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.

It would be a very good idea personnally

It's a very good idea, to remember the old days of DC
