Kizaru made G4 moot, and stalemated G5, as a side gig during the arc. Any shortcoming he had afterwards Oda excused with the VP plot. Nobody and I mean nobody, gets disrespected like BM. She is Oda's personal punching bag, atleast with Buggy he has him pull off miracles, with Big Mom she just gets clowned with very little upside. 2 arcs of complete clowning for Big Mom, and the payoff? Misery....bruh. I'm not even a Big Mom fan, and I was beyond disappointed with Oda.
You should be ashamed of yourself even defending this rn.
It makes no sense to bring her back, when she got clowned in arcs where the characters were much weaker and the focus on her was much greater.
