The Blob is vulnerable to attacks directed at his face, as his eyes, nose, mouth, and ears do not have the same protection as the rest of his body. Dukes is also susceptible to psionic attacks and psychic manipulation, and he can be incapacitated by sensory assaults; for example, Banshee was able to render Blob unconscious solely through the use of his sonic scream. On another occasion, Sleepwalker defeated the Blob by using warp beams to wrap a steel girder around the villain, crushing his blubber and causing him great physical pain. The Hulk once took the opposite approach, harming the Blob by grabbing and stretching his flab. While he is all but invulnerable to direct kinetic attacks, such as punches, kicks or gunshots, he is susceptible to concussions and other harm resulting from sufficiently powerful impacts, as Daredevil knocked him out by luring him underneath a massive bell and then having it dropped on him with the aid of a young female mutant.
