The Kakugane (核鉄, Japanese "Nuclear Iron") are alchemical devices used by Alchemic Warriors to form their Buso Renkin, they are one of only two known forms of alchemy (alongside the Homunculi) which are capable of functioning successful.
Overview[]
Each and every Kakugane has the same basic appearance, being roughly hand-sized, hexagonal medallions with an hexagon-shaped indent at the center of both sides.
Within these indents, the classic alchemical symbol for Amalgam is inscribed with a Roman numeral value, representing the Kakugane's serial number, written directly below it.
Kakugane were developed in the process of creating the Philosopher's Stone, the ultimate goal of Alchemist the world over, as well as a possible counter against the Homunculi.
Prior to the start of the series, there are 100 Kakugane (labelled "I" to "C"), the initial three being turned into Black Kakugane with the second later being remade into a White Kakugane. After the "Victor Incident", the Kakugane were scattered around the world. Currently, there are 29 known Kakugane that are used in Japan, including the 3 White Kakugane.
Powers & Abilities[]
Buso Renkin Creation: The primary use of a Kakugane is the creation of a "Buso Renkin", a powerful weapon or object created based on the user's fighting instinct, opening up and morphing into a new form based on their unique skills and fighting style. Besides there individual power, Buso Renkin are the only known weapons that are capable of destroying Homunculi.
- Double Buso Renkin: Although rare, certain Alchemic Warriors have the ability to use two Kakugane at once to create a "Double Buso Renkin", allowing them to produce a near identical copy of their primary Buso Renkin. However, using a Double Buso Renkin requires a lot of energy and can become unstable. So far, no Alchemic Warrior in the series has been shown to use more then two Kakugane.
Enhanced Durability: The Kakugane are highly durable as they have been shown to be able to block other Buso Renkin even while deactivated. However, a Kakugane is not invincible and can be damaged or even destroyed with enough force.
Regenerative Healing Factor: The Kakugane can self regenerate from damage and will slowly heal whoever is holding one, the healing process can be quickened by holding more than one Kakugane. Its regenerative properties are so great that one can also function as a replacement heart allowing the user to function even when it has transformed into a Buso Renkin. It is notable that the only Kakugane used for this purpose in the series have been Black Kakugane.
Variations[]
Black Kakugane: These are powerful, but unstable, variations of the Kakugane. When implanted into a persons body the person will undergo Victorization, a transformation named after Victor Powered. As well as this they can create a Buso Renkin, like all Kakugane, however a Buso Renkin created by the Black Kakugane are often much stronger.
White Kakugane: Developed by Alexandria Powered, a White Kakugane is the exact opposite of a Black Kakugane. It holds the ability to nullify a Black Kakugane's power, restoring a person with a Black Kakugane back to normal.
