Unfortunately for von Hammer, Hellboy was about 400 pounds of solid muscle and power, so he didn't lose his balance that easily. Fortunately, on the other hand, with all that power came not the best reaction times, so when von Hammer ducked, Hellboy just slammed his fist into the wall instead.

Stone yielded to stone, and Hellboy's indestructible fist cracked a hole in the castle wall down to his elbow. With a furious, incoherent noise, he pulled himself free and turned back around.
