#6- In One Piece Magazine Vol.5, Oda drew a “what-if” illustration of Ace, Luffy, and Sabo as Marines. Garp was seen wielding a pair of katana swords.
#7- When he was a child and a young Marine, Garp resembled Luffy, though more muscular than his grandson. As a child, he wore a tropical button shirt with shorts and wielded a pipe staff. Garp already had the scar on his left eye in his childhood days.
#8- Oda drew Luffy’s possible appearances in his adulthood in two different timelines, at ages 40 and 60. Given how Garp resembled Luffy as a kid, it’s fitting that Luffy would resemble Garp as an old man.
#9- Garp shares some similarities with Smoker:
Both of them are Marine Vice Admirals.
Both of them have white hair.
Both of them are from East Blue.
Both cornered many times a certain pirate they were chasing (Roger for Garp and Luffy for Smoker).
Both of them are often accompanied by a swordsman (Bogard for Garp and Tashigi for Smoker).
Both of them have a scar on their face next to one eye.
#10- Due to his grudge against him, Chinjao wants Garp to suffer the pain of losing someone close to him. Ironically, Garp already underwent that pain upon losing Ace.
