As per y’alls vote here are the FlurryVerse’s Fluttercord kids, Angel Shy and Cosmic Chaos!
 
After the most chaotic wedding of the century (we’re talking a whole Parasprite invasion, talking animals, Discord momentarily ruling Equestria for a few seconds), Fluttershy and Discord have led relatively quiet lives. Fluttershy keeps up her animal sanctuary, and she and Discord enjoy each other’s company in his realm on their off time. They were content with their lives–happy with just each other, and the idea of kids had never crossed their minds…until recently.  
After the defeat of Maredusa, Fluttershy has had nothing but foals on her mind. Maybe it was coming so close to defeat that prompted the thoughts, or just seeing the light in Twilight’s eyes when she was proud of Flurry, but Fluttershy knew she wanted some kids in her life. Discord–ever observant–picked up on Fluttershy’s longing and after a short discussion, a little bit of chaos magic led to their children. What followed was Fluttershy and Discord struggling to raise the first ever draconequus-pony hybrids (or draconys–as their parents lovingly put it); beings created of powerful magic capable of altering reality, shapeshifting, time traveling, and even changing their ages at will. In fact, a few days after they’re born, the foals become filly and colt–and a few days after, teenage ponies, forcing Fluttershy and Discord to navigate infancy, childhood, and adolescence all within the course of a week. Still, they’ll tell you it was worth it–nothing the Lord of Chaos and the Element of Kindness couldn’t handle. But who are these kids exactly?
 
Meet Angel Shy! Intuitive, kind, but a bit of a prankster, she shares her mother’s love for animals and nature but her father’s knack for practical jokes and casual mischief. She enjoys helping out at the sanctuary, shapeshifting into animals to talk to them and see their point of view, and loves pulling pranks and putting on shows with her magic.
 
Meet Cosmic Chaos! Loyal, thrill-seeking, yet occasionally devious, he considers himself the Prince of Chaos. He often butts head with Discord–not fully understanding what compelled him toward redemption–but is very close with Fluttershy and is able to listen to her voice of reason. His desire for troublemaking has once made him a threat, but he eventually turns around and understands the importance of friendship and love.
 
The twins are able to turn full draconquus and full pegasus, but usually remain in their given hybrid form. They can change age whenever they want to which lets them play a role in every character’s story, although they generally stick to their teenage form and stop switching around when they find their special someponies.
 

 
At first I didn’t think I’d have Fluttercord kids at all, but then these two came to me and they’ve since become part of the FlurryVerse. The story is inspired by Tommy and Billy from Wandavision, and how they’re able to age themselves at their own will. Seeing that Wanda and Discord are both reality-altering users of chaos magic, I thought something similar might go down for Fluttershy and Discord.
 
Also I have a cutie mark for Angel but I didn’t bother even trying to show a part of it since the wing makes it barely visible. As for Cosmic, I’m not sure yet, either i’ll figure it out along the way or he didn’t inherit the gene lol.
