My very first toon on live was based on a GURPS Supers character I'd created years before (full on fire blaster) named Inferno. After trying millions (slight exaggeration) of iterations I gave up and tried On-Fire Dude (more as a joke than anything), and that's the name that stuck.
When I found Homecoming, that was again the first character I made.
As I played, I decided to make one of each archetype sticking, as much as possible, with the fire theme creating a plethora of alternate reality versions of my original concept. A Fire-Verse if you will.
