now that garp is retired i started wondering who is going to train coby now. and that got me thinking.Since we know that luffy is going to be the next pirate king(hopefully) is coby the one who is going to hunt him down. gold roger was hunted by garp. coby once said to luffy he would become an admiral so that means he will be strong. will coby be the one strong enough to hunt down luffy?
