Homebrew Flerken Species Details

In the comics (Marvel Comics), the Flerken are a race of aliens that resemble Earth's cats, lay eggs, and possess multiple tentacles that can extend from their mouths, which hold pocket dimensions inside of them.This pocket dimension allows them to swallow objects for protection and regurgitate them later on, even being capable of storing things as powerful as the Tesseract. In these pocket dimensions, Flerken store large tentacles that they can deploy at will from their mouths to attack enemies and help swallow large objects.

Mar-Vell owned a Flerken named Goose, whom she had taken with her on Earth during her undercover mission. After her owner died, Goose lived inside the Joint NASA USAF Facility for several years, until she was reunited with Carol Danvers, one of the few people she liked. Goose traveled with Danvers to the Rambeau Residence and then to Mar-Vell's Laboratory, where she fought some Kree soldiers using her tentacles and swallowed the Tesseract. 

The Flerken are alien creatures resembling cats. 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.

The Beast Within

Powers

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.
• 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.

Abilities

Human intellect: Able to understand cognitive conversation.

Weaknesses

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

Similar and Diverse

Shifters are similar to the house cat in height and build but are typically more lithe and flexible. Their facial features have an intelligent cast.

The Journey Yet to Come

 Dwindling: 118 known living specimens.

Although it is known that a Flerken can lay up to 117 eggs in one clutch it is unlikely that they will survive.

Flerken Names

Flerken have no language of their own and often live in blended communities, this is done mostly so that they can hide within society, they are hunted viciously by many space faring races. Their names typically overlap with the names of other cultures in their region. Many Flerken prefer to keep their personal names for their friends and use “wandering names” with strangers. These are usually tied to a physical or personality trait.

Flerken Names: Goose, Custard, Spot, Oreo, Night, Denali, Orange, Tiger, Tigger, Elle, Chewie, etc...

Flerken Traits

Your Flerken character has the following traits.

Age

A Flerken ages in a similar manner to the common house cat, however once they have met adulthood they stop aging completely. Most Flerken only pass from disease, eating something it shouldn't, or being hunted and killed by other races.

Alignment

Flerkin tend toward neutrality, being more focused on survival than concepts of good and evil. A love of personal freedom can drive shifters toward chaotic alignments.

Size

Your size is Small. 

Speed

Your base walking speed is 50 feet.

Darkvision

You have superior vision in dark and dim conditions. You can see in dim light within 120 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.

Shifting

As a bonus action, you can assume a more humanoid appearance. This transformation lasts for 1 hour, until you die, or until you revert to your normal appearance as a bonus action. When you shift, you gain temporary hit points equal to your level + your Constitution modifier (minimum of 1 temporary hit point). 

Once you shift, you can’t do so again until you finish a short or long rest.

Your appearance and displayed race can vary, but you will generally appear incredibly short, so for taller races it would be wise to choose the appearance of a child.   

Languages

You can speak, read, and write Common. You can also speak telepathically with someone that you are well acquainted with. 

Subrace

As a Flerken you appear like a normal housecat, there can be some variation in breed. DM discretion on specific breed advantages and draw-backs.
