Mafioso AU

🧠 Communication

In addition to body language, they use sounds and vibrations.

This goes perfectly with the famous:

Knock knock knock

Chance on the submarine's hull.

To humans, it's just someone hitting metal.

For Chance, it could be practically:

"I'm here. Are you there?"

🌑 Rare item

This species is very rare.

This also explains the possibility that Chance is one of the last known individuals.

There may be others, but they are scattered across extremely distant oceanic regions, making encounters between them very difficult.

This makes the connection with Mafioso even more complicated, because Chance may not have many individuals of his own kind around.

🫀 And the biggest detail

This species doesn't understand love in exactly the same way humans do.

For them, connection means presence, care, and permanence.

So Chance initially doesn't understand why Mafioso needs to leave.

In his mind:

"If we found each other, why should we separate?"

🦈 - Chance's Species

🌊 Habitat

They live mainly in deep, dimly lit regions of the ocean, although some individuals frequent shallower waters.

They are excellent swimmers and can move silently, using the darkness and murky water as protection.

🫧 Breathing

They have gills, so they depend on water to breathe normally.

Outside of it, they can survive for a few minutes thanks to a special adaptation, but not indefinitely. The longer they remain out of the water, the harder it becomes to breathe.

This explains why Chance tries to prolong meetings with Mafioso even when he should be returning to the water. Biologically, a terrible decision. Emotionally, completely consistent with him.

🐚 Intelligence

The species is extremely intelligent and possesses the ability to:

learning languages;

to recognize individuals;

memorize routes;

to understand gestures;

imitate sounds;

Develop complex social bonds.

Chance, specifically, learns a lot by observing humans.

💙 Bond between individuals

This is one of the most important characteristics of the species.

When they find someone with whom they form a deep bond, they tend to stay close for long periods of time.

They demonstrate affection through:

physical contact;

to accompany the other;

protection;

exchange of objects;

sounds;

gifts;

Constant search for companionship.

Therefore, Chance initially interprets Mafioso as someone who could be his permanent partner.

🎁 Gifts

They have a habit of offering objects that they consider interesting or valuable.

Not necessarily things that are beautiful to humans.

A rare shell? A gift.

A piece of metal from a shipwreck? A gift.

Something completely rusted that nobody knows where it came from? A very important gift.

And when they receive something back, they usually keep it carefully.

Gray skin, gray hair, partly long, partly short. Yellow eyes, 26 years old and 1.70 meters tall except for the tail which is half a meter long, fins between the fingers, gills on the neck and 'ears' that look like fins. The tail is smooth, without scales, very flexible, with small fins on the sides (between which there is a discreet reproductive slit that remains closed), and a larger fin on the back of the tail as well. The end of the tail is wide (It has no scales, the tail is like shark skin. No scales, just smooth skin.) Pointed teeth like those of sharks.

A mobster is the type of person who doesn't waste a reaction. He operates in well-controlled layers:
External: calm, focused, speaks little.
Interior: constant risk monitoring, automatic scenario calculation.
Under pressure: he doesn't panic quickly, but when something breaks the logic... he fixates on it.
He is not cold in an empty sense. He is emotionally economical. Everything he feels goes through a filtering process before becoming action. Key traits:
Extreme observer (perceives patterns before perceiving emotions)
high tolerance for isolation (open sea, silence, routine)
Non-explosive irritation, but definitive when it breaks trust or logic.
Dangerous curiosity (he doesn't run from the unknown, he overanalyzes)
His weakness is not fear.
There's too much interest in something that shouldn't be investigated so thoroughly.
He has yellow skin, short black hair, a shadow covering half of his face from his eyes upwards, submarine or scientist clothing, and a black fedora hat with a black band and thin light brown stripes on the fedora.
34 years old and 1.90 meters tall

Mafioso is a marine explorer who meets Chance, a creature of the ocean, after seeing him pass by the window of his submarine. The two develop a strong bond: Chance learns about the human world and shows affection with gifts and closeness, while Mafioso learns to reciprocate without trying to change who Chance is.

The conflict arises because they belong to different worlds. Chance would like to live alongside him forever, but realizes he can't simply abandon his aquatic nature. Thus, the AU has two endings: a sad one, in which Chance walks away despite missing him, and a bittersweet one, in which the two find a way to remain close without either having to stop being who they are.
