The long-awaited answers to October's trivia quiz, whose theme was "random questions that don't have a theme".
1. When did the Legionnaires stand in line with the Doom Patrol, Plastic Man, and Sargon the Sorcerer?
2. Who were the two Martians shown at Bouncing Boy and Duo Damsel's wedding?
J'onn J'onzz and Tars Tarkis. The Martian Manhunter's appearance here led to his appearances in the v4-era stories, while nobody was really quite sure what to do with Tars Tarkis (from the John Carter, Warlord of Mars series by
Robert E. HowardEdgar Rice Burroughs).
3. What does C.O.M.P.U.T.O. stand for?
Cyber-cerebral Overlapping Multiprocessor Universal Transceiver-Operator.
4. Who made the flight rings in the Adult Legion's time frame?
Superman, on one of his trips to the future at Christmas time ("Action Comics" 289), found the material used to create mentally-controlled flying belts (not flight rings, as I mis-remembered). The Sannings have an analysis of this issue and think that Superman must have forgotten that they already had flight rings by this point but they're just humoring him.
5. Which Legionnaires' first appearances were posthumous?
Chemical King, Shadow Lass, Kid Quantum, Power Boy, and Reflecto. All but Kid Quantum were originally shown as statues in the Hall of (Dead) Heroes.
6. Which Legionnaires have been related by blood?
Pre-Crisis Superboy and Pre-Crisis Supergirl were cousins; Lightning Lad and Lightning/Light Lass (and their Legionnaires, L2, and L3 counterparts) are siblings; L1 White Witch and L1 Dream Girl are sisters; Kid Quantum I and II are siblings; Cosmic Boy and Magnetic Kid were brothers; Mon-El/Valor and Andromeda/Laurel Gand were cousins 1000 years removed; Invisible Kid II and Computo are siblings; the current Superman and L3 Supergirl are cousins, with L2 Superboy (Kon-El) some sort of relative as he's derived from Superman's cloned DNA; from the animated series, Kell-El was a future genetic derivative of Superman; and the Nolan brothers, who were Ferro Lads in the L1 and an alternate timeline. Plus, of course, the SW6 Legionnaires and their counterparts.
There are a lot of near-Legion relationships, like Shadow Lass and Shadow Kid, and the Tornado Twins and XS, but I didn't include them.
7. What did Mordru serve for dinner when Rokk visited (early v4)? Why?
Elvabird Breast. It was probably the one food Rokk most hated. As anonymous said in the comments, "it was something Rokk grew sick of eating while raiding Imskian food supplies, which Mordru picked from his memories from the Braal-Imsk hostilities..." (I didn't remember that much detail.)
