I am the wellspring of darkness, fed by Zemus's unbridled hate... I am He who is called Zeromus... I am he who knows naught but hate!

Zeromus is the final boss of Final Fantasy IV and the spirit and hatred of Zemus incarnate. Zeromus appears with three battle scripts, with only the third being possible to defeat. The party faces him in the Moon.

After Fusoya and Golbez defeat Zemus, Zeromus emerges from his corpse, proclaiming itself as Zemus's hatred. Fusoya and Golbez's attacks have no effect on Zeromus, and when Golbez tries to use the Crystal, the creature proclaims evil hearts cannot wield it, and attacks both with Meteor.

Everyone left at Mysidia prays for Cecil. Their prayers revive him and his party, and Golbez hands over the Crystal and beckons Cecil to use it. He does so, and Zeromus's invincibility disappears, revealing its true form.





Battle Edit

Zeromus will counterattack Rydia's summons with Osmose, and Black Magic and Holy with Flare. Zeromus will shake when he gets a turn, dispelling all status effects on the party. A Dark Matter can be stolen from Zeromus. It can be used to fight the superboss Proto-Babil.

Strategy Edit

Using summons prompts Zeromus to counterattack with Osmose, but this can be exploited; if used at the right time, Rydia's summon will cause a slight delay and counter with Osmose. However, this will not prevent Zeromus from using Big Bang immediately after.

Rosa should heal while the others concentrate in using their best attacks.

AI script Edit

If HP => 90,001

Turn 1: Black Hole
Turn 2: Big Bang
Turn 3: Osmose

If HP is between 30,001 and 90,000

Turn 1: Black Hole
Turn 2: Big Bang
Turn 3: Flare
Turn 4: Osmose

If HP <=30,000

Turn 1: Meteor
Turn 2: Osmose
Turn 3: Whirl

At all times:

If damaged by summon magic: Osmose (100%)
If damaged by Holy-elemental magic: Whirl (100%)
If damaged by any other magic: Flare (50%)

Zeromus absorbs Flare, presumably to halt what would otherwise be the most efficient method of dealing magical damage.

Zeromus counters Black Magic with Flare, White Magic with Whirl, and summons with a multi-target Bio.

Musical themes Edit

"Zeromus" plays during the final battle. It was rearranged and included in the Black Mages' second studio album The Black Mages II: The Skies Above.

Gallery Edit


Zeromus is an extended version of Zemus, which is Amharic for "Prayer". Perhaps because of the added 'Zero', it means "No Prayer".
