Warlord: Just because superman holds back does not mean he is hitting as hard as you or I would in a fight: a guy who can lift 200,000 tons of so is going to hit hard, whether he holds back or not

Cfp: those rockets are not going to compare in brute force to the punches of Etrigan alone, and there is not enough info above to distinguish as to whether the heat attack of Etrigan will be more powerful than those missiles.

Pach: Take it up with Cfp, who wrote the following:

Superhuman Durability: Hellboy's body tissue is much harder than that of a normal human. Hellboy can take large caliber bullets, great impact forces, and falling from great hieghts. One example is when Hellboy charged an MG-42 machine gun without hesitation. '''He is also naturally fireproof, though not to heat. '''

Emphasis mine
