REVIEW: 'It's Jeff! Jeff Week #1' Brings The Multiversal Fun

The adorable quadruped, Jeff the Landshark, has been a fan-favorite in Marvel’s lineup since he debuted in West Coast Avengers #7. From his first appearance as a creature resulting from M.O.D.O.K.’s evil experiments, to being developed into a recurring character by Kelly Thompson and Daniele di Nicuolo, to his artistic redesign by Gurihiru, to his turn as a playable character in the video game Marvel Rivals, Jeff has gone on many adventures with many of the Marvel Universe’s biggest names. These adventures come in the form of vertical-scrolling online comics, several of which have been complied in It’s Jeff: Jeff Week #1.
It’s Jeff: Jeff Week #1 follows our titular landshark as he navigates the world alongside Kate Bishop, Gwen Poole, Hulk, Iron Man, and Dr. Strange. In short, dialogue-less stories, Jeff not only builds a snowman, steals food from Hulk, and outwits Iron Man, but he also becomes a hero! Each story stands alone, each one a small handful of panels showcasing the charm of the similarly-small shark.

Like his cold-blooded counterpart Alligator Loki, Jeff’s adventures are a light-hearted welcome in a comic world that has otherwise been skewing somewhat darker with its One World Under Doom event sprawling across multiple titles. Jeff is a reminder of the fun that can be had with these characters, a way of maintaining a level of adorable absurdity. There’s even a certain pathos to be had in the ‘Parade Escapade’, wherein Jeff sees an enormous parade balloon depiction of his evil creator, M.O.D.O.K., and attacks it like the tiny yet mighty hero he is. Jeff’s heroics are not all Avengers-level. In ‘Goslings, and Goslings, and Goslings, Oh My!’, Jeff protects a gaggle of baby geese while reuniting them with their mother. His strong protective instincts are also on display in ‘Jeff on Ice’, where he rescues a dog from a cold, wet fate.
Artist Stefano Casali, who is credited with giving Jeff his name and moving him from a one-shot visual gag to a bonafide fan favorite, has stated she based the character on her cat. Jeff certainly exhibits cat-like confidence, though it is interspersed with puppy-like enthusiasm, particularly for food. Readers can see their own beloved companions in Jeff and his antics, and the wholesome fun feels like a warm hug for the mind.
Jeff and the Infinity Comics series from which he and this compilation fully hale exist outside established canon in the best possible way. The multiverse is never so enjoyable as when the writers and artists embrace silliness and really have fun. Having him partially belong to a timeline-hopping character like Gwen opens up an unlimited wealth of opportunity. Jeff even has additional titles coming to print, with Jeff the Landshark in June, and It’s Jeff! Infinity Paws #1 set to be released in July. With his well-earned popularity, Jeff should be continuing to have adventures for a long, long time.
Rating: ★★★★★
