Good chapter! Poor Garp, it is sad to see him go after so many years, yet he for sure went out with a bang. Oda basically replicated WB and Marinford just in the span of a few chapters. If I have to make a critic I would say I would have given Garp something way more different than what he did for WB, also a bit longer. Now you can almost mistake him for a lesser WB.
Also... Where the heck is Bogard? Bogard is Garp right hand man, supposedly his Zoro, so did Oda just throw in him totally in the bin without any respect? Either way he will look like a joke if he ever reappears again, and I hope Oda will not try to throw some atrocious stuff like the Sabo amnesia.
Also I think this settles that Garp was the strongest marine alive despite his age (if, maybe, we leave out the mythic Kong).
