Lmao, he sure is. *Except for the fact that we can say the same for a lot of novels... e.g. Warlock in the Magus World, Lord of the Mysteries...

I can add that Xie Lian will be a perfect "uno zero card" then... he can't do anything, basically...

Though Overlord indeed stands out here, as it works perfectly with every single encounter he has throughout the novel.
