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.
*Once you and you alone decide if your power is to pass on to another and have acted on it, you will begin to slowly weaken in everything but willpower, becoming nothing but a weak shadow of what you were before. Your memories will also stay with you, your brain able to retain the possibly infinite number of experiences you have had. The person who now has your power will also now find that there is an echo of yourself imprinted into their mind, allowing the echo to communicate, with the new holder of your power. This echo will never able to leave that entities' mind until the power passes on or the entity dies. This will also stack, allowing future carriers of your power to communicate with you even when your existence has long been forgotten in the infinite of the omniverse.
