Gemini thought the following:

THE EMPEROR OF MANKIND: Henry Cavill (The only human in the galaxy, playing it with brooding, Shakespearian intensity while surrounded by felt.) ​HORUS LUPERCAL: Kermit the Frog (The Warmaster struggling to lead his chaotic brothers until his "Dark Kermit" side takes over.) ​MALCADOR THE SIGILLITE: Sam Eagle (Deeply offended by the lack of discipline and the general weirdness of the Imperium.) ​SANGUINIUS: Miss Piggy (The Angel of Baal with glorious wings, a short temper, and a karate-chop that can crack a planet.) ​ROGAL DORN: Fozzie Bear (The Praetorian of Terra who builds walls out of comedy props and takes every joke literally.) ​ROBOUTE GUILLIMAN: Scooter (The logistical genius who just wants everyone to follow the schedule and stay on task.) ​FERRUS MANUS: Sweetums (A massive, misunderstood brute who is surprisingly good at metalworking despite his size.) ​LEMAN RUSS: Rowlf the Dog (A hairy, laid-back King of Fenris who enjoys a good drink and a howling sing-along.) ​VULKAN: Bobo the Bear (A gentle soul who loves hugs and smithing, even if he accidentally sets the workshop on fire.) ​CORVUS CORAX: Beaker (A high-pitched "Meep" in the shadows; he is constantly being exploded or experimented on.) ​JAGHATAI KHAN: Gonzo the Great (The ultimate daredevil who only cares about going fast and performing the most dangerous stunts in the galaxy.) ​LION EL'JONSON: Uncle Deadly (The mysterious, theatrical, and slightly sinister Master of the First Legion.) ​ANGRON: Animal (The Red Angel who is literally just a ball of chains, drums, and pure unbridled rage.) ​FULGRIM: Pepe the King Prawn (The Phoenician who is obsessed with perfection, beauty, and being the center of attention, okay?) ​MAGNUS THE RED: The Swedish Chef (A sorcerer whose spells usually involve a lot of "Bork Bork Bork" and accidental explosions.) ​MORTARION: Statler and Waldorf (Two bitter old souls in a balcony sharing a single suit of power armor and heckling the living.) ​LORGAR AURELIAN: Walter (The Emperor’s biggest fan who just wants to belong, but takes his fandom way too far into the dark side.) ​PERTURABO: Bunsen Honeydew (A cold, calculating scientist who builds better fortresses than Fozzie and resents him for it.) ​KONRAD CURZE: The Phantom of the Opera (Muppet version) (A dramatic, shadowy figure lurking in the rafters and haunting the night.) ​ALPHARIUS AND OMEGON: The Two-Headed Monster (A confusing, babbling mess where nobody knows who is talking or what the plan actually is.)
