AI Summary

This video analyzes the ending of the Supergirl movie and theorizes about its implications for the DC Universe, particularly the upcoming Superman film featuring Brainiac as the villain. The creator connects Kara's actions and her father's role as a swordsmith to potential plot points involving nth metal and the larger DCU storyline.

[00:01]
Brainiac as Next Villain

The next Superman film will feature Brainiac as the villain, alongside Lex Luthor and Supergirl.

[00:15]
Brainiac's Origin and Kara's Motivation

If Brainiac is a Kryptonian supercomputer that destroyed Kara's home world, it explains why the movie had Kara kill Krem—she seeks vengeance for her civilization, not just her dog.

[00:39]
Kara's Arc and Father's Role

In the movie, Kara's father is a swordsmith, whereas in the comics he is a rock farmer. This change may be significant for future plot developments.

[01:05]
Symbolism of the Sword

In the comics, the sword belonged to Krem, adding symbolism as Kara used the same weapon that killed her father. The movie ditched this, possibly to set up a different narrative.

[01:18]
Nth Metal Connection

The swords are made from nth metal, one of the strongest metals in the universe, also used in Hawkgirl's mace. Brainiac constantly upgrades himself, so he might seek nth metal for a new form.

[01:32]
Potential Plot for Superman Film

Kara could bring Clark to her collection of nth metal swords, which might be useful against the real big bad of the DCU, Darkseid.

The video theorizes that the Supergirl movie's changes—particularly the swordsmith father and nth metal—are deliberate setups for the upcoming Superman film, where Brainiac and possibly Darkseid will be central threats.

[00:01] sets up Brainiac and what's next for the DCU. We know that the next Superman film the Man of Steel working with Lex Luthor. Supergirl is also confirmed to be in that movie, but most importantly, the villain will be Brainiac. Next to

[00:15] Lex Luthor, Brainiac is the Superman villain, but he's never actually been on the big screen. But here's the thing, if the movie adapts Brainiac's origin that he was a Kryptonian supercomputer that was responsible for destroying Kara's

[00:27] home world, well, I think this explains why the movie chose to have Kara kill Krem at the end. See, Ruthie may have let go of her quest for vengeance, but messing with her dog, so imagine what

[00:39] destroyed her entire civilization. And I think this points to her arc in Man of movie is that Ruthie's father is a swordsmith. In the comics, he's a rock Wouldn't that just make him a miner? I don't know, maybe on his planet like

[00:53] rocks grow in the field and he farms them. I don't know. So, why make her dad a swordsmith instead of a rock farmer? I mean, in the comic, the sword actually belonged to Krem, so there was like added symbolism that Ruthie wanted to

[01:05] use the same evil object that killed her father to kill the sword's owner. Why would the movie ditch that symbolism? And why would the movie end with Ruthie Well, I have a theory. So, she says that her dad made his weapons from the

[01:18] universe, one of the strongest metals in existence is called nth metal. For instance, Hawkgirl's mace is made out of the metal in the comics. Now, Brainiac, like Ultron, is constantly upgrading himself. So, if he's upgrading himself,

[01:32] new form from the strongest metal he could find. So, in the movie, if Kara Kara can be like, >> I'm no god. >> And then bring Clark to shop Ruthie's collection of nth metal swords. Nth

[01:45] which could come in handy against the real big bad of the DCU, Darkseid.
