Im Not Ralsei But Im Asriel
Im Not Ralsei But Im Asriel is a reaction face and catchphrase pulled from a 2020 Deltarune fan animation in which Ralsei drops his disguise and reveals himself as Kris' brother Asriel. The joke came back to life in April 2025 when the YouTube dubbing channel Bitti re-dubbed the original animation and started reusing the reveal face as a running gag. Twitter/X user Teox has since spread it further through his 'Deltarot' skit series.
Overview
Im Not Ralsei But Im Asriel is a reaction face and catchphrase pulled from a 2020 Deltarune fan animation, where the character Ralsei drops his disguise and reveals himself as Asriel, Kris' older brother2. The specific frame from that reveal, a wide-eyed close-up of Asriel's face, turned into a recurring visual gag inside the Deltarune fandom starting in April 20251. Fans edit the face over Ralsei or other characters when a scene reaches an emotional or unhinged peak.
The joke leans on a long-running fan reading of Deltarune. Ralsei looks a lot like Asriel from Undertale, and his name is a direct anagram of Asriel, which the community treats as basically canon even though the games have never spelled it out5. A later Bitti upload added an on-screen phrase, "I'M NOT [___] BUT I'M ___" over the face, which gave the joke a text template people could fill in with any two Undertale or Deltarune characters they wanted1.
Most modern uses trace back to a YouTube dubbing channel called Bitti and to Twitter/X user Teox, both of whom pull the face into their own animated shorts as a running bit4.
How It Spread
How to Use This Meme
The typical build drops the Asriel-reveal face over another character's face at a moment of high emotion, most often over Ralsei himself when a scene has him breaking down or losing composure. Common versions overlay the text "I'M NOT [something] BUT I'M [something]" on the image or clip, usually with the first blank being what the character is presenting as and the second blank being what they "really" are. Deltarune fluency helps read the joke, but the face-swap element still lands as a visual gag on its own without the Undertale context.
Fun Facts
- Ralsei's name is a straight anagram of "Asriel," and the community has treated the resemblance as a wink at Undertale since Deltarune Chapter 1.
- Karim Hani's original 2020 animation is no longer available on YouTube; the version most modern fans have seen is the Bitti dub.
- Bitti was originally called Starism Plus, an extras channel for a Roblox YouTuber named Starism, before its April 2025 rebrand.
- The catchphrase "I'M NOT [___] BUT I'M ___" was not part of the original animation and only appeared in a later Bitti upload as an on-screen text edit.
- Teox coined "Deltarot" for his short satirical Deltarune skits, and the Asriel face slotted into that series as a recurring bit.
