You must be on suicide watch knowing Garp has trained many Marines lmfao. He is literally a Marine instructor right now.
How is this relevant though?
Your point is that he shits on other ACoC users which isn't true.
Sickbeard without ACoC was going to wreck the execution stand at Marineford.
Shiki destroyed half the town of Marineford while he fought Sengoku and Garp.
This is a CRAZY feat, and I honestly think Garp may still be over the Admirals somewhat after it, but y'all gotta calm down.
