Heres some background detail for each version of each character:

Riu The Riolu:
Riu The Riolu wasnt a really a fursona, yet hes importend to count in aswell. Back in late 2015 i created my first Twitter account. Before someone asks, back then it was legal to have a Twitter account without any restrictions even when you were 11 years old. I was 12 myself back then and followed a lot of Pokemon artist, mainly Riolu and Lucario stuff even tho i didnt really knew what Pokemon was. I mean i recieved White 2 on release but i was struggling at Micas Gym and never could defeat her until around 2017 but honestly can you blame a 9 years old child at struggling on Pokemon?
Anyways i knew what Pokemon was but not really much, yet i really liked Lucarios design and especially Riolu since i already had a strong interest in the topic of anthropomorphic animals for multiple years, so i "made" Riolu to represent me on Twitter around from that time since i got framed in french for using a random Len Kagamine picture as icon, but since i throught i should be more different than some common Riolu i gave myself the name Riu The Riolu and had Fire Aura (creative i know i know).
Sadly, i lost all kind of drawings when i was Riu since it were a lot and at some i was pretty proud but they were traced but atleast i always asked for premission to trace so yeah its something.
As you read, Riu kinda was like a Fursona even tho i didnt even knew what a fursona was back then. Thats why hes Version 0 as hes the prequel of the first fursona.

Luwis The Fox:
I only got one drawing of Luwis and i did it myself. It was shortly after my 15th birthday. The reason was that one day before my birthday a new law had been released about online safity, which resulted that my 2 and a half years old Twitter account got deleted because of the requirement of proofing that im over 13 years old, which i walready was, with an ID card which i legaly wasnt able to even own since you only recieved one when you turned 16. When i started a new account i found many different kinds of artist who also drew all kinds of anthropomorphic animals, which i liked. Since i already had been introduced to the topic of the Furry Fandom from a friend who disliked furries a lot, i already knew what i was going into so i drew a random animal with pointy ears and a long fluffy tail, which was a fox without me realising it. I just used the colours i liked and which i even had in hand and it was Pink, Cyan and Green.
I still got the first drawing of Luwis saved on my PC.

Luwis Khaski:
Half a year later i changed Luwis The Fox because i wasnt really that happy with the design anymore, aswell as i throught he kinda looked like a very small and young child, which i wasnt really happy with in my teenager years, aswell as i won a raffle for a fullbody drawing. Since i didnt wanted to show Luwis as he was so i was thinking and drawing on Gimp and one day i came to the throught of being a dog since i was full of energy and i loved tail wags, aswell as animals with spiky ears and came to the throught "German Shepherd or Husky" and decided for the Husky since they look better with changed colours than on a german shepherd, aswell as i wanted to look more basic but not common which worked better with a husky. Since its been like 2 months where the artist waited for my refsheet for the drawing i was extremly stressed and when i finished the drawing of Luwis as a husky i throught of giving a more unique name so i just translated husky to japanese since it sounded nice. I was extremly unhappy and even mad at creating Luwis Khaski, so i wrote the artist, told them that i dont have a ref sheet, that i am sorry for the incredible wait, that i didnt manage to do a ref sheet and i dont want them to wait any longer and asked them to choose a new winner since 3 people could win but only 2 recieved a drawing while mine was wasted, which made me incredible mad at myself.

Luwis The Husky:
Months passed and i was thinking about my fursona creation and throught about how to improve him. I always was thinking of him as myself and i was incredible unhappy and hateful at myself back then, so i throught how i would be once i grow up. With grow up i was thinking of living on my own and recieving my own money and what i expected to be like when i reached that time.
In other words: My fursona turned into my expectations of myself than being me.
I throught i would be finally happy, loveable, kind, heart warming friendly, aswell as i hoped to be over 2 meters tall (thanks to my mom for being incredible small i am not that tall). The colours are choosen to be my two favorite colours, Limegreen and Magenta, aswell as i throught it would be funny if my colours would be the opposite, so they hex-code are 00ff00 and ff00ff.
Later on i realised the constand discirmination that are normal for furries. "all dogs are just weaker wolfes" "All dogs should be wolfes" "wolfes are way stronger, braver and better over all than dogs" "dogs are just naive puppets who are controlled by others" and i can go on with that for who knows how long. It started with me seeing those messages once per week up to daily up the the poin that after a full year i constandly had been tagged in both Twitter, Telegram and discord that i am just a weaker and worse wolf and that i should be a wolf because of how much better they are, while it started that furries constandly marked me at those conversations on both Discord, Telegram and Twitter. I deleted Telegram because of that and on Twitter i got marked 2 to 3 times a week for multiple months and it broke me since constandly pointing at a species with their stereotypes against their consent and refusing to stop is normal in the fandom nowadays. I mean nowadays i still get told that people think i am gay because im a fox or than im a femboy and a bottom JUST because i am a fox and way too many furries refuse to actually refuse to stop because "stop overreacting snow flake", same thing goes for "once you grow up you will be a caffee junkie like all of us adult furries" and "you are a child. You cant know REAL work and you should know you place" "Its just puberty its gone when you grow up" simply because i WAS (i repeat, i was! Im not one anymore!) a minor and not 18 yet.
This is why i changed my species and sadly the discrimination ended just because of that after some weeks afterwards but sadly the others started years later.

Luwis Miracle:
I started to be unhappy with the design of Luwis The Husky as he was more Magenta than Limegreen, even tho i wanted it the other way around, aswell as my interest in Jesters only got bigger and bigger so i gave him that thing that Jesters get mostly associated.
Aswell as i changed him to a fox because of the long fluffy tails foxes tend to have.
His characteristics also got more into a chill and relaxed type of person since i throught after all that self hating aggression disorder i would start to be very chill and relaxed once i grew up.
I am not like how i expected to be. The way Luwis is described is not how i ended to be. I am different from Luwis. Luwis is the expectations i had of myself which i didnt reached. Me and Luwis are not the same, yet similarities exist. Since Luwis 3.0 he wasnt really me anymore.
Miracle is his name as the M should be reffered to me irl as it sounds very fitting for the colours and characteristics aswell

Cylia Voixy:
The story of Cylia really is extremly long and complicated but after teasing it so much i will short it down.
When i was 7 years old, i had a dream of having a fox tail and being able to jump super high and running super fast. Since that dream i started to develope very strong interest in anthropomorphic animals, how as i said until i was 13 "animals that walk like humans and have human abilities but arnt humans but still animals but more evolved".
That one dream i expanded the story of it from that child being the so called "otherworldly animal half god" and me just a vessel to hide inside my body from the goverment who searches him for hightly detailed mass murder and torture of humans but since he looked like me he could use me to hide inside me as an alibi that i wont get punished because i was 8 years old and others can confirm it wasnt me while he used my face to commit crimes. One day he kidnapped me and my brother to save from the world destruction as on the new planet me and my brother had been kicked out from the Otherworldly Animals Half God as i watched my brother die right infront of me as i run away from the bullets. Later on the "OAHG" (i dont wanna always write the full name im sorry) gave the option to train me for survival and we shaked hands, which was indirectly a "Deal Of Kurmanshi" meaning i recieve power as i loose my control of life and life power, such as ethernal reviving as i and the contract dealer gets equaly stronger if one trains, or as in number:
If power would be describted as power i would been at 3 back then while OAHG would been at 400.000 and if i increase my power from 3 to 56 OAHG also increases the power from 400.000 to 400.053 and if multiple people would had a contract, it would go with 3 to 56, 17 to 31 and 11 to 49 which would mean +53 +14 +38 which means +105 for the Deal Maker while the deal maker has the control of the strings of death of a person so when the dealer decides to cut the strings and break the deal the person dies while the dealer keeps the power recieved.
I recieved such an amout of power that i got strong aswell as i died, yet since OAHD had the strings it constandly rebirthed me for more power for both of us i constandly started at 0 again and always raised up different power in different bodies with my soul inside. After time i realised that the souls of the other bodies i have also are seperated souls at he same time, so i freed them from as as they became their own being with their own soul while they arnt connected with each other, yet connected to me as i started to call them "souls". Over time they only got more and more as i got more and more powerful, OAHG included.
The first souls name was Draus (reference wont be told cuz of privacy) a male shadow dragon. As one decade flew away irl the time in that story i increased each dream as the story already reached over 70 years in lore. One plot of the story was that Draus had a wife who was an angeldragon and two children, Dragius, a male angeldragon and Cylia, a shadow dragon who possesed two souls. While the Souls throught it was me inside, which i actually wasnt, so the souls tried to protect her from being split into two so OAHD would stop getting more power, which failed when Cylia was 8 so her two sides were released, an incredible young female angel dragon was released who was 2 years old and hanged together with the souls since she should be taken care of and a water dragon with a shadow dragon design who was 14 years old (2 + 14 =16 : 2 = 8 for both souls).
I liked the idea of her design so incredible much that i wanted to keep her once i finished the story or when i stopped continueing the story, which happened after 13 years when i first started it.
I finished her design when on paper i was still 15 years old and named her Cylia Voixy

Thats the really weird, long and huge story of Cylias creation. Yes it is shorted up as i only said the importend topics to that.

The Beta design is a failure tho. I asked a friend for help for finding an artist who agrees to a ref sheet of her and the artist i got recommend was a horrible expierence sadly. Ignoring that i waited 3 months of constand ignoring my messages while playing fortnite non stop i threatened them to recieve the money back after being constandly ignore and recieved 3 messages in almost 4 month with the words "no started yet :3" after i already paid them if they dont tell me why i have to wait so long after they told me it would take 3 weeks at maximum. I then understood the situation and waited 5 and a half months in total for one fullbody drawing with falsly drawn details and no information until the lineart has been finished, the artist said the drawing is done even tho i paid for a ref sheet and not a fullbody, which had a price difference. I then had to literally fucking explain the artist how to draw a ref sheet because they told me they never drew a ref sheet before and told me they almost never drew a dragon, but accepting a comission for a dragon ref sheet with no real references.
A friend told me the design was a "wolf with wings" which i also agree.

Cylia Miracle
Cylia always was meant to be the adoptive sister of Luwis. I dont have a backstory for her yet, but fact is she had been adopted when she was 8 years old. It took me almost 2 years to over come the fear of commissioning another ref sheet of her, as stupid as it sounds but i didnt wanted to pay another 70 bucks or even more at something with the same result. I atfirst asked a friend, who is an artist for an icon wit hthe importend detail for the head, later on a fullbody where the explained the others parts seperatly since the head was already finished so her body, tail and wings were next and seperated and after all of that the ref sheet. which i also did for my 3rd OC and it worked both wonderful.
I also changed her full name to Cylia Miracle. Her birth name is Cylia Voixy but her current name is Cylia Miracle

Pik Beta Version:
Pik was just a joke from a friend of mine but he started to advance the joke to a species and a character of his.
I liked the idea a lot so i took his species as my second OC, but sadly i already made finished design and oversaw the fact that their eyes must be bright and primary fur aswell

Pik The Bobby:
Nothing more to add honestly. Its characteristics got changed from an exhausted average person from stupidity to definition of my humour and stupidity

Leon Mirrow:
Like i said at the Luwis Miracle part, Luwis does not represent me,
I atfirst wasnt really sure of creating a character who should represent me, but i found the positioning very fitting as the 4th character since i saw myself like that: importend, but not that importend.
I think Goats are awesome, aswell as i really like goat beards and always look grumpy irl, so it is fitting with a goat to give him a grumpy face aswell.
Leon represents me fully, so he will also change over time if i do change aswell so he will get some ref sheets in the future.
Goats dont like water and i feel that

Amazing drawing made by the amazing  DoggettDouglasMcDog
Thanks to him for this gaint piece of art once again!
