What Does He Know? Meme Explained: Origin, Meaning, and Viral Spread
The internet has a unique talent for turning a simple facial expression into a recognizable meme. The “What Does He Know?” meme, also commonly associated with the phrase “Does He Know?”, is a perfect example. It combines mystery, suspicion, and an oddly serious expression to create a reaction image that can fit countless online situations.
Although versions of the phrase have appeared in different meme contexts, one of the most recognizable formats features The Riddler, played by Paul Dano in The Batman (2022). The image became popular after appearing in a thumbnail created by the YouTube channel New Rockstars. It later spread across Twitter, Tumblr, and other social platforms, inspiring edits, redraws, and variations.
But what exactly does the character know? And how did a Batman thumbnail become a widely used internet reaction?
Let’s take a closer look at the origin, meaning, evolution, and popularity of the “What Does He Know?” meme.
What Is the “What Does He Know?” Meme?
The “What Does He Know?” meme is a reaction-image format used when someone appears to possess information that other people do not have.
The basic joke is simple: a person, character, animal, or fictional figure looks unusually serious, mysterious, or suspicious, while the caption asks:
“What does he know?”
A closely related version says:
“Does he know?”
The humor comes from creating the impression that the subject has discovered some hidden truth. In many cases, there is no actual secret. The image simply encourages viewers to imagine that something important is happening behind the character’s expression.
This makes the meme extremely flexible. It can be used to react to rumors, unexpected information, conspiracy jokes, awkward situations, spoilers, or almost anything that makes someone look like they know more than they are saying.
The Riddler “Does He Know?” Meme Origin
The most well-known version of the meme traces back to The Riddler from The Batman (2022).
On March 7, 2022, YouTube channel New Rockstars uploaded a video titled “The Batman: Does Riddler Actually KNOW Batman = Bruce?” The video examined whether Edward Nashton, better known as The Riddler, actually knew that Batman was Bruce Wayne.
For the video’s thumbnail, New Rockstars used an image of Paul Dano’s Riddler with an intense and highly expressive look. The visual immediately communicated suspicion and uncertainty, making it perfect for a meme about someone potentially knowing a secret.
The video eventually accumulated hundreds of thousands of views, exposing the image to a large audience of Batman and pop-culture fans.
However, the image’s meme potential became much more obvious after it started appearing alongside other New Rockstars thumbnail memes.
How New Rockstars Helped Create the Meme
New Rockstars is known for creating YouTube thumbnails designed to make viewers curious about a movie, television show, or fan theory. These thumbnails often feature dramatic facial expressions and exaggerated questions.
That style accidentally created a gold mine for meme culture.
One of the other popular New Rockstars thumbnail formats was “What Was He Cooking?”, which became a viral meme around the same period. As users began collecting and sharing unusual New Rockstars thumbnails, the Riddler image also received attention.
On May 1, 2022, Tumblr user campyvillain posted a compilation featuring several New Rockstars thumbnails, including the Riddler image. The compilation received significant engagement, helping introduce the reaction image to an even wider online audience.
The Riddler’s expression worked particularly well because it looked as though he had uncovered something important.
That visual ambiguity became the foundation of the joke.
The Meme’s Spread Across Social Media
After appearing in Tumblr discussions and meme compilations, the “Does He Know?” Riddler image gradually moved to other social platforms.
Twitter became one of the most important places for its spread. Users began using the image as a reaction whenever another person posted something suspicious, confusing, or potentially revealing.
One early example appeared in May 2022, when the image was used as a reaction to a deleted Twitter post. While the initial engagement was relatively small, the format continued circulating.
A much bigger moment came in June 2022, when Twitter user @SohSketch used the Riddler image as a response to another deleted tweet. The reaction reportedly received thousands of likes and hundreds of retweets within a short period.
This demonstrated one of the most important characteristics of successful reaction memes: the image doesn’t need to tell a complete story by itself.
Users can add their own context.
The same Riddler image could mean:
- “He knows the secret.”
- “He knows what happened.”
- “Does he know about us?”
- “Wait, does he know?”
- “Nobody tell him.”
- “He knows something we don’t.”
The possibilities were practically unlimited.
What Does “What Does He Know?” Mean?
At its core, “What Does He Know?” expresses suspicion or curiosity.
Imagine someone in a group suddenly becoming extremely quiet. They have a strange smile and seem to understand something everyone else has missed.
Someone might post the meme and write:
“What does he know?”
The joke isn’t necessarily about actual knowledge. Instead, it creates a fictional mystery around an ordinary situation.
The meme can therefore be interpreted in several ways depending on the context.
Suspicion
The subject appears to know something secret.
Curiosity
The viewer wants to discover what information the character supposedly possesses.
Conspiracy Humor
The meme can suggest that someone has uncovered a hidden truth that everyone else is unaware of.
Sarcasm
Sometimes the person obviously knows nothing, which makes the serious expression even funnier.
Inside Jokes
Friends can use the format to reference information that only their group understands.
This flexibility is one of the main reasons the meme has remained useful as a reaction format.
Why Is the Meme So Funny?
The humor of the “What Does He Know?” meme comes largely from the contrast between the image and its caption.
The Riddler already has an intense and mysterious expression. When that image is paired with a simple question about what he supposedly knows, the viewer automatically starts looking for an explanation.
This creates a kind of imaginary story.
The character might know something important—or absolutely nothing.
That uncertainty is the joke.
The meme also works because humans naturally try to interpret facial expressions. When someone looks serious, confused, or unusually focused, we instinctively wonder what they are thinking.
The meme takes that everyday experience and exaggerates it.
The Connection to The Batman
The popularity of the meme is closely connected to the cultural impact of The Batman, released in 2022.
Paul Dano’s portrayal of The Riddler gave the character an unsettling and mysterious appearance. Throughout the movie, Edward Nashton presents himself as someone who has uncovered secrets about Gotham’s powerful figures.
That makes the character especially appropriate for a meme centered around hidden knowledge.
The original thumbnail also referenced an important question from the film’s story: whether The Riddler knew Batman’s true identity.
This context gave the image a built-in meaning before internet users started applying it to completely unrelated situations.
Eventually, people stopped needing to know anything about The Batman to understand the joke.
The image simply became shorthand for “This person knows something.”
“Does He Know?” vs. “What Does He Know?”
Although “Does He Know?” and “What Does He Know?” are closely related, they can create slightly different jokes.
“Does he know?” focuses on uncertainty.
It asks whether the person is aware of a particular secret or event.
“What does he know?” takes the joke one step further. It assumes that the person knows something and asks what that information might be.
For example, if a friend suddenly starts smiling during a conversation, “Does he know?” suggests suspicion.
“What does he know?” makes the situation sound even more mysterious.
Both versions are commonly used as variations of the same basic meme idea.

Meme Variations and Edits
Once the Riddler image became popular, users began modifying it.
Some versions changed the caption to “He Knows”, transforming the original question into a statement.
This creates another layer of humor because instead of wondering whether the character knows something, the meme confidently declares that the secret has already been discovered.
Other users created edits and redraws of the image, replacing Riddler with different characters while maintaining the same concept.
This is a common evolution in meme culture. A recognizable image begins as a specific reaction and eventually becomes an exploitable template.
The original character may remain popular, but the underlying joke becomes more important than the original source.
How People Use the Meme Today
The What Does He Know? meme can be used in almost any situation involving suspicious knowledge or unexpected information.
For example, it can be used when:
- A friend suddenly knows about a private conversation.
- Someone predicts an event before it happens.
- A character appears to understand a complicated situation.
- Someone discovers a spoiler.
- A person reacts strangely to breaking news.
- An animal appears to be staring at something invisible.
- Someone makes a suspiciously accurate guess.
- A friend suddenly becomes quiet after hearing a secret.
The meme can also be used ironically.
A person might post the Riddler image after someone makes an extremely obvious observation, pretending that the person has uncovered a massive secret.
That’s where much of its modern humor comes from.
Why Reaction Memes Like This Become Viral
The success of the “What Does He Know?” meme demonstrates how internet memes evolve.
A successful reaction image generally needs three things:
A Recognizable Expression
The Riddler image immediately communicates seriousness and suspicion.
A Simple Caption
“What does he know?” is short enough to understand instantly.
Flexible Context
The image doesn’t depend on one specific joke. It can be applied to thousands of different situations.
This combination allows users to continually create new versions without changing the basic format.
In other words, the meme survives because the community keeps supplying new contexts.
The Evolution of the Meme
Like many internet memes, the “Does He Know?” format did not remain exactly the same after its initial popularity.
It evolved from a specific Batman thumbnail into a general reaction format.
At first, the joke was closely connected to The Riddler and the question of whether he knew Batman’s identity. As the image spread, however, users began removing the original context.
Eventually, the question became more universal:
Who knows the secret?
What did they discover?
Why are they looking like that?
That transition—from a specific pop-culture reference to a reusable internet reaction—is one of the clearest signs that an image has become a genuine meme template.
Why the “What Does He Know?” Meme Remains Relevant
Meme culture moves incredibly quickly. Images can become popular for a few days and disappear just as fast.
The “What Does He Know?” format has an advantage because its central idea is universal.
People are naturally interested in secrets, hidden information, suspicious behavior, and unexpected knowledge. The meme turns all of those ideas into one simple visual joke.
It also doesn’t require extensive knowledge of The Batman.
Someone who has never watched the movie can still understand the basic message simply by looking at the Riddler’s expression and reading the caption.
That accessibility helps reaction memes travel between communities and platforms.
Final Thoughts
The “What Does He Know?” meme is a great example of how internet culture can transform a movie thumbnail into a completely independent form of comedy.
Its most recognizable version comes from a New Rockstars thumbnail featuring Paul Dano’s Riddler from The Batman (2022). After appearing in meme compilations and spreading across Twitter and Tumblr in 2022, the image developed into a flexible reaction format.
What started as a question about whether The Riddler knew Batman’s secret eventually became a much broader joke about suspicion, hidden knowledge, and curiosity.
Whether someone really knows something or is simply making a confused face, the meme gives the internet one perfect question:
