I have been playing DC for a long time.
And there have been a few dragons that have gotten a new look.
And there's a section for changing a dragon's skins and only a select few dragons have alternate skins.
I feel like some dragons could have "classic" skins for nostalgia's sake.
Here are a few examples I could find on the wiki
However I feel like the animations would look off since the older dragons had different animations.
Still, I would love to see them.
