* InformedWrongness: In volume 1 manga where the prototype version of Scratch (Mizuki, Naruse, and Kosuke) face a team assumed to be Syu's apprentices, Kosuke's slam dunk was disallowed for a charging foul (actually it is the defending player doing a blocking foul by standing in front of the basket while Kosuke is already jumping motion). Also, Naruse's shot was stopped with the audience saying that Naruse's shots can be easily thwarted because he doesn't do teamwork with Kosuke (actually the defending player commits a goaltending by catching the ball while it is on downward motion toward the basket). Both Naruse and Kosuke definitely have faults, but had Shades done his job properly as a referee, Scratch will probably still lose the match, but definitely not with 16-2 scoreline.
* TheScrappy: Shin from "J Invasion arc". He is perceived by readers as an obnoxious lowlife punk who cannot play basketball properly without dirty tricks. While some hardass characters with violent tendency such as Joker from Ice Picks or Yuta Higa from Kyan have their problems, Shin unfortunately is nowhere near as charismatic and skillful as either Joker or Yuta. Shin's behavior is even worse than his basketball skill. His SoreLoser tantrum when Scratch finally trounce his team is the final straw for the general readers. Shin becomes so unlikable, bad enough that according to WordOfGod, the author had to abort the plan to make Shin's FreudianExcuse flashback chapter. In the end, Shin fails to become more than a one-dimensional villain that comes and go.
