I wouldn't say I'm a fan yet, per se. I just think he's a badass undercover agent for now.
His potential is very interesting. Resenting pirates because of abusive pirate father, loyal to marines that saved him, learning about "dark" marine business, joined Sword, and now joins Luffy's revolution. He's an important side character for future new Marine regime after Luffy takes down current regime.
