"On through space rotates Krypton, toward its inexorable rendezvous with a cruel destiny, but at the sky palace, two pairs of lovers propose a toast, gallantly unafraid…”
"Superman’s Return to Krypton!" (not to be confused with "Superman Returns to Krypton!", the 1949 story wherein Superman traces a Kryptonite back through time and first learns where he came from, which is a nice story itself, albeit definitely no longer canon after the advent of Super-Memory) is a genuinely great, classic Superman story.
The setup is that due to a freak accident, Superman ends up hurled into the past, landing on Krypton some weeks or months before it explodes. Since he doesn’t have superpowers on Krypton, he can do nothing to prevent or escape the coming destruction, and instead takes the time to hang out with his parents, get to know the world where he was born, and to fall in love with a Kryptonian actress named Lyla Lerrol, with whom he shares many makeouts:
It’s all incredibly bittersweet and surprisingly touching, as Superman finds a happy, passionate life with Lyla and his parents, all the while knowing it’s going to end violently and soon.
I’ve excerpted the pivotal moment above, as the four of them celebrate in the face of certain doom.
Of course, just before the explosion, Superman is hurled away from Krypton in another freak accident, but somehow that just makes it all the more sad.
I would highly recommend giving it a look, along with everything else I’ve been reading through lately. There’s great stuff, and the stuff that’s terrible is at least terrible in interesting ways. You can find them for cheap in the Showcase Presents: Superman (as well as Superman Family and Supergirl) volumes, in which this story is collected in Vol. 2.
If everyone goes out and reads those I’ll seem less weird for being fascinated by these things, and that’s really my goal here.
