BakuCore (Battle Planet)
A BakuCore is a metal, hexagonal shaped tile that empowers Bakugan and allow them to transform from closed to open ball form in the Bakugan Battle Planet game. It is the replacement for the metal Gate Cards from the Legacy Series. BakuCores are only to be used with Battle Planet Bakugan (which are 36mm sized) and it is possible to pick up two BakuCores at once. Additionally, you are allowed to mark the underside of a BakuCore with markings/stickers as long as the text isn't covered.
