[Worthless]. The power which could invalidate special abilities

with Issei being the one exception because the power Worthlessness  it is rendered useless becuse the power Penetrate

and this is a good opportunity to see just how powerful Diabolos Dragon God is in its weakend state

just to be clear Diehauser [Worthless] isnt the same as Rizevim Livan Lucifer [Sacred Gear Canceller] Which possessed a unique ability which could nullify almost all Sacred Gear abilities and Sacred Gear-enchanted powers just by touch. However, it was incapable of nullifying Ddraig's Penetrate ability. Also, as powerful it was, the Sacred Gear Canceller had a limit, albeit a very high limit, to the amount of power it can nullify. This was shown when Rizevim's Sacred Gear Canceller was overpowered by Issei's Diabolos Dragon.
