Hellboy

He is not without flaws and likes to think with his fists at times, of course being a demon he can afford to be reckless as he is naturally durable and extremely strong especially in his massive right-arm, known as the Right Hand Of Doom, he is also prone to carrying a small arsenal of heavily-modified guns and other weapons that are designed to combat supernatural beings.

He is also fond of cats and keeps several as pets (in films) and has a passion for cigars rarely seen without one, he tends to be at odds with his superiors who wish to keep the supernatural largely hidden from the mainstream world to Hellboy such policies and procedures are nothing but a hindrance and his style of "diplomacy" is to shoot and ask questions later, not that he can't show restraint when necessary.

Hellboy is said to be both humanity's greatest ally and greatest threat as he has the power to destroy the world - although Hellboy has overcome his darkness their are continued doubts over whether or not he can ultimately stop the dark prophecy or not.
