Dear Galvatron, what is your personal favorite energon beverage? (I bring it up because Vector Prime was asked this a while back, and he explained the recipe for his "Famous Original Bottle-Buster Hyperbeer." P.S. Have you ever tried it?)
As befits the true emperor of destruction, I insist on the finest vintages of energon wine; the purest energon, filtered through circuit boards grown from substrate-vines of the highest pedigree, where they pick up traces of the rarest of metals—the tang of rhodium, the sweetness of iridium, and even the piquant heat of astatine. Though Brushguard's talents were best suited to the creation of deadly toxins and entangling creeper bombs, he also carefully selected the vines that were grown in the personal chipyard of Decepticon High Command, which was surely the finest on all of Cybertron!
Of course, while such wine will suffice to quench my thirst, you asked of my personal favorite. For that, there can be but one answer: sanguis fulgur, the favored drink of the old warrior-kings of Kaon. It is by nature a rare delicacy, as to make it, a fine energon wine must be fortified with the innermost energon of a hated nemesis who has been vanquished in battle. It is then sealed with a cube of highly radioactive material—in my experience, nihonium serves best—in a barrel made from depleted uranium, and then left to age over two thousand years. This irradiation, coupled with the power of innermost energon and the knowledge that it contains within it the lifeblood of a truly worthy foe, makes drinking sanguis fulgur a truly unparalleled experience.
Sadly, I finished my last bottle—made after I slew Sentinel Prime over the Straits of Yuss—many centuries ago. Some day, I shall defeat Optimus in glorious combat and have an even greater batch brewed from his fuel, but until then... hrm. It seems Vector left a bottle of his hyperbeer in his personal stores here. Perhaps I shall enjoy a quart, to toast my victory over that old fool!
