• Warning: There are major spoilers ahead for “Shazam.”
  • “Shazam” has two extra scenes after the movie.
  • The first teases another villain in the DC universe. The second is a throwaway scene making a small jab at Aquaman.

If you head out to see “Shazam” in theaters, don’t leave right away. The movie has two additional scenes after it ends.

The second scene is a lighter moment to make you laugh. It’s the first scene, which occurs during the middle of the credits, which teases another villain in the DC Cinematic Universe.

In case you headed out early and missed either, we have you covered.

This is your final chance to head back before spoilers.

The first end-credits scene

What happens

Mark Strong's villain, Dr. Sivana, is seen in his prison cell where he has drawn symbols over almost every inch of the walls. He's staring at them when he suddenly hears a menacing voice.

"Primitive simples," says the voice. "You assume there's only one way to gain magic. Oh, no. No. More ways than the mind can imagine."

When he turns around and starts looking for the source of the voice, we see it's a little worm-like caterpillar hanging out near a vent. Sivana looks at the speaking creature in disbelief.

"What in God's name?" Sivana asks aloud.

"I name the gods, Doctor. Not the other way around," the creature continues as he mentions the Seven Realms.

What it means

Put very simply, the caterpillar creature is a character known as Mister Mind, one of Shazam's main foes in the comics. He's teasing the Monster Society of Evil while speaking with Sivana. In the comics, the super villain group has included Black Adam, a character who will be played by Dwyane "The Rock" Johnson in the DC movies.

Who and what is Mister Mind?

Mister Mind is a tiny alien worm who is extremely intelligent. You read that right. Mr. Mind is a worm. He first appeared in the comic in 1943. There have been a few different versions of him in the comics. The most recent version of Mister Mind is a worm from Venus who is the last of his kind and has mind-controlling abilities. That sounds helpful when you're a few inches long.

And what's that Monster Society of Evil?

Similar to DC Comics' Suicide Squad, this has been a group of supervillains that has rotated its roster of characters throughout history. At one point, Adolf Hitler was a member of the Monster Society of Evil.

We could go into a long, winding history of the group, but honestly, what you need to know is that they're a group of bad guys. The iterations that make the most sense to hone in on are ones which include Dr. Sivana and Black Adam. One of the more popular groups that contains both villains also contains the villains Ibac, King Kull, a robot named Mister Atom, and a sorcerer named Oggar.

Who is Black Adam?

Black Adam is another popular Shazam villain who the Rock has been talking about playing in a Warner Bros. movie for years. When he was cast as Black Adam in 2014, he was originally expected to be in the "Shazam" movie. According to Collider, Black Adam felt like too large of a character to have in a Shazam origin story. Warner Bros. is also working on a separate Black Adam movie.

You may have noticed that Black Adam looks a lot like Shazam. That's probably because Black Adam was the original Shazam. Let me explain.

Originally in the comics, Black Adam had serious beef with Shazam because he was originally granted the Shazam powers way back during the times of ancient Egypt. Unfortunately, that version of Shazam took his powers for granted and let them go to his head. He took advantage of and abused his powers. The person who granted them renamed him Black Adam and banished him far away in the galaxy.

Years later, when he finds out about Shazam, a person worthy of the powers he originally obtained, he sets out to destroy him. In more recent years, the character has been retooled as a corrupt anti-hero. That's the version we'll probably see on screen.

As you could imagine, Black Adam essentially has a lot of the same powers as Zachary Levi's superhero. I've always thought of the two as opposites like Superman and Bizarro Superman or the Flash and Reverse-Flash, basically the "evil" version of the hero.

The second end-credits scene

Billy Batson (Asher Angel) is in his room as Shazam with foster brother Freddy Freeman (Jack Dylan Grazer). He's holding up a small fish bowl and asks Freddie to be quiet.

"Don't beat yourself up buddy, you're gonna find someone," Shazam says to the fish. "Yeah, I'm sure because there's plenty of fish in the sea."

Shazam says that last bit sarcastically as he lowers the fishbowl from his face and tells Freddie he was messing with him.

"Of course it's not real. I can't talk to fish," says Shazam. He then asks Freddie what he would even do with that superpower that could possibly be cool.

"I don't know. Maybe command an army of billions in the ocean," Freddy jokes.

Shazam admits that true, but that it's not "that cool."

What it means

This is really just an "Aquaman" gag, and it's one that should have crowds giggling. Shazam is back to testing out what other superpowers he has with Freddie. Earlier in the movie, the two tested out laser vision, flying, and countless other powers.

If you've seen "Aquaman," you'll know that Freddie, unbeknownst to him, is actually referencing the giant battle at the end of Jason Momoa's superhero movie, which makes the moment all the funnier.
