Kingston's was losing his team ;u; aa I wanna draw a comic about it but I'll have to add that idea to the LONG list of ideas I have to draw!!
When he found out it was just... he wasn't motivated to do anything for a long time, not eating well not taking care of himself. Than was looking after him, literally having to possess his body to make him eat sometimes or like exercise bc he was also recovering from severe injuries OTL and one day Than just decides to let K talk to Suzu... (the person Than was before it was a sword) and they had a long conversation and K asks her why she's never talked to him before like this even though he could've... really used her guidance and she tells him "it is at our lowest when we are open to the greatest change."

I can't answer for all my ocs but I love this qn QWQ

Oho, loaded question 👀.
She was told something unexpected at the age of 16, after finishing her journey through Hoenn, which completely broke her morale and gave her a crisis.
She closed off and mood became extremely sour. Because if this, when she began her journey through Unova she was...a short fuse.
Taking out her pent up anger and resentment in those who annoyed her.
This was at her lowest and most neurotic.
She had to be put in her place to calm down and be reminded to not throw a temper tantrum without realizing the consequences of her actions, and what was to be at stake.

Unfortunately...after some reflection at the end of her journey, she closed off even more, but became better at pretending she was just fine.

For Briar it definitely was when she moved to Unova after disbanding Team Flare. For her, being part of Team Flare was not a bad experience per se, what was really awful for her was what happened after it no longer existed.

When she moved to Castelia City, she stopped doing scientific work and had no money to afford the luxuries she was used to with Lysandre. And that, too, her fiancé had just died for his ideals of a beautiful world that was never going to work. At this point in her life, she blamed herself for the downfall of Team Flare, since she was the Commander, she blamed herself for "not working hard enough", for "not trying all the options", and specially for letting Lysandre die.

In Unova she kept a low profile because she was also being chased by the Interpol, and started working at a theater; she always loved the arts but could never dedicated her life to them to favor her scientific career, but since she was now trying to start a life from 0 and as far away from science as possible (so people don't suspect her), she became a performer. But still, even if she was doing what she always wanted to do, being so depressed made her unable to enjoy any moment of this.

Overcoming this took her years, but it started when she moved to Galar when she agreed to help Rose on some scientific project he had. Her story in Galar is basically her journey through a grief she kept bottled up for years, alongside her finally coming to terms with the downfall of Team Flare, including (but not exclusive to) finding out that she wasn't the one to blame for Lysandre's decisions, among other things.

It is true that Briar overcoming all of this was done thanks to her own efforts, but she knows she couldn't have taken the first step without Rose and Oleana, and she always thinks they saved her life.

Elio's lowest point is basically what I talked about in certain previous asks: the <Emotionally-Stunted Phase> of his childhood - which he doesn't like being brought up in conversation and does his best to fabricate something to replace it.

It took him meeting <Mephisto the Darkrai> - who would later become his, and later - his younger siblings' foster father, and doing his best in aiding in his recovery by infiltrating the [Dreams] of New Tork's denizens, defeating their [Nightmares] - thus gaining their crystallized essence, and learning a variety of life lessons from all the dreams that he passively experienced, to have the epiphany that led to his establishment of an emotional foundation: the correct step towards the normalcy Elio had unknowingly desired for such a long time.

Regardless, his overcoming of that low point doesn't mean he won't dwell on it every now and again; he still retains a habit of convincing himself that his feelings are his own, not a by-product of meeting everyone else's expectations, and he's still human like everyone else around him.
