One thing I didn't understand is why Doomsday set to Superman is over

Doomsday is basically Superman’s ultimate physical challenge.

If you mean why Doomsday is set up as Superman’s next major threat, it’s because he represents the kind of physical challenge Superman can’t simply overpower easily.

You know how he could’ve defeated doomsday? Throw him into space and let him float forever.. simple.. but nope.

Do you understand yourself dipshit

In Batman v Superman, Superman impales Doomsday with a Kryptonite spear while Doomsday fatally impales Superman with his arm bone spike.

Best Superman series ever

In the original comic, both characters hit each other with maximum force at the exact same moment. Doomsday's sheer physical force beats Superman to death, while Superman's final, desperate blow kills Doomsday.

Aweful

The conflict between Superman and Doomsday ends because they inflict fatal blows on each other simultaneously, leading to their mutual destruction.

What the title this movie @grok

Could MCU Thor or Hulk defeat Doomday from this show by themselves?

Whether in the iconic 1992 The Death of Superman comic storyline or the film Batman v Superman: Dawn of Justice, the fight reaches its end for a few specific reasons.

Unlike typical battles where Superman can retreat to absorb solar energy or use strategy, Doomsday forces a relentless, brute-force brawl where Superman has no choice but to sacrifice his life to protect others.
