So the Z'Gok can punch harder. I pity the GM that will face this thing

Actually, the GMs should be glad now because one of the rules of Gundam Fight is that you cannot aim at the cockpit.
Although there're a few exceptions;
-Z'God isn't exactly a gundam, right ?
-Targeting the cockpit is allowed in the tournament final.
-And only if the rules are followed, F.C. or not.
