Assuming the minimum amount needed is acceptable.
If you think it's above the minimum you're free to try and prove it.
Again, it's weird as shit that Sheldon keeps trying to make the K-T Extinction Event ORT's cap rather than the floor because again there are many reasons why in comparison to PHH where ORT's crash landing was nowhere near as savage, did so much damage the Malla got the Dinosaurs to safety in an underground cavern and reinforced Pangaea in the process.
A) ORT didn't bother to protect itself at all because it knew it would regenerate later.
B) ORT's fall basically fucked up the Planet's surface beyond repair even to the current day(Which did not happen with the K-T Extinction Event for obvious reasons) which would mean it's impact was even more devastating than the K-T Event by magnitudes.
Easiest reasons in the world to bring up... people only begin to bring up B and not to it's fullest potential.
Why is it inconsistent with surrounding feats and statements? Just because ORT regenerated faster when it was fighting Chaldea?
Because ORT withstood shit that would make the K-T Event look like a firecracker, that's PRECISELY the problem here...
Like it's long ridiculous to pretend that Servants of all kinds is weak as shit because of the same retarded principles that don't even work for most shonen have been stuck onto it but it begins to seriously make no sense when ORT's weakest parts was smashed to shit by thousands of Gugulanna's legs by a charged up Ereshkigal Alter... and it ultimately didn't and wouldn't have mattered anyway. That it could lose an organ from the MEoDP and not only regen it, but make it stronger against the very damn thing that killed the organ. That the characters got buffed up by Ereshkigal Alter's Underworld buff which previously allowed them to actually hurt Tiamat to be able to chip at ORT's outer shell... suddenly means it's CAP has to be the K-T Meteor... despite Quetzalcoatl's NP BEING THE K-T METEOR and Kukulkan while alive can do that level of power effortlessly... and it didn't work.
There is a world of difference between "fall at terminal velocity" and "impact a planet at interplanetary speeds".
From my perspective, 100 teratons is already plenty impressive, more than enough to put ORT in the very top tier of the Nasuverse.
"See? I'm being fair to the Nasuverse, no one is capable of generating 100 Teratons of power... just ignore U-Olga Marie, the Beasts, Lostbelt Zeus and the Servants capable of rivaling them which is explicitly stated that plenty DO".
Let's ignore Quetzalcoatl can handle putting the equivalent of a Star inside of her and become the K-T Event, Ozymandias Dendra Light Bulb being able to generate heat on the level of a solar flare, Rhongomyniad being able to overpower Animus Animusphere, Durandal being able to block a Planetary laser... TWICE and many, many more things like a weapon on par with Rhongomyniad being blocked by Heracles despite suffering a few of it's demerits because willpower.
He does not "burrow" down to the bottom layer. Mictlan was created by Malla, and it is hollow by default. ORT would only need to penetrate the "cap" and then it's a straight fall through empty air all the way to the bottom.
Given that Malla hollowed out Mictlan, the crust covering the underworld is unlikely to be particularly thick. Even the Chicxulub meteor IRL was able to penetrate 30 kilometers of crust, and that was with a mantle beneath the crust. If it was just the crust with no supporting mantle beneath, a K-T asteroid could definitely pierce through the entire crust.
Ah yeah, The Underworld's crust must not be all that thick despite the fact it absolutely would considering the surface of the Planet is literally fucked all over with lava, endless smoke and no goddamned sun due to all of that smoke...
Seriously, this is extremely stupid considering the fact that again, Mictlan does not act like the equivalent of a small ass tube but more of an Space Colony Sector.
I know, but even while it's outside ORT and not providing energy, it still has a link to it. This link is what makes ORT regenerate faster, because it's prompting ORT to regenerate.
This is literally the anti-thesis of everything that is ever shown about Kukulcan, ORT's heart and ORT...
Kukulcan was literally beckoned by ORT to become whole again and had to fight off it's influence. ORT went after her because while it COULD regenerate a new heart, it's more machine-like nature prioritized getting it's heart because as it's just more efficient. And of ORT still had a link with Kukulcan to "regenerate faster", then it wouldn't have died and needed the Throne of Heroes to come back and just reformed AROUND HER.
Sheldon literally cannot fathom that the reason ORT is even active is due to it's own body and being allowing it to still be alive without a heart and using 2 Substitutes(The Tree of Emptiness and U-Olga's Heart) and even then would have woke up eventually as the Malla forced it to sleep for millions of years.
As a matter of fact, I believe that the reason ORT regenerates faster when fighting Chaldea is because it doesn't have a heart. Without a heart, it was forced to make all of its cells generate their own independent energy.
As we know, ORT needs power to regenerate. Thus, if all his cells have their own power output, even if the total output is still lower than the heart, the regen can be faster because he can regen from any part of his body.
Meanwhile, he presumably lacked this Massively Distributed Power Grid back in the Cretaceous when he first crashed.
...That is literally false as shit...
Nothing has ever shown that ORT "needs power" to regenerate, it's actually the opposite in that without it's main source of the power it has within itself(i.e. It's Heart), it would ultimately power down for awhile before immediately waking the fuck back up and just creating the new organ and start over. That's the entire reason the Malla had to force ORT to sleep despite Camazotz taking away it's heart and the Malla grabbing it as otherwise ORT would have just regened and it and Camazotz would have fought for all of eternity. Tezcatlipoca literally states that ORT "would wake up eventually" regardless of his and Daybit's plan, all they are doing is expediting the process.
