Dragon

Dragons are a legendary creature from the myths of various Earth cultures.

The planet Berengaria VII had an indigenious animal that resembled Earth's mythological dragons. 

A species of dragon-like animal was the only creature that was able to withstand the harsh environments in the lower regions of Sema's home planet. (Dragon Ball Z vs. Star Trek: The Beginning of Infinity)

One of the creatures bred on Professor Gast's planet was dragons.

After been the butt of a joke by Terri Letac, Doctor Carol Murphy joked that were Letac to be trapped by a dragon during their medieval holodeck adventure that she would not come to her aid.

The USS Dragon was possibly named after the mythical creatures.
