Kwamis

Kwami are sprite-like creatures that help particular people with Miraculouses transform into superheroes and stop akumas.

Appearance
Generally, kwami are small with large heads and tiny bodies. Whatever superhero they help transform someone into affects their appearances, like Tikki being red with black spots and antennae like a ladybug and Plagg being black with green eyes, cat ears, and a tail like a cat.

Abilities
Kwami inhabit pieces of miraculous jewelry (like earrings or a ring) in order to give the person wearing them the ability to transform into superheroes. However, kwami can only keep the transformation for so long. When they lose enough energy used by the wearer, usually after the wearer utilizes their special power, the wearer reverts back into their normal form, typically after five minutes. To regain power, kwami need to refuel by eating food.

List of kwami

 * Tikki (inhabits Marinette's earrings for her to become Ladybug)
 * Plagg (inhabits Adrien's ring for him to transform into Cat Noir)
 * Butterfly kwami (appears to inhabit the Butterfly Miraculous)
 * Green kwami with an antenna on its head (appears to inhabit the Green Miraculous)

Trivia

 * At least according to the artistry of the box and their Egyptian incarnations, it would appear that Ladybug and Chat Noir have always worked together. The Ying-Yang symbol is is suggestive that a balance between the two powers is required for harmony.
 * A kwami is a "quantic kami." In Japanese, kami means "God."
 * According to Thomas Astruc, the name of every kwami has to be a short name with a double letter in it.
 * Only two kwami have been seen in the show so far, although two unnamed kwami (butterfly kwami and green kwami) appear in the theme song.
 * Also, in the theme song, the four kwami fly into a chest box with seven sections, each section including the piece of jewelry that the kwami is connected to. Three sections that kwami do not appear for in the theme song are the Blue Miraculous, the Orange Miraculous, and the Yellow Miraculous.
 * The box appears to be patterned after an East-Asian influence, as evidenced by the octagonal construction, the flower-patterned inlay, and the stylized, red relief. It's currently unknown why this is.
 * The Miraculous jewelry that the butterfly kwami inhabits looks identical to the bow that Hawk Moth wears, likely meaning he has possession of it.
 * If Volpina is a Miraculous holder, then a fox-themed kwami will likely exist.
