Fantastic Four Gang Sign is a meme based on comic book panels showing Mr. Fantastic holding up four fingers, which became reinterpreted as a gang sign in 2022 and went viral on TikTok in early 2025 after the character's addition to Marvel Rivals, spawning the catchphrase 'Ain't That Fantastic FN.'

Overview

Fantastic Four Gang Sign is a meme centered on comic book panels depicting Mr. Fantastic (Reed Richards) holding four fingers up in front of his body. The gesture, a recurring visual in Fantastic Four comics since at least 2008, became recontextualized online as a gang sign starting around 20221. The "4's Up" hand signal is often associated with signaling danger in gang culture, and users applied this interpretation humorously to the superhero imagery.

The meme experienced a major resurgence in January 2025 when the Fantastic Four characters were added to the hero shooter game Marvel Rivals2. TikTok users began creating ironic edits featuring Mr. Fantastic with a photoshopped durag while doing the four-finger sign, often set to Travis Scott's "90210." These posts also popularized the catchphrase "Ain't That Fantastic FN," incorporating the Green FN internet slang popular among younger users1.

How It Spread

Following the initial post, the Fantastic Four Gang Sign meme spread rapidly among Marvel Rivals players in January 2025. On January 11th, 2025, TikTok user @belowaveragegamimg posted what became the earliest version of the Mr. Fantastic durag edit3. The video accumulated over 2.9 million plays and 548,000 likes within a month. In the comments of that post, user @blindstrike00 coined the catchphrase "Ain't that fantastic fn," which received approximately 44,000 likes and became inseparable from the meme1.

The format continued evolving as more creators added their own spins. On January 18th, 2025, TikTok user @vickeditz uploaded a fan edit titled "Fantastic Aint It FN" using another panel of Reed Richards with the gang sign, gaining over 99,000 plays and 15,000 likes in two weeks4. The meme consistently paired the edited comic imagery with Travis Scott's "90210" as background music, creating a recognizable audiovisual template.

The catchphrase "Ain't That Fantastic FN" became its own trend on TikTok, with users applying it beyond just the comic panels to various Marvel Rivals gameplay clips and other content1.
