Okay, I missed a few with my characters!

This makes far too much sense and Rickard Gavin cannot make sense so jossing for that reason alone. In all seriousness, I'm not sure I can even imagine him as a child. I tend to think of him as more of an embodiment of weirdness than an actual character most of the time.

This is probably true. Anyone can write for the fandom, though, so I've sort of taken to assuming all of these are canon by default unless someone says otherwise.

It's possible. I don't have deaths planned for any of the remaining members, though, so the future is probably entirely open to alteration.

So, apologies that none of these answers really say anything at all.

And I think I'm going to be a jerk and add another ask even though I didn't answer anyone else's because I am curious:

♫ - Any of my characters

Claire: Jossed
Esprit:Kind of an obvious choice, but it works.
Jet: Semi-confirmed. He's fixed it now.

Seems likely.

Confirmed. And it gets even weirder than just a different region sometimes.

Confirmed.

Also, more asks:

∇ - Elise
♫ - Rawst
☠ - Straw
★ - Aurora
☁ - Nicole
▼ - Jet
☁ - Esprit

I don't really know image songs and what they are, but I listen to a few songs and their general vibes remind of of them, so I've got a few:

Maria: https://www.youtube.com/watch?v=z6_ikWlJu_0

Francis: (would probably unironically like this song. Plus, I imagine him doing the dance and I find it funny) https://www.youtube.com/watch?v=uxpDa-c-4Mc

Because I am similarly bored and curious:

♫-Joseph
♫-Samantha
♫-Mimmy
♫-Kirsten
♫-Alys
♫-Munn

Gonna suggest that it might be better to limit the number of image songs/leitmotifs per ask since they can be kinda hard to answer.

♫ - Maggie

Soleanna Castle Town from Sonic '06.

■ - Grayson

Has a special Robin hood for sleeping in his nest.

∇ - Elise

Elise will end up retiring to a quiet cottage in the Sinnoh North near Snowpoint, with or without Vierr.

♫ - Rawst

Gruntilda's Lair

☠ - Straw

If Straw ever got the chance to kill Jet for murdering Taylor, he'd take it without hesitation.

▼ - Jet

Jet liked to raise Pidove.

☁ - Esprit

Esprit is depicted as having some sort of creepy crush on Elise.

♫-Maria

Fly in the Freedom from SA2 because she's a treasure hunter who wishes for freedom from her mother, who was also impulsive enough to raft the thousands of miles between Unova and Almia to get away from her.

♫-Kirsten

Pleather for Breakfast, of course. :P

Outstanding list:

♥ - Fuuma
♫ - RP!Tagg
▼ - Sol (the human)
♡ - Crochet

♫-Tori
♫-Joseph
♫-Samantha
♫-Mimmy
♫-Alys
♫-Munn

I am here to confirm and deny things and possibly ask things as well!

♦ - Rebecca
"Rebecca has on at least one occasion thrown a dart at a colored wheel then dyed her hair that color."

She absolutely has. That is generally how she usually chooses, unless it is a special occasion. Side note, Rebecca is very good at throwing darts.

▼ - Rebecca: "When she was a kid, she liked to play "boop the snoot" with Oshawotts."

When she was a kid, Rebecca played boop the snoot with everyone. Humans, pokemon, whatever. She was super playful and had no sense of personal space.

☠ - Rebecca
"Rebecca has managed to use her knife in self-defense at least once."

Um, probably! She mostly uses it to cook, but she can fight with it.

☮ - Rebecca
"Rebecca wonders if her and Tagg could be closer friends since she's noticed how he's changed over the past four going on five years."

Hmmm, maybe? I would actually like to explore that connection, especially since i've gone back and looked at some of their interactions pre-hitatus.

♡ - Rebecca
"Rebecca's the kind of person to show her love in dramatic ways."

I've been stuck on this head canon for like 10 minutes, and I can't decide if it's true or false....Yeah I'm gonna come back to this one.

☯ - Rebecca
"Aside from the fact that she uses knives, Rebecca loves collecting them as well."

Confirmed! Somewhere in her hammerspace bag, Rebecca has at least 3 sets of kitchen knives, as well as fancy pocket knives and throwing daggers. She had a broadsword at one point (it was given to her as a gift at age 9), but she couldn't lift it off of the ground and decided to give it to Gamer. So, now I have just made it canon that Gamer has a broadsword. XD

Thank you to Tagg and Cortus for the head canon suggestions! And I shall come up with questions and head canons for others later maybe!

Not sure how much I can really joss/confirm fandom asks, come to think of it.  But...

Blitz:  This would not surprise me

Tori:  Pfffft

Not sure how to respond to an image song thing either.  But I like them :p

And because I think this got forgotten: 

ൠ - Larxene

Larxene is really good at using Double Team.

♫ - Zeal

★ - Aurora

Aurora still looks harshly at the time that Crescent went "nice guy" on Borealis.

♫-Lane

A song about breaking free of his mother's chains with the help of the J-Team.

♫-Samantha

I could see it.

Crochet: Confirmed.

Forecaster: Also confirmed, she doesn't like constant weather fluctuations, especially after having to deal with the screwed up weather during the first Hoenn arc.

I say, thread, rise from your slumber!

Both confirmed, though the Psyelle one would probably need a confirmation from Psyche too.

Apart from occasionally reminding her of Pianis, no. Jossed.

Grayson: <Holy appropriate setting!>
Confirmed.

I won't bother confirming or deconfirming the musical ones, because those are open to interpretation.

♥ - Fuuma
Fuuma has considered adopting a child.

▼ - Sol (the human)
During her childhood Sol's tribe came into many conflicts with local Simisage and Simisear clans, who believed that humans should not be part of their civilization.

☼ - Glöckchen

✿ (or ♡, if uncomfortable with that) - Your choice of any canon ship
✿ (or ♡, as above) - Your choice of any non-canon ship
ൠ - Your choice of any Eeveelution from the RP

Oh, looks like I missed this.

If I ever get my motivation back, this should be answered soon IRP one way or the other, with that whole thing sorta being picked up again.

(Also, would it be possible to add "ൠ - Any of my characters" again? Maybe even as a permanent thing, like, "Oh, hey, if you want, I would be happy to hear anything at all you might have to say about any of my characters!" Or something like that, I guess.)
