Well, Hellboy survives jumping out of planes without a parachute, severe beatings by demon-gods, being EATEN by an Iron Maiden brought to life by the spirit of a goddess, he heals more quickly than a normal human obviously, maybe not up to par with Logan, but close. The Right Hand of Doom has several ton strength, im not sure if there's an exact number, and the Good Samaritan itself isn't that powerful, but the special bullets it uses makes it powerful.
True, Wolverine would win probably if he went into berserker rage mode. Yet Hellboy has the Good Samaritan and its powerful bullets to keep him at bay for the time being and if Wolverine gets close enough then Hellboy would be in trouble. Yet again he has the Right Hand of Doom.
I would have to go with Wolvie after a hard and close battle.
What about u guys?
