Dragons

Dragons are creatures featured on ABC's Once Upon a Time. There are overall two dragons in the show, along with a dragon puppet and a character named The Dragon. Dragons are scaly winged reptilian creatures that are generally hostile in most cases, and they breathe fire.

Dragon Puppet
At Martin and Myrna's puppet show, a dragon puppet is seen. The knight puppet encounters it, where he gets scared and when the dragon puppet, voiced by Myrna, asks who awoke her slumber, the knight comedically points out that the culprit went 'that way'.

Dragon of Midas' Kingdom
When David Nolan has to step in for his twin brother, James, he is sent on a quest with some of King George's other knights to slay a monstrous dragon that had been terrifying the kingdom of King Midas. However, when David realises that he is supposed to just be shown as the hero without actually doing anything and all the other knights are being killed by the dragon one by one, David fights and manages to behead the dragon, the head of said dragon is turned into gold by King Midas.

Maleficent
When David is sent on yet another quest, this time by Rumplestiltskin, he is required to hide a golden egg containing a bottle of true love inside the 'belly of a beast'. David goes to the Forbidden Fortress where he encounters the dark sorceress Maleficent. Just as David gets confused, Maleficent transforms into a huge black dragon. David and the black dragon
