Generaid Core

Generaid Core (ジェネレイド・コア) is the mid-boss of Storm Owl's stage in Mega Man X4. X or Zero encounters it right before he confronts Storm Owl. It is the core from a giant battleship. Its weak spot is the red core, which is vulnerable to Lightning Web and Rising Fire. The core won't attack directly, but the Beam Cannons encountered earlier in the stage will. The core will also close occasionally, so the player must time their shots.
