* Why is it that the villains have no compunction killing Superboy/Superman? True, he's trying to stop him, but they should know Superboy/Superman is ''really'' important to their history, given how he's saved ''the universe'' a number of times in the 20th/21st century/ Especially Legion villains born on Earth, who's premature killing of Superman would have a far more damaging ripple effect.
** Maybe they think it's a different guy?
** Quite possibly. How much has Superboy ''really'' announced that whole "I'm the real thing from the past and need to get back there alive and well or the entire timeline falls apart!" deal, anyway...and how many supervillains would be the sort of person to ''believe'' that even if word got around to them?
** On the flip side, what are the Legion of Superheroes ''thinking'' when they send Superboy into the future for youthful hijinks? Even if it's a small chance, he could die and thus unravel the time-stream.
*** Perhaps part of Superman being such a great hero (on pre-Crisis Earth-1 anyway) was ''from'' the experience, training, etc. he'd gained by being a Legionnaire in his youth?
* If Brainiac 5 is so smart, can't he make Wildfire a containment suit that looks and feels more like an ordinary human? It would sure make things a lot easier with Dawnstar.
* The original Legion Clubhouse. Its about the size of a phone booth on the outside, as big as a shopping mall on the inside. Is this a case of UnitsNotToScale or BiggerOnTheInside?
** Definitely a case of UnitsNotToScale. There are far too many rooms to fit, but they're all pretty small, and all have curved walls.
** Wasn't the clubhouse said to be BiggerOnTheInside due to existing in the fourth (spatial) dimension, at least in the Silver Age? Pretty sure I remember reading this in one story.
** The Silver Age version explicitly used tesseract technology. Like the TARDIS, its entirely bigger on the inside than it is on the outside.
* Originally, the Legion of Superheroes Era was set 500 years in the future, but it became 1000. On a meta-level, what was the retcon for?
