KOF Revisions

KOF's multi-continental status all hinges on a single thing: the Zero Cannon.
The Zero Cannon, going off of the official description, is a massive satellite laser outfitted with the same technology found within Krizalid's battle armor, which retrieves data from fighters and boosts the power output of whatever it's attached to.

The Zero Cannon is in possession of the Clone Zero, and his goal is to destroy the organization known as NESTS so he can conquer the world.
Now, the claims of Multi-Continental KOF are based around the Zero Cannon supposedly being capable of wiping out the entire surface of the earth-
But there's a big issue.
This is never backed up by anything concrete, canon or otherwise.
Furthermore, all of this stems from a single line of dialogue in the KOF 2000 endings by Clone Zero:

"Disintegrate in the light of a brand, new world"
That's literally it.
While are shown that the beam is capable of leveling a city, Southtown specifically, it was never established that it would be capable of wiping out the entire surface of the earth.

To add even more dubiousness to such a claim? Clone Zero specifically Southtown because that was where he believed the NESTS' base was stationed. And when he goes to use the weapon again, it is a desperate last-ditch effort to kill the heroes alongside him.
And to really prove how wrong the claim is:
The cannon hits the ground canonically and non-canonically when shot a second time and it does not destroy the entire surface of the world.
Besides the scene there with Kula's ending where it clearly hits the ground and does not actually kill everything-

Kim's ending gives a far clearer interpretation and the beam fails to do its supposed purpose.
This leaves the cast as Large Island Level due to being superior to Verse's feat of that caliber.

The Relativistic side of Proto's calc still looks fine and doesn't rely on the statement, so it can stay.
