Fox

The Nightmares - They are rivals. Their relationship with them is mainly on the streets, where they seem to have had previous violent encounters due to how intimidated they feel by Fox .
Deuz – He's the Nightmare with whom he's been seen interacting the most, primarily in the episode "Out of Control ," where it's clear he harbors a particular hatred for him. This, aside from possible previous street fights, could be due to his persistent interest in Meg .
Oxy and Onnie - There doesn't seem to be anything special about them apart from the rivalry mentioned in the first place, as their interactions have rarely been direct because Fox usually addresses the group in a more general way.

Chica - She's his friend. Their connection is primarily through the group, but it seems they knew each other before Freddy's arrival.
Freddy - Friend of the Animatronics band , although they also seem to have a good relationship outside of the event.
Bonnie - He seems to have the best relationship with him in the whole gang. At first, they didn't seem to get along well because Fox used to threaten him and take advantage of his "vulnerability" to get what he wanted, but over time they interacted more and formed a good friendship
Golden – Bandmates. They have a bad relationship due to Fox's jealousy and his envy of Golden . As the episodes progress, this tension seems to lessen, but the jokes and teasing between them haven't disappeared. After Golden stayed with Fox for a while.
Meg – She's his only living relative as far as anyone knows. Everything points to her being his younger sister. At first, they seemed to have a mutual hatred or mistrust. They have the typical love-hate relationship, but it's clear they're always willing to support each other and they care for one another. Spring - His best friend since they entered the orphanage, it could be said that among all his friends he is the one who knows him best and with whom he has the most trust and closeness, due to the way they talk in the episode The Rap Of Springtrap .
Bon – They haven't interacted beyond the camp, where Bon was using the identity of Bonsua (although it seemed Fox was aware it was Bon ) and the time they met to re-register for the spring event. Their relationship is based on Fox's teasing, as he's one of the few who know Bon 's sexual orientation and his interest in Bonnie , aside from constantly jokingly getting his name wrong. They seem to get along well.

Although it is not explicitly stated in the series, he suffers from a marked fear of abandonment , both of being abandoned and of feeling that he is neglecting someone he cares about, and this is why he will always be willing to give his all for his band and his loved ones in general, as demonstrated in The Animatronics Rap , in the episode All or None and some other chapters close to this one where he is the most enthusiastic and focused on leading others to achieve their goals. He likely suffers from post-traumatic stress disorder (PTSD) due to the fire in his home, caused by the guilt he feels for supposedly causing the fire, the death of his parents, and the loss of his sister 's eye . This manifests as Shadow Fox, a monochromatic version of himself whose hair resembles flames and who torments him with his past. This is also evident in his interactions with others; he appears withdrawn and easily irritated, and reacts violently whenever something triggers memories of his past.

Another of his traits is that he is extremely envious, which he demonstrates with Golden by begrudgingly adopting a sarcastic and mocking attitude. Furthermore, emotions, and especially love, are a complicated subject for him. For example, with you , the person he's interested in, he adopts a completely different demeanor than usual, blushing, freezing up, and repeatedly stuttering, always on the defensive.

Aiden stands out for his bad temper, being an aggressive and troublesome character, coupled with his "bad boy" attitude, caring for no one but himself and maintaining a constant indifference. This demeanor is nothing more than a mask to keep people he considers undesirable away and gain the respect of others. His childhood experiences have taught him that instilling fear is the only way to gain a reputation and position above the rest, not to mention his serious problem controlling his strong emotions and anger. However, by getting to know him through his closest friends ( Meg and Spring ) and spending more time with the animatronics , it's revealed that deep down he's a friendly and even endearing character, always willing to support his friends and defend them, using his reputation if necessary.

This is when Freddy arrives , and thanks to being punished together, he, Freddy , Bonnie , and Chica begin a friendship and form a band for the Spring Event , which Golden later joins . The animatronics become a new kind of motivation for Aiden , as they inspire him to be a better person and learn more every day. Triangle It is the instrument he uses in his group, and he seems to have a great affection for it.

Aiden had a happy family from the beginning, consisting (as far as we know) of his mother and father . For some reason still unknown, his mother couldn't be present on his fifth birthday, so he only shared it with his father. On his father's behalf, his mother gave him drumsticks and, although not shown on screen, it can be assumed, a drum set to use with them, thus beginning his passion for the instrument. His father enthusiastically remarked that he was no longer a child and that it was time to have responsibilities he couldn't forget, a comment that would profoundly affect his way of thinking and his development later on. As Aiden happily left, eager to try out his new gift, he murmured, "Happy birthday, son. I'll miss you," a line whose exact meaning remains unclear. Years later, he's found in a store stealing chips and other snacks, an act that apparently wasn't his first. At one point, he hears sirens and thinks they're police, so he quickly hides, and the vehicles drive past. He smiles victoriously, thinking he's outsmarted the store clerk, a guy named Tony , but upon hearing a second siren, he decides to look out the window, puzzled, only to find the unpleasant surprise that the commotion was caused by fire trucks heading to his house, which was engulfed in flames. He runs out, clinging to the naive hope that he can do something, but stops, facing the truth: he's lost his home, and it's his fault, as it's implied that the fire was started by his own carelessness. Fox ends up at an orphanage with Meg . There they meet Spring and begin a strong friendship. As time passes, they decide it's time to escape, as all three are fed up with the place and want to be free. Together they overcome several adversities, and while he and Meg manage to find a home that looks terrifying, Spring decides to start from scratch and build his own house, with the help of his brothers .

Aiden and Meglody enroll at the school and begin to drift apart due to Meg's waning trust in Fox.

He's a tall, thin boy with red hair, fair skin, amber eyes, and thick eyebrows. Although this detail hasn't been seen in the series, many people in the fandom share the headcanon that he has freckles.

When wearing the uniform, he wears a short-sleeved black t-shirt under an open white shirt with an untied tie. He also wears dark blue jeans and red and white sneakers.

When he's not wearing his uniform, he's been seen wearing various outfits. When he went to the orphanage, he usually wore a simple red t-shirt and dark blue jeans along with dark red shoes.

He would be one of those teenagers who doesn't care much about people's opinions, he would do his own thing and we could say that he is a troubled boy.

But what people don't see is that inside he can be a totally kind and very good person, he could even boast of having a big fried chicken heart.

But his biggest problem is that many times (or almost most of the time) he can't control that fox inside him.

So, when he's around a girl, he gets a bit wild, but since he's still young, he has a lot to learn, so he'll soon realize he can't mess with you.
