The Flerken[1] (also called Flerkens[2] as plural) are alien creatures resembling Earth's cats in appearance and behavior. They reproduce by laying up to 117 eggs and possess many tentacles that can extend from their mouths. Their bodies also hold pocket realities, bubbles of space and time that exist in other worlds.[1]



Captain Marvel's pet cat Chewie was a Flerken, but she was unaware of that fact. She came to learn this years after having Chewie, in a space adventure during which Chewie laid eggs.[3]

An abandoned laboratory hidden beneath the Ravencroft Institute contained a taxidermied Flerken, indicating visitations to Earth prior to Chewie's arrival.[4]

The Collector had a Flerken in his museum, and has mentioned that the species has now become common enough to be considered "a space-dime a dozen throughout the galaxy."[5]


The Kree have launched a Flerken breeding program, seeding the creatures on inhabited worlds where they were adopted as pets because of their cuteness. The Kree then took control of the Flerkens with a signal beacon, directing them to attack the native species.[6] The plan was foiled by Captain Marvel and the Guardians of the Galaxy, after which Carol tasked the Guardians with relocating all revealed flerkens on Earth to their new homeworld.[7]


A flerken named Goose was brought to Earth by Mar-Vell and lived with her while looking like a normal Earth cat. After Mar-Vell's death, Goose was left alone in the Project P.E.G.A.S.U.S. Facility until she met Nick Fury and Carol Danvers six years later. Fury took a liking to Goose, who snuck aboard the airplane that they used to escape from the base.[8]

A Flerken unleashing her tentacles

Pocket Dimensions: The species are said to be able to store entire universes within their mouths, within which they can access and store a great many things to draw upon at will.

  • Tentacle Protrusion: Flerken possess a mess of tendrils kept within their mouths. They can use these for support and offensive tactics.
  • Nested Mouths: Sprouted tendrils host a nest of fanged and ravenous maws which can bite down on and gobble up just about anything.
  • Dimensional Travel: The sub-spaces within themselves can also be used as a means of instantaneous transportation; the process can be messy to say the least, however.[1]
    • At least in Earth-18157 all Flerkens share access to the same pocket dimension. If one survives being swallowed by a Flerken and is able to find their way back, the exit point can be from any Flerken anywhere.[6]
  • Toxicity: In the Earth-199999 reality, a scratch from a Flerken causes severe tissue damage to humanoids, as Nick Fury found out when a claw swipe from Goose to his left eye resulted in scarring and permanent loss of function.[8]


  • Human intellect: Able to understand cognitive conversation.
  • Overwhelming cuteness[6]


Alien aspects are accessed through their oral cavity. If somehow muzzled, a Flerken is as helpless as an Earth cat.[8]
