Kozuki Oden: The one and possibly single most retarded individual in the history of One piece. Also, he loses to every single Admiral or Yonkou. Absolutely useless.
Koby: Yes. In the recent time he got very overrated. Logically speaking, he should get his ass mid diffed by Boa if Oda doesn't want to fuck up the Power system anymore than he already has.
Who's Who/Sasaki: They think they're All star level and suddenly that means that they are ?
Drake acquired their rank in a single year and probably hasn't even showcased his full potential. Sit the fuck down.
Garp: He ain't a level above Sengoku, lmao. FA Sakazuki is probably already the strongest Marine in history. Garp acquired his notorious title due to a false report.
Monkey D. Dragon: While were at it, why not throw in Garp's son?
Dragon has been a major disappointment throughout this entire series. Present for almost 900 chapters, but has done nothing other than running away from Teach or sending his commanders into a suicide mission. What starts to annoy me with Dragon the most, is that he seemingly gained immunity. Meaning that no matter how much he disappoints, the people will turn a blind eye to that because he has the highest bounty and is Garp's son.
Might add others later
