 * Audible Gasp*

What if the power source for the Boosted Gear Diabolos isn't another dragon (like the case with Albion, Ddraig, Fafnir, Vritra, etc.), but Ex Gremory himself?

The only reason Euclid was able to make a Boosted Gear as close to the original as he did was because he studied Ddraig's aura from Issei's (original) body. He replicated Ddraig's abilities, but since he didn't have the genuine article's soul, it was like making a "hollow, plastic copy of a marble sculpture." So he used the souls of other dragons to "fill in" the hollow replica.

But Ex Gremory, as the son of Issei, has the body & aura of a Dragon.


 * Body from Great Red.


 * Aura from Ddraig and Ophis (Since DxD G mode combines Ddraig's and Ophis' powers).

So the Boosted Gear Diabolos is just like Euclid's Boosted Gear Replica, but instead of using/sacrificing dragons to use it, Ex just needs to use his own Dragon Power to use it.
