@RangoBongo That's funny because the whole time I was reading this I couldn't think of it as anything but a painfully unfunny version of https://mangadex.org/title/23710, which isn't even that good. This doesn't even seem like a parody. It seems like it's genuinely embodying the "weak, but actually strong" trope, which everybody at least used to despise. The only difference between this and all the titles that started the trope is that this one is much more on the nose about it, which isn't a good thing.
For an example of how to actually mock this trope, see One Punch Man. Everything is normal aside from the MC. The jokes are subtle, and it doesn't beat them like a dead horse after telling them. People aren't yelling every panel, the world isn't one where humans would 100% be extinct by now, and there's little to no self-insert protagonist praising. Saitama also isn't a husk of a character like this one, who's entire personality is built around being retarded.
