So far in the first season, there have been several hints that each Miraculous holder has inherited some sort of trait by their kwami’s nature.
For example:
1) Master Fu’s age and wisdom.

A typical pet turtle’s lifespan can range from 10-80 years while sea turtles have an average lifespan of 150 years. In pop culture, turtles are seen as wise, slow-moving creatures that are often burdened by the weight of the world. Hence being the protector of the Miraculous.
2) Chat Noir’s cat-like behavior:



Since the very first episode, Chat Noir has shown many animal-like characteristics ranging from night vision to reacting to certain smells and sounds. We even see him running on all fours in several scenes; however, with his black suit also comes the popular reference of bad luck. The poor cat is usually on the receiving end of hits and is more likely to be thwarted by the enemy while his companion is working on a plan.
As Adrien, his tendencies tend to disappear, but it has yet to be shown if these abilities are fully diluted outside the suit.
3) Ladybug’s Charm

Unlike the other kwami’s nature, the only known trait Ladybug has shown is her pop culture reference of offering good luck. With a move called Lucky Charm, she stops the Akuma and then uses the same object to fix all that had been broken/damaged by her enemy. (There is also the black and white vision we see during this time; however, whether or not her vision is always like this as Ladybug has yet to be proven).
As Marinette, any and all characteristics of her alter-ego nearly disappear entirely as shown by her clumsy nature and frequent bad luck. Instead; nonetheless, she does inherit the confidence she receives from becoming Ladybug and strives to make her own luck in her normal life.
This leaves our last known person:
Gabriel Agreste.

Butterflies are considered both good and bad omens in mythology and folklore. In Japan, they are thought to be the personification of a person’s soul or mind whether they be living, dying, or already dead. In the series, Le Papillon/Hawk Moth uses a person’s negative emotions to turn them into villains in order to lure out Ladybug and Chat Noir.
Now what could Gabriel possibly inherit from his kwami?

I believe, like Master Fu and unlike Ladybug and Chat Noir, Gabriel is gaining an element of the kwami’s power outside of his transformation. In this case: he can feel other’s emotions.Whether they are positive or negative, Gabriel can sense how everyone is feeling around him, giving him the advantage to play with their mentality.
Which means he can sense every emotion Adrien feels.
It’s the reason why he let him attend school; to stop the sadness. Why he gives him more freedom to go to events and hang out with friends; to feel the joy.

It’s not until his life is threatened did he realize how much his son still loves him, no matter how far they have drifted apart.
