a Straw Hat losing? Maybe, but prelim vote totals suggest Sanji is pretty popular)
36. Hattori vs. Gin (Gin has a lot of fans, and Hattori is just a pigeon)
37. Basco Shot vs. Shiki
38. Joz vs. Crocus (Recentness bias)
39. Zeff vs. San Juan Wolf (After looking at prelim votes, I've changed my mind on this one)
40. Inazuma vs. Roronoa Zoro (Poor Inazuma)
41. Shanks vs. Capone Bege (Another landslide, probably)
42. Bepo vs. Wiper (Recentness bias)
43. Arlong vs. Hatchan (Hatchan is like Arlong, but less evil, more involved in recent events, and with a wackier personality and powers)
44. Tashigi vs. Jaguar D. Saul (Saul has quite a few fans)
45. Genzo vs. Beckman (He's the smartest man in the world, after all)
46. Brook vs. Margaret (Although Margaret might actually win if she does enough in the manga soon)
47. Dragon vs. Jabura (A faction leader implied to control the weather vs. a CP9 member with yet another zoan power)
48. Carue vs. Dorry and Broggy (Even many people who don't like Vivi like Carue)
49. Hawkins vs. Mr. 1 (Mr. 1 JUST CUTS)
50. Aphelandra vs. Van Augur (Neither has much personality, Aphelandra has a love-it-or-hate-it character design while Van Augur has an OK one, and Van Augur has a cooler weapon)
51. Roger vs. Pandaman (Roger is another top-tier guy)
52. Nami vs. Doctor Black Beard (A Straw Hat vs. a character who's mostly just a meme)
53. Urouge vs. Lucky Roo (I know Urouge has lots of fans even though I don't really know why)
54. Coby vs. Kung Fu Dugongs (Not long ago this would have been a close call, but after the Marineford arc Coby has a better chance)
55. Doc Q vs. Jesus Burgess (AMV power!)
56. Olvia vs. Rayleigh (Rayleigh got the third-highest vote percentage in the prelims)
57. Sadi vs. Killer
58. Paulie vs. Trafalgar Law (Law was always popular, and now he has recentness bias is his favor)
59. Kuma vs. Laboon (Recentness bias plus Kuma being a Shichibukai plus his cool powers)
60. Kizaru vs. Makino (Admiral with a cool power vs. minor backstory character)
61. Jewelry Bonney vs. Richie (Richie always does better than you'd expect around here)
62. Jinbei vs. Johnny and Yosaku (Pretty one-sided)
63. Hannyabal vs. Calico Yorki (Used prelim match statistics because I don't have any other clues that come to mind)
64. Donquixtoe DoFlamingo vs. Nico Robin (One of the more popular Straw Hats, though it's still a close matchup)
