Now THAT is terrifying. At least when large, the breathing and movement is spread out across a LOT of distance, and ridiculous amount of water dampens the impact. But when small, that concentration would be like hundreds of nukes detonated simultaneously from the same origin point,

It'd be a Black Winter scenario. The Multiverse may be able to survive its presence, but not attacks - the Scarlett King is supposedly of a level of power equal to, if not, significantly greater than even the One Above All. It's basically an Outer God.

sorry this is so long, I have a real problem with short and concise sentences

EXACTLY! It's one of the main reasons I don't dabble in religion - if police forces, investigators, reporters and many others can be mistaken for decades about a murder or various other crimes and significant things, how could I possibly believe in a text that's well over a thousand years old, has been translated numerous times, rewritten by human hands, and passed down through dozens of generations - more than enough times for people to: misunderstand, miss-traslate, make writing mistakes - Heck, even fabricate or remove stuff for monarchs and church leaders centuries ago to better control the people and gain other benefits from changing it, or even the writers making mistakes - like how I believe a certain story, I don't remember it in full, but they were said to have been given a message from God, who appeared as a face in a burning bush. I feel that one could potentially have just been something like a weed bush or something, and the guy got high - if there are people today proclaiming they are pregnant and the child is Jesus, then I don't seen why similar things couldn't have happened back then. it's all too ambiguous for my taste - humans are too untrustworthy for me to just take the words of a mass-produced book at face value, especially with how, even now, machine translation (MTL) can barely even translate, so back then, translators would likely be unable to be too accurate.

I read like a chapter or two and forgot it all, but I think the guy had a lot of skills, so a play on the word skill and 'million, billion, or trillion' -aire? Or maybe it doesn't translate well into English

For those who don't know, in the SCP universe, it is discovered that after death, you remain conscious and feeling forever. Those cremated feel being burned, those buried feel their insides rotting and being eaten away by worms, rats, and other things, Even when you are just scattereed dust, you still feel it.

It has been sent to another dimension, and literally erased from reality and came back. I doubt that would work.

I mean, to be fair, the scaling of power doesn't mean that against one another, they'd always win - I'm sure you can find many beings that are weaker that can punch above their weight class, after all - immunity to reality warping wouldn't make you any stronger against the average person, but reality warping on the other hand makes you much stronger. For example, a reality bender of a level where they can change a building could probably beat Buu Saga Goku with ease, despite the fact he was probably Galaxy-level then due to the nature of their power, and how Morro from after DBS's TOP was FAR weaker than even Buu Saga Goku when he was first introduced, but quickly grew to match even MUI Goku, or how someone like SCP-682 the Hard To Destroy Reptile / Immortal Lizard isn't particularly strong and can be beaten by high-caliber guns and explosives, and even with just the regeneration or adaptation it'd be powerful, but due to the adaption's temporary nature, it can be killed without much trouble, and the regeneration can be overcome with certain extreme methods, its just that together the thing becomes a true force of nature that, if not for how temporary the adaptions are, would have been impossible to contain and nearly unbeatable.

I don't know much of anything about her, but if you mean in terms of using raw destructive might to reduce it to nothing, then it wouldn't be the best idea - a lack of control could lead to her accidentally letting some of the energy (namely from the sun's explosion or any possible counterattack) reach and destroy the earth, even an amount as small as 1 / a trillion left over could be enough to reach earth and cause damage greater than a solar flare

What would you do, argue with the guy working for what is at least a multiversal organisation with potentially the power to erase you with but a thought?

Soooo.......Something like Joker dying from Harley? Or dying as a result of his own joke?

His Eldritch wife from a past life:

It's Harley, the publicity would probably be more of an encouragement

Cognito hazard has been a term since quite a while before the SCP foundation, its just that it wasn't as well known because of how few things you'd use it for, so the SCP foundation popularised it
