Shonen anime has no shortage of overpowered characters with ridiculously strong attacks and finishing blows. The world of Dragon Ball alone is overpopulated with absurdly strong fighters and races, each with insane martial arts prowess and destructive energy-based attacks, and in some cases enough power to shake or even destroy entire worlds or universes at will.

Donquixote Doflamingo is one of the most complex One Piece villains
Donquixote Doflamingo is widely considered to be one of the best written villains that Luffy defeated in One Piece, not only because of his thought-provoking backstory that blurs the line between understandable and unforgivable, but also because he is a clear representation of the show's core themes of power and corruption.
Beyond the conflict between the marines and the pirates was Doflamingo, revealing another layer of conflict within One Piecefrom the illegal distribution of weapons on the black market to his nefarious connections to the world government. Even Doflamingo's String-String Fruit is a clear nod to his ability to pull the strings behind the scenes, from controlling governments to controlling his victims like a puppeteer. On top of that, Doflamingo is extremely charismatic, and his entertaining antics are part of what makes him a truly compelling villain in One Piece.
Some losses cannot be reversed, and Edward Elric knows just that Fullmetal Alchemist: Brotherhood later in the line.

Also, Edward Elric is not a flawless hero, and that's what adds to his appeal and makes his journey more compelling. He's loud, impatient, hot-headed, and even insecure about his height, but these imperfections never define him. What resonated with his fans instead was his alchemical wisdom, humility and relentless determination to right his wrongs.
