Jeff the Land Shark first appeared in Marvel's West Coast Avengers in 2019, created by Kelly Thompson and Daniele Di Nicuolo. As a literal shark with legs, he quickly stole the hearts of readers with his insatiable appetite and adorable design, eventually leading to his own hit Marvel Unlimited series, 'It’s Jeff!' In the meme world, Jeff represents 'he's just a little guy' energy, frequently used to excuse chaotic behavior or simply to inject pure wholesomeness into a social media feed. His popularity stems from his wordless expressions and the hilarious juxtaposition of a traditionally predatory creature being treated like a domestic house pet.
