What makes you say Garling isn’t prime? He should be same age as Roger/Garp/WB
If they are in there prime then Oda really did not make it seem so and did a poor job of showing it . ( the HK really suffer here )
WB and Roger clashing here so poor compare to Oden flashback .
Garp punching at WB , Kaido and BM look poor compare to beehive when he landed , WB not even use his powers on screen.
Then again that is what happen when you don't want to spend pages on action but few a small panels.
GV which suppose to be epic feel so small in scale with these shit action panels .
