“Rambro” came from the movie, Hollywood Shuffle, a comedy movie where the lead actor did a skit of himself as the black Rambo. I added “Creed” simply because I felt like I needed a hobby ‘surname’ as well after a while. The selection of that came while watching rasslin’...this guy who went by Consequences Creed.
Picked “Creed” because I thought it sounded hard, rugged, and ‘wild cowboy’ like (even though I’m usually mild mannered most the time...then again, this is an alter ego).
Changed to Randall because I wanted a handle that sounded like it could be a real name.
And there you go.
