That makes me wanna make a story for my OC and when I do, I will be sure to add her picture up here and give the full details of her :3

well I have some but really my main one that I use (since most of my Spyro-only FCs evolved into actual OCs) is Mikomi.
she is the daughter of Spyro and Cynder (yea I know, huge amount of creativity and uniqueness there right?! :D XD)
Name: Mikomi (Japanese for Hope)
Age:18
Gender: Female
Element: Fear, Poison, Fire, Earth
Appearance: she has mainly purple scales, with black tear drop like markings all over them. Her underbelly is black, with gold bolts of lightning coursing all around them. On her chest, is a scar, of three torn claw marks, obviously from a battle. Her horns are similar to Cynder’s, only gold like Spyro’s. One eye is Amethyst, the other Emerald. Her tail is similar to Cynder’s, only golden.
Personality: Very mature for her age, and wise. She is an elitist in battle, and has great knowledge of war and the past. She could easily be mistaken for a full grown adult with her personality.
Bio: She is from the future, a war-torn future where Black Eternal, a truly brutal tyrant has revived Malefor and together, the two of them have overthrown the dragon realms. And she, the only surviving child of Spyro and Cynder, had her father send her back in time, with his control over Dragon Time, in hopes of stopping this horrible future. The scar on her chest was taken in a battle between her, and one of Black Eternal’s many powerful children. For now, she is trying to keep up a normal appearance as a student of their Time, biding her time until she feels she is needed.

I'm gonna be taking inspiration from Spyro for a dragon-themed story / game later on, but he's not really gonna be a Spyro OC per se.

I haven't actually sat down and designed these characters yet but

Vaelysndr (or Lys for short)
Age unknown
Male
Light
Feral

Leaning towards a fluffy dragon, somewhere between Spyro and a wolf in shape, white with a grey-blue belly, spines, etc. He's about the size of a large dog. If I make a game the model will be Barbie, but it's impossible for me to design a male dragon without big privates so that's probably gonna be there. Blue balls jokes etc

Most of his powers derive from the concept of light. He can spit Mega Man pellets, charge them up to act more like fireballs with temporary light beacons on impact, and can use lenses to focus his light and set stuff on fire. He can also project a little bit of light out of his eyes to see better in the dark, and can "sneeze" to flash the area harshly and then keep it a bit brighter for a few seconds. Naturally, any such thing he does tends to give away his position.

I haven't made up a story for his game yet though, sorry.
