Essence of the Involate Self:
Drinking this essence confers you the blessing of inviolability of the body, mind, and soul:
You no longer need to eat, drink, breathe, produce human waste, or sleep, and are immune to the harmful effects of radiation alongside extreme environments ranging from the bottom of the ocean to the vacuum of space.
Total immunity to all forms of poison, sickness, or disease, mundane or otherwise. Any existing ailments of a physical, mental, or spiritual nature that plague you will be completely cured upon drinking this essence.
You are biologically immortal and utterly tireless, possessing unlimited stamina - you will be aged/reverted to your physical prime, but no longer age further.
Infinite willpower to keep going through any amount of hardship; even bloody and broken you will not stop, and you will forevermore be protected from the effects of despair, boredom, ennui, etc., that will make living forever a pain in the ass.
Your freedom is also inviolate, protecting you from being imprisoned, copied, incapacitated, trapped, bound, sealed, etc., against your will, automatically freeing you from such situations and teleporting you to the nearest safe location.
You are completely immune to any attempt to forcefully change, control, copy, or manipulate your body, mind, and soul against your will in any fashion, no matter what method is attempted or used. Those who use supernaturally boosted persuasion are equally stymied, being forced to rely on simple mundane arguments against you as anything beyond that flatly fails to work. You are also immune to memetic effects or the maddening effects of eldritch beings or phenomena.
Your soul cannot be targeted as a vector of attack - the only thing you are still vulnerable to will be actual physical violence if such things can cause damage to you.
No Oracles or any other form of precognition can account for you, ever. Any predictions that are made will be made without taking you into account, and if seeking you out directly, all they get is static. In addition, you are not bound by fate anymore; your destiny is only what you make of it. This extends to the point that people and events that are deemed unstoppable or even unkillable, just because they are destined to, can be killed by you permanently.
You are also immune to reality-warping shenanigans, such as being caught in time paradoxes, time stops, not existing due to someone killing your mother when she's pregnant with you, etc. - your very existence is inviolate.
Note: You can still be injured or killed through direct physical damage if such things are capable of damaging you; all this Essence does is prevent your body, mind, and soul from being affected by other forces without your consent.
Essence of Plus Ultra:
In the darkest of places, the most desperate of times. When all is lost, and there is no hope. This essence will be the one to bring light to even the most hopeless of causes.
By drinking this essence, you gain the knowledge and ability that made All Might, Superman and Captain America the greats of their time. You do not gain their powers, but rather, you will naturally begin to understand how they inspire hope, teamwork and positivity, your mind becoming a weapon that will pierce all evil and bring back even the most broken of people. And thus, know now how to change people for the better.
You have a charisma that is unrivalled, knowing exactly what to say and when to say it. Instil teamwork and cooperation where even the worst of rivals can work together. Your very presence makes people have hope and makes them never give up, even in the most desperate of times against the foes that they know cannot be defeated.
You will find is as easy as breathing to recruit people to your cause, to your ideas as you bring purpose and hope to them wherever you go.
Your presence encourages people to grow past their damaged minds and spirits, even if they are only interacting with you for a moment, making them slowly heal, and even if they try to spiral back into the darkness that you drew them from, their very memory of you will stop them.
With your presence, you will instil awe and fear to all enemies you face, even if they are a galaxy-spanning hive mind of bugs, a cold machine, or anything else inhuman. They will know fear.
Your will is infinite and unbreakable. You can undergo all suffering, all pain, and all difficulty. Even when your body should be in the greatest of damage, undergoing the most terrible of events, and facing the worst of foes, your mind will be untouched and unbroken, allowing you to continue of without even blinking. Additionally, your will allows you to combat any changes that will affect your mind, making your immune to even those that can manipulate your brain through biological manipulation. Your mind is your own and nothing will change it. This also grants the boon to hold onto skills, abilities, powers and whatever else that is inherently you, no one can take what is your own, nor suppress nor act without your consent.
No matter the scenario, no matter the foe, you are infinite in will, you will always continue moving forward. Nothing will break you. Nothing
You can continue on no matter how defeated, how damaged, how broken your body is. Your spirit will continue to move and as long as you are outright dealt a fatal blow, can make the body continue to act.
Additionally, this essence will always fill you with a sense of purpose. While this can be to a hero, it can be something similar like wanting to teach people or to help those less fortunate without a cape at your back like a police officer or nurse. Whatever it is, it acts as a foundation and centre for your sense of self and a wellspring of drive and motivation.
With this purpose, you can use it to ignite the fuel that is your existence and dump all your power, all your stamina, all your magic, everything that makes up you that won't outright kill or maim you if it is used for fuel, into a single moment. This moment becomes an action or an attack that when unleashed can break even the most powerful of foes, even when you are at death's door and you are beginning to weaken, this purpose-filled action will be greater than anything that you could do even at your best.
If you use your purpose initially before your body is nearly broken by the obstacle(s) you are about to face, while you are still strong in body, mind and soul, the action or attack would be greater than ever possible naturally. But afterwards, no matter how you were before using your purpose to fuel your abilities, it will be a miracle if you could stand. No matter what abilities, powers or miracles you have, you will be exhausted and out for a significant amount of time.
This ability will not give you the abilities of a hero, but the mind and soul that is needed to be the greatest. And even if you should fall, your memory will drive the people you meet, the people you inspired and given hope, to be heroes and to do much greatness that is not even though possible.
And yes, should you find yourself satisfied with the state of the existence around you and want to pass on to the afterlife, or generally wish to stop being the immortal super god that you are. Whatever the reason, you can pass all your powers, all your strength, all your essences on to another, everything that wasn't learnt being imprinted onto a single entity chosen by you. How you pass it on, will be up to you to decide, a pat of the back, a magical fruit, having the unfortunate individual eat a strand of your own hair, whatever you think would be necessary.
Your powers and DNA cannot be stolen, deleted, copied or anything like that, you will have constant protection against negative effects, in case something unexpected happens, you will be randomly teleported, your powers will return, eventually, they always return.
Essence of the Blank:
By taking this essence, you gain but one benefit: Your potential becomes limitless. You can learn any discipline or skill set, even if you aren't capable of it, without forgetting it and practicing it into mastery, no matter how much you learn. Any abilities you have from other Essences will increase where possible and develop in ways beyond their initial purposes.
Essence of My Hero Academia:
You may remake your body however you want.
You now have complete control over your body and any powers you have. This means you don't have to worry about accidentally tearing the door handle off or punching a hole straight through someone. This works subconsciously, so you won't have to actively try to control yourself. You can even control your sense of pain and discomfort.
You will receive a quirk. This can be any quirk from MHA or it can instead be a Quirk of your own design.
Optionally, you may choose to receive a Quirk that is essentially a merged version of One for All and All for One.
Like All for One, you are able to steal quirks, though you can do it through touch instead of through the hole All For One has in the middle of his palms.
But unlike All for One, you are able to duplicate any quirk you have, and gift away copies to other. You can also merge copies of quirks you have to create a new quirk. Which you can then copy as well.
People that already have quirks don't have to fear rapid aging or any other consequences from having more than one quirk, and neither do you, as your quirk makes it so that the quirks harmonizes with the body in such away as to prevent causing problems and negative effects like shortening their or your lifespan or putting a strain on their or your body.
You can also improve any quirks you own, similar to how the One For All has increased the power of the quirks the former wielders had. This is done via the energy stockpiled in One For All. You don't necessarily have to increase the power of the quirks, and can instead change how they work and improve them in other ways.
The energy stockpiled in One For All will never go below the amount All Might has access to, allowing you to enhance any quirk you have and get over time without having to fear running out of energy. As a consequence of this however, your quirk will never stockpile any energy beyond All Mights level either.
Like with the original One For All, you can use your quirk to significantly enhance all of your physical abilities to a superhuman level. This results in unbelievable levels of strength, speed, agility, and durability. You have the same level of power as Prime All Might. And like All Might, you are able to wield it without any recoil, as your body has already adapted to it.
Like with the original All For One, If you steal even if the user holds Mutant-type Quirks, the subsequent features do not permanently manifest on your body, and you can instead summon the mutant features at will.
Your quirks cannot be stolen nor cloned.
You may choose up to nine quirks to already have in your possession.
This Quirk works for any similar power, like mutant powers, perks and anything else you can reasonably think it should work on.
