A complete guide to Marvel's most unlikely fan-favorite — from throwaway villain to Eisner-winning solo star
Manga Guides Marvel | Updated June 2026Picture this: a writer sits down in 2019 to outline West Coast Avengers, a Marvel title already stacked with eccentric characters. She needs a menace. Not a world-ending cosmic horror, not a brooding antihero — something weirder. She conjures up a swarm of land sharks, creatures with stubby legs and rows of teeth, tearing through suburban streets. One of them is supposed to be a nameless monster-of-the-week. Except something about the little guy sticks. He's got round eyes, a compact body, and the energy of a golden retriever trapped inside a Great White's silhouette. Kelly Thompson names him Jeff. And five years later, Jeff has an Eisner Award, a starring role in a 40+ issue digital series, his own playable slot in Marvel Rivals, and a fanbase that rivals characters who have been around for six decades.
If you're here because you saw a chubby purple shark on TikTok and thought, "Wait, this guy has comics?" — you're not alone. Jeff the Land Shark has become one of those rare Marvel characters who transcends the page, and the good news is that his comic run is genuinely excellent. This guide walks through every major appearance, explains what makes these stories work, and shows you exactly where to find them.
The Bite That Started It All: West Coast Avengers #7
Jeff made his debut in West Coast Avengers #7, cover-dated March 2019. Written by Kelly Thompson with art by Daniele Di Nicuolo, the issue dropped a pack of land sharks into the middle of Los Angeles as part of a larger chaos event. The team — Hawkeye (Kate Bishop), America Chavez, Gwenpool, and the rest — had to deal with creatures that were essentially sharks with legs, chomping through the city like they owned it.
Most of the land sharks were dispatched or sent back wherever they came from. But one lingered. A smaller specimen who didn't attack anyone aggressively, who seemed more curious than predatory. Gwenpool, the fourth-wall-breaking mercenary who treats the Marvel Universe like her personal sitcom, immediately latched onto him. She named him Jeff. The name stuck because of course it did — it's the most aggressively mundane name you could give a prehistoric sea monster with legs.
What made this moment resonate wasn't the action or the spectacle. It was the contrast. You had Gwenpool — loud, meta, unhinged — cooing over a creature that should have been terrifying. Di Nicuolo's art sold it perfectly: Jeff's oversized eyes, his slightly confused expression, his compact body language that read more "lost puppy" than "apex predator." Readers responded instantly. Social media lit up with fan art within days of the issue hitting shelves.
"I didn't set out to create a mascot. Jeff was supposed to be a one-off gag. But the second Daniele drew those eyes, I knew we had something. The internet told me within 24 hours." — Kelly Thompson, reflecting on Jeff's creation
Gwenpool's Influence on Jeff's Character
Gwenpool and Jeff became an inseparable duo during the remainder of the West Coast Avengers run. Their dynamic was simple and effective: Gwenpool talked at Jeff constantly, and Jeff stared back with the blank, loving expression of a pet who has no idea what's happening but is thrilled to be included. This one-sided banter became a comedic engine that Thompson mined repeatedly. Gwenpool would explain her elaborate schemes to Jeff. Jeff would blink. Something would explode. It was perfect.
The character also showed up in the Gwenpool solo material that spun out of this era, appearing in promotional art and backup stories. But his anchor remained the team book, where he functioned as part mascot, part teammate, and part running joke. He attended Avengers meetings. He sat on the couch. He ate things he shouldn't have. The mundanity was the comedy.
A Design That Breaks Every Shark Rule
Real sharks are sleek, hydrodynamic, and built for speed. Jeff is none of those things. His design deliberately subverts every expectation you might have about a shark character:
- Body shape: Jeff is essentially a bowling ball with teeth. He's round, compact, and about the size of a corgi. There's nothing aerodynamic about him.
- Legs: Instead of fins, Jeff has four stubby legs that look borrowed from a Komodo dragon. They're short enough that his belly nearly scrapes the ground when he walks.
- Eyes: Massive, forward-facing, and expressive. Gurihiru, the art team behind the solo series, pushed Jeff's eyes even larger and rounder, giving him an almost chibi quality.
- Color: A muted purple-blue on top fading to a lighter underbelly. Not the cold grey of a real Great White. The palette is warm, approachable, almost plush-toy-like.
- Teeth: He has plenty of them — sharp, visible, and occasionally the source of sight gags where he grins way too wide. But they never look threatening. They look like a jack-o'-lantern.
- Tail: A small, almost vestigial tail that wags when he's excited, completing the "puppy in a shark suit" illusion.
The genius of this design is that it works at every scale. On a full comic page, Jeff is a small background gag. On a phone screen — which is where most fans first encountered him through social media clips and Marvel Unlimited panels — he fills the frame with personality. When Gurihiru took over art duties for the solo series, they refined the design further, smoothing his lines and making his expressions even more elastic. The result is a character who can convey jealousy, delight, confusion, smugness, and heartbreak without ever speaking a word of dialogue.
Kelly Thompson: The Writer Who Refused to Let Jeff Be a Joke
It would have been easy for Jeff to remain a background curiosity — the quirky pet that shows up for panel three, does something cute, and exits. Plenty of Marvel characters have landed in that exact limbo. But Kelly Thompson had other plans, and her track record speaks for itself: she's the writer behind some of Marvel's most commercially successful runs of the 2020s, including Captain Marvel, Black Widow, and Sabrina the Teenage Witch (for Archie). She knows how to build audience around a character.
Thompson's approach to Jeff was deceptively smart. She never made him talk. Never gave him internal monologues or telepathic connections or any of the narrative crutches that writers use to make non-verbal characters "work" on the page. Instead, she committed fully to physical comedy and visual storytelling. Jeff communicates through body language, facial expressions, and the occasional well-timed chomp. This forced every artist who drew him to do the heavy lifting, and it's a big reason why the character translates so well across different media.
The Gurihiru Partnership
When Jeff got his solo series, Thompson paired him with the Japanese art team Gurihiru — known for their work on Spider-Man Loves Mary Jane and various Power Pack titles. The match was ideal. Gurihiru's style is clean, colorful, and expressive, with a natural affinity for cute characters. They drew Jeff the way a Pixar animator would design him: every panel a new expression, every movement weighted and intentional.
Under Gurihiru's pencils, Jeff became a character who could carry entire pages alone. A sequence where Jeff investigates a suspicious sandwich gets the same visual attention and comedic timing that a superhero fight scene would receive. That level of craft is what elevated the solo series from "cute tie-in" to "genuinely funny comic that happens to star a shark."
It's Jeff! — The Solo Series That Nobody Saw Coming
In September 2021, Marvel launched It's Jeff! as an Infinity Comic — a vertical-scrolling digital-first format exclusive to Marvel Unlimited. The premise was minimal: follow Jeff through his daily adventures in the Marvel Universe. No grand stakes, no multiverse crises, just a small shark navigating a world built for people fifty times his size.
The series launched weekly and quickly became one of Marvel Unlimited's most-read titles. By 2023, it had surpassed 40 issues — an extraordinary run for what began as a digital experiment. Here's what made it click:
- Self-contained stories: Most issues run 6-8 panels vertically. You can finish one in under two minutes. That's by design — it's perfect commuter reading.
- Marvel cameos: Jeff encounters major characters regularly. He's met Spider-Man, Captain America, the X-Men, and even cosmic entities like Galactus. The humor comes from the size and power gap — Jeff treats a Celestial the same way he treats a hot dog vendor.
- Emotional range: Not every strip is a gag. Thompson and Gurihiru occasionally deliver quiet moments — Jeff curled up next to a sleeping hero, Jeff staring at the ocean with something that might be longing — that give the series genuine depth.
- Running gags: Jeff's relationship with food. His rivalry with inanimate objects. His tendency to appear in places he absolutely should not be. These build across issues in ways that reward long-term readers.
Season Highlights
The series is loosely organized into seasons, each with recurring themes:
Season 1 (2021-2022): The introductory run. Jeff explores New York City, meets the Avengers, and establishes his personality — curious, hungry, and unbothered by danger. Key issues include Jeff's first encounter with Spider-Man (who is deeply confused) and his visit to the Baxter Building.
Season 2 (2022-2023): The series hits its stride. Longer story arcs emerge, including a multi-issue sequence where Jeff accidentally joins the X-Men. The art becomes more detailed and expressive as Gurihiru settles into the character.
Season 3 (2023-2024): Bigger guest stars and more ambitious premises. Jeff interacts with cosmic-level characters. The "Duck Defender" arc becomes a fan favorite.
Season 4 / Brand New Week (2024-present): Following the Marvel Rivals explosion, the series continued with new energy. It's Jeff: Brand New Week launched in 2026, signaling that Marvel has no intention of slowing down.
The Physical Comic That Changed the Game
For all its digital success, It's Jeff! remained trapped behind a paywall for years. That changed in April 2023 with It's Jeff #1: Let's Get Physical — a traditional print one-shot that adapted and expanded material from the digital series. Priced like a standard Marvel one-shot, it gave comic shop readers their first chance to hold Jeff stories in their hands.
The one-shot sold through multiple printings. A fourth printing was announced to meet ongoing demand, which is remarkable for a character who had never appeared in a major film, TV show, or video game at that point. The cover art — Gurihiru's Jeff in various poses — became poster-worthy collectible material almost immediately.
This was followed in November 2023 by It's Jeff: The Jeff-Verse #1, a larger one-shot that leaned into multiverse concepts. Jeff encountered alternate-reality versions of himself: cowboy Jeff, pirate Jeff, noir detective Jeff, even a version that was just a regular shark. The meta-humor was thick, and it resonated with an audience that had spent years making their own fan interpretations of the character.
That same one-shot went on to win the 2024 Eisner Award for Best Humor Publication — one of the most prestigious honors in the comics industry. A land shark comic, born as a throwaway gag in a team book, had beaten out every other humor comic published that year. The moment validated something that fans had been saying for years: Jeff's comics aren't just cute. They're genuinely well-crafted.
Marvel Rivals and the Viral Explosion
In December 2024, Jeff joined the roster of Marvel Rivals, NetEase's hero-based shooter that had already attracted millions of players. As a playable support character, Jeff could heal teammates, create bubble shields, and — in his most iconic ability — swallow enemies whole and spit them off the map.
The game's release did something that five years of comics had been building toward: it put Jeff directly into the hands of people who had never opened a comic book in their lives. The result was immediate and overwhelming.
The numbers tell the story: Within weeks of Marvel Rivals launching, Jeff-related content dominated TikTok, Twitter/X, and Reddit. Fan art production spiked by orders of magnitude. Plush toy preorders sold out within hours. Google Trends for "Jeff the Land Shark" hit their all-time peak in January 2025. The Washington Post ran a feature specifically about how a land shark became the surprise breakout star of a triple-A video game. Comic shops reported that back issues of West Coast Avengers and It's Jeff! one-shots were being pulled from dollar bins and repriced as key issues.What made Jeff's Marvel Rivals success feel earned rather than manufactured was the character's genuine history. This wasn't a corporate mascot invented for a game — Jeff had five years of comic stories, an established personality, and a creative team that had been developing him with care. Players who fell in love with Jeff in the game could immediately go read dozens of comics that featured the same character, written by the same writer, drawn by the same artists. That continuity between media is rare, and it's a big reason why Jeff's fanbase converted so effectively from gamers to comic readers.
Other Notable Comic Appearances
Beyond his main series, Jeff has popped up across Marvel's publishing line:
- Deadpool #1: Jeff and Deadpool in the same issue. Exactly as chaotic as you'd expect.
- Infinity Paws #1 and #8: A crossover event featuring Marvel's animal characters, including Lockjaw, Throg, and — naturally — Jeff.
- Marvel Meow #8: A companion to the cat-themed Infinity Comic, proving Jeff can coexist with feline co-stars.
- Venom War: It's Jeff! #1 (2024): A tie-in to the Venom War event, where Jeff confronted symbiotes. Yes, really. The tonal whiplash was the entire point, and it worked beautifully.
- Jeff Week #1: A special promotional issue celebrating Jeff's growing presence in Marvel's lineup.

Reading Tips for New Fans
Start with the Infinity Comics. The It's Jeff! digital series is the purest expression of the character. Each issue is short, standalone, and funny. You don't need any prior Marvel knowledge to enjoy them. Marvel Unlimited offers a free trial, so you can sample the first several issues before committing to a subscription.
Then grab the one-shots. Let's Get Physical and The Jeff-Verse are the print comics that give Jeff a more traditional comic experience — full pages, panel layouts designed for left-to-right reading, and slightly longer stories. The Jeff-Verse one-shot is the Eisner winner and worth tracking down on its own merits.
For the origin story, read West Coast Avengers #7. It's available digitally on Marvel Unlimited and gives you the context for how Jeff entered the Marvel Universe. The surrounding issues (#1-12 of the 2018 volume) are a strong run overall if you want more Gwenpool and West Coast Avengers content.
Frequently Asked Questions
Can I read Jeff the Land Shark comics for free? Marvel Unlimited offers a free trial period that gives you access to the entire It's Jeff! Infinity Comic series. Some promotional issues, like Jeff Week #1, have been made available for free during special Marvel events. Outside of that, the comics require either a Marvel Unlimited subscription or individual purchase through comic shops or digital storefronts. Does Jeff the Land Shark talk in the comics? No. Jeff has never been given dialogue, thought bubbles, or telepathic communication in any of his comic appearances. He communicates entirely through body language, facial expressions, and the occasional sound effect. This creative choice by Kelly Thompson is central to the character's charm — readers project emotions onto Jeff based on Gurihiru's artwork, which creates a unique bond between character and audience. What is Jeff's species? Is he an actual shark? In Marvel lore, Jeff is classified as a "land shark" — a fictional species that resembles ocean-dwelling sharks but has legs and can survive on land. He's not a mutated regular shark or a shapeshifter. He was born as a land shark. The comics treat this as completely unremarkable, which is part of the humor. Nobody in the Marvel Universe questions why there's a shark walking around on tiny legs. Is Jeff a hero or a villain? Jeff occupies a unique moral space. He debuted as a minor antagonist (or at least a threat) in West Coast Avengers, but quickly became a neutral mascot character. He's been adopted by various heroes — most notably Gwenpool and Kate Bishop — and generally helps more than he hinders. In Marvel Rivals, he's classified as a support hero who heals teammates. In the comics, his "alignment" is best described as: "will eat anything, will protect friends, will not explain himself." How many It's Jeff Infinity Comic issues are there? As of mid-2026, the It's Jeff! Infinity Comic series has published over 50 issues across multiple seasons, with new issues releasing regularly on Marvel Unlimited. The series began in September 2021 and has maintained a consistent release schedule, making it one of the longest-running Infinity Comic series Marvel has produced. Why did Jeff become so popular? Several factors converged. The design is inherently meme-friendly — compact, expressive, and distinctive. Kelly Thompson's writing made him funny without relying on gimmicks. Gurihiru's art gave him an emotional range that transcended the page. The Marvel Rivals video game in December 2024 exposed him to millions of gamers who had never read a Marvel comic. And the 2024 Eisner Award gave him critical legitimacy. It's a rare case where viral popularity, commercial success, and artistic quality all aligned around the same character. Who creates Jeff's comics? Has it always been the same team? Kelly Thompson has written every Jeff-centric comic since the character's creation — she's his sole narrative voice. Daniele Di Nicuolo drew Jeff's first appearances in West Coast Avengers. Gurihiru, the Japanese art studio, has been the primary art team since the It's Jeff! solo series launched in 2021 and is responsible for the character's most recognizable visual style. The creative team has remained remarkably consistent, which is unusual in mainstream comics where characters typically cycle through multiple writers and artists. Where should a new reader start with Jeff comics? Start with It's Jeff! Infinity Comic #1 on Marvel Unlimited. The first issue is designed as a standalone introduction and requires zero prior knowledge. If you prefer print comics, It's Jeff #1: Let's Get Physical (2023) is the best entry point — it's widely available in comic shops and online retailers. For context on how Jeff entered the Marvel Universe, West Coast Avengers #7 (2019) is the origin issue.Why Jeff Matters More Than You'd Think
There's a tendency in comics discourse to treat "funny" characters as lesser — as palate cleansers between the real stories, the ones with stakes and consequences and character development. Jeff the Land Shark has quietly demolished that assumption. His solo series won the same Eisner category that has honored work by Terry Pratchett, Kate Beaton, and Chip Zdarsky. His print one-shots sell out multiple printings. His digital series consistently ranks among Marvel Unlimited's most-read titles.
What Thompson and Gurihiru built with Jeff is a masterclass in visual storytelling. They proved that a character who never speaks can carry fifty issues of comics. They proved that humor and craft aren't mutually exclusive. They proved that a land shark with puppy-dog eyes can sit at the same table as Spider-Man and Captain America and not feel out of place — or rather, that feeling out of place is exactly what makes him belong.
Whether you found Jeff through a meme, a Marvel Rivals clip, or a friend who wouldn't stop talking about the shark comic they read at 2 AM — the door is wide open. The comics are short, the subscription is cheap, and the little purple shark is waiting. He won't say hello. He'll just stare at you with those enormous eyes, and somehow, you'll understand everything.
