Apollo is a very cool and commanding name. Especially since the god Apollo was the protector from evil.. and casper was a friendly ghost but a ghost all the same.
Apollo is also the god of light (basking). One of Apollo's tasks was to harness a chariot to drive the sun across the sky.
Draco -Latin for dragon, and is also a constellation in the sky.
Fido (had a cat named Fido once, and my friends thought it was a cute name for a cat, same would be true for a lizard)
Izzard-kind of cute name for a Lizzard...Izzy for short.
Ajax since he is lighter colored like ajax...call him Jax for short.
Ollie Just a cute all around name.
Dee Oh Gee... DOG...get it? pronounced DeeOhhhGe, emphasis on ohhhh. just a funny play on words. Especially since he is not a dog, but a pet all the same.
Edward Scissor Hand (from the movie) Edward or Eddie for short. We are always screaming about their long claws no matter how often they get trimmed. I also think Eddie is the name of the son in the Addams Family. You know, the whole idea of someone owning a creepy lizard, which he would have owned, only much bigger like their pet in the basement.
That's all I've got, for now.
