I do not care how supposedly strong this boring, bipedal, plot contrived sentient lump of lard is, she is simply not effective as a genuinely interesting or even intimidating antagonist. She outright fails on every level.
She always plays second fiddle to someone else. In Whole Cake Island, she was side lined by Katakuri. In Wano, she got side lined by Kaido, Orochi, hell even Kanjuro's presence was treated with more weight, Linlin was treated like an afterthought plot line that simply needed wrapping up.
Linlin is consistently humiliated by damn near everyone she comes across and her personality is complete mess of contradictions.
She isn't interesting.
She isn't intimidating.
She doesn't even provide any decent fights.
She isn't even funny, just sad and pathetic.
There is practically no genuine fun or entertainment whatsoever whenever this morbidly obese clown is around.
So no, I really could not care less how strong she is because her actual character is completely and utterly garbage.
