I personally (although they are dragon like) don't like including the name dragon in the title however here are some:
Dragoman (the name of a travel company my cuzzie used to work for!)
Dragonman
Dragonish
Dragoling, Dragonling
A few various language Dragon names:
Naga- already used ; Bakonawa; Yilbegan; Scultone; Lindworm; Zomok; Vere Celen; Cuelebre; Zilant; Ejderha; Evren
What I intend to use, from Balaur (Romanian for Dragon)
The Balaur. Maybe Balaurian, Balaurive, something along these lines.
