You know, I want to say I love all my dragons equally, but that's a huge lie. I LIKE all of my dragons, but I have ones I clearly spoil.
Dosvidaniya, my iconic dragon and essentially myself in dragon form. She has all of my favorite style and color aesthetics, and I take any opportunity I can get to spoil her. While her lore and the money I've spent on her is relatively measly compared to some of my other dragons, she's my most spoiled dragon in comparison to how much I owe to her. She was the dragon that introduced me to my love for Ridgebacks and the Glimmer gene!
Proving Dosvidaniya's spoiled-ness, my two other favorite dragons are ones I've bought specifically in relation to her, since I love having trios of characters.
I wanted Dosvidaniya to have a companion, as at the time I was beginning to become way into Ridgebacks. I've always liked the Sentiment of Sanity accent, and I noticed that Platinum Cherub went perfectly with it. Thus
Zdravstvuyte came to be. While ideally I was seeking a mate or best friend character for Dos, Zdravstvuyte became more of a little sister figure for her. They contrast in aesthetic, but they get along great despite their differing origins. Plus, their names mean "Hello" and "Goodbye" in Russian.
Then, the color wheel update came, and upon finding a particular set of colors, I became focused on finding a dragon in those colors to finally become Dosvidaniya's lover.
Rasputin became my Dream Dragon goal, one that took over 3 months and several nests to obtain. Eldritch/Eggplant/Pear was a color combo that did not exist at the time, thus I was deadset on becoming the first to own one. With the help of a very generous fellow Plagueling, I rented nests and bought them dragons to breed in hopes of finding that perfect dragon.
Unfortunately, I wasn't the first to hatch an Eld/Egg/Pear, but that user was kind enough to let me buy it off them. I used that dragon as Rasputin's father, and as luck would have it, the very first nest he had upon maturing hatched two Eld/Egg/Pear babies (I wish I had kept the other one, but I only had one lair space left and was deadset on having a female dragon, and the nest owner opted to exalt him). Rasputin is my all-time favorite dragon in terms of outfit and colors, and to this day she remains the only active Eldritch/Eggplant/Pear dragon on the website alongside her father who I still own.
She's also probably my most expensive dragon, since I bought her outfit, her genes (sans Underbelly), a Scroll of Maturity (I was too excited to wait for her to grow up!), some pieces of art, as well as 1000+ gems to the very kind user who helped me breed her...
But since I went through all of this hard work and money to get a mate for Dosvidaniya, that's probably enough to show she's the top dragon in my heart.
