Or moreso how no one else has that story, haha
I think you can leave out the Superfamily on the simple basis that they would never actually have a death battle with Superman. And I think that even includes other Kryptonians like Zod, because it's a pretty bad risk to take. Doomsday will always be unique because he's engineered for death, *actually* brought it, and can't be defeated the same way twice so even killing him is a bad strategy if not an immoral one.
Sounds like he's gonna get significantly worse by association. Granted I haven't seen any of this Lazarus stuff
