Dragon vs garling makes more sense than dragon vs akainu tbh
Garling is literally everything wrong with the WG that dragon wants to destroy.
He's a celestial dragon and CD putting him at the top of the WG the revs true target. He's even a former holy knight being the leader of them at 1 point in fact. The same group dragon said the real battle begins when they move making him dragons real enemy like twice over. Just look at how he talks about another CD who defended a Fishman, this is the kinda stuff that got the revolutionary army formed in the first place not to mention garling openly participates in events like the hunting at God valley which is hundred timed worse than ohara
Plus he was in the important people panel
