seems like it
Luffy first used g4 on Doffy then during Cracker fight he probably used it mulpltipe times off screen
Same way he used g5 against Kaido then he's spamming it here at Egghead after every pause and meal
People downplay Cracker but look
It's stupid to think Luffy was fat for 11hrs
The dude was running and fighting after eating
Fat Luffy wouldn't do that
