The Explosive Core (ボムのもと, Bomb Base, in Japan) is an item that appears in Bomberman Quest and Bomberman Jetters: Densetsu no Bomberman. It can be combined with other bomb elements in the Bomb Workshop in order to make a new type of bomb. There are a total of nine in the entire game.
In Bomberman Quest, Explosive Cores can only be used once. In Bomberman Jetters: Densetsu no Bomberman, there is only one Explosive Core, and it may be fused with other synthetic materials multiple times.
