You can whatever you want with your Doomsday monster, but in the comics it was created/developed by a Kryptonian scientist to be the perfect killing life form. The arid vacuum of space wouldn't kill it. And because it's Kryptonian, you can't point it at our sun without supercharging it. Maybe these Supermen actually put it on a collision course with a white dwarf so that ol' Doomy would be trapped in the star's gravity well until it collapsed into a black hole. Then there's no way to know what would happen to the creature, assuming it could survive even that. And I think even Superman's ethical prohibition on taking lives would survive Doomsday's demise.
Yes! They hurled him out into space, not toward the Sun, not with the intention of killing him, but with the goal of putting him on a path that shouldn't collide with anything, at least not for many many many light-years

At least, that was their intention!
I like this tale. So they've taken care of fifteen Doomsdays now? Wow. That means that there are at least fifteen different examples of Lois Lane in the multiverse. Doomsday wouldn't bother with a world without a Lois since there probably wouldn't be a Superman there without her. I hope none of the Loises happened to be on her way to visit her Clark when the Super-Committee To Eliminate Doomsday (SCTED) showed up to help take care of the local monster.
SCTED! I like it! It is probably a good thing Lois was not around when they showed up!
Ironic that you untwisted your own plot for this tale. Very inventive. Keep up the great work. And don't forget about the follow-up to Anchor, okay?
I'm ready to start posting Part 2 if people want to read it! I know a few people are still finishing up Part 1. So hopefully soon!
Thank you for reading, and, as always, thank you for the thoughtful comments!!!
