We had been struggling to name all the characters for some time (with the
exception of Demona). I came up with the New York names and the rationale
that they had no names in the past. But that didn't seem to work for
Goliath. So we went with something classic. It appealed to me that Goliath
was named by the humans for an evil giant. A perfect indication that humans
didn't understand him (or gargoyles in general) at all.

I don't remember who chose the Coldstone name. It might have been me. Or it
might have been Michael Reaves who suggested it (or almost anyone on the show
for that matter). I know I came up with the Coldsteel and Coldfire names.
In early drafts of POSSESSION, Coldfire was called Goldfire, which was
another name I came up with. Finally the Coldfire name occurred to me.
It was obviously a better name, and I couldn't believe I hadn't thought of
it first. So I switched it. That was a bullet I dodged. (GDW/1-7-98)
