Defang is formed from "de-" (meaning down or away) and "fang" (from Old English "fanga", meaning to seize or grasp). The word means to remove the ability to seize or grasp, particularly in the context of removing the fangs of a dangerous animal.
Think of 'removing' ('de-') the 'ability to seize' ('fang') — that's why defang means to take away the threat.
