Essence ofAll For One

By consuming this colorless and hollow essence, you bring all abilities under the authority of your own ego.

• You are capable of stealing the quirks of others for yourself with but a single touch - that is, you're capable of stealing their 'individualities', their most iconic attributes and abilities. In return, you may also gift any of your quirks to another via physical contact, if you so choose.

• Discrete personality-based powers, generic cape superpowers, one-off mutant abilities, and their ilk will always count as "quirks". Within a wider context, other forms of distinguishing ability may also be subjugated to your command, such as a more static inherited bloodline or an ability to access a particular magic system.

• Transplanting a quirk by means of this essence never lessens it. Likewise, giving or taking a quirk by means of this essence never causes a donor or a recipient any direct damage; bodies, minds and souls will flawlessly adapt to fill in the gaps left behind stolen capabilities with lessened but healthy tissues, or integrate new capabilities without any risk of immune rejection or similar backlash.

• By dint of your absolute authority over quirks, you are always guaranteed to be their master, and not the other way around. Quirks in your possession may have unacceptable drawbacks to their use, or otherwise impose strange burdens, but you are categorically immune to any form of compulsion or mental influence bound up within your quirks, and you always remain in full control of the faculties they give you.

• There is no limit to the number of quirks you can possess at any one time, for they will interface harmoniously with each other in any eventuality short of gross morphological incompatibility - such as the combination of a quirk that transforms you into a living gravitational singularity with a quirk that renders you perfectly weightless. Even then, you may deactivate any quirks you don't want to use, shuffling them out for quirks you do want to engage.

• You may also use the aforementioned ability at any time, for any reason, to seal quirks away or retrieve them at will. Deactivated quirks are undetectable; you are treated for all intents and purposes as if you didn't have them, at least until you withdraw them from the slumber of your private 'storage' once again.

• When expressing multiple quirks simultaneously, strictly identical quirks will always 'overlap' with each other to no benefit, in much the same way that a swab of paint can't be mixed with itself to create something more. Similar but non-identical quirks may stack with each other, however - and especially so if their superficial similarities belie meaningful differences in form, function, or nature - creating a whole that's radically more than the sum of its parts.

• When giving quirks to others, you are capable of leaving shards of yourself within those boons if you so choose, rooting into the recipients of your generosity. These shards, though unconscious, will subtly influence their holders. At their weakest, they could simply render their hosts more agreeable to you; at their strongest, they could completely strip their hosts of autonomy and higher awareness, slaving them as vessels to your will.

• You are capable of targeting anyone who holds a shard of yourself in this way with any power you possess, regardless of distance or ordinary power vectors, as if they were directly by your side and vulnerable. You can use this ability to take quirks back, give orders, take a firmer hand, or punish disobedience as you so choose.

• Because of the aforementioned entanglement of your consciousness within your powers, anyone who succeeds in recreating your powers creates a full copy of yourself, latent within its new host as if it were a particularly independent shard. Such full copies of yourself may self-destruct if you choose, depriving their hosts of your powers and averting a dominance contest between two iterations of yourself, or they may progressively take their hosts over, infecting their hosts over time with your own personality, memories, and values.

• These shards will always take their hosts over if they're the only surviving copies of yourself, allowing any sufficiently functional copy of your powers to serve as a kind of phylactery.
