Earth Wind and Fire

Earth Wind and Fire (アース・ウインド・アンド・ファイヤー) is the name of Mikitaka Hazekura's power appearing in Diamond Is Unbreakable. It is currently unknown if Earth Wind and Fire is a Stand or an alien ability due to the mysterious origins surrounding its user Mikitaka.

Appearance/Personality
Like a few other Stands, Earth Wind and Fire doesn't actually possess a physical form: instead, it is bound to its user's body. It has no personality, as it is just an extension of Mikitaka's very body.

Mikitaka's alien identity draws speculation that it may not be a Stand, but rather an evidence of Mikitaka's alien nature, making Earth Wind and Fire a kind of strange alien power rather than a Stand. However, evidences supporting each theory leaves even more doubt about its origin.

Abilities
Transformation: Mikitaka's ability allows him to transform into almost anything. He seems to be able to combine his strength with those of other people: when he turned into sneakers for Josuke to wear, he notes that their strength combined is what made them able to move away so fast. Although he can transform into almost any object, he is unable to transform into complex items like machines or something that requires more strength than his own to operate (i.e. dynamite) and copy the appearances of other people. This is because all "earthlings" look the same to him.

Regeneration: Earth Wind and Fire seems to possess regeneration, as Mikitaka transforms part of his hands into ice-creams and separates them from his body, but nothing is missing from his hands later.

Stand Blindness: The strongest hint that Mikitaka said the truth about him being an alien and not a Stand user is the fact that Earth Wind and Fire does not grant its user the ability to see other Stands, a trait that all other Stand users share. Some fans speculate he lacks this ability because he was only half pierced by the Arrow. However, it is still unclear whether it was the Arrow that granted him a Stand ability or whether he inherently had this ability from his "alien heritage".

Trivia

 * Hirohiko Araki mistakenly used the name "Earth Wind and Fire" again in Stone Ocean for the name of Viviano Westwood's Stand when the chapter was published in Weekly Shonen Jump (the name was written slightly different in Japanese). For the tankōbon release, this Stand was renamed "Planet Waves".
