Crystals are objects in Bomberman Blast.
Description[]
They are 4 colored crystals that were found by the scientists in the ruins. As soon as the Mii scientists collected them and were heading to their ship, they suddenly disappeared along with the crystals in a warp hole, and each crystal headed to their respective ruins, acting as their guardian, and each are holding one of the scientists captive. Each Crystal has the power to absorb the energy of the Mii scientist it held captive, and turns into a giant monster.
In addition, there is a 5th crystal, the Nova Crystal, that seems to be the root of the problem, and the leading entity. At some point, after the first phase of its fight with White Bomber, the Nova Crystal merged with the 4 other ones into Nova Arc.
