I don't know what you mean but I will guess
On dragonvile u get 1 by breeding a fire and an ice dragon
to get a coolfire dragon and many other dragons is this: first you get a firebird(breed plant & ice) you breed it with ice when you have bred them you can get lots of cool dragons: soccer, dandleon, mojito, including coolfire it is the most safe way or you can try: to do it opposite, with a fire element and a ice hybrid. these ways are the best way and most likely you get a coolfire dragon.
The Leviathan Dragon is able to defeat a Coolfire dragon in the Dragon City.
you can get a legendary dragon, wind dragon or laser dragon. these 3 are only the ones I know
