A hidden power said to be inside every "Dark Bakugan". Linehalt was shown to have this power in episode 25. This power seems to be strong enough to destroy entire worlds or planets; however, it was stopped by Dragonoid Colossus. Linehalt described this as a curse placed on him and all the Bakugan of his kind. Since it has the word "Forbidden" in it, it's possible that Linehalt can use Forbidden Cards such as Chaos Ability X.
In Destiny Revealed, Linehalt finally understands what he should use his Forbidden Power for and uses it to heal the battle-damaged Neathia. His wings also gain an angel-like appearance, which is unusual for a Darkus Bakugan.
