Who Would Win: Zeref Dragneel vs. Meruem

This is a super close match but Zeref wins with a close victory.

Fairy Law

Meliodas doesn't have an answer to this. If you're wondering, Zeref does own this. Zeref taught it to Mavis, who then taught it to Makarov. There are several other capabilities associated with Fairy Law, such as:

Erasing someone out of time Using Death Magic A way to resist soul extraction

Meliodas has no way of killing Zeref, as even after death, he can reverse time. Zeref is effectively immortal and possesses a variety of magic, making him a formidable opponent.

Commandments and Capabilities

Most of Meliodas' commandments get negated by Zeref. Here's a detailed breakdown of some of the commandments:

Commandment of Selflessness

Zeref is not selfless. He has never shown any selfish tendencies.

Commandment of Faith

With regeneration and the ability to turn back time, Zeref is far more powerful than someone who can merely rely on faith.

Commandment of Pacifism

Even after death, Zeref can manipulate time and undo his actions. This makes him an unbeatable opponent in terms of pacifism.

Commandment of Truth

Zeref has never been known to lie. He only speaks when necessary, especially when conversing with Mavis and Natsu.

Commandment of Repose and Purity

The specifics of these commandments are unknown, but Zeref's magic and immortality make them irrelevant.

Commandment of Reticence

"Those who express hidden feelings or emotions will have their voices blocked" could be useful against the Commandment of Truth, as it prevents others from concealing their true feelings.

Commandment of Patience

The specifics of this commandment are unknown, but Zeref's infinite power and magic allow him to wait as long as necessary.

Commandment of Piety

Unlike Meruem, Zeref is not a coward. He doesn't back down from any challenge, displaying remarkable bravery.

Commandment of Love

Zeref demonstrated the ability to reassemble himself from magic when Ban was destroyed, showing his unbreakable bond.

Ultimately, Zeref's extreme hacks and infinite power make him unbeatable. Fairy Law alone, with its potential to cover everything, makes him the victor.

While Zeref is not universal, his capabilities negate Meliodas' commandments. And despite Meruem's speed and power, Zeref's infinite magic and immortal nature make him the clear victor in this hypothetical battle.
