If you grew up watching The New Batman Adventures in the late 90s, one specific image probably still haunts your brain: a terrified little girl in a red raincoat fleeing through the rainy, neon-soaked streets of Gotham. You might remember Tim Drake—the second Robin in the DC Animated Universe—falling head over heels for her, only for the story to take a turn so dark it felt more like a horror movie than a Saturday morning cartoon.
That girl was Annie. And she wasn't actually a girl.
The Clayface DC disguise little girl is officially known as one of the most tragic "one-off" characters in comic book history. She wasn't just a costume or a clever bit of acting by Matt Hagen; she was a sentient piece of his own biomass that gained a soul. Honestly, it’s the kind of body horror and emotional trauma that modern writers still struggle to replicate.
Who Exactly Was Annie?
Let’s get the facts straight because there’s often some confusion about whether Annie was a real person Clayface kidnapped. She wasn't.
After the events of the Batman: The Animated Series episode "Mudslide," everyone thought Clayface (Matt Hagen) had dissolved into nothingness in the ocean. He survived, but he was a mess. His body was falling apart, literally leaking into the Gotham harbor. To scout the city and see if it was safe for him to resurface, he used a new, desperate ability: he shed a piece of his own clay and molded it into a small, inconspicuous child.
He basically "birthed" a scout.

The plan backfired. Because she was separated from the "main" Clayface for too long, the girl developed amnesia. She forgot she was a scout. She forgot she was made of mud. She became Annie—a lonely, frightened child who genuinely believed she was running away from an abusive father.
Why the Annie Episode Still Hits Different
The episode "Growing Pains" (aired February 28, 1998) is widely considered one of the best in the entire franchise. Why? Because it forced a young Robin to deal with a concept even Batman struggles with: the death of someone who technically never existed.
- The Design: Annie was modeled after Mathilda (played by Natalie Portman) from the 1994 film Léon: The Professional. The short black bob and the oversized coat weren't accidental; they were meant to project vulnerability.
- The Twist: When Robin finally corners the "man" chasing Annie, he discovers it’s just another shell being operated by the real Clayface, who is hiding in the sewers.
- The "Murder": This is the part that messed us all up. At the end of the episode, Clayface doesn't just "catch" her. He absorbs her. He pulls her back into his mass while she screams for help.
Robin later tries to have Clayface charged with murder. The police laugh it off because, legally, you can't murder a piece of yourself. But for Tim Drake, and for the audience, it was the coldest execution Gotham had ever seen.
Is Annie in the DC Comics?
This is where things get interesting for the lore nerds. For a long time, Annie was exclusive to the DC Animated Universe (DCAU). She was a creation of Paul Dini and Robert Goodman specifically for the show.
However, DC has a habit of bringing popular TV characters into the "main" comic continuity—look at Harley Quinn or Renee Montoya. Annie eventually made her way into the Batman Adventures comics, which continue the style of the show. In more recent years, we’ve seen variations of this "daughter of Clayface" trope pop up in different ways.

- Katherine Karlo: In the Gotham Academy series, we meet Katherine, who describes herself as a "sentient piece of viscoelastic protoplasm." She’s basically a more monstrous, teenaged version of the Annie concept—a daughter of Basil Karlo (the original comic Clayface).
- The Harley Quinn Show: The 2019 animated series played with this too. Clayface loses a hand, and the hand develops its own personality, becoming a separate entity. It’s played for laughs there, but the DNA of the Annie story is clearly present.
The Science of the Clayface "Spawn"
How does a pile of sentient mud create a little girl with a conscience? In the DCAU, it's explained as a side effect of the chemicals Matt Hagen was exposed to in the Gotham sewers. These chemicals stabilized his failing form but also gave his cells a weird kind of autonomy.
Basically, every "cell" of Clayface carries a fragment of Hagen’s personality. When Annie was created, she didn't get the "villain" part of him. She got the part that was lost, innocent, and scared. She was the person Matt Hagen used to be before the accident and the ego took over.
Does it happen often?
Not really. Most versions of Clayface—whether it’s Basil Karlo, Matt Hagen, or Preston Payne—prefer to keep their mass together. Splitting off a piece of yourself makes you weaker and smaller. The only reason Hagen did it was because he was too injured to walk the streets himself.
What Most People Get Wrong About the Disguise
A common misconception is that Annie was "acting" or that Clayface was "remote-controlling" her.
That’s not true. Annie had 100% free will.

She wasn't a puppet; she was a separate consciousness. That’s what makes the ending so horrific. When she sacrifices herself to save Robin, she’s making a choice as an individual. When Clayface absorbs her, he isn't just "putting on a coat"—he’s consuming a living mind that begged to stay alive.
Honestly, it’s one of the few times Batman actually looks uncomfortable. He knows he can’t put Clayface on trial for this, but he also knows he just watched a "child" die.
Actionable Takeaways for Fans
If you're looking to dive deeper into this specific corner of DC lore, here is what you should do:
- Watch "Growing Pains": It's Season 1, Episode 8 of The New Batman Adventures (often listed as Season 3 or 4 of Batman: The Animated Series on streaming platforms like Max).
- Check out "Gotham Academy": If you want to see how the comics handled a "sentient clay daughter," read the Gotham Academy run featuring Katherine Karlo. It’s much lighter in tone but hits some of the same identity themes.
- Look for the "Léon" References: Watch the episode again and look at Annie’s movements. The animators at Studio Tokyo (who worked on this episode) put incredible detail into her body language to make her feel distinct from the heavy, lumbering Clayface.
The story of the clayface dc disguise little girl is a reminder that the best superhero stories aren't about the punches thrown. They’re about the humanity found in the most monstrous places. Annie wasn't just a disguise; she was the best part of a bad man, and Gotham wasn't ready to let her stay.
To understand the full scope of Clayface's powers, compare his DCAU origin in "Feat of Clay" with his comic book debut in Detective Comics #40. You'll see how the writers merged the actor persona of Basil Karlo with the shapeshifting tragedy of Matt Hagen to create the version that birthed Annie.
