Mahāpralaya

is Arjuna Alter's Noble Phantasm. Another one of the powers bestowed to Arjuna together with Anti-Evil. That’s this Revolving Sword that Adjudicates Reoccurring Destruction.
In order to exterminate evil, in order to make the world end, he wields and brings peace with his sword at the end of all. If he swings his sword, he annihilates the entire world.
Mahāpralaya points at the re-annihilation of the Universe when Brahma dies… In other words, the .
It is a massive attack capable of destroying the entire world. As the last god of the Indian Lostbelt, Dissolution and rebirth... Destruction and reconstruction... Cataclysm and genesis are within his capability. To destroy and remake everything in the Indian Lostbelt, Arjuna Alter extracts the unified divine power from all Divinities inside him, and condenses them into a sword, using a tenth of it to control its execution. Just while beginning to charge this attack, the amount of Magical Energy gathered by Arjuna is so unbelievable that Sherlock Holmes states that calling it a Noble Phantasm wouldn't be enough to describe it. He says that it is like nothing he has ever seen, and its sheer power overloaded several sensors of the Shadow Border while trying to measure it. Although Holmes still doubted that it would be powerful enough to destroy the Lostbelt while he was charging it, he agreed that if the enormous mass of energy were to keep growing at an accelerated rate, it wouldn’t be out of the realm of possibility. The reason why it takes Arjuna so long to charge it is that he needs time to gather the ridiculous amount of energy necessary to pull it off.Fate/Grand Order: Cosmos in the Lostbelt - Yuga Kshetra: Genesis Destruction Cycle, Section 5: Kali Yuga/A Revolving World
Arjuna uses his power to destroy and recreate the world over and over, cycling it through periods called Yugas. Although similar in some ways to India’s original conception of yugas, they ultimately diverge pretty widely. Ordinarily, it would take Arjuna hundreds, or rather thousands of years to complete each yuga cycle, however, thanks to gaining power he didn't have before from the Fantasy Tree, it became possible for him to shorten the length of each cycle to 10 days.Fate/Grand Order: Cosmos in the Lostbelt - Yuga Kshetra: Genesis Destruction Cycle, Section 6: The Relic Called FalsehoodFate/Grand Order: Cosmos in the Lostbelt - Yuga Kshetra: Genesis Destruction Cycle, Section 11: Treta Yuga/Asclepius, the God of Medicine Arjuna doesn’t remake the world from scratch every time he resets the cycle clean. Instead, he treats the world like a model, adding new parts and removing old ones he considers "flawed" or "evil". The people there are not dying and being brought back to life afterward. Their souls are instead saved as data, and their memories are modified when they are put back into the new world. This is a much smaller-scale feat than creating the universe from nothing. However, Da Vinci states that it is still an undoubtedly absurd feat, made possible due to Arjuna having every Indian Divinity and support from the Fantasy Tree.Fate/Grand Order: Cosmos in the Lostbelt - Yuga Kshetra: Genesis Destruction Cycle, Section 7: Return of Paradise/The Shape of Evil to be Cut Off Although it takes Arjuna a long stretch of time to charge up his Noble Phantasm, due to Arjuna breaking and remaking the world over and over, its space-time started to fall apart.Fate/Grand Order: Cosmos in the Lostbelt - Yuga Kshetra: Genesis Destruction Cycle, Section 17: The Flaw of Being "There" Since the world of the Indian Lostbelt gets leaner and leaner as more excess is shaved off with each yuga cycle, it requires a bit less Magical Energy to destroy it as the cycles go on.Fate/Grand Order: Cosmos in the Lostbelt - Yuga Kshetra: Genesis Destruction Cycle, Section 14: Those Who Laugh During the End of Yuga

Karna was able to momentarily endure this Noble Phantasm by activating the True Name of his armor, Kavacha and Kundala. By becoming the very radiance of the sun thanks to his nigh-indestructible armor being imbued with Surya's power, Karna was able to endure Arjuna’s destruction for 5 seconds. Rama was impressed he lasted as long as he did, and he said that was a feat akin to holding back all the waters of the ocean or catching a falling star with one’s bare hands. He states that there are a few heroes in all of history who could have withstood a cataclysm like that, even just for a few seconds. The combined efforts of Ganesha and Lakshmibai were also strong enough to endure Arjuna Alter's cataclysm for thousands of years. Thanks to the goddess inside her, Lakshmibai was able to use her Divine Core and her Noble Phantasm Nahi Doongi to constantly supply Ganesha with Magical Energy, who in turn used her Ganesha Vighneshvara to create a shell able to shut out everything from the outside world. To endure Mahāpralaya, Ganesha based her Noble Phantasm on the most impenetrable thing she knew about, an impenetrable domain made for the sole purpose of ignoring the outside world. This massive object known as God's Skyboulder is an alternate world that physically embodies the very concept of shutting oneself away. Although the God’s Skyboulder successfully endured Mahāpralaya for thousands of years, Ashiya Douman states that Arjuna Alter should be able to destroy it if he were to focus solely on it.Fate/Grand Order: Cosmos in the Lostbelt - Yuga Kshetra: Genesis Destruction Cycle, Section 18: Together With You, At the End of the Eternity Known as a Moment
As expected, when Arjuna Alter is summoned as a Servant of Chaldea, he is not able to wield the sword to its full extent. That said, if limited and condensed, the destruction it causes is equal to that of Pashupata and Arjuna seems to find its ease of use in that form to be sufficient.
