Kay looks rather normal for a Pichu. Other than a slight notch in her ear, she's pretty indistinguishable. Maybe she'll take up wearing a bandanna or something in the future?

Let's get it out of the way: Kay is not, and never will be, a submissive Pokémon. Quite the contrary, Kay is someone who holds her ground, venturing forth into the unknown with a kind of boldness that would make others cower. While fears rest within her heart, Kay is someone who doesn't like to sit on her laurels; indeed, she often prefers to challenge herself and experience new things and go new places. Confidence radiates around her wherever she goes, and it's not bravado, either; she is outgoing and emotional in the greatest sense, a heart on her sleeve kind of gal, and yet that only strengthens the case that her bravery comes from a genuine place. Insecurity and doubt could plague her, but she knows how to deal with it when it crops up.

It's easy to think with someone as bold as Kay that she could be harsh and unfair, but in reality Kay is also balanced out by being very much kind-hearted. Kay places others before herself habitually, and not only that but finds herself unable to ignore calls for help when they happen. To put it simply, Kay likes being the hero, not for the fame and the fortune but instead for the thrill of the adventure as well as the safety of others around her. She genuinely cares about the causes that she works for and she has a strong moral model that she builds her life around, and it's plainly obvious in the way she behaves. Every smile when she rescues someone from danger is a real one.

That isn't to say that Kay exists without her faults. While the boldness does not morph her into someone aggressive, it does make her stubborn and often rigid in the way she behaves. While not a leader and not someone who desires to be leader, she still can be a little bossy, especially when she believes someone else is making a mistake. She veers dangerously close to "my way or the highway" in some situations and can be awfully judgmental of others' decisions if they are not in line with her own. In addition, she does not like the idea of Pokémon helping others for their own gain and can come off as preachy and soapboxy in regard to her own moral code without considering that others' may work better for them. Her moral code, while certainly reasonable, is not the only right one that can be followed.

Ultimately, Kay is still growing and it's clear in the way she behaves. She learns and she's receptive to learning and she can definitely admit when she's been wrong, but it may take quite a lot of prodding to get her there. In addition, she's also oblivious to her own hypocrisy; certainly while she helps others for their sake primarily, she is not one to deny a reward when it's given to her, and she enjoys gorging herself on food and can even be selfish when it comes to giving it out. She is willing to give her life for yours if the situation is that dire no matter what allegiance you may have (and indeed, she believes in giving everyone a chance and the grudges she holds are minor at best), but suggesting that she share her stashes of food with you if you're not a close friend is a big no-no. In addition, she can be close-minded about her ideas and although she will admit she's wrong, it'll take a lot of convincing to change her mind.

Overall, Kay is a bold and kind-hearted Pokémon who still displays some of the teenage immaturity that comes with the stage in her life that she's at. She has good intentions and it's clear she cares about the causes she's passionate about, but she still hasn't considered nuance in her worldview and it can lead to her clashing with others. She's not conflict averse, but she definitely prefers to avoid unnecessary conflict, which is why it would do her well in the future to learn to pick her battles.

Not every breeding pair wants to stick it through the whole way. This turned out to be the case for Kay and her older brother, Sebastian. Their mother and father at first appeared to be very much in love, inseparable even; they were two of the most cuddly Pikachu, and no one would have questioned if they just sat around and had kids for the rest of their lives. But as luck would have it, eventually childcare became overwhelming for them when Kay was born.

Sebastian already proved to be a pawful. Although different from Kay in disposition in that he was calmer, more rational, and gentle, he still had wild blood within him and often ran away from their mother and father, leaving them to chase after him in order to ensure his safety. After all, they wouldn't want him to wander into a neighboring country and to get captured and imprisoned for that very reason. Although Sebastian learned to behave more as he grew older, the early strain that taking care of a child provided the two Pikachu indicated to them that neither of them were properly ready, really, to have children.

This became more apparent when Kay was born. The parents didn't even want her to begin with; she'd been an accident, unlike Sebastian, who was already too much for them to handle. Said parents gave it a valiant effort at first, but as their relationship continued to strain and Kay proved to be even harder to take care of due to her propensity to run not dissolving with age, the parents made what was probably their worst decision: they ran.

To be fair, it was likely that they would've thrown Sebastian and Kay into conflict anyway as their relationship had been growing more and more tumultuous, and those who knew them would suggest that they're no longer a couple and it was any wonder anyone thought that they were made for each other. Thankfully enough, Sebastian grew enough that he was able to take care of himself, and he hardly begrudged their parents for leaving.

Kay, on the other hand, didn't fare as well.

Acting out, she found herself in the midst of conflict after conflict with Pokémon around her age, not the least of which being a Poochyena who wound up biting a portion out of her ear. The incredible pain forced Sebastian to isolate Kay from the other Pokémon in order to nurse her to health, and although he was far from a parent and didn't know how to be one, he tried his best to support his sister and be there where their parents couldn't. Comforting and becoming a bit of a rock within her life, she grew clingy to him approaching her more teenage years, even after he'd evolved and grown into a Pikachu himself and would be expected to earn himself a job.

Unfortunately, Kay being so heavily dependent on Sebastian meant that it was difficult for the two of them to go anywhere separately. Separation anxiety attacked Kay hard whenever she was too far away from him, and as for Sebastian, he had a hard time doing anything other than coddling her and keeping her close to the nest. While Sebastian was far from the most ambitious Pokémon, this kept him from truly growing up and socializing and perhaps becoming a true civilian. He wanted to run a shop of his own, but with Kay needing so much from him he had no choice but to try to scrape by with her.

Eventually, Kay caught onto the trouble that she was proving to be to Sebastian and, upon his evolution to Raichu, decided it was time for her to seek an evolution of her own. Although she doubted she would be a Pikachu any time soon, she definitely wouldn't become one leeching off of him, no matter how kind he'd been. She decided she wanted to get better and improve her life - and, conversely, she wanted to improve the lives of others around her. It was in this that she split off from him, allowing him to manage his own shop while she looked into work that she could do for herself.

It was no surprise that the life of an Explorer and a Rescuer appealed to her so much. At the time, she'd been too young to enroll for it; but that didn't prevent her from training for it. She went adventuring on her own as well as speaking to other Explorers, until finally she hit that sweet spot of an age in which she finally dove into headfirst. It is now that this part of her story begins, as she embarks on adventures and meets new faces and paves out a path for ages to come.
