Light Yagami

The well-written protagonist of the anime/manga thriller Death Note where he recieved a book capable of killing others with just their name and face. Ruthless, clever, and dedicated to his goals, Light occasionally uses brilliant schemes to get out of difficult situations, resulting in a massive fanbase. However, he is a bit of a fumbling troll, getting defeated despite having 2 magic books, 2 gods of death, and a cute simp girl on his side.

Dave: I can't imagine a world without Light Yagami.
Anna: Yes, that would be dark.
