In the sprawling, action-packed roster of Marvel Rivals, where iconic heroes and formidable villains clash, one character has unexpectedly stolen the spotlight and captured the hearts of players: Jeff the Land Shark.
This adorable, mischievous land shark stands out as the game’s most unlikely—and undoubtedly most beloved—breakout star. But how did a finned quadruped become a playable hero in one of 2025’s hottest team shooters?
Comic Book Origins: From MODOK’s Creation to Marvel Mascot
Jeff the Land Shark’s journey to stardom began subtly in the pages of West Coast Avengers #7 (2019). Created by writer Kelly Thompson and artist Daniele Di Nicuolo, Jeff was initially just one of many “land sharks” engineered by the villainous MODOK Superior, intended to wreak havoc on Los Angeles. However, Jeff quickly distinguished himself from his more ferocious brethren. His undeniable cuteness and surprising reluctance for villainy caught the eye of the fourth-wall-breaking anti-hero, Gwenpool, who promptly adopted him as her pet.
From that moment on, Jeff’s star began to rise. He became a charming fixture in the wider Marvel Universe, forming bonds with various heroes, including the skilled archer Kate Bishop, and even spending time with the irreverent Deadpool and the monster hunter Elsa Bloodstone.
His popularity truly exploded with his own digital comic series, It’s Jeff!, available on Marvel Unlimited, which beautifully showcased his endearing antics and unique personality. Fueling his meteoric ascent, Jeff is even set to headline his first print comic series in June 2025, a testament to his burgeoning fandom.

Jeff in Marvel Rivals: A Strategist with a Secret Bite
In Marvel Rivals, Jeff the Land Shark isn’t just a charming cameo; he’s a fully playable Strategist class hero, designed to provide crucial support and disruption on the battlefield. Despite his 1-star difficulty rating and seemingly innocent, puppy-like appearance, Jeff is a formidable force, capable of both healing allies and turning the tide of battle with unexpected utility.
His unique abilities include:
- Joyful Splash: Jeff’s primary attack, a short-range healing splash that can restore health to multiple allies.
- Aqua Burst: A secondary attack that fires high-speed water projectiles at enemies, dealing surprising damage.
- It’s Jeff! (Ultimate): This signature ability sees Jeff dive underground, then resurface to swallow both nearby foes and allies. He can then spit them out strategically, potentially eliminating weaker enemies by launching them off the map or repositioning high-priority targets.
- Hide and Seek: Jeff submerges himself, leaving only his dorsal fin visible. This grants him increased movement speed, self-healing, and the ability to wall-crawl, allowing for unique flank routes and escapes.
- Healing Bubble: Jeff spits out a healing bubble that, when collected, boosts and heals teammates, while also disrupting and launching nearby enemies.
- Oblivious Cuteness (Passive): This passive ability reduces damage Jeff takes from critical hits, making him deceptively resilient despite his smaller stature and apparent fragility.
Furthermore, Jeff excels in Team-Up synergies. When paired with Luna Snow, he can unleash the “Frozen Spitball” ability, infusing his Aqua Burst with ice energy to slow down enemies. With Groot, Jeff and Rocket Raccoon can ride on Groot’s shoulders, gaining damage reduction with the “New Friends” combo, adding layers of strategy and delightful chaos to his playstyle.
The Irresistible Charm: Why Fans Adore Jeff
Jeff’s widespread appeal stems from a powerful combination of his irresistible cuteness and his surprisingly impactful utility. In the comics, his wild antics have cemented his status as a fan favorite – from attempting to steal Captain America’s shield to famously eating an Infinity Gauntlet, and even temporarily bonding with a symbiote.
In Marvel Rivals, he translates this lovable unpredictability into gameplay. He’s a reliable support powerhouse, but also a wildcard capable of single-handedly altering the course of a match with his unique ultimate ability.
Jeff the Land Shark’s journey from a whimsical background gag to a full-fledged Marvel mascot is a testament to the power of fan engagement and character design. Whether players are utilizing his healing bubbles, masterfully swallowing enemies, or simply reveling in his charming antics, Jeff brings a unique blend of joy—and tactical chaos—to every match in Marvel Rivals, solidifying his place as one of the game’s most memorable characters.
