Spider Core (スパイダーコア) is an electric, hovering spider web from Mega Man X4. It appears in Web Spider's stage. It will periodically produce a surge of electricity that can electrocute X if he happens to be touching it. The small spider robot (or robots) can also shoot energy spheres. If X destroys the spider, the straight part of the web will also be destroyed, leaving the circular section. The pole will regenerate if X moves to the other side of the web.
