Kronium

Kronium (Kr) is a fictional semi-organic metallike element that makes the skeletal structure of the BFBs. It can adapt, transforms and evolve pretty quickly but stops the evolution when the BFB is near the age of 18 - 21. After that the body stays the same without any natural transformations. It however can be changed if BFB uses something that can cause mutations, transforming them even more.

Kronium can vary in types and have a different color based on these types:

Kr (Alpha) - The main and most common type of the Kronium. It has a metallic, steel color with not really bright shine to it. (Available to anyone.)

Kr (Beta) - Still common type of the Kronium. It has a copper or bronze color to it with a brighter shine to it. (Available to anyone.)

Kr (Gamma) - Uncommon type of the Kronium. It has a brass color to it, rarely being shiny. (Available to anyone.)

Kr (Delta) - Rare type of the Kronium. It has a shiny gold look to it and can vary in colors of the gold. (Only available if Hand of the Wealth used.)

Kr (Epsilon) - Super rare type of the Kronium. The BFBs with this type of the coloring are almost one in a million. It can change color based on the conditions or host preferences. Can not be gold or bone colored. (Only available if E-Element used.)

Kr (Omega) - Extreme rare type of the Kronium. It has bone like look but strong, durable and flexible as usual Kronium. (Only available if Necromancy Brew used.)
