Aun Aun no Mi

The Aun Aun no Mi (Kanji: 阿吽阿吽の実; English: Om Om Fruit) is a Logia-type Devil Fruit which endows its consumer with the ability to materialize, manipulate, and or metamorphose into brahman. Thus turning its consumer into a Baramon Ningen (Kanji: 婆羅門人間; English: Brahman Human). It was eaten by BLANK.

A Definition of Brahman
In Hinduism, brahman does not change as it causes all changes. Thus, in terms of chemistry, brahman is best understood as the ultimate catalyst. A catalyst is a substance that affects a chemical reaction without being affected by the chemical reaction, much like how Hinduism's brahman affects all changes without being changed itself. So the brahman that is generated by the Aun Aun no Mi is a universal catalyst. It is able to initiate any sort of chemical reaction without being affected by the chemical reaction itself.

Advantages

 * Brahman is able to catalyze anything, regardless of whether it's physical or spiritual.
 * Brahamn is unable to be affected by anything. So the consumer is invulnerable to non-haki attacks. This includes attacks against the consumer's soul.
 * Brahman is unable to be heard, seen, smelled, tasted, or touched. As a result, the consumer is able to become imperceptible by metamorphosing his- or herself into brahman. In addition, because brahman is as spiritually unalterable as it is physically unalterable, kenbunshoku haki is useless against the consumer.

Disadvantages

 * The brahman has no properties of its own. It's forceless and massless, so one is unable to harm anyone or anything by hitting them with brahman.
 * Using brahman as a catalyst will reveal the location of the brahman by virute of the byproducts of the catalysis. So the consumer is not imperceptible while the consumer is using the brahman to catalyze an entity.
 * The consumer is MORE susceptible to haki than the consumers of other logia. For not only does haki allow one to damage the consumer, but it also allows one to resist being catalyzed by the consumer's brahman as well. With this in mind, a powerful user of haki will be able to use busoshoku to prevent his- or herself from being catalyze and then use kenbunshoku respond to whatever the consumer attempts to catalyze into a weaon rather than the consumer his- or herself.
