It honestly feels like Oda goes out of his way to deconstruct the Yonko as legitimate characters.
Linlin goes from intelligent, intimidating, unreasonable, unrelenting entity of pure calculating greed to a bumbling, incompetent, pathetic, consistently humiliated, screeching retard.
Kaido goes from war loving, battle lusting, death seeking, suicidal entity of raw intimidation and power to a spineless, gutless bitch that gets all shook up whenever he loses a fight and starts whipping out hostages for cheap shots.
Worst of all, Oda has just turned Whitebeard from a steadfast, loyal, caring man whose morals and ideals remain unyielding even in the face of overwhelming odds, a man who would sooner break his very body before his word into a fair weather friend who will situationally assist you if he even bothers to remember your existence within a time frame of two decades.
The sheer amount of character assassination that occurs within this group is astounding. These characters should represent the pinnacle of One Piece characters yet Oda consistently undermines the Yonko both as individuals and as a group.
