Memetic Mutation: Largely averted, though many are imported from this very wiki. Notably, referring at something (well, everything) as being IN SPACE.
Galaxy Baade
Magnificent Bastard: Konstantine Ivanov, once Baade's resident evil doer. He managed to avoid punishment for murder so many times that even when he was caught he managed to play galactic society as a whole and get away with little more than a slap on the wrist.
His replacement, Arthfael Daunt, does it with even more style.
Galaxy Draco
Magnificent Bastard: Subverted by Overlord Jago Ragnarok. His spy in the Emperor's Court was exposed, his attempt to spread the plague across the galaxy failed to make it off a single planet, and his plague-bomb that was supposed to infect the Court of Nobles malfunctioned. He was so incompetent that he even escaped blame (posthumously) for the actual murders that took place at the Council.
Galaxy Eridanus
Moment of Awesome: Oscar going into the Void. Alone. With no training. To rescue his sister. Because the alternative was letting his wife and brother-in-law go.
Magnificent Bastard: Michael Sheridan of Gemini's backstory must have been, if he was able to unite and preserve an Empire around neighbors like these.
Galaxy Avalon
Magnificent Bastard: William Cartheon, once Emperor of Avalon, as well as Osborn Barinthus, both displayed traits of magnificent bastardry.
Galaxy Fornux
Funny Moments: "House Esposito, its Dynasty members, and all off spring of the house shall henceforth and for all time carry the official title of "The Dastardly." Imperial records shall be amended to read "The Dastardly House Esposito" Nobles of the galaxy should address members of the Di Esposito family with full title. "The Dastardly Count Giacomo Esposito."
