First of all I am seeing we are taking into consideration all the aspects of the Final Fantasy games in which a villian is refered to so I am gonna start adressing power measures for the villians I think(based on facts) that are the strongest.

To start, In my book, Exdeath is the strongest villian in the final fantasy universe.

Reasons being are:

1. As stated in the original games, the warriors of Dawn could defeat him prior to his control over the void, but they could never kill him because he was inmortal(in all the meaning of the word) so they had to seal him.

2. When Exdeath gained control over the void he could "ERASE ANY PART OF THE EXISTENCE WITH JUST A THOUGHT". That statement alone tells you how powerful exdeath really is. In the game he erased many parts of the existence just by a whim and "technically" the heroes(but the plot saved the heroes before they truly dissapear and by that I mean the crystals they had were born from the void so that helpedto savethem)


3. The Void has been stated to be the nothingness that existed before the creation of the universe itself and also it is not bonded or follow any rules of the universe. As it is stated in the original game and in dissidia "THE LAWS OF THE UNIVERSE MEANS NOTHING" and we all know all Final fantasy universes, despite being separate from each other, they are connected in some way or another to the void. Examples being was Gilgamesh from FFV is heavily implied to be the same Gilgamesh which came out of the rift in FF8. Also the void existed or was mentioned in FF3 and in FFXIV still exist.


4. Exdeath in the original game threatens the party with "Erasing the universe out of existence" Which clearly indicates Exdeath is on a universal, if not, omniversal level of power thanks to the void.


5. It has been stated that the void is an infinite source of power and nothing can be greater than the void. So to tell you an example of how powerful the void really is(although we can't measure its true and full power since its infinite) I will put some comparatives examples based on facts.


a. It is stated in dissidia that Chaos was born from a military project and as chaos grew he became more powerful, until certain event made him open unconciously a rift which lead to the void and then they were threw to the dissidia world.

b. The whole plot in dissidia surrounding chaos was that Cid had to put Chaos as the bad guy, made him grow stronger and stronger during the cicles of was so chaos can become "POWERFUL ENOUGH" to open a gate to the void so he could escape from that world to the original world. And as you know, Chaos is portraited as the strongest villian(in terms of sheer power) in that game. So what do we have here is that beings like Ultimecia, Sephiroth, Kefka etc etc...they CANNOTcontrol the void with just "will" they need power or something "SPECIAL" (NEXT point)


c. In the GBA/IOS version of FFV, there was a powerful mage called Enuo, he was inmortal(pretty much like exdeath himself) and he had to give in his inmortality in order to control the void, so it was like a trade. So exdeath in the original game MAYBE(not implied or fact) had to give in something we don't know to gain control over the void and he controlled it just fine.

Also remember Exdeath lost because he briefly lost the control over the void and the void just erased him out of the existence, meaning that he is THE ONLY VILLIAN so far to have lost not because the party defeated him but rather his own power. It is also stated that the void is like a "sentient thing" so I doubt anyone can control it just because "he or she are powerful" AN EXAMPLE was chaos, he was unable to control it despite being stronger than Ultimecia, Sephiroth, Mateus etc...

Now to my next point, Things like "Cloud of Darkness" are not the void embodiment, they are more like intelligent beings BORN from the void like many other creatures. This is futher explained in FFXIV where these beings born from the void are called "Voidsents" these things have no power over the void but they can create catastrophes such that can kill the entire world.

In FFXIV, The allagans were an empire so powerful they could contain beings with planet buster capabilities such as bahamut prime, like they were just pets, they revive and replicate life, could create artificial beings far superior than Bahamut etc etc...could halt time and such. These beings invented a satelite that harvested the sun's energy for thousands of years only to be able to open a small rift that would lead to the void...that alone tells you how powerful the void is.


Villians like Sephiroth are super powerful and not to be understimated. It is stated that Sephiroth has NEVER fought 100% and that he is always limited or handicaped in some way or fashion. His will within the ff7 universe is absolute and nothing is stronger or above him within that universe. But even so, Sephiroth at full power might be more than a galaxy buster.

Ultimecia is almost omnipotent if she absorbs time and space, she is one of the most powerful villians in the ff universe, can even create magic by just thinking it. Due to her ability of time compression, she is at a universal level power. And multi universal if she has access to other world.

Emperor Mateus, at much he should be a planet buster not in the fashion as "blow the planet in one piece" but to burnt it to the ground just like Kefka and Kuja did in their own versions. The Emperor beat Satan and a version of "god" in his world so he must be really powerful when it comes to term of power, but Emperor Mateus best power is his intelligence. In dissidia he almost killed both the heroes and his own allies to ensure he was the only one surviving at the end. Consider him the doctor doom of Final fantasy.

Kefka is planet buster, reality warper, what else can be said? super powerful, he was a GOD

Kuja in my opinion is a bit overrated when it comes to facts, he is really powerful, but he is limited to planet busting levels of power.


Chaos might be planet busting considering that he has all four elements that controls the planet, he can create tsunamis, earthquakes etc...and destroy a planet with natural dissasters, other than that he is inmortal as longas the time loops exist and his sheer power surpass the other villians (raw power)

And finally there is Bhunivelze. This case is a little special. With the introduction of the god of light Bhunivelze, he puts himself really high in the villians tiers. He was born a god and was always a God,unlike most of the villians who achieved godhood by other means. Bhunivelze can create life and destroy it as it sees fit, he can even create someone almost as nearly as powerful as him(ereshkigal) and destroy it with a single thought. He can empower someone at such levels that acquires inmediate godhood(as he did with Lightning) he can super easily shatter multiple planets with just a wave of energy and he is EASILY more than a galaxy buster, in fact he can blow up multiple galaxies if he wants to.

Hypernova is one of his moves and a Hypernova can extend to a whole galaxy or more, is a massive destruction energy. He cannot truly die as well. He is definetely top 3.

It is difficult to put in order which villian is strongest but as the matter stands and I've shown you. Exdeath thanks to the void he reigns supreme, there is nothing that can beats the void as long as the void defies logic and all the laws in which all of the other FF gods are bound to.


As a final note: the chaos from FF13 is not the same as "THE VOID"the chaos in that game is just a dark place where the souls of the fallen roam for eterinity. It is like the final fantasy version of the "underworld" or it is like the world of darkness from FF3.

Bhunivelze fell into the chaos and did not die at all, if Bhunivelze would have fall into the void he would have been erased just like exdeath did.
