Sadly I got into GWF about 1990/91 just as Earthquake was having his monster heel run in WWF. So I could never get into the GWF character’s name. I think I just called him Mattock in the early days and then added Chopper to it once he had his heel turn in the Workshop.
Earthquake is a special character in my fed - he won my 64 man tournament in 2091 (might have been 92 I forget) to become my first USFP United Stars Champion beating Pulsar Prime in the finals. The results were even posted in the Promoter. A big deal at the time!
