I learned that many book friends are confused about the destruction of Krypton. French Fries are here to give you a simple popular science. If there are any fallacies, please correct me.

After all, how could a top civilization that can dominate 28 galaxies perish because of the explosion of the parent star?

In fact, there are three main statements that are more well-known.

1. Krypton explodes, naturally perishes

Take the most well-known dceu as an example, the dc movie series universe opened in 2013.

In this movie, Kryptonian civilization is a top civilization. Interstellar navigation is common for them. It has colonized 28 galaxies, and even has something like the "World Engine" that can change the surface ecology at will.

After 100,000 years of rapid development, the Kryptonians have abandoned the use of natural reproduction to give birth to offspring, because they can modify their genes at will, create various specialized Kryptonian templates, and even create monsters like Destruction Day.

Just imagine that during the nearly 100,000 years of exploration, no other civilization where Kryptonians went could pose a force threat to it.

Just find a stable planet and transform it into a new Krypton and create a population at will.

In other words, the process of development at this stage is purely repeated between expanding territory and transforming the planet.

After repeated countless times, the Kryptonians gradually lost their desire to explore the universe, and genetic technology has reached its peak and cannot break through again. The social class has further solidified. The general's son will always be a general, and the scientist's son will always be a scientist.

Finally, the Kryptonian decision-making layer believed that under this model, there was no room for the development of civilization to rise, and there was no meaning to continue exploring space, so it gave up the colonial planet outside and the tortoise retracted its parent planet.

This is the main premise of the destruction of Krypton!

Tens of thousands of years have passed, and due to the excessive exploitation of Krypton's nuclear resources, Boom's Krypton exploded.

Many films and TV series and comics use similar settings.

2. Figure madman Brenniak

There are many Brenniak, generally referring to Fril Dax (vril     Dox), which is an artificial intelligence (ai) created by Colu.

But after the subsequent self-evolution and replication, not only did the scientists who controlled this planet, but also conquered the entire planet. In the process of continuous upgrading, they not only evolved their own abilities, but also evolved their own greed, jealousy, and hatred.

This guy is rampant in the universe, using the reduction of light, and likes to reduce the best characteristics of various civilizations into specimens and put them in his own spacecraft for collection.

The nickname is given by a figure maniac.

In some versions of the comics, Breniak and Krypton's feudal alliance will destroy the Kryptonian core.

In order to collect figures, I also exploded Krypton because the only one is the most memorable one.

There are also some versions, Breniak itself is Krypton's artificial intelligence, which later came from self-awakening and rebellion, and exploded Krypton.

So, in addition to natural reasons, generally DC screenwriters like to set Breniak as the murderer of Krypton's destruction, and then Superman has a reason to do it...

Three, art is explosion

In the comic "sandman:     endless   nights", the main god Rao of Krypton happily attended a party of the gods.

In this party, Rao encounters despair among the seven giants of the Endless Family.

Let me first introduce Rao and Despair.

Rao is the main god of Kryptonian civilization, and his god is not an indigenous god like Zeus or Odin, but a multiverse-level powerful man who has participated in the encirclement and suppression of Sandman.

It is said that the Al family and the Zod family contain some of its bloodlines.

Like Sandman, Despair is a member of the Endless Family. There are seven members of this family, all of which are all omnipotent cosmic powerhouses. One thought can erase a multiverse and be at the same level as the Court of Life.

At this party, Rao was sitting there alone and drinking well, but a big belly woman came to him and said, "If a planet's civilization flourishes and destroys it all at once, leaving only a survivor to commemorate it, isn't it an artistic beauty?"

How could the multiverse-level Rao resist the desperate despair of the all-round cosmic level? After thinking about it carefully for two seconds, he felt that this idea was good...

Then, the fate of all Kryptonians in the DC multiverse was decided in this conversation.

So, Krypton died for art...

Four, summary

In fact, after saying so much, all the reasons are just written by the screenwriter for the rational appearance of Superman.
