Characters who are way bigger than their parent or grandparent?

[Warmmedown]

Garp is bigger than Luffy
Morgan is bigger than Helmeppo
Roger is bigger than Ace? WB is too. Was WB shown to be much bigger than Roger in flashbacks?
Kaidou is bigger than Yamato (why is Yamato so much weaker?)

Roger was 3 feet taller than Ace lol. I guess his mother's genetics really brought him down.

Whitebeard was much larger than Roger. He was probably a Buccaneer to be that large.
