"Are Jason Blood and Klarion actually related?"
No they are not biologically related and neither related through things like magic, adoption, ect
There is an old fan theory though that Klarion is the reincarnation of Jason's daughter that's basically been sent to tournament him for his sins
"Why does Klarion refer to Jason as Uncle Jason if they aren't related?"
Klarion simply refers to Jason as Uncle (Stated by Jason himself in the new Batman adventures) because it amuses him
Uncertain if it's the truth though but it is just something Klarion has done for other characters as well where he refers to them with a family title such as Cousin Harry (Harry Matthews)
He is from a more pilgrim type culture though so maybe it's just a habit, he doesn't do it with everyone though so. I don't really find it odd though because I grew calling certain family friend's with those kinds of titles so could just be a thing he grew up doing and it stuck
"Do Jason and Klarion keep their dynamic?"
They haven't interacted in years so technically no but apparently sometime in 2026 (or later depending on production) there will be a new The Demon series so most likely they'll bring it back
"Does Klarion have a family?"
Yes he does
-The demon 1990s he states to have a mother and father that were imprisoned for practicing magic (but wherever or not he was lying and making up a sob story in an attempt to manipulate Harry remains unknown)
-The new Batman adventures, Jason Blood states Klarion turned his parents into mice and there's a close up of Teekl which could be possibly implying Teekl ate them
-Seven soldiers Klarion he has a older sister called Beulah, a mother whose name is Charity, Mordechai is his biological father, his stepdad Ezekiel and finally Melmoth is apparently a distant relative (?)
-Zatanna and the House of Secrets, his mother is the witch queen and Klarion is the next in line for the throne, he also has an Uncle called Ezekiel too (though I'm unsure if this is a reference to seven soldiers or just a coincidence)
-Klarion 2014, he technically has a daughter who popped out from his hand, she calls him Dad too? So technically she is his daughter though this comic was really confusing 💀
"How old is Klarion actually?"
His age has never really been stated official but he is usually between 12-15 years old in most adaptations with the youngest being about 7 years old
Even when being shown to be hundreds of years old in some versions he is essentially an eternal child/teen
"Is Teekl a boy or girl?"
Teekl doesn't really have a set gender but is usually a girl in a lot of adaptations and a vast majority of people within the fandom see her as female as well
Originally she was male in the 1970s but could still transform into this woman person type form dispute being stated to being male, Teekl is also male in the seven soldiers Klarion run as well
So 99% of the time she's presented as female
"Can Klarion die?"
Depending on the version it's shown that he can die because his been killed around four times in different comics
it's only in young justice I believe in which he is stated to be unable to die while in other versions it's never really stated
"is Klarion a villain or a hero?"
He is considered chaotic neutral, usually he does serve as an antagonist though in more recent years he has become more of whatever the writers feel like doing despite originally being a villain so he's been both part of different villain organization and hero organisations across the comics
Bonus Klarion information!
All of Klarion's voice actors so far: Stephen Wolfie (The New Batman Adventures), Tara Strong (Cartoon monsoon), Pablo Thiel (DC Universe Online), Thom Adcox-Hernandez (Young Justice, Young Justice Legacy, Lego DC Super-Villains) Noel Fisher (Justice League Action)
Klarion first appeared March 1973, issue 7 of the demon by Jack Kirby
Since his first ever appearance he has been a fan favorite with it possibly being the reason why he got more appearances because since his first appearance people apparently sent multiple fan letters though only a few were ever actually published
Klarion has a female version called Klarienne
In Jimmy Olsen's SuperCyclopedia Klarion is somewhere on the trans spectrum using they/them pronouns for this version
He is a Star Trek fan
Klarion loves sweets!! On multiple occasions throughout multiple different series he is shown eating them dating all the way back the original demon series where he is often seen eating cakes
His favorite icecream flavor is strawberry as shown by the demon within episode from the new Batman adventures
