As the final boss, Zeromus is a dangerous opponent. He has two signature moves, Black Hole, which nullifies any status effects (positive, or negative) on the party, and Big Bang, which does massive non-elemental damage. He also has access to Bio, Flare, and Meteor. In the Advance and The Complete Collection releases of Final Fantasy IV, Zeromus EG appears in the Lunar Ruins as an optional superboss. He knows several elemental and status spells along with the original Zeromus's Black Hole and Big Bang.
