Mecha Core!

"Third Prince! You are not allowed to be here! Leave immediately or else we-"

CRACKLE!

G-Drake's back fins powered up ominously and instantly generated a humongous amount of energy.

GRAAAHHHHHHH!!!

A chilling beam of yellow energy surged out of G-Drake's maw and smashed onto the third blue dragon that had only appeared a mere second earlier.

BAMSPLECHHH!

The energy beam pierced through whatever strange defensive barrier that the blue dragons had and vaporized an entire chunk of the third dragon's chest!

G-Drake was already a dragon of royal bloodline, and boasted a vastly more powerful dragon breath than non royal dragons. Even if he was but a little dragonling, his dragon breath was already extremely potent.

Add that to the fact that I had given him a biomech mod that enhanced his attack by a serious amount, it was no surprise that the third personal guard was felled with just one dragon breath attack!
